If you withdrew KRW 12 million for living expenses during your first year of retirement, should you withdraw the same amount the following year?
Withdrawing the same amount makes living expenses easier to plan, but inflation may reduce the goods and services that money can actually buy.
Conversely, increasing withdrawals each year to match inflation may help maintain your standard of living. However, continuing to increase withdrawals during a market decline may cause your retirement savings to decrease faster than expected.
You may have already decided which asset to use for living expenses through a plan known as— a retirement withdrawal order—but you must separately review how much to withdraw each year.
Retirement withdrawal methods can generally be divided into fixed-amount withdrawals, inflation-adjusted withdrawals, fixed-percentage withdrawals, and variable withdrawals.
No single method is best for every retiree. The advantages and disadvantages vary according to living expenses, regular income, inflation, portfolio returns, and the remaining retirement horizon.
What Are Fixed and Variable Retirement Withdrawals?
Fixed withdrawals involve repeatedly withdrawing a predetermined amount or percentage according to an established schedule.
Common examples include withdrawing the same amount each month and withdrawing a fixed percentage of the current portfolio.
Variable withdrawals increase or decrease according to changes in market conditions, inflation, portfolio value, living expenses, and regular income.
Fixed withdrawals are easy to understand and make living expenses easier to plan. However, continuing to withdraw the same amount during a major market decline may place greater pressure on the remaining assets.
Variable withdrawals can respond to changing portfolio conditions, but the amount available each year may fluctuate and make spending plans less predictable.
A retirement plan may therefore use stable income and regular withdrawals to cover essential expenses while adjusting discretionary spending according to market conditions.
Four Retirement Withdrawal Methods
1. Fixed-Amount Withdrawals
A fixed-amount withdrawal involves withdrawing the same amount every month or year.
For example, if you decide to withdraw KRW 1 million each month during the first year, you continue withdrawing KRW 1 million each month regardless of whether the market rises or falls.
The main advantage is that the method is easy to understand and simplifies budgeting. It is also convenient for managing regular expenses such as rent, maintenance fees, and insurance premiums.
However, as prices rise, KRW 1 million buys fewer goods and services. The real purchasing power of the withdrawal may decline over time.
If you continue withdrawing the same amount during periods of low market returns, the withdrawal may gradually represent a larger percentage of the total portfolio.
Especially early in retirement, one major concern is— sequence of returns risk —because a market decline combined with fixed living-expense withdrawals can make it more difficult for the portfolio to recover.
Fixed-amount withdrawals provide predictable cash flow, but inflation and changes in the portfolio must be reviewed regularly.
2. Inflation-Adjusted Withdrawals
An inflation-adjusted withdrawal establishes the first-year amount and adjusts future withdrawals according to changes in inflation.
If you withdraw KRW 12 million during the first year and inflation rises by 3%, the second-year withdrawal would increase to KRW 12.36 million.
This method may help maintain the purchasing power of your living expenses.
However, increasing withdrawals because of inflation during a year when the portfolio has suffered losses may place greater pressure on the remaining retirement savings.
Applying the overall inflation rate directly to an individual’s entire withdrawal is not always accurate.
Even if overall consumer prices rise by 3%, an individual’s housing or medical expenses may increase by more, while spending in other categories may decrease.
When using inflation-adjusted withdrawals, review not only the official inflation rate but also the actual change in your essential living expenses.
3. Fixed-Percentage Withdrawals
A fixed-percentage withdrawal takes a predetermined percentage of the remaining retirement portfolio each year.
For example, if the portfolio is worth KRW 300 million at the beginning of the year and the withdrawal rate is 4%, the annual withdrawal is KRW 12 million.
If the portfolio declines to KRW 250 million the following year, applying the same 4% rate produces a KRW 10 million withdrawal. If it increases to KRW 350 million, the withdrawal rises to KRW 14 million.
Because withdrawals automatically decrease when the portfolio declines, this method reflects market conditions more directly than fixed-amount withdrawals.
However, a major market decline may also cause living-expense withdrawals to fall sharply. Retirees with substantial essential expenses may find this fluctuation difficult to manage.
During a year of strong returns, the withdrawal may increase too much. If the market later declines, it may be difficult to reduce the higher standard of living.
When using fixed-percentage withdrawals, you may therefore consider establishing minimum and maximum withdrawal limits.
4. Variable Withdrawals
Variable withdrawals increase or decrease according to predetermined criteria.
If returns are strong and the portfolio grows beyond its target, you may increase the withdrawal modestly. Conversely, if the market declines or the portfolio shrinks faster than expected, you may reduce discretionary spending and lower the withdrawal.
Variable withdrawals do not mean changing living expenses arbitrarily every year.
You should establish adjustment conditions, minimum living expenses, a maximum withdrawal amount, and review dates in advance and then follow those standards.
For example, you may use the following criteria:
• Maintain essential living expenses whenever possible.
• Suspend inflation increases for discretionary spending during a market decline.
• Adjust discretionary spending when the portfolio falls beyond a predetermined range.
• Avoid substantially increasing withdrawals before the portfolio recovers.
• Do not allow withdrawals to exceed the predetermined ceiling even when the portfolio grows.
Variable withdrawals allow flexible portfolio management but require annual calculations and reviews.
This method can be coordinated with— retirement portfolio rebalancing—to help adjust overweight assets while funding living expenses.
Differences Between Fixed and Variable Withdrawals
Fixed-amount withdrawals make annual income easier to predict, but they may not adequately reflect inflation or investment losses.
Inflation-adjusted withdrawals may help maintain purchasing power, but the withdrawal can increase even during a year when the portfolio declines.
Fixed-percentage withdrawals automatically reflect the current portfolio value, but living-expense withdrawals may fall sharply during a market decline.
Variable withdrawals can reflect markets, inflation, and actual expenses together. However, unclear adjustment rules may lead to emotionally driven decisions.
Therefore, withdrawal methods should not be compared on investment returns alone.
Consider spending stability, portfolio sustainability, ease of calculation, inflation protection, and your ability to manage changes in withdrawal income.
Five Criteria for Adjusting Withdrawals
1. Separate Essential Expenses from Discretionary Spending
First, divide retirement spending into essential expenses that must be paid and discretionary expenses that can be adjusted.
Essential expenses may include housing, food, utilities, basic insurance premiums, and necessary medical care.
Discretionary spending may include travel, hobbies, dining out, gifts, and vehicle replacement, whose timing and amount can be adjusted.
However, the same expense may be considered essential by one person and discretionary by another.
First determine how much of your essential expenses can be covered by regular income, such as National Pension benefits, retirement pensions, and rental income.
Cover any essential-expense shortfall with cash-equivalent assets and reliably accessible funds, while planning to adjust discretionary spending according to market conditions.
Even when withdrawals must be reduced during a market decline, cutting necessary medical expenses or basic housing costs may not be realistic.
When planning variable withdrawals, establish the minimum living expenses that must be maintained.
2. Compare Current Assets with Starting Assets
Determine how much the current portfolio has increased or decreased since the beginning of retirement.
Do not compare current and starting values without context. Also consider the living expenses already withdrawn and changes in inflation.
For example, if you began retirement with KRW 300 million and still have KRW 280 million after withdrawing living expenses for several years, the decline does not necessarily mean the portfolio was poorly managed.
Conversely, even if the account value remains similar, its real purchasing power may have declined because of inflation.
Also determine what percentage of the remaining portfolio is represented by the current withdrawal.
Current withdrawal rate = Planned net withdrawal for the year ÷ Current investment assets × 100
If the current withdrawal rate is substantially higher than originally planned, you may need to adjust discretionary spending, suspend an inflation increase, or review the target withdrawal itself.
3. Review Recent Returns and Market Recovery
A market decline does not mean that living expenses must be reduced immediately in response to a single day or month of price movements.
At a scheduled annual review, examine recent portfolio returns, current asset values, cash-equivalent assets, and future living-expense requirements together.
Maintaining a fixed withdrawal during a market decline may require selling more shares or units at lower prices.
You may consider suspending inflation increases for discretionary spending or postponing adjustable expenses such as travel or vehicle purchases.
You should also avoid immediately increasing withdrawals substantially simply because the market has risen.
If you raise your standard of living based on temporary gains, it may be difficult to reduce spending after a subsequent market decline.
When the portfolio grows during a market rise, determine whether it has recovered previous losses, increased in real value after inflation, and maintained its target asset allocation.
4. Review Inflation and Actual Spending Changes Together
As prices rise, more money is needed to maintain the same standard of living.
However, the official consumer inflation rate may differ from the increase in living expenses experienced by an individual.
Someone facing large increases in medical or housing costs may experience higher inflation than the average. Conversely, total spending may decline for someone who reduces travel and dining out.
A 3% increase in inflation does not mean that every spending category and the entire withdrawal must automatically increase by 3%.
Determine how much essential expenses have actually increased and adjust discretionary spending according to portfolio conditions.
Regular income must also be reviewed. Some income, such as National Pension benefits, may reflect inflation, while other income may remain unchanged each year.
If regular income rises with inflation, the additional amount required from investment assets may be smaller than the overall inflation rate suggests.
5. Review the Remaining Retirement Horizon and Expected Large Expenses
The longer the retirement horizon, the greater the effect current withdrawals may have on future assets.
Early in retirement, a substantial portfolio decline may create a greater need to adjust withdrawals because many years of future living expenses remain.
Later in retirement, consider the possibility of increasing medical, caregiving, and housing expenses.
Even if you reduce discretionary spending today, plan so that future medical expenses and emergency funds do not become insufficient.
Prepare separately for large anticipated expenses such as family support, home repairs, and vehicle replacement.
Before increasing a withdrawal for a large expense, ensure that sufficient essential living expenses and emergency funds will remain afterward.
Also review taxes and withdrawal restrictions. Withdrawing a large amount from a retirement account at once may change its tax treatment or payment conditions.
How Should You Determine the Initial Withdrawal?
With both fixed and variable withdrawals, an excessively high first-year amount may be difficult to correct later.
The net amount required from investment assets equals total annual living expenses minus National Pension benefits, retirement pensions, rental income, interest, and other regular income.
Net withdrawal requirement = Annual living expenses − Annual regular income
If annual living expenses are KRW 36 million and regular income is KRW 24 million, the net amount required from investment assets is KRW 12 million.
When reviewing the initial withdrawal amount, you may refer to a commonly used guideline— the 4% retirement withdrawal rule—as one point of reference.
However, 4% does not guarantee safety for everyone. Results may vary according to the retirement horizon, asset allocation, taxes, costs, inflation, and market returns.
If the required net withdrawal is too high relative to the current portfolio, choosing a different withdrawal method alone may not solve the problem.
You may also need to review living expenses, additional income, retirement timing, housing costs, and ways to use existing assets.
A Fixed and Variable Withdrawal Example
The following is a simplified example designed to explain the differences among withdrawal methods.
• Current retirement savings: KRW 300 million
• Total annual living expenses: KRW 36 million
• Annual regular income: KRW 24 million
• First-year net withdrawal requirement: KRW 12 million
• First-year net withdrawal rate: 4%
• Inflation rate the following year: 3%
• Portfolio value after the market decline: KRW 255 million
Fixed-Amount Withdrawal
You withdraw the same KRW 12 million as in the first year.
Although living expenses remain predictable, withdrawing KRW 12 million from a KRW 255 million portfolio produces a current withdrawal rate of approximately 4.71%.
The portfolio has declined while the withdrawal remains unchanged, so the percentage burden on the remaining assets increases.
Inflation-Adjusted Withdrawal
You apply the 3% inflation rate to the first-year withdrawal and withdraw KRW 12.36 million.
This may help maintain purchasing power, but the withdrawal rises to approximately 4.85% of the current KRW 255 million portfolio.
You must recognize that the market loss and the increase in withdrawals are occurring at the same time.
Fixed-Percentage Withdrawal
You withdraw 4% of the current KRW 255 million portfolio, which is KRW 10.2 million.
This automatically reflects the portfolio decline, but living-expense income falls by KRW 1.8 million from the first year.
You must determine whether the reduced amount can cover essential living expenses.
Variable Withdrawal
Suppose the first-year net withdrawal of KRW 12 million consisted of KRW 9 million in essential expenses and KRW 3 million in discretionary spending.
After the market decline, if you maintain the KRW 9 million in essential expenses but reduce discretionary spending from KRW 3 million to KRW 1.8 million, the total withdrawal becomes KRW 10.8 million.
Withdrawing KRW 10.8 million from the current KRW 255 million portfolio produces a withdrawal rate of approximately 4.24%.
This example illustrates how variable withdrawals work. It does not mean that discretionary spending must always be reduced by 40%.
The amount that can be adjusted varies according to each person’s essential expenses, regular income, health, taxes, and remaining retirement horizon.
Five Steps for Implementing Variable Withdrawals
Step 1. Establish a Baseline Withdrawal
Calculate annual living expenses and regular income to establish the baseline amount required from investment assets.
Include not only regular monthly expenses but also irregular costs such as insurance premiums, taxes, medical expenses, and vehicle repairs.
Step 2. Establish Minimum Living Expenses and a Maximum Withdrawal
Determine the minimum living expenses that must be maintained even during unfavorable market conditions.
Also establish a maximum withdrawal so that temporary investment gains do not cause spending to increase excessively.
Minimum living expenses and maximum withdrawals should reflect the individual’s regular income, portfolio size, and lifestyle.
Step 3. Establish Withdrawal Adjustment Conditions
Establish criteria for adjusting discretionary spending when the portfolio declines beyond a predetermined range or the current withdrawal rate rises substantially above the original plan.
Before increasing withdrawals after a market rise, establish criteria for confirming that previous losses have been recovered and the higher spending level is sustainable.
Step 4. Review the Plan on Scheduled Dates
Do not change withdrawals while watching the market every day. Review the plan on a scheduled date, such as every six or twelve months.
During each review, examine portfolio value, asset allocation, regular income, essential expenses, inflation, and expected large expenses together.
If a major financial change occurs, such as declining health or loss of income, you may recalculate the plan before the scheduled review.
Step 5. Record Decisions and Results
Record the withdrawal amount, essential expenses, discretionary spending, portfolio value, and current withdrawal rate before and after the adjustment.
Recording the reasons for increasing or decreasing withdrawals may reduce emotional decision-making when the market fluctuates again.
Also record the next review date and the conditions that would trigger another adjustment.
How Much Should You Reduce Spending During a Market Decline?
There is no rule requiring you to reduce living expenses by the same percentage as the market decline.
If the market falls by 20%, reducing every living expense by 20% may not be realistic.
First, determine how much of your essential expenses can be covered by regular income.
Next, identify discretionary expenses that can be postponed or reduced, such as travel, hobbies, dining out, gifts, and major purchases.
If sufficient cash and maturing investments are available for near-term needs, you may not need to sell investments urgently immediately after a market decline.
Conversely, if cash is insufficient and the withdrawal rate has risen substantially above the original plan, adjusting discretionary spending alone may not be enough.
You may need to review housing costs, insurance premiums, additional income, asset allocation, and the overall retirement plan together.
The key is not to reduce spending automatically whenever the market declines, but to calculate whether the plan remains sustainable with the remaining assets and then make an adjustment.
Can You Increase Withdrawals When the Market Rises?
If the portfolio has grown, you may be able to increase withdrawals modestly. However, avoid immediately raising your standard of living simply because the market has risen.
First determine whether the portfolio has merely recovered previous market losses or actually reached a new high.
Also determine whether its real value has increased after accounting for inflation.
When increasing withdrawals, distinguish one-time expenses from recurring fixed expenses.
A one-time expense such as travel is easy to discontinue, but recurring expenses such as rent, subscriptions, and insurance premiums continue even if the market declines again.
Even when increasing withdrawals during a market rise, do not exceed the predetermined maximum and confirm that the higher amount can be maintained the following year.
Advantages of Variable Retirement Withdrawals
1. They Can Respond to Market Declines
Adjusting discretionary spending after a major portfolio decline may reduce the need to sell an excessive amount of depressed assets.
2. They Can Reflect Inflation and Actual Living Expenses
Withdrawals can reflect not only official inflation but also changes in medical expenses, housing costs, and actual personal spending.
3. They Can Help Manage Portfolio Sustainability
Regularly reviewing portfolio value and withdrawal rates reduces the likelihood of continuing to withdraw a fixed amount without reassessment.
4. They Allow Flexible Spending Adjustments
You can maintain essential expenses while increasing or decreasing discretionary spending according to circumstances.
5. They Can Be Coordinated with Rebalancing
Coordinating living-expense withdrawals with asset-allocation adjustments may reduce unnecessary trading and help maintain the target risk level.
Limitations of Variable Withdrawals
Variable withdrawals do not guarantee that retirement savings will never be depleted.
If a market decline continues for an extended period or the initial withdrawal is excessively high, the portfolio may decline rapidly even after reducing discretionary spending.
If essential expenses represent a large portion of spending, there may be little that can actually be reduced.
Because assets, living expenses, and taxes must be calculated each year, variable withdrawals are more complex to manage than fixed-amount withdrawals.
Without predetermined adjustment rules, you may easily increase withdrawals when the market rises but fail to reduce them when it declines.
Declining cognitive ability or health may also make a complex variable withdrawal plan difficult to manage independently.
Therefore, simplify the calculations, maintain clear records, and create a system that can be reviewed with family members or a qualified professional when necessary.
Seven Common Mistakes
1. Changing Living Expenses After Every Small Market Decline
Frequently changing living expenses in response to short-term price movements makes it difficult to maintain a long-term plan.
Use scheduled review dates and predetermined adjustment criteria.
2. Failing to Separate Essential and Discretionary Spending
Reducing every expense by the same percentage may leave insufficient money for necessary medical care or housing costs.
3. Increasing Every Expense at the Full Inflation Rate
Increasing the entire withdrawal at the inflation rate without reviewing actual spending changes and regular income may result in withdrawing more than necessary.
4. Increasing Withdrawals Too Much During a Market Rise
Turning temporary investment gains into recurring fixed expenses may make it difficult to reduce spending after the market declines.
5. Failing to Recalculate the Current Withdrawal Rate
If you review only the initial withdrawal rate and fail to calculate the rate relative to current assets, you may overlook the increasing risk as the portfolio declines.
6. Ignoring Taxes and Costs
Even when withdrawing the same amount, taxes, trading fees, and early termination costs may vary according to the account and financial product.
7. Failing to Record Adjustment Rules
Without written criteria, you may make different decisions each time based on market conditions and emotions.
Questions to Review Before Adjusting Withdrawals
• What are my total living expenses for this year?
• What is my net withdrawal requirement after regular income?
• How much do I spend on essential and discretionary expenses?
• What is the minimum amount required for essential living expenses?
• What percentage of my current assets does the withdrawal represent?
• How much has the portfolio increased or decreased since the last review?
• Has the portfolio recovered from previous market losses?
• Has real purchasing power increased after inflation?
• Has regular income also increased with inflation?
• Are medical expenses or other large costs expected in the near future?
• Which discretionary expenses will I adjust first if withdrawals must be reduced?
• Can a higher withdrawal be maintained the following year?
• Have I reviewed taxes and the withdrawal conditions of each financial product?
• Have I recorded the next review date and adjustment criteria?
If you adjust withdrawals based only on market returns without answering these questions, actual living expenses and the long-term retirement plan may become misaligned.
Which Is Better: Fixed or Variable Withdrawals?
Fixed withdrawals may be convenient for someone who needs predictable living expenses and wants to minimize complex calculations.
However, inflation, portfolio changes, and the current withdrawal rate must still be reviewed regularly.
Variable withdrawals can respond to market and spending changes, but they require clear criteria and discretionary expenses that can actually be adjusted.
You do not have to choose only one method.
You may use a combined approach: cover essential expenses with National Pension benefits, retirement pensions, and fixed withdrawals while adjusting discretionary spending such as travel and hobbies according to market conditions.
The goal is not to find the method that provides the highest withdrawal. It is to cover necessary living expenses while preventing the remaining retirement savings from declining too quickly.
ConclusionConclusion
Fixed-amount withdrawals simplify living-expense planning but may not respond adequately to inflation and market declines.
Inflation-adjusted withdrawals may help maintain purchasing power, but the withdrawal can increase even when the portfolio has declined.
Fixed-percentage withdrawals reflect current asset values, but living-expense income may change substantially during a market decline.
Variable withdrawals separate essential and discretionary expenses and adjust the withdrawal according to markets, inflation, regular income, and the remaining retirement horizon.
Regardless of the method used, regularly review the initial withdrawal, current withdrawal rate, asset allocation, taxes, and costs.
The key is not to predict the market’s direction, but to establish withdrawal adjustment rules in advance and manage both living expenses and the sustainability of retirement savings.
This article provides general financial information and does not recommend any particular withdrawal rate or method. Actual withdrawal decisions may vary according to an individual’s financial circumstances, living expenses, regular income, taxes, investment horizon, and risk tolerance.
