Model retirement withdrawals
Simulate portfolio drawdown over time using your retirement savings, withdrawals, inflation assumptions, and expected annual return during retirement.
Your retirement withdrawal results will appear here
Calculate to see how long your money may last, whether your full retirement plan is funded, remaining balance at the end, total withdrawals taken, and estimated run-out timing if funds deplete early.
Your withdrawal sustainability
A retirement withdrawal plan is sustainable when the portfolio can support your spending for the full period you need, not just for the first few years. That is why this page focuses on balance trajectory, run-out risk, and spending durability over time. If you want a faster rule-of-thumb check, compare your results with the 4% Rule Calculator. If you want to see whether your savings target is large enough before retirement begins, compare with the Retirement Goal Calculator and Retirement Savings Calculator.
Good durability
Your projected balance survives the full retirement period and still has money left at the end.
Borderline durability
Your plan lasts most of retirement but small changes in return, inflation, or spending could cause problems.
Weak durability
The portfolio runs out early, suggesting the withdrawal amount may be too aggressive for the assumptions used.
How retirement drawdown works
Retirement drawdown is the decumulation phase. Instead of adding to the portfolio, you are taking money out while hoping the remaining balance still earns enough return to help support future spending. This is very different from growth-focused tools like the Investment Growth Calculator, Compound Interest Calculator, and Wealth Projection Calculator, because the direction of cash flow has changed.
During accumulation
- Contributions add to portfolio value
- Time works with compounding on a larger base
- Temporary downturns can sometimes be offset by continued investing
- Focus is often on ending balance growth
During drawdown
- Withdrawals reduce the balance available to grow
- Returns matter more because the capital base is shrinking
- Bad early years can cause lasting damage
- Focus shifts to sustainability and money duration
Balance first
The larger the starting portfolio, the more room the plan has to absorb withdrawals and volatility.
Withdrawal size
Even small increases in spending can shorten portfolio life more than many retirees expect.
Return sequence
Early weak returns combined with withdrawals can accelerate depletion risk.
Time horizon
A 20-year retirement and a 35-year retirement can require very different withdrawal discipline.
Monthly vs annual withdrawals explained
Some retirees think in monthly income because bills arrive every month. Others think in annual spending because it makes long-term planning easier. Both approaches are valid, but the math should match the way withdrawals actually happen. This calculator converts your selected frequency into a period-by-period simulation so the results are easier to interpret.
| Withdrawal style | Best for | Planning benefit | Things to watch |
|---|---|---|---|
| Monthly withdrawals | Household budgeting and paycheck-style retirement income | Feels closer to real retirement cash flow | Long-term annual sustainability can be harder to see without conversion |
| Annual withdrawals | Retirement planning and strategy comparison | Clear for long-range drawdown analysis | Needs translation into monthly lifestyle terms |
If you are still deciding what retirement lifestyle is realistic, compare the results here with the Expense Calculator, and Passive Income Calculator.
How long will your money last?
The answer depends on several connected variables: your starting savings, withdrawal size, return assumption, inflation, and retirement length. A portfolio that looks strong under fixed spending can fail under rising withdrawals. A plan that works at 6% returns may struggle at 3%. This is why retirement withdrawal planning works best when you test scenarios instead of relying on one perfect estimate.
Higher spending
Larger withdrawals shorten portfolio life because less capital stays invested to support future withdrawals.
Lower returns
Weak returns can significantly reduce how long a retirement portfolio lasts, especially in the first decade.
Longer retirement
A longer retirement horizon raises the burden on the portfolio and requires more durable withdrawal planning.
Inflation pressure
Rising withdrawals preserve purchasing power but can strain sustainability if portfolio growth does not keep up.
You can also compare these retirement durability results with forward-looking target tools like the Time to Reach Goal Calculator, Future Value Calculator, and Present Value Calculator.
Remaining balance over time
Many people focus only on whether the first year of retirement income looks affordable. A stronger way to think about retirement is to monitor the path of the remaining balance. Depletion risk often develops gradually. The plan may look comfortable early on, then weaken later as inflation raises withdrawals or returns disappoint.
Early years
The portfolio may still look stable even if the long-term path is weaker than expected.
Middle years
This is often where rising withdrawals and compounding on a smaller balance begin to show their effect.
Late years
If the balance drops too low, even modest spending can become harder for the portfolio to support.
Inflation and rising withdrawals
Taking the same nominal amount every year is simple, but it can quietly reduce your purchasing power over time. Inflation-adjusted withdrawals try to preserve lifestyle by increasing spending periodically. The trade-off is that rising income can put more pressure on portfolio longevity. If you want to think about real returns instead of nominal returns, use the Annualized Return Calculator for comparison.
Fixed nominal withdrawals
You withdraw the same amount each period. This is easier on the portfolio but may buy less over time.
Inflation-adjusted withdrawals
Your withdrawals rise over time to help maintain purchasing power. This is more realistic for lifestyle planning but often reduces sustainability.
Return assumptions during retirement
Return assumptions are one of the most sensitive parts of retirement planning. Using an unrealistic number can make a fragile plan look safe. That is why many retirees compare several return cases instead of relying on a single estimate. If you want to understand how different investment performance assumptions change the big picture, compare results with the Portfolio Performance Calculator, ROI Calculator, Annualized Return Calculator, and Investment Growth Calculator.
Conservative case
Useful for checking whether your plan still works if returns are lower than expected.
Base case
A reasonable middle scenario for planning, not a promise of actual returns.
Optimistic case
Helpful for comparison, but risky if used as the only retirement assumption.
Withdrawal stress test scenarios
Stress testing helps reveal whether your retirement plan is robust or overly dependent on favorable assumptions. A plan that only works when everything goes right may not be durable enough. Compare your base result with tougher conditions to see how quickly sustainability changes.
| Scenario | Return assumption | Inflation assumption | Withdrawal change | What it tests |
|---|---|---|---|---|
| Base retirement plan | Your selected return | Your selected inflation | No change | Current expected outcome |
| Lower return case | 1% to 3% lower | Same | No change | Portfolio resilience in weaker markets |
| Higher inflation case | Same | 1% to 2% higher | Inflation-adjusted | Purchasing power pressure |
| Higher spending case | Same | Same | 5% to 10% more | Lifestyle creep and withdrawal strain |

What causes retirement money to run out?
Retirement portfolios rarely fail because of one single issue. Depletion usually happens when multiple pressures combine: withdrawals start too high, returns disappoint, inflation lifts spending, and the retirement period lasts longer than expected.
Too much spending early
Heavy withdrawals in the early years reduce the capital base that future returns depend on.
Ignoring longevity risk
Many retirement plans underestimate how long money may need to last.
Weak market periods
Bad returns during drawdown can hurt more than during accumulation because money is being removed at the same time.
No flexibility
Plans can become fragile when spending cannot adjust after poor results or higher living costs.
Flexible vs fixed withdrawal strategies
Some retirees prefer a steady withdrawal plan. Others build flexibility into spending so they can withdraw less during difficult years. A flexible strategy can improve portfolio longevity because it reduces pressure when balances fall. A fixed strategy is simpler, but it may ignore changing market conditions and household needs.
Fixed strategy
- Easier to budget
- Clear expectations for spending
- May work well with pensions or other predictable income
- Can become stressful if markets weaken
Flexible strategy
- Can improve sustainability
- Lets spending adapt to portfolio health
- Useful when retirement income sources vary
- Requires discipline and regular review
Common retirement withdrawal mistakes
Using one perfect estimate
Strong retirement planning usually requires comparing multiple scenarios, not betting everything on one assumption set.
Ignoring inflation
A flat withdrawal may look sustainable on paper while quietly reducing real lifestyle purchasing power.
Assuming high returns forever
Overly optimistic return assumptions can make a weak withdrawal plan appear safer than it really is.
Not reviewing spending
Retirement is not static. Spending, health costs, housing, and taxes can change over time.
Separating retirement from the full financial picture
Retirement drawdown works best when it is connected to your budget, assets, and other income sources.
Overlooking opportunity cost before retirement
If you are still building savings, tools like the Time to Reach Goal Calculator, Future Value Calculator, and Compound Interest Calculator can help improve readiness before withdrawals begin.

Frequently asked questions
Your retirement savings may last anywhere from a few years to your full retirement period depending on starting balance, withdrawal size, returns, inflation, and longevity assumptions. This calculator tests those factors together instead of using a simple shortcut.
A realistic retirement withdrawal calculation simulates each period, applies return to the remaining balance, subtracts the withdrawal, and repeats until the retirement horizon ends or the balance reaches zero.
A safe withdrawal amount depends on your retirement length, inflation, return assumptions, spending flexibility, and other income sources. A rule of thumb can be helpful, but personalized simulation is often more informative. Compare with the 4% Rule Calculator for a quick reference point.
Withdrawing too much reduces the remaining balance faster, leaves less money invested for future growth, and can significantly shorten how long the portfolio lasts.
Inflation-adjusted withdrawals can better preserve your purchasing power, but they also increase pressure on the portfolio. Many retirees compare both fixed and rising withdrawal paths before choosing a strategy.
Higher returns can help support withdrawals for longer, while lower returns can cause the balance to run out earlier. Return assumptions matter even more during drawdown because money is leaving the portfolio at the same time.
A 4% rule calculator uses a rule of thumb. A retirement withdrawal calculator simulates how your own portfolio behaves over time based on specific withdrawal, inflation, return, and retirement horizon inputs.
Yes. This calculator supports monthly and annual withdrawal frequency so you can model retirement cash flow in the way that makes the most sense for your planning.
If the portfolio runs out before the full retirement period, the result suggests that your current withdrawal plan may not be sustainable under those assumptions. You may need lower withdrawals, higher savings, more flexible spending, or different retirement timing.
More flexibility generally improves sustainability. Retirees who can trim discretionary spending during weaker years often have more durable plans than those who must spend the same amount regardless of portfolio performance.
