What Is a Retirement Withdrawal Calculator?
A Retirement Withdrawal Calculator estimates how your
retirement savings may change when you withdraw a
regular amount of money for living expenses.
It can help you explore whether a portfolio may last
through a selected retirement period while considering
investment growth, inflation-adjusted spending, and
portfolio fees.
Unlike a simple calculation that divides savings by a
monthly withdrawal, this tool models the account month
by month so the remaining balance can continue earning
an assumed investment return.
How the Retirement Withdrawal Calculator Works
1
Enter Retirement Savings
Add the portfolio balance available when
retirement withdrawals begin.
2
Set Your Withdrawals
Enter your initial monthly spending amount,
retirement ages, return, inflation, and fees.
3
Review the Projection
See portfolio longevity, total withdrawals,
growth, and projected ending balance.
Next Year's Monthly Withdrawal =
Current Monthly Withdrawal × (1 + Inflation Rate)
The calculator increases the monthly withdrawal after
every completed year using the inflation rate entered.
Retirement Withdrawal Example
Suppose you retire at age
65 with
$750,000 in retirement savings
and begin withdrawing
$3,000 per month.
Starting Retirement Savings:
$750,000
Initial Monthly Withdrawal:
$3,000
First-Year Withdrawal:
$36,000
Initial Withdrawal Rate:
4.8%
Retirement Age:
65
Planning Age:
95
The calculator models the portfolio through the
selected retirement period. Investment growth is
added to the remaining balance while withdrawals
gradually increase with inflation.
What Affects How Long Retirement Savings Last?
Starting Portfolio
A larger retirement balance generally provides more
flexibility for withdrawals and may support a longer
retirement period.
Monthly Withdrawals
Higher withdrawals reduce portfolio assets more quickly.
Even a modest change in monthly retirement spending can
have a meaningful long-term effect.
Investment Returns
Positive returns can help offset withdrawals by allowing
the remaining portfolio to continue growing.
Inflation
Inflation can increase future spending needs. This
calculator increases the modeled withdrawal amount
each year using the inflation percentage entered.
Portfolio Fees
Investment and management fees reduce the return retained
by the portfolio and may affect how long retirement
savings last.
Understanding Your Retirement Withdrawal Projection
The projected ending balance shows how much of the
starting portfolio remains at your selected planning
age under the assumptions entered.
If the portfolio reaches zero before that age, the
calculator displays an estimated depletion age instead.
A projection that lasts through the selected age does
not guarantee that the same result will occur in real
markets because actual investment returns vary from
year to year.

Retirement Withdrawal Calculator FAQs
A Retirement Withdrawal Calculator estimates how a retirement portfolio may change while you make regular withdrawals. It can model investment growth, inflation-adjusted spending, portfolio fees, total withdrawals, and the estimated remaining balance.
How long savings last depends on the starting balance, withdrawal amount, investment returns, inflation, fees, and retirement period. This calculator models those assumptions month by month to estimate whether the portfolio lasts through your selected planning age.
Yes. The initial monthly withdrawal is increased after each modeled year using the annual inflation rate you enter.
If the modeled portfolio reaches zero before your selected planning age, the calculator displays the approximate age and time at which the portfolio is depleted.
Portfolio fees reduce the return retained by your savings. This calculator subtracts the annual fee percentage from the expected annual return before estimating monthly portfolio growth.
No. Actual investment returns, inflation, taxes, spending needs, market volatility, and fees can differ significantly from the assumptions entered. The calculator provides a mathematical estimate only.
