Retirement withdrawal calculator

How long will the money last? Enter what you have, what you spend, and the Social Security or pension income that starts later, and the calculator walks year by year through retirement: spending rising with inflation, the portfolio earning a return, and each year's withdrawal grossed up for federal income tax — including the tax on Social Security benefits — so the spending figure is what you actually get to spend.

Each year the withdrawal is taken at the start, sized so that income plus withdrawal less federal tax equals the year's spending; what is left earns the return for the year. Ages are the age you reach in each calendar year, which is how the tax rules count them. The federal estimate applies the 2026 brackets and standard deduction, including the additional amount from 65 — raised each year by your inflation rate, as the IRS indexes them — to the pre-tax part of the withdrawal, the pension and the taxable share of Social Security under IRC §86; for 2025–2028 it adds the $6,000 senior deduction for each person 65 or over, each reduced by 6% of modified AGI over $75,000 ($150,000 on a joint return). Born in 1964, required minimum distributions from the pre-tax part begin at 75, taken in the year they fall due (the option of delaying the first one to April 1 of the following year is not modeled). Income above spending is kept outside the account too; growth on that outside money is not taxed in the estimate. It leaves out state income tax, itemized deductions, capital-gains treatment of a taxable account, Medicare premiums and IRMAA. A constant return is the largest simplification: the same average with bad years early runs out sooner. The senior deduction ends after 2028 unless Congress extends it.

The link keeps your inputs.

What happens in each year

Spending for the year is the first-year figure raised by inflation for every year elapsed.
Income that has started is added: Social Security is entered in today's dollars and rises with inflation both before and after it starts, as a COLA equal to inflation would make it; a pension is entered as the amount it will pay and rises only by the increase you give it.
The withdrawal is the amount that makes income + withdrawal − federal tax equal the spending, after any money kept outside the account has been spent. It is found by bisection, because the tax depends on the withdrawal.
Federal tax is computed on ordinary income = the pre-tax part of the withdrawal + pension + the taxable part of Social Security, less the standard deduction, at the 2026 rates. The brackets and the standard deduction are raised each year by your inflation rate, as the IRS indexes them; from 65 the additional standard deduction ($2,050 if unmarried, $1,650 per spouse on a joint return) applies, and for 2025–2028 the $6,000 senior deduction per person 65 or over, reduced by 6% of income over $75,000 ($150,000 on a joint return). The taxable part of benefits follows IRC §86 — half of benefits plus other income against the $25,000 / $32,000 base amounts and the $34,000 / $44,000 adjusted base amounts, with the 50% and 85% tiers — exactly as Publication 915's Worksheet 1 lays it out; those amounts are statutory and are not indexed.
Required minimum distributions apply to the pre-tax part of the account from 73 (75 for people born in 1960 or later; 1959 is read as 73 under the IRS's proposed regulations): the part's opening balance divided by the IRS Uniform Lifetime factor for the age reached that year, taken in that year — the option of delaying the first one to April 1 of the following year is not modeled. When the minimum exceeds what the year needs, the calculator withdraws it anyway, taxes it in full, and keeps the after-tax excess outside the account, where it is spent first in later years. A mixed account is kept as a pre-tax part and a Roth part: the minimum comes from the pre-tax part; the rest of each withdrawal is drawn from both in proportion to what each holds, and only the pre-tax dollars are taxed.
The balance after the withdrawal earns the return for the year. When neither the account nor the money outside it can cover the withdrawal, the year shows the shortfall and the plan is marked as running out at that age.

What is not in the estimate

State income tax, itemized deductions, and tax on the growth of the money kept outside the account.
Capital-gains treatment of a taxable brokerage account, which has no required minimum and is taxed on its gains rather than on withdrawals; "Roth" is the nearest approximation for one that would owe little tax.
Withdrawals before 59½: a 72(t) series of substantially equal payments avoids the 10% additional tax — see the 72(t) calculator.
Medicare premiums and IRMAA surcharges, long-term-care costs, and any change in spending pattern through retirement.
Variable returns. A constant return is a planning average; the same average with poor early years exhausts a portfolio sooner, which is what the safe-withdrawal-rate literature measures.

Questions this page answers

How long will $500,000 last in retirement at 62?

It depends on the withdrawal, the return and inflation. Drawing $20,000 in the first year and raising it with 2.5% inflation, at a 5% return, $500,000 lasts about 38 years before taxes; drawing $40,000 it lasts about 15 years. Social Security starting at 67 or 70 extends it, and federal tax on withdrawals from a traditional IRA shortens it — enter your figures above for the year-by-year answer.

Does the calculator include taxes?

Yes. Each year's withdrawal is grossed up so that income plus withdrawal less federal income tax equals the spending you entered. The estimate uses the 2026 federal brackets and standard deduction, indexed to your inflation rate, on the pre-tax part of the withdrawal, the pension and the taxable share of Social Security under IRC §86, with the additional standard deduction from 65 and the 2025–2028 senior deduction for each person 65 or over. State tax is not included.

Does it account for required minimum distributions?

Yes. From the applicable age — 73 for people born 1951–1959 (1959 under the IRS's proposed regulations, since the statute's two clauses overlap), 75 for people born in 1960 or later — the pre-tax part of the account must pay out at least its balance divided by the IRS Uniform Lifetime factor for the age reached that year. The calculator takes it in the year it falls due (the option of delaying the first one to April 1 of the following year is not modeled). When it is more than the year's spending needs, the calculator withdraws it, taxes it in full, and keeps the after-tax excess outside the account to be spent first in later years.
