How long will my retirement savings last?

A systematic withdrawal plan does exactly what the name says: you sell a fixed amount every month and the rest stays invested. Vanguard and Fidelity have offered SWPs for decades — it's the standard way American retirees turn a portfolio into income without buying an annuity. Two questions decide whether yours works: how long will the money last, and what actually lands in your checking account after tax?

Most withdrawal calculators ignore the second question entirely. This one splits every withdrawal into your own contributions coming back (never taxed again) and capital gain, then applies the 2026 federal rules to the gain.

How the tax math works

For a taxable brokerage account, each year's realized gains stack on top of your other taxable income across the federal long-term capital-gains brackets — 0%, 15% and 20% — so your rate depends on your filing status and income, not a flat guess. The 3.8% net investment income tax is added on the portion above the statutory thresholds. For a traditional 401(k), the whole withdrawal is ordinary income at the rate you expect in retirement. Qualified Roth IRA withdrawals are tax-free.

The gain split uses pooled average cost — the standard planning simplification. State income tax is out of scope; several states add their own tax on gains.

Reading the depletion chart

Green bars show your projected balance at each year's end. If withdrawals outpace growth, the bars shrink and turn red the year the money runs out. If your withdrawal rate is modest relative to returns, the balance can outlive the projection entirely — and the calculator tells you which side of that line your plan sits on.

Frequently asked questions

How is each SWP withdrawal taxed in the US?

In a taxable account, only the capital-gain portion of each withdrawal is taxed. This calculator aggregates your gains for each year, stacks them on top of your other taxable income, and applies the 2026 federal long-term capital-gains brackets plus the 3.8% NIIT where it applies. 401(k) withdrawals are instead taxed entirely as ordinary income, and qualified Roth withdrawals are tax-free.

How is this different from the 4% rule?

The 4% rule is a rule of thumb for a starting withdrawal rate. An SWP projection shows the actual month-by-month path of your balance for your specific numbers — withdrawal amount, expected return, annual increases, and taxes — instead of a one-size heuristic.

Why does my tax change when I change my other income?

Because US capital-gains brackets are applied to your total taxable income. The same $20,000 gain can be taxed at 0% for a retiree with little other income and at 15% or more for someone still earning. That stacking is modeled correctly here rather than assuming one flat rate.

What does "originally invested" mean?

It's your cost basis — the total you contributed to build the portfolio. The difference between today's value and that number is unrealized gain, and only gain is taxed as you withdraw. If you don't know it exactly, your brokerage statement lists it; a rough number still beats ignoring tax entirely.
