— Corpus over retirement
Download— How it works
Income from corpus = corpus × your withdrawal rate, or the largest inflation-adjusted draw that lasts the horizon (ending at any legacy). Total income = corpus income + other income; net income applies a flat tax. All figures in today’s money.
Turning a pot into a pay-cheque
Your retirement income comes from two places: what your corpus throws off, and any guaranteed income like Social Security or a pension. The corpus part is a withdrawal: either you fix a rate (say 4% of the starting pot, rising with inflation) and see what it pays, or you ask the calculator for the most you can sustainably take across your whole retirement. Then it adds your other income on top and nets off tax to show your true monthly and annual income.
Worked example — $1,000,000 corpus, 5% return, 2.5% inflation, 30-year retirement: The maximum sustainable draw is about $46,300 a year ($3,855 a month) — a 4.6% rate. Draw a fixed 4% instead and it’s $40,000 from the corpus; add a $20,000 pension and your total income is $60,000 a year ($5,000 a month).
Fixed rate vs maximum sustainable
A fixed rate is simple and lets you compare against the 4% rule — but if the rate is higher than your corpus can support, the schedule shows the age the pot runs dry (your other income would continue). Maximum sustainable instead solves for the highest draw that lasts exactly your retirement length, depleting to zero — or, if you set a legacy equal to your corpus, the lower draw that preserves your capital intact. Either way the implied withdrawal rate is shown so you can sanity-check it against 4%.
The breakdown, and the caveat
Seeing income split into “from your corpus” and “from other income” is the point: guaranteed income shrinks how hard your savings have to work, and often makes a comfortable retirement reachable with a smaller pot. This is the mirror image of the Retirement Corpus calculator (income → corpus). As with every drawdown tool, it assumes a steady return and so ignores sequence-of-returns risk — a bad early market can undercut an income that looks sustainable on paper, so keep a margin.
— Reader questions
How much income will my retirement savings give me?
Roughly your corpus times a safe withdrawal rate, plus any pension or Social Security. A $1,000,000 pot sustainably yields about $46,000 a year (a 4.6% rate) over 30 years; add a $20,000 pension and your total is around $66,000.
What’s the difference between fixed-rate and max-sustainable?
Fixed-rate draws the percentage you set and shows whether it lasts (and the age it runs out if not). Max-sustainable solves for the largest draw that lasts your whole retirement — the answer to “what’s the most I can safely take?”.
Does other income reduce what I need from savings?
Yes — Social Security, a pension or rent is added on top of your corpus draw, so for a given target income your savings have to provide less. The breakdown shows exactly how much comes from each.
How do I preserve my capital instead of spending it?
Use max-sustainable mode and set the legacy equal to your corpus. The calculator then finds the lower draw that keeps your capital intact in real terms — a near-perpetual income you could leave to heirs.
Is this income guaranteed?
No. It assumes a constant return and ignores sequence-of-returns risk, so a poor run of markets early in retirement could undercut it. Treat the figures as a planning estimate and keep a safety margin.
