BucketSavers

Same savings, same spending, same strategy — the only thing you don't get to choose is the year you retire into. Every start year since 1928, run against what the market actually did. Everything runs in your browser.

Your retirement

A bucket-strategy retiree (spending cash first, growth last). Change anything; all of history re-runs instantly.

Safe buffer

Front buckets earn actual T-bill rates; the reservoir earns the actual S&P 500 total return, year by year. During real drawdowns (index below its prior peak) refills pause and rebuilds are gradual — the same rules as the bucket simulator.

How the math works

What runs under the hood

This is the bucket simulator's engine pointed at real history instead of assumptions: S&P 500 total returns, 3-month T-bill rates, and CPI, 1928–2025 (NYU Stern / Damodaran data). Your spending starts at the amount you set and rises with each year's actual inflation — retirees in 1974 got an 11% cost-of-living raise whether they liked it or not. Front buckets earn that year's T-bill rate; the reservoir earns that year's S&P total return. "In a drawdown" is observable, not assumed: the total-return index sits below its prior peak, refills pause, and rebuilds happen gradually — rules a real retiree could actually follow.

What the colors mean

Red: the money ran out before your plan-to age. Amber: it survived, but finished below your starting balance in nominal dollars — decades of spending consumed most of it. Green: it survived with the starting balance intact or better. All figures are nominal; a 1928 dollar and a 2025 dollar are very different things, which is why the story panel talks about depletion and drawdowns rather than comparing ending balances across eras.

Why the same plan lives or dies

Sequence-of-returns risk, made concrete. The average return of the market since 1928 barely varies across 30-year windows — but retiring into a decade that opens with a crash plus inflation (1966, 1929, 1973) means selling assets at depressed prices to fund withdrawals that inflation is raising, and the portfolio never recovers its footing. Retiring into 1982 means the opposite. Same behavior, same spending discipline, wildly different endings. The buffer you set above is the knob that buys time through the bad openings; watch how the red years respond to it.

What this tool is not

Not a prediction — 98 years of history is one draw from the universe of possible futures, and includes nothing worse than the Great Depression, nor anything better than the postwar boom. No taxes (the withdrawal-order and marginal-rate tools carry that side of the story), no fees, no Social Security or pensions offsetting withdrawals, annual granularity only, and no behavior changes mid-retirement — this retiree never cuts spending, which real people do. The point is the spread of outcomes, not any single cell.
