Coast FI & FIRE drawdown calculator

See what happens after you retire — not just when.

Most retirement calculators stop at the number you need to hit. This one keeps going: enter what you have today, and watch one continuous chart show your portfolio compounding through your working years, then spending down — every year, from today through age 100 — instantly, with no login and no email wall.

Growth compounds monthly while you contribute and annually once you're drawing it down. Spending is withdrawn at the start of each retirement year.

On track through age 100

Your money outlives you — with room to spare.

At $180K a year, the portfolio you retire with keeps growing instead of running down.

Portfolio balance, age 37 to 100

Logarithmic scale — the balance spans seven figures to eight, so equal steps up the axis mean equal proportional growth.

Balance every 5 years in retirement

Real (today's) dollars — no additional inflation adjustment needed on top of this.

This is a hypothetical, deterministic projection — it assumes the same real return every single year, which real markets never do (sequence-of-returns risk, especially in the first decade of retirement, is the thing this chart can't show you). It is not financial advice; consult a financial advisor before changing your contribution or withdrawal strategy. See the FAQ for how the math works.
