Savings Rate Calculator

Of every pound that lands in your account, how much do you keep? It's the one number that quietly drives everything else.

Monthly take-home pay

Saved or invested each month

Count everything that builds your future: savings, investments, pension contributions you make yourself, and mortgage overpayments.

*Starting from zero, using the classic shorthand: 5% real returns, spending stays steady, and a 4% withdrawal rate. It's a compass, not a countdown — theFIRE calculator lets you use your real numbers.

Why this number matters so much

Your savings rate does two jobs at once: every extra percent both grows your pot fasterand proves you can live on less — which shrinks the pot you'll eventually need. That's why moving from 10% to 20% doesn't halve the journey to financial independence… it cuts it by more.

There's no "good" or "bad" here. A 5% rate while you clear expensive debt is genuinely excellent; a 40% rate that makes you miserable won't last. Find the number you can hold calmly, then nudge it upward when life allows.

This calculator is a general educational tool. It uses simplified assumptions, isn't personalised financial advice, and shouldn't be the only basis for a money decision — see our Disclaimer. For decisions that matter, consider speaking to a suitably qualified, regulated adviser.
