Savings Rate Calculator
Find what share of your income you save each month.
How much of your income you keep
Your savings rate — the share of income you save rather than spend — is the single biggest driver of how quickly you build wealth, outweighing small differences in investment returns. This calculator makes it plain.
Saving 800 of a 4,000 monthly take-home is a 20% savings rate. Push it higher and the years needed to hit a goal shrink sharply, because you both save more and need less to live on.
Motivating and private
It divides savings by income in your browser, so your figures stay on your device with nothing uploaded.
