Savings Rate Calculator
Find your personal savings rate — the share of income you actually keep — and see how many years of expenses it buys each year.
How it works
Savings rate = amount saved ÷ take-home income × 100 · Years banked per year = saved ÷ spent
Your savings rate is the single most powerful number in personal finance: the share of what you earn that you keep. Because a higher rate simultaneously grows your investments and shrinks the lifestyle they must eventually support, it drives your timeline to financial independence far more than investment returns do. Saving 20% of income banks a quarter of a year of expenses for every year worked; saving 50% banks a full year for every year — which is why the same rate roughly predicts how long until work becomes optional.
Worked example
Saving $1,000 out of $5,000 take-home is a 20% savings rate. You spend $4,000 and save $1,000, so each year of work stores away about 0.25 years of expenses — the intuition behind why a 50% rate cuts a career roughly in half.
Frequently asked questions
Should savings rate use gross or net income?
Either can work as long as you are consistent, but net (take-home) income is the more honest denominator for personal budgeting. Using gross income makes the rate look lower because taxes are counted as income you never received.
Does an employer 401(k) match count?
Yes — matched contributions are money saved on your behalf, so many people include both their own contributions and the match in the numerator. Just note whether you are also adding the match to income to keep the ratio consistent.
What savings rate should I aim for?
Financial-independence guidance often targets 25–50%+, while a common baseline for a comfortable retirement is around 15–20% of income. Any increase helps: raising your rate cuts spending and lifts investing at the same time.
