Savings Rate Calculator

Find out what percentage of your after-tax income you're saving each month — the single most useful early metric in personal finance.

What actually lands in your account each month.

Everything you spend in a typical month.

Currency

Enter your monthly income and expenses to see your savings rate.

How it works

Your savings rate is the share of after-tax income you keep rather than spend. It's simple, but powerful: the higher your savings rate, the more room you create to save, invest and handle surprises. This tool subtracts your monthly expenses from your monthly income and expresses the difference as a percentage.

The formula

savings rate = (income − expenses) ÷ income × 100

A concrete example

If you take home $3,800 a month and spend $3,000 on everything, your savings rate is (3800 − 3000) ÷ 3800 = 21.1%. You're keeping $800 a month, or $9,600 a year.

What this calculator does not tell you

  • The calculator treats every non-expense dollar as "saved", including irregular or one-off outflows.
  • Two people with the same savings rate can have very different financial situations — context matters more than the number alone.
  • This is an educational estimate, not a financial plan.

Disclaimer

This calculator provides a general educational estimate based entirely on the values you enter. It is not financial, investment, tax or legal advice, and it is not personalized. Prices, rates and market conditions change. Check with a qualified professional before acting on any estimate. Full disclaimer and our methodology.

Frequently asked questions

There is no universal target. For many personal finance writers a benchmark of 15–20% of gross income is common for retirement saving, but your rate depends on your income, costs and goals. More important than hitting any number is saving consistently and increasing your rate over time. See our article on savings rates for a full explanation.
