About this tool
This saving rate calculator measures your personal saving rate — income minus spending, divided by income — the single most important number in personal finance.
Unlike total savings, the rate scales with your income and therefore tells you how fast you are building freedom relative to your lifestyle. Track it monthly; small improvements compound across decades.

The percentage of your after-tax income you keep instead of spending. $1,000 saved from $4,000 income is a 25% saving rate.

10-15% is common advice; 25-30% puts you on track for early retirement. The rate matters more than the amount for building wealth.

Mathematically, a higher saving rate shortens your career: 25% takes about 32 years, while 50% can reach the same fund in about 17 years.
