Savings Rate Calculator
Measure how much of your monthly take-home income you keep for savings, investing, or additional debt repayment.
Quick answer
Enter monthly take-home income and the amount directed to saving. The calculator returns your savings rate and the monthly amount needed for your target rate.
Formula used
Savings rate = monthly amount saved ÷ monthly take-home income × 100.
Worked example
Saving $750 from $5,000 of take-home income gives a 15% savings rate. A 20% target would require $1,000 per month, a $250 difference.
How to interpret the result
Definitions vary. This version uses after-tax income and lets you decide whether retirement contributions and extra principal payments count as savings.

Frequently asked questions
Should employer retirement contributions count?
You may include them if you want a total compensation view, but use the same definition every month for a meaningful trend.
Can my savings rate be negative?
If spending exceeds income, your effective savings rate is negative. This calculator accepts only the amount actually saved, so record zero and review the shortfall separately.
Is 20% the correct target?
It is a common budgeting reference, not a universal requirement. A sustainable rate aligned with your goals is more useful than one fixed number.
