Savings Rate Signal

How much of your income are you keeping?

This calculator tells you what percentage of monthly take-home income remains after spending and whether that savings rate is red, yellow, or green.

Calculate your savings rate

Use income after taxes and payroll deductions.
Include bills, debt payments, and discretionary spending; exclude money moved to savings or investments.

Savings rate and financial independence

A higher savings rate does two things at once: it builds invested assets faster and implies a smaller lifestyle to fund. The simplified table below starts from zero and assumes constant spending, a 5% annual return after inflation, and a target equal to 25 years of annual spending—the common 4% rule.

The table is a static illustration, not a forecast. Returns, taxes, fees, existing assets, pensions, and spending changes can move the result substantially.

The signal thresholds and 4% rule are common rules of thumb, not financial advice.

Savings rate questions

What should I count as income?

Use monthly take-home pay: the money reaching your accounts after taxes and payroll deductions. If it varies, use a representative monthly average.

What should I count as spending?

Include all monthly outflows for living costs, bills, debt payments, and discretionary purchases. Do not count transfers to savings or investments as spending.

Can my savings rate be negative?

Yes. If spending exceeds take-home income, the result is negative. That means cash reserves or new debt are covering the monthly gap.

Does the financial-independence table predict my future?

No. It is a simplified illustration. It does not know your existing balance, taxes, returns, future spending, or other income.
