Where your income goes

Tax 17.1%Take-home 82.9%

Your effective rate spreads your total tax across all of your income, so it is usually lower than the marginal rate on your last dollar.

How the effective tax rate works

Your effective tax rate answers a simple question: of every dollar you earned, how many cents went to tax? You divide the total tax you paid by your total income and multiply by 100. The leftover share is your take-home rate, the part you actually keep.

This single number is more useful than your tax bracket for budgeting, because it reflects how the whole progressive system, plus your deductions and credits, applied to all of your income rather than just the last dollar.

A quick example

If you earned $85,000 and paid $14,500 in tax, your effective rate is 14,500 ÷ 85,000, which is about 17.1%. You keep the remaining 82.9%, or $70,500. Even if your top bracket were 22%, your effective rate stays well below it.

Things to keep in mind

Make sure your income and tax figures cover the same period and the same definition of income. For current brackets, deductions and credits, the Internal Revenue Service is the authoritative source. Estimate your full picture with our other free calculators.

Frequently asked questions

What is an effective tax rate?

Your effective tax rate is the share of your total income that you actually pay in tax. It is found by dividing total tax by total income. Because lower brackets tax your early income at lower rates, the effective rate is usually below your top bracket rate.

How is it different from the marginal tax rate?

The marginal rate is the rate applied to your last dollar of income, which is your top tax bracket. The effective rate blends every bracket together across all of your income, so it is a better measure of your overall tax burden.

Should I use gross or taxable income?

Both are valid, but be consistent. Dividing tax by taxable income shows the rate on what was actually taxed, while dividing by gross income shows the rate against everything you earned. Pick one and use it for every comparison.

Why is my effective rate lower than my bracket?

Tax systems are progressive, so only the income inside each bracket is taxed at that bracket's rate. Deductions and credits lower the tax further. The result is an average rate that sits below the top bracket you reach.
