Federal + State Tax Calculator

Federal, state, local and payroll tax combined. The effective rate across all four layers is the number that describes what you actually pay, and it is always well below the marginal rate.

Also called: total tax burden calculator, effective tax rate.

Total effective rate
28.45%

28.45% of gross income goes to tax, $42,675.00 in all. Your combined marginal rate is 30%, so the next dollar keeps 70 cents. Take-home is $107,325.00.

Computed from the published rates for the tax year you selected, which is not necessarily the current year. A calculation, not tax advice, and it does not know anything about your circumstances beyond the figures entered.

Method and background

This is what the calculation gives for the numbers you entered. It is an estimate, not advice, and it knows nothing about your situation beyond those numbers. Rules for United States change on a published schedule; the effective date is shown on every rule-based tool.

How this is calculated

Each layer is added and divided by gross income to give the effective rate. The marginal rate is the sum of the federal and state marginal rates and describes what happens to the next dollar rather than the average across all of them. Confusing the two is the most common error in tax conversation: a twenty-four percent bracket does not mean twenty-four percent of income goes to federal tax. Payroll tax is included because it is a real deduction, and for lower incomes it is often the largest single component.

Method and limits

What it assumes

  • The tax figures supplied are computed elsewhere and simply combined here.

What it deliberately does not model

  • State income tax is deductible federally subject to the SALT cap, which this does not net off.
  • The employer half of payroll tax is not shown, though it is economically part of your cost.

Frequently asked questions

Why is my effective rate so much lower than my bracket?
Because brackets are marginal. Only the income inside the top bracket is taxed at that rate, and everything below it is taxed at lower rates.
