How to Use This Effective Tax Rate Calculator

The Formula
Federal Tax = Tax on (Gross Income β Deduction) using 2025 brackets
State Tax = Gross Income Γ State Rate (simplified flat-rate approximation)
FICA (Employee) = min(wages, $176,100) Γ 6.2% + wages Γ 1.45% [+ 0.9% over $200K]
FICA (Self-Employed) = SE Net Γ 15.3% β 50% SE tax deduction from income
Total Effective Rate = (Federal + State + FICA) Γ· Gross Income Γ 100
State Tax = Gross Income Γ State Rate (simplified flat-rate approximation)
FICA (Employee) = min(wages, $176,100) Γ 6.2% + wages Γ 1.45% [+ 0.9% over $200K]
FICA (Self-Employed) = SE Net Γ 15.3% β 50% SE tax deduction from income
Total Effective Rate = (Federal + State + FICA) Γ· Gross Income Γ 100

Frequently Asked Questions
What is the difference between effective and marginal tax rate?
Your marginal tax rate is the rate on the last dollar you earn β the highest bracket you are in. Your effective tax rate is your total tax divided by total income, which is always lower because lower portions of income are taxed at lower rates. Most people confuse their marginal rate for their effective rate, significantly overestimating how much tax they pay.
What is included in the total effective tax rate?
A complete picture includes: federal income tax, state income tax, and FICA taxes (Social Security 6.2% + Medicare 1.45% = 7.65% on wages). Some analyses also include local taxes and sales taxes. Self-employed workers pay 15.3% SE tax (both employer and employee shares) instead of 7.65%.
What is the FICA tax?
FICA (Federal Insurance Contributions Act) includes Social Security tax (6.2% on wages up to $176,100 in 2025) and Medicare tax (1.45% on all wages, plus 0.9% Additional Medicare Tax on wages over $200,000 single / $250,000 married). Your employer also pays 7.65%, bringing the total to 15.3% on your wages.
How do states differ in income tax?
State income tax rates vary significantly. Texas, Florida, Nevada, Washington, Wyoming, South Dakota, and Alaska have no state income tax. California has the highest top rate at 13.3%. Most states have graduated brackets like the federal system. Some states like Pennsylvania have a flat rate (3.07%).
What is the Additional Medicare Tax?
The Additional Medicare Tax is an extra 0.9% on wages over $200,000 (single) or $250,000 (married filing jointly). It applies to the employee only β employers do not match this. It also applies to self-employment income and net investment income (NIIT, which is a separate 3.8% tax on investment income for high earners).
