How This Calculator Works
The calculator optionally subtracts your standard deduction, then pours your taxable income through the 2025 federal brackets from the bottom up. Only the dollars that land inside each bracket get taxed at that bracket’s rate — which is why moving into a higher bracket never shrinks your take-home pay.
Total tax = sum of (income inside each bracket × that bracket’s rate)Your marginal rate is the bracket your last dollar lands in. Your effective rate is total tax ÷ taxable income (after the deduction) — always lower than the marginal rate under a progressive system.
Assumptions baked into the math
- 2025 federal brackets and standard deductions ($15,000 single / $30,000 married filing jointly).
- Ordinary income only — long-term capital gains and qualified dividends use their own, lower rate schedule.
- Federal income tax only. State income tax and FICA (Social Security and Medicare) are on top of this.
- No tax credits or itemized deductions — those can lower the real bill further.
A worked example
A single filer earning $75,000 takes the $15,000 standard deduction, leaving $60,000 taxable. That’s 10% on the first $11,925, 12% on the next $36,550, and 22% on the last $11,525 — $8,114 in total. The marginal rate is 22%, but the effective rate on taxable income is just 13.5%. The scary bracket number and the real bill are very different things.
Frequently Asked Questions
What is the difference between marginal and effective tax rate?
Your marginal tax rate is the rate on your last dollar of income — the bracket you're in. Your effective tax rate is the actual percentage of your total income that goes to taxes. Because the U.S. uses progressive brackets, your effective rate is always lower than your marginal rate.
How do tax brackets work?
The U.S. uses a progressive tax system. You don't pay your marginal rate on all your income — only on the portion that falls within each bracket. For example, a single filer earning $60,000 pays 10% on the first $11,925, 12% on the next $36,550, and 22% on the remaining $11,525.
What is the standard deduction for 2025?
For 2025, the standard deduction is $15,000 for single filers, $30,000 for married filing jointly, $15,000 for married filing separately, and $22,500 for head of household. Most taxpayers benefit from taking the standard deduction rather than itemizing.
Does this include state taxes?
This calculator shows federal income tax only. State income taxes vary widely — some states have no income tax (Florida, Texas, Nevada), while others have rates up to 13%+ (California). Your total tax burden is federal + state + FICA (Social Security and Medicare).
How can I lower my tax bill?
Common strategies include maximizing pre-tax retirement contributions (401k, Traditional IRA), using Health Savings Accounts (HSAs), harvesting investment losses, timing income and deductions, and taking advantage of tax credits. Cash Flow Explorer covers these in detail.
