US Tax Bracket & Effective Rate Calculator
See how the progressive federal brackets stack up on your income, with your effective and marginal rates.
Progressive Bracket Visualization
This calculator shows how the progressive federal income tax actually works: it pours your taxable income into each bracket in turn and shows how much tax lands in each one. Enter your gross income, choose a filing status, pick the tax year and whether you take the standard or an itemized deduction, and it returns your estimated federal tax, your effective rate, your top marginal rate, and a bracket-by-bracket visualization. It is a planning estimate rather than a filed return, and it runs entirely in your browser, so nothing you enter is uploaded.
How the brackets are applied
The tool subtracts your deduction from gross income to find taxable income, then taxes each slice at its own rate. Every filing status has seven brackets from 10% to 37%. Standard deductions differ by year: for 2025 it uses $15,000 single, $30,000 married filing jointly, and $22,500 head of household; for 2026 it uses $15,350, $30,700, and $23,000.
Taxable = gross − deduction; Tax = Σ (income within each bracket × that bracket's rate)
For a single filer with $75,000 of income in 2026, taxable income is 75,000 − 15,350 = $59,650. The first $12,200 is taxed at 10% ($1,220), the next $37,400 at 12% ($4,488), and the final $10,050 at 22% ($2,211) — about $7,919 in tax. The effective rate is 7,919 ÷ 75,000 ≈ 10.6%, while the top marginal rate is 22%.
Effective rate vs. marginal rate
The result panel separates two numbers people often confuse. Your marginal rate is the bracket your last dollar lands in — useful for judging the tax on your next raise or bonus. Your effective rate is total tax divided by gross income, which is always lower because your early income is taxed at 10% and 12% before any higher rate applies. The stacked visualizer beneath the summary fills each bracket bar to show exactly how much income was taxed at each rate, and the take-home figure is gross income minus the estimated federal tax. Switching between standard and itemized lets you enter your own deduction total and see how a larger deduction shrinks taxable income.
Assumptions and limits
This estimate covers federal income tax only. It does not include Social Security and Medicare (FICA) payroll taxes, state or local income tax, tax credits, the Alternative Minimum Tax, or special treatment for capital gains and qualified dividends. The 2025 figures reflect the IRS's published amounts for that year, while the 2026 figures are the tool's estimates and may differ from the finalized IRS numbers, which are adjusted annually for inflation. Treat the output as information for planning, not as tax advice; your real liability depends on your complete return, and a tax professional can confirm the details.
Frequently Asked Questions
Does this tool save my income or send it anywhere?
No. All of the math runs in your browser. Your income, deduction and filing status are never uploaded or stored, and refreshing the page resets everything.
Why can I choose 2025 or 2026?
Because the brackets and standard deduction change each year. The 2025 option uses the IRS's published 2025 amounts; the 2026 option uses the tool's figures for that year, which may still be adjusted before final IRS guidance, so verify against official numbers for the year you file.
Should I use the standard or itemized deduction?
Most filers come out ahead with the standard deduction, but if your itemized deductions — such as mortgage interest, state taxes and charitable gifts — add up to more, itemizing lowers your taxable income. Switch the toggle and enter your total to compare the two.
Is this financial or tax advice?
No. It is for general information and planning only. Tax law and IRS figures change year to year and the result excludes FICA, state tax and credits, so consult a qualified tax professional before making decisions.
