Tax Bracket Calculator
Split 2025 federal tax into owed, marginal, and effective rates.
What it does
Two rates describe every tax bill and they rarely match. The marginal rate prices the next dollar of overtime or deductions, while the effective rate shows what share of income the government actually keeps. Confusing them turns decent decisions into expensive ones.
The tool above splits them with 2025 federal bands. Enter filing status and taxable income to get tax owed, marginal rate, and effective rate. Defaults put a single filer at $60,000, so the page opens solved at $8,114.00 with 22% marginal and 13.52% effective.
The arithmetic is pleasantly mechanical: $1,192.50 plus $4,386.00 plus $2,535.50. Only the top $11,525 tastes 22%; everything below pays 10 or 12%. Joint filers run the same machine with wider bands, so $100,000 joint owes $11,828.00 at the same 22% margin but a lower 11.83% average.
Practice runs show the curve bending: $30,000 single owes $3,361.50 at 12% marginal with 11.21% effective. Each extra band lifts the margin while the average trails behind, which is exactly why raises never lose money to brackets alone.
Use the table for landmarks, then run your income. The page models 2025 federal ordinary income only; state tax, gains rates, AMT, credits, and the standard deduction all sit outside. Within range it answers the two questions that matter: what does the next dollar cost, and what share is already gone.
How to use
- Pick single or joint filing status.
- Enter 2025 taxable income.
- Read tax owed first.
- Read marginal rate for next dollar choices.
- Read effective rate for the big picture.
- Rerun joint versus single to compare.
Formula
- Status
- Filing status: single or married filing jointly.
- Income
- 2025 federal taxable income in dollars.
- Tax
- Total federal ordinary income tax.
- Marginal
- Rate on the top dollar.
Bands follow 2025 federal Revenue Procedure 2024-40 for single and joint filers as republished by the Tax Foundation. Only ordinary taxable income is modeled; capital gains, AMT, credits, and the standard deduction sit outside. Income of zero owes zero with a zero effective rate.
Worked example
Example: single $60,000 in 2025
Single filer with $60,000 of 2025 taxable income. Find federal tax, marginal rate, and effective rate.
- Single 2025 brackets: 10% to $11,925, 12% to $48,475, 22% to $103,350.
- First slice: 11925 x 10% = $1,192.50.
- Second: (48475 - 11925) x 12% = $4,386.00.
- Third: (60000 - 48475) x 22% = $2,535.50.
- Total = $8,114.00. Marginal 22 %, effective 13.52 %.
- Joint $100,000 gives $11,828.00 at 22 % marginal.

Questions
What is the marginal rate?
The rate on the next dollar earned. At $60,000 single it is 22%, even though the average rate is only 13.52%.
What is the effective rate?
Total tax divided by income. The example pays $8,114 on $60,000, about 13.52%.
Is all income taxed at the top rate?
No. Brackets apply at the margin: only dollars inside each band pay that band rate. Most income is taxed below the top rate.
Does it cover joint filers?
Yes. Pick joint: $100,000 joint owes $11,828.00 at 22% marginal with 11.83% effective.
Which income do I enter?
Taxable income after adjustments and deductions, not gross pay. Standard deduction and credits sit outside this page.
Does it include state tax?
No. These are 2025 federal ordinary income bands from Revenue Procedure 2024-40. State taxes need their own tables.
