The calculator applies 2025 IRS progressive brackets to your taxable income. Taxable income is gross income minus your deduction (standard or itemized) and any above-the-line adjustments.
Taxable Income = Gross Income − Deduction − Above-Line Adjustments Federal Tax = Sum of (Income in bracket × Bracket rate) Effective Rate = Total Tax ÷ Gross Income Marginal Rate = Rate of the bracket containing the last dollar

Who Is This Calculator For?
Job seekers comparing offers
Enter each salary to see the after-tax difference. A $10,000 raise from $90,000 to $100,000 adds only $7,800 after 22% federal tax.
W-2 employees checking withholding
Verify your year-end tax liability before the filing deadline to avoid an unexpected balance due.
Freelancers and 1099 workers
Estimate the federal portion of quarterly estimated payments. Note that self-employment tax adds another 14.13% on top of income tax.
Anyone who received a raise
Find the exact take-home from a raise. Not the stated gross increase but the net amount you actually keep.
Investors with ordinary income
Check whether interest, non-qualified dividends, or rental income pushes you into the next bracket before you receive it.
Tax-year planners
Model whether deferring or accelerating income or deductions before December 31 changes your bracket or effective rate.
How to Use the Calculator
1
Enter annual gross income
Type total W-2 wages, self-employment income, or any ordinary income before deductions. Add multiple sources together.
2
Select your filing status
Single, Married Filing Jointly, Married Filing Separately, or Head of Household. Each has different bracket thresholds and standard deduction amounts.
3
Choose standard or itemized
Standard deduction is automatic. Choose itemized only if your qualifying expenses exceed the threshold. The calculator uses whichever is higher.
4
Add above-the-line deductions
Enter traditional IRA contributions, student loan interest, HSA contributions, or other qualifying adjustments. These reduce taxable income on top of the standard deduction.
5
Read your results
The results card shows total tax, effective rate, marginal rate, and a bracket-by-bracket breakdown with a proportional bar for each bracket.
6
Test different scenarios
Change your income or deductions to model the tax impact of a raise, IRA contribution, or filing status change before you commit to it.
Worked Example: Sarah, Registered Nurse, $78,000
Sarah earns $78,000 as an RN, files single, takes the $14,600 standard deduction, and contributes $3,500 to a traditional IRA.
Gross income$78,000
IRA deduction (above-the-line)- $3,500
Standard deduction- $14,600
Taxable income$59,900
10% on first $11,925$1,193
12% on $11,926 to $48,475$4,386
22% on $48,476 to $59,900$2,514
Total federal income tax$8,093
Effective rate ($8,093 / $78,000)10.4%
Marginal rate22%
The $3,500 IRA contribution saved Sarah $770 in federal tax (the $3,500 was in the 22% bracket). Without it, her taxable income would have been $63,400 and her tax $8,863. Her effective rate would have climbed to 11.4%.
Common Mistakes to Avoid
!
Applying marginal rate to all income
Earning $78,000 does not mean you owe 22% on all $78,000. The 22% bracket only applies to income above $48,475. The first $11,925 is still taxed at 10%.
!
Forgetting the standard deduction
You never owe tax on the first $14,600 of income as a single filer. Entering gross income without applying any deduction overstates your federal tax significantly.
!
Excluding above-the-line adjustments
Traditional IRA contributions, student loan interest, and HSA deposits reduce taxable income even when you take the standard deduction. Leaving these out inflates your tax estimate.
!
Treating FICA as income tax
Social Security (6.2%) and Medicare (1.45%) are separate from income tax. For a $78,000 salary, FICA adds another $5,967 on top of federal income tax.
!
Using the SALT cap wrong
State and local taxes are capped at $10,000 total when itemizing. If you paid $14,000 in state income and property taxes combined, only $10,000 is deductible.

Pro Tip
The 22% bracket starts at $48,475 for single filers. Maxing a $23,500 traditional 401(k) at $70,000 gross pushes $1,525 of income from 22% back into the 12% bracket, saving an extra $153 on top of the base bracket difference. At $85,000 gross, all $23,500 sits in the 22% bracket, saving $5,170 in federal tax alone.
