When to use this calculator
- Before accepting a pay change, bonus, pension contribution, or salary-sacrifice option.
- When you want to compare employed, self-employed, or dividend-based income scenarios.
- When you need a simple take-home estimate before running payroll or filing returns.
- When you are approaching the £100,000 income level and want to understand the personal allowance taper effect.
- When you are planning a salary sacrifice arrangement and need to see the net pay impact before agreeing terms.
A realistic US planning example
Use these sample inputs as a quick scenario test, then change one variable at a time to compare outcomes.
Annual Gross Salary ($)

Pay Frequency
Bi-weekly (26 paychecks/yr)
Filing Status
Single
401(k) Pre-Tax Contribution (%)
$250 per month
After entering these figures, review take-home per paycheck, annual take-home and federal tax/paycheck together rather than in isolation — each metric tells a different part of the story. Then rerun the tool with one input adjusted to see which variable has the biggest effect on all three outputs before you settle on a plan.
How to read your results
Take-Home per Paycheck
Use this metric to compare scenarios side by side and understand how changes in the key inputs drive the final outcome. If the figure surprises you, isolate one variable at a time and rerun the calculation to identify which assumption is responsible.
Annual Take-Home
Use this metric to compare scenarios side by side and understand how changes in the key inputs drive the final outcome. If the figure surprises you, isolate one variable at a time and rerun the calculation to identify which assumption is responsible.
Federal Tax/paycheck
Review this figure alongside gross income and the local tax rules that apply to you. It is a planning estimate, not a filing result or a recommendation to make a tax decision.
FICA/paycheck
Use this metric to compare scenarios side by side and understand how changes in the key inputs drive the final outcome. If the figure surprises you, isolate one variable at a time and rerun the calculation to identify which assumption is responsible.
Effective Rate
The effective rate lets you compare options on a true like-for-like basis rather than being misled by different compounding periods or fee structures. Use it to cut through headline marketing rates when shortlisting providers or products.
Method & assumptionsAuthoritative sources
This calculator estimates your US take-home pay using 2024 federal income tax brackets, the standard deduction ($14,600 single, $29,200 married filing jointly, $21,900 head of household), and FICA withholding rates of 6.2% for Social Security on wages up to $168,600 and 1.45% for Medicare on all wages. An additional 0.9% Medicare surtax applies to wages above $200,000 for single filers and $250,000 for married filing jointly. Traditional 401(k) contributions and employer-sponsored health insurance premiums are treated as pre-tax deductions that reduce your federal and state taxable income, as is standard for most US employer-sponsored plans.
State income tax is applied as a flat rate against your federal taxable income — this is a simplification since most states use progressive brackets, but it produces a useful estimate when you enter your effective state rate. The result does not include local city or county taxes, which can add 1% to 4% in cities like New York City, Philadelphia, or Columbus, Ohio. Your actual paycheck may differ depending on W-4 withholding elections, additional voluntary deductions, or employer-specific payroll processing. Always cross-reference with your pay stub for an accurate figure.
Common mistakes
- !Using an assumption that is not supported by a current local quote, bill, statement or official source.
- !Treating a generic estimate as a lender, provider, payroll or tax authority decision.
- !Mixing monthly and annual inputs without converting them consistently.
- !Forgetting location-specific taxes, fees, eligibility rules or payroll deductions where they apply.
- !Testing only one scenario instead of checking how a cautious assumption changes the result.
What to do next
- Run a second scenario with a cautious assumption so you can see the downside clearly.
- Compare the result with the related calculators below before making a decision.
- Check current local rules, eligibility and provider terms before applying or committing money.
- Keep a record of the assumptions so you can update the estimate when a quote, bill or pay figure changes.
- Use the result to prepare better questions for a lender, provider, adviser or employer rather than treating it as a final answer.
