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.
Gross Annual Income ($)
$55,000
Filing Status
Single
Your Age

Deductions
Standard Deduction
After entering these figures, review federal income tax, fica (ss+medicare) and total tax 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
Federal Income Tax
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 (SS+Medicare)
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.
Total Tax
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.
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.
Take-Home Pay
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.
Monthly 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.
Method & assumptionsAuthoritative sources
This calculator estimates your 2024 US federal income tax liability using the IRS marginal bracket system. Taxable income is your gross income minus either the standard deduction (set by the IRS for each filing status) or your total itemised deductions, whichever applies. Tax is then calculated tier by tier across the seven brackets — 10% through 37% — so only the portion of income that falls within each bracket is taxed at that rate. FICA taxes (Social Security at 6.2% up to the $168,600 wage base and Medicare at 1.45% on all income) are added separately, as these are payroll taxes rather than income taxes and are not reduced by deductions. The Additional Medicare Tax of 0.9% applies above the income thresholds shown.
Results are estimates only and do not account for tax credits (such as the Child Tax Credit, Earned Income Tax Credit, or education credits), alternative minimum tax (AMT), self-employment tax adjustments, or investment income surtaxes. Tax law changes frequently; always verify bracket and deduction figures at IRS.gov or with a qualified CPA for your actual filing. This tool is designed for W-2 wage earners and may not accurately reflect situations involving significant self-employment, capital gains, or foreign income.
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.
