How is take-home pay calculated in United Kingdom?

We start with your gross salary, apply the United Kingdom personal allowance and any standard deductions, run the result through the 2025/26 progressive income tax brackets, then subtract mandatory employee social-security and equivalent contributions. The number left is your annual and monthly net pay.

Does this include social security and other payroll deductions in United Kingdom?

Yes. The United Kingdom calculator models employee-side social security, pension, health, and any solidarity or surcharge components that apply to wages. Employer-side contributions are excluded because they don't reduce your take-home pay.

Is the United Kingdom calculator accurate for my situation?

It's a single-filer wage estimate that uses official 2025/26 rates. Your actual tax can differ based on filing status, dependants, regional or municipal taxes, salary-sacrifice arrangements, capital gains, and other personal credits. Treat the result as a strong first estimate, not tax advice.

What's the effective tax rate on a £100,000 salary in United Kingdom?

At £100,000 gross per year, the model returns an effective tax-and-social-security rate of about 27.4% and a marginal rate of about 40.0% — leaving roughly £68,557 as annual take-home. Enter your own salary above for a tailored breakdown.
