Understanding Your UK Take-Home Pay

This calculator provides an estimate of your net salary based on the 2024/25 tax year rules for England, Wales, and Northern Ireland.

⚠️ Scotland Notice

Scotland uses a separate set of income tax bands and rates. This calculator does not currently support Scottish tax rules. Projections for Scotland are coming soon.

Income Tax & The Taper

The UK uses a progressive tax system. Most people receive a £12,570 Personal Allowance. For every £2 you earn over £100,000, you lose £1 of this allowance. This creates a "60% effective tax trap" between £100k and £125k, which our calculator correctly identifies.

National Insurance (NI)

As of April 2024, the main rate of Class 1 employee NI has been reduced to 8% for earnings between the primary threshold and upper earnings limit. Our logic uses these latest 2024/25 rates.

Pension (Salary Sacrifice)

By default, this calculator assumes your pension contribution is made via "Salary Sacrifice." This means the contribution is taken from your gross pay before income tax is calculated, which is the most tax-efficient method.

Mathematical Logic

  1. Gross Pay: Starting annual amount.
  2. Pension Deduction: Calculated as a % of Gross.
  3. Taxable Income: Gross minus Pension contribution.
  4. Allowance Taper: If Taxable Income > £100k, reduce personal allowance.
  5. Income Tax: Apply 20%, 40%, and 45% bands to the Taxable Income.
  6. NI: Apply 8% and 2% bands to original Gross Pay.
  7. Student Loan: Apply respective Plan % to income above the threshold.
