Your result
Updates as you type. Based on 2025/26 UK figures where relevant.
How this is worked out
Your overtime rate is your normal hourly rate multiplied by the overtime multiplier. Multiply that by the overtime hours worked.
Tips
- Check your tax code on every payslip. 1257L is the standard code for 2025/26; anything else deserves a quick look in your HMRC app.
- Pension contributions and salary sacrifice reduce your taxable pay, which matters most if you're near a band threshold.
- If your income is between £100,000 and £125,140, you lose personal allowance and face an effective 60% marginal rate. Pension contributions can bring it back.
