Your result
Updates as you type. Based on 2025/26 UK figures where relevant.
How this is worked out
To add VAT, multiply the net price by the rate. To remove VAT from a gross price, divide by 1.2 (for 20%) to get the net figure; the difference is the VAT.
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.
