How to Use
- Toggle the switch to Add VAT (price excludes tax) or Subtract VAT (price already includes tax).
- Enter the amount in your local currency.
- Set the VAT or sales tax rate as a percentage (UK 20%, EU often 19–25%, Saudi Arabia 15%, most US states 4–10%).
- Read the VAT amount, net (pre-tax) figure, and gross (with-tax) total. Cross-check against your profit margin to ensure VAT isn't quietly eating it.
Formula Explained
Total = Amount × (1 + VAT Rate / 100)
- Amount
- = The price you start from — net if adding VAT, gross if subtracting
- VAT Rate
- = Statutory rate as a percentage (e.g. 20 for 20%)
Worked example: Adding 20% UK VAT to £100 net: total = £100 × 1.20 = £120 (VAT = £20). Extracting 20% VAT from a £120 gross price: net = £120 / 1.20 = £100.
