Tips for best results

  • Use Reverse VAT mode when you want to see and understand the actual formula behind the calculation, not just the answer.
  • Your last-used VAT rate is remembered in your browser, so you don't need to re-select it every visit.
  • The VAT rate presets are common general rates — always confirm the applicable rate for your specific jurisdiction before relying on the result.

Common mistakes to avoid

  • Assuming the preset VAT rates are automatically correct for your country and situation — confirm your actual applicable rate.
  • Filling in the Business Name/Invoice Reference/Notes fields and expecting them to show on screen — they only appear in the downloaded PDF report.
  • Using Add VAT mode on a price that already includes VAT — check which mode matches your actual starting amount to avoid double-counting.
