How it works

  • Tax-excluded → tax-included: the entered net price is multiplied by the tax rate to get the tax amount, which is then added to the net price for the gross total.
  • Tax-included → tax-excluded: the gross price is divided by (1 + rate) to recover the net price, and the difference is shown as the tax amount.
  • Tax rates vary widely by country and region (for example, many countries apply a standard VAT plus a reduced rate for essentials). Use the preset buttons or enter any custom rate that applies to you.
  • The rounding option controls how the tax amount's fractional part is handled: round down, round half up, or round up. Real invoices may use different rounding rules per merchant or jurisdiction.
  • Displayed amounts are rounded estimates. Official invoiced or remitted tax may differ depending on transaction terms and local rounding rules.
