Formula and method
Gross = net × (1 + rate / 100). Net = gross / (1 + rate / 100).
Worked example
At 20%, a net price of 100 becomes 120; a gross price of 120 contains 20 tax.
What the result assumes
Enter the rate applicable to your purchase. No country-specific rates, exemptions, or tax filing rules are assumed.
Common question
Why not subtract 20% from the gross price?
Included tax is calculated on the net price. Dividing by 1.20 reverses a 20% tax correctly.
