Formula & Mathematical Methodology: VAT inclusive and exclusive formulas

Exclusive: tax = net × rate
total = net + tax. Inclusive: net = total ÷ (1 + rate)
tax = total − net.
Exclusive: tax = net × rate; total = net + tax. Inclusive: net = total ÷ (1 + rate); tax = total − net.
  • net: Price before tax
  • total: Price including tax
  • rate: The applicable rate selected by the user

Rounding: Rounded to 2 decimal places.

Worked Example: £1,000 before tax at 20%

A standard-rated United Kingdom supply is priced before VAT.

  1. Tax is calculated by multiplying the net amount by 20%.
  2. The tax is added to the net amount to get the total.
Result: The total is the net price plus VAT at the entered rate.

Frequently Asked Questions

How do I remove VAT from an inclusive price?

Select the inclusive mode and enter the applicable rate. The calculator divides the total by (1 + rate) to estimate the pre-tax value.

Which VAT rate should I use?

Rates depend on the goods or services and their circumstances. Confirm the applicable rate and treatment with the official tax authority before relying on the result.

Does this calculator determine whether my supply is taxable?

No. Select a treatment only after confirming the rules that apply to your supply.
