VAT Overview

VAT is a tax that is levied on the sale of goods or services. It is an integral part of the GDP of any country and comes under the Indirect tax.

VAT is a multi-stage tax that is imposed on sales and purchases at each stage of production of goods or services. If the annual turnover of a business exceeds a certain (UK- £85,000) threshold, VAT must be paid on the supply of goods or services.

VAT Calculation Formula

Follow the steps given below to calculate Value Added Tax (VAT) or Reverse VAT on the price of a product or service:

VAT Amount = Total Amount – Net Amount

Add VAT = Total Amount = Net Amount + (Net Amount × VAT Rate)

Remove VAT = Net Amount = Total Amount ÷ (1 + VAT Rate)

Total Amount = Net Amount + VAT Amount


  • VAT Amount: The amount of VAT that is added to the selling price (for regular VAT calculations) or subtracted from the selling price (for Reverse VAT).
  • Selling Price: The price of a product or service before VAT is applied.
  • VAT Rate: The percentage rate at which VAT is charged. Make sure the VAT rate for calculation is in decimal form.

To use this formula for regular VAT calculations, you need to multiply the sales price by the VAT rate divided by 100.

Example for VAT Calculation

Assume a product or service costs £50,000 and the VAT rate is 20%.

1: VAT Amount: £50,000 × (20 / 100) = £10,000

2: Add VAT: £50,000 + VAT Amount = £50,000 + £10,000 = £60,000

3: Remove VAT: Amount – (Amount × (1 / (1 + VAT rate / 100)))

VAT amount: £50,000 – (£50,000 × (1 / 1.20)) = £8333.33

Amount without VAT = (£50,000 × 0.833333) = £41,666.67
