How to Calculate VAT at 20%

If you have a gross amount and want to determine the net value simply divide the gross value by 1.20 and this provides the value without VAT included. For example, an invoice that includes VAT totalling £150 would have a VAT amount of £25 and the net would be £125 - this is calculated by dividing £150 by 1.2 which gives the net value of £125 - the difference being the VAT at 20%.

If you have figure you want to add VAT to, multiply by 0.20% to find the VAT value or 1.20 to find the gross value including VAT. For example an invoice of £125 multiplied by 20% provides a VAT figure of £25.

The net amount is the value you use in your accounts for purchases and sales if you are a VAT registered company.
