How to calculate VAT
Adding VAT
The calculation for adding VAT is:Multiply the net amount by the VAT rate to find the tax
For example: £100 × 0.2 = £20This gives you a VAT amount of £20 and a gross total of £120
Removing VAT
To remove VAT you calculate:Divide the total (gross) amount by 1 plus the VAT rate to get the net value
For example: £100 ÷ 1.2 = £83.33This gives you a net total of £83.33, with the remaining £16.67 as VAT

Is VAT Calculated on net or gross?
VAT is calculated on net value, after you add VAT tax to your net value it becomes a gross value
Is it possible to calculate the cost of a product knowing only the VAT amount?
Yes – you can work out the original cost if you only know the VAT amount.
If a product costs £100 and you apply a standard VAT rate of 20% to it, the amount of VAT will be £100 x 0.2 = £20
Let’s say you don’t know the cost of the product X, but you know that the VAT paid was £20, the formula will be 0.2X=£20, therefore X=£20/0.2, X=£100
If a product costs £100 and you apply a standard VAT rate of 20% to it, the amount of VAT will be £100 x 0.2 = £20
Let’s say you don’t know the cost of the product X, but you know that the VAT paid was £20, the formula will be 0.2X=£20, therefore X=£20/0.2, X=£100
What is the flat rate scheme?
VAT Flat Rate Scheme (FRS) is a simplified method of accounting for VAT which is convenient for small businesses. Instead of calculating and reclaiming the VAT on each purchase and sale separately, you simply pay a fixed percentage of your business’s turnover to HMRC. The flat rate percentages range from 4% to 14.5%, depending on the business sector. We have a blogpost that explains it in detail.
How to Calculate VAT in Excel
You will need to organise your sales and purchases in different rows and net value, added VAT and gross value in rows. Here is a link to our blogpost that explains it in detail.
What is a reverse VAT calculator and when should you use it?
A reverse VAT calculator (or VAT backwards calculator) extracts the original amount before VAT from a price that already includes VAT. It's useful when you need to:
- Determine how much VAT you've paid on purchases for expense claims
- Separate net amounts from VAT on invoices for accounting purposes
- Set pre-VAT prices based on desired final selling prices
VAT Calculation Formula and Examples
Understanding the different VAT calculation formulas helps ensure accurate tax reporting:
| Calculation | Formula |
|---|---|
| To add VAT to Net Amount | Net × (1 + VAT rate) = Gross |
| To extract VAT from Gross Amount | Gross ÷ (1 + VAT rate) = Net |
| VAT Amount from Net | Net × VAT rate = VAT |
| VAT Amount from Gross | Gross × (VAT rate ÷ (100 + VAT rate)) = VAT |
What is VAT reverse charge?
The VAT reverse charge means the buyer, instead of the seller, is responsible for reporting VAT on a transaction. Normally, the supplier will charge VAT on goods or services sold, however, in this case the seller does not add VAT to the invoice, and the buyer records both the VAT they would have paid and the VAT they can reclaim. This system helps prevent tax fraud and is used in certain industries like construction and electronics and reduces the administrative burden for international suppliers.
