The VAT Formula, Explained
Adding VAT to a price always follows the same two-step formula. Once you understand it, you can work out any VAT-inclusive price by hand, or simply use the calculator above to skip the arithmetic.
Gross Price = Net Price + VAT Amount
Here’s how that looks with real numbers, across a few different currencies and rates:
Example 1
£100 net + 20% VAT
£100 + £20 = £120 gross
Example 2
£250 net + 5% VAT
£250 + £12.50 = £262.50 gross
Example 3
€500 net + 21% VAT
€500 + €105 = €605 gross

When Should You Add VAT?
Adding VAT comes up constantly in day-to-day business admin. Common situations include:
- Invoices — showing the VAT-inclusive total a client owes.
- Quotes — giving a customer a realistic, all-in price upfront.
- Retail pricing — setting shelf or online prices that include VAT.
- Online stores — displaying VAT-inclusive checkout totals.
- Freelancing — adding VAT to project fees once VAT-registered.
- Construction — pricing materials and labour with VAT included.
- Consultancy — issuing VAT-inclusive fee proposals.
- Accounting — checking figures when reconciling sales records.
Common Mistakes When Adding VAT
- Using the incorrect VAT rate — applying the wrong percentage for the country, product or service category.
- Adding VAT twice — recalculating VAT on a price that is already VAT-inclusive.
- Confusing gross and net prices — quoting a net figure where a gross one was expected, or vice versa.
- Incorrect rounding — rounding mid-calculation instead of on the final figure, which can create small but noticeable errors.
- Wrong VAT category — treating a reduced-rate or zero-rated item as if it were standard-rated.
