What Is VAT?

- The UK has a standard VAT rate (with reduced rates for some goods)
- Some European countries have multiple VAT categories
Understanding how to calculate VAT manually helps you:
- Check VAT charges are correct
- Calculate VAT amount from the total amount
- Determine VAT exclusive and VAT inclusive prices and what are these terms
- Estimate VAT refund on different types of goods
- Calculate VAT and duty on imports
How to Calculate VAT Manually (Basic Formula)
The basic formula for calculating VAT is given below:
If Price is VAT Exclusive (VAT not included)
VAT Amount = (Net Price × VAT Rate) ÷ 100
Total Price (VAT Inclusive) = Net Price + VAT Amount
Example (15% VAT)
Let’s say the net price of a product is $100 and VAT is 15%.
VAT = (100 × 15) ÷ 100
VAT = 15
Total Price = 100 + 15 = 115
So:
- VAT amount = 15
- VAT inclusive price = 115
How to Calculate VAT Manually from a VAT Inclusive Price
Sometimes you only know the total price (VAT inclusive) and need to find the VAT amount inside it.
Formula:
VAT Amount = (Total Price × VAT Rate) ÷ (100 + VAT Rate)
Net Price = Total Price − VAT Amount
Example (15% VAT)
Total Price = 115
VAT Rate = 15%
VAT = (115 × 15) ÷ 115
VAT = 15
Net Price = 115 − 15 = 100
This method is very useful when calculating the VAT amount from the total amount.
How to Calculate VAT 15% Manually
Since many countries use 15% VAT, so fast way to find 15% VAT is:
Quick Method for 15% VAT:
Multiply by 0.15 to find VAT
Multiply by 1.15 to find total price
Example:
Net Price = 200
VAT = 200 × 0.15 = 30
Total = 200 × 1.15 = 230
This is the fastest way to calculate VAT 15% without a calculator.
VAT Inclusive vs VAT Exclusive: What is the Difference?
Understanding VAT inclusive and VAT exclusive pricing is very important.
VAT Exclusive Price
- Its mean that the VAT is NOT included in the Price
- You must add VAT to get total
- Common in wholesale or business invoices
VAT Inclusive Price
- Its mean that the VAT is already included
- Final price for consumers
- Common in retail stores
If you’re learning how to calculate VAT manually, always first check whether the amount is inclusive or exclusive.
How to Calculate VAT Amount from Total
Many people search for how to calculate VAT amount from total when they only have a receipt.
This is the general formula to calculate VAT
VAT = (Total × VAT Rate) ÷ (100 + VAT Rate)
Example (20% VAT)
Total = 240
VAT Rate = 20%
VAT = (240 × 20) ÷ 120
VAT = 40
Net Price = 240 − 40 = 200
Now you know exactly how much VAT was included.
How to Calculate VAT UK
The VAT Rate in UK is Given below
- Standard rate
- Reduced rate
- Zero rate
To calculate VAT UK manually, use the same formula:
VAT = Net Price × VAT Rate ÷ 100
Example (Standard rate example):
Net Price = £500
VAT = 500 × 20% = 100
Total = 600
Even though VAT UK has multiple categories, the calculation method remains the same.
How to Calculate VAT Charges for Businesses
Businesses need to calculate VAT charges accurately for invoices.
Steps:
- Determine VAT rate
- Multiply net amount by VAT rate
- Add VAT to get total
- Show VAT amount clearly on invoice
Example:
Service fee = 1,000
VAT rate = 15%
VAT = 150
Total invoice = 1,150
Proper VAT Calculation is so much help full in businesses.
How to Calculate VAT Refund
A VAT refund happens when:
- Businesses paid more VAT than they collected
- Tourists claim VAT refund on purchases
- Exported goods are zero-rated
Business VAT Refund Formula:
VAT Refund = Input VAT − Output VAT
Example:
Input VAT paid = 500
Output VAT collected = 350
Refund = 150
Understanding how to calculate VAT manually helps you determine your VAT tax refund correctly.
How to Calculate VAT Refund in France
France offers VAT refund for tourists on eligible purchases.
Steps:
- Check VAT amount on receipt
- Identify VAT rate applied
- Calculate VAT portion using inclusive formula
If total price is €120 (including 20% VAT):
VAT = (120 × 20) ÷ 120
VAT = 20
Tourist may claim that €20 (minus service fee).
This is how to calculate VAT refund in France manually.
