What Is VAT?
VAT (Value Added Tax) is a consumption tax added to goods and services at each stage of production and distribution. In practical terms, many businesses show prices either:
- Excluding VAT (net price), or
- Including VAT (gross price).
Knowing how to move between net and gross values is essential for invoicing, budgeting, bookkeeping, and price comparisons.
How to Use This Online VAT Calculator
1) Choose a Calculation Type
- Add VAT to Net Amount: Start with a price before tax and calculate final price after VAT.
- Remove VAT from Gross Amount: Start with a VAT-inclusive total and extract the pre-tax amount.
- Calculate Net/Gross from VAT Amount: Start with the VAT amount itself and calculate corresponding net and gross values.
2) Enter Your Amount
The meaning of the amount field changes depending on your selected calculation type. The label updates automatically so you always know what to enter.
3) Enter VAT Rate
Type your local VAT rate (for example, 5%, 10%, 20%, etc.). The calculator supports decimal rates such as 7.5%.
4) Click “Calculate VAT”
You’ll immediately get a clear breakdown of net amount, VAT amount, and gross amount.
VAT Formulas Used
For transparency, here are the formulas behind the calculator:
- Add VAT: VAT = Net × (Rate / 100), Gross = Net + VAT
- Remove VAT: Net = Gross / (1 + Rate / 100), VAT = Gross − Net
- From VAT amount: Net = VAT × 100 / Rate, Gross = Net + VAT
Common Use Cases

For E-commerce Sellers
Use VAT calculations when setting catalog prices, creating VAT-compliant invoices, or planning promotions without hurting margins.
For Bookkeeping and Accounting Prep
Before submitting records to your accountant, verify that your VAT components are accurate and consistent.
