Instead of manually working through formulas every time, many people use a vat calculator ireland to get instant and accurate results.
What Is Gross Amount?
The gross amount is the final price after VAT has been added.
Example:
- Net Price: €100
- VAT (23%): €23
- Gross Amount: €123
If you only know the €123 total, you can work backwards to find both the net price and the VAT.
Formula to Calculate VAT from Gross Amount
Use this formula:
VAT = Gross Amount × VAT Rate ÷ (100 + VAT Rate)
Or calculate the net amount first:
Net Amount = Gross Amount ÷ (1 + VAT Rate ÷ 100)
Then:
VAT = Gross Amount − Net Amount
Example (23% VAT)
Suppose your invoice total is €246, including 23% VAT.
Step 1: Calculate the Net Amount
€246 ÷ 1.23 = €200
Step 2: Calculate VAT
€246 − €200 = €46 VAT
So:
- Gross Amount: €246
- Net Amount: €200
- VAT: €46
Common Irish VAT Rates

Always use the correct VAT rate when calculating from the gross amount.
