Key takeaway
VAT (value-added tax) is a consumption tax added to many prices. Tools help you move between VAT-exclusive and VAT-inclusive amounts when you know the rate.
Rules vary by country — this is arithmetic help, not tax advice.
What it means
Exclusive amount is before VAT; inclusive is after VAT.
Rate is a percent such as 20%.
Businesses often reclaim input VAT under local rules — your accountant owns that.
When you would use it
Quoting clients, checking invoices, converting shelf prices.
Not a substitute for filing software or a tax professional.
How to use the tool
Use the matching TCB Tools page and work top to bottom:
- Open the VAT Calculator.
- Enter amount and rate.
- Choose whether the amount already includes VAT if the UI asks.
- Read net, VAT and gross.
No account is required. Results update as you type.
Formula / method + worked example
VAT = net × rate. Gross = net × (1+rate).
If gross is known: net = gross ÷ (1+rate).
Example: net 100 at 20% → VAT 20, gross 120.
How to read the result
Confirm whether your figure is already gross.
Multi-rate catalogs need line-level care.
Not legal/tax advice.
Common mistakes
- Applying VAT twice. Check inclusive vs exclusive.
- Wrong rate for the region. Verify.
- Mixing currencies mid-calc. Convert first.
- Ignoring exemptions. Ask finance.
