Method and assumptions
This arithmetic tool does not determine whether VAT applies, the correct jurisdiction, registration duty or recoverability. Enter the rate and price treatment from your tax records.
Exclusive mode: VAT = net × rate. Inclusive mode: net = gross / (1 + rate), and VAT = gross - net.
Worked scenario
Use exclusive mode to add a confirmed VAT rate to a net price, and inclusive mode to split a tax-inclusive receipt into net amount and VAT. Compare both modes using the same rate to understand why VAT is not calculated by simply multiplying the gross amount by the rate.
How to interpret the result
This is an arithmetic tool, not a tax determination. Jurisdiction, place of supply, registration, exemptions, marketplace collection, invoice rules and input-tax recovery require current records or professional advice. Keep recoverable VAT out of permanent margin cost while modeling its cash timing when material.

Common mistakes
- Multiplying a VAT-inclusive amount by the rate to find included tax.
- Using a rate without confirming jurisdiction and product treatment.
- Treating recoverable VAT as a permanent expense.
Before using the result
- Confirm whether the entered price is net or gross.
- Use the rate supported by the transaction record.
- Reconcile the result with invoice and tax reporting treatment.
Questions to check before deciding
Does this determine the correct VAT rate?
No. Rates and obligations depend on jurisdiction, product and seller status.
Why is VAT not 20% of an inclusive price?
A 20% rate is applied to the net amount, so VAT is one-sixth of a price that already includes 20% VAT.
