VAT Calculator is a narrow tool on purpose
Calculate VAT-exclusive, VAT amount and VAT-inclusive totals using a custom rate.
Adding tax and extracting tax are different calculations
When an amount already includes tax, you can’t recover the tax portion by simply multiplying the gross total by the rate. The inclusive calculation works backwards from the tax-inclusive amount.
Tax rules, exemptions and rounding can vary by jurisdiction. The arithmetic is useful; it isn't tax advice.
Where VAT Calculator fits cleanly
Use it when you need to check invoices and quotations; it also fits when you need to extract tax from VAT-inclusive prices. If the job asks for more than that, split the workflow rather than making one tool do two different things.
Don’t ask VAT Calculator to do a different job
Tax treatment, exemptions and applicable rates depend on the jurisdiction and transaction. Use this for arithmetic, not tax advice.
