VAT Calculator Saudi Arabia

Extract or add 15% Saudi VAT using the 3/23 reverse fraction, with line discounts, the legacy 5% rate and ZATCA thresholds.

This calculator splits Saudi VAT out of a tax-inclusive riyal price and adds it to a net price, using the standard 15% rate that has applied since 1 July 2020. Reverse extraction uses the fraction 15/115, which simplifies to 3/23, so an SAR 1,150 invoice contains exactly SAR 150 of VAT on an SAR 1,000 taxable amount. Line discounts, the legacy 5% rate for invoices dated between January 2018 and June 2020, and the ZATCA registration thresholds are all built in.

Why use VAT Calculator Saudi Arabia

• Correct reverse fraction

  Uses 3/23 rather than the common mistake of subtracting 15% from the gross figure.

• Discount before tax

  Applies the line discount first, so the taxable amount matches what a compliant tax invoice must show.

• Both rate eras

  Handles the 15% current rate and the 5% rate that applied until 30 June 2020.

Common use cases

• A Riyadh retail receipt shows only the SAR 2,300 total and you need the taxable amount and VAT for your accounts.
• Issuing a tax invoice where a 10% trade discount must be applied before VAT is calculated on the discounted line.
• Recalculating a credit note against an invoice issued in 2019, when the Saudi rate was still 5%.
