About this calculator
Add VAT to a net price, or remove it from a gross price.
How it’s calculated
Gross = net × 1.15. Net = gross ÷ 1.15. Don’t just subtract 15% from the gross figure: the VAT inside a VAT-inclusive price is the total × 15 ÷ 115, not 15% of the total.

Tips from the trade
- VAT is 15%. You must register with SARS once your taxable sales pass R2.3 million in 12 months. Until then, charge no VAT; once registered, invoices must say “Tax Invoice” and show your VAT number.
