How it works: Thai VAT 7%

Add VAT: total = price before VAT × 1.07. Remove VAT: price before VAT = total ÷ 1.07, and VAT = total − price before VAT.

Results are rounded to 2 decimals. The amount is also written in Thai words, ready to paste into a Thai quotation or receipt.

FAQ

How do I remove 7% VAT from a price?

Divide the total by 1.07. For example 1,070 ÷ 1.07 = 1,000 baht, so the VAT is 70 baht.

Why not just take 7% of the total?

VAT is already inside the total, so 7% of the total would overstate it.
