Add or remove GST (sales tax) from any amount.
🛠️ Free tool by the NayaPakistan team · Updated November 2026
Work out GST (General Sales Tax) either way: add it to a net price to get the total a customer pays, or pull the GST out of a tax-inclusive amount to find the net and the tax portion. The standard rate in Pakistan is 18%, but you can enter any rate.
It's handy for invoices, quotations and checking receipts. For pricing and profit, pair it with the Profit Margin and Discount calculators.
Multiply the net price by 1.18 (or enter it here with mode "Add GST"). For example, Rs. 1,000 + 18% GST = Rs. 1,180.
Divide the GST-inclusive amount by 1.18 to get the net, and the difference is the GST. This tool does it in "Remove GST" mode.
The standard sales-tax rate is 18%, though some goods and services have different rates. Enter the applicable rate in the calculator.
