What Is GST?

GST stands for Goods and Services Tax. It is the tax added to the price of most goods and services. In Pakistan the standard sales tax rate is 18%, in India GST rates are 5%, 12%, 18% and 28% depending on the item, and in Bangladesh VAT is usually 15%. Shopkeepers either show you a price that already includes GST, or they add GST at the bill. This calculator handles both cases.

When the price is without GST, the tax is simply price multiplied by the rate divided by 100. When the price already includes GST, you must divide the price by one plus the rate to find the original price, and the difference is the GST part. Many people get this second case wrong and overpay in their own estimates, so always check which type of price you have.

Small businesses use this calculator every day to make invoices, check bills from suppliers, and file their tax returns. Students and shopkeepers in Pakistan, India and Bangladesh can use it with their own currency — just enter the numbers and the maths stays the same. Keep the rate correct for your country and item, because the wrong rate gives a wrong answer.
