GST stands for Goods and Services Tax — an indirect tax levied on the supply of goods and services. In India it replaced multiple indirect taxes from July 2017. Australia uses a flat 10% GST, while Canada applies GST/HST at varying rates by province. See also our Marginal Tax Rate Calculator.
To add GST to a net price, multiply the amount by the GST rate and add it to the original. For example, with a 10% rate: GST Amount = Amount × 0.10, and Total = Amount + GST Amount. Our calculator does this automatically when you select 'Exclusive'.
To find the GST component in a GST-inclusive price, divide the total amount by (1 + GST rate). For example, at 10%: Net Amount = Total ÷ 1.10, and GST Amount = Total − Net Amount. Select 'Inclusive' in the calculator to do this automatically.
India has four main GST slabs: 5%, 12%, 18%, and 28%. Essential goods like food items may attract 0% GST, while luxury items and sin goods fall under the 28% bracket. There are also additional cess charges on some items in the highest slab.
Australia applies a flat GST rate of 10% on most goods and services. Some items are GST-free (0%), such as basic foods, medical supplies, and certain educational courses. To find the GST component in a price, simply divide the total by 11.
In Canada, the federal GST rate is 5%. Some provinces have harmonized their provincial sales tax with the federal GST to create the Harmonized Sales Tax (HST), which ranges from 13% to 15% depending on the province. Other provinces charge GST plus a separate Provincial Sales Tax (PST).
A GST-exclusive price does not include tax — GST is added on top when you check out. A GST-inclusive price already has the tax built in. Businesses typically quote GST-exclusive prices to other businesses and GST-inclusive prices to end consumers.
Yes. While called a GST calculator, the math is identical to VAT calculations. Simply enter your amount and the applicable tax rate (e.g. 20% for UK VAT, 10% for Australian GST, 18% for Indian GST) and choose inclusive or exclusive to get an accurate result.
