About this tool
Australia charges 10% GST, so the GST inside a GST-inclusive price is one eleventh of it. New Zealand charges 15%, so the GST inside a price is 3/23 of it. Singapore charges 9%.
Canada combines a 5% federal GST with provincial tax. Ontario, Nova Scotia (14% since 1 April 2025), New Brunswick, Newfoundland and Labrador and Prince Edward Island use a single harmonized sales tax (HST). British Columbia, Saskatchewan and Manitoba add a separate provincial sales tax, Quebec adds QST, and Alberta and the territories charge GST only. The calculator shows the federal and provincial parts separately.
India uses several GST slabs. The calculator applies 18%, the most common rate for services; choose the VAT calculator with a custom rate for other slabs.
