How India GST works
India charges 18.00% GST on most goods and services. 18% is the standard GST slab; 5%, 12% and 28% apply to other categories.
GST is added to the net price to give the gross price the customer pays. To work backwards from a gross price, you divide by 1.18 to find the net amount.
Businesses generally collect GST on sales and reclaim it on purchases, so it is ultimately borne by the end consumer.
Adding vs removing GST
Use "add" when you have a net (tax-exclusive) price and want the final price. Use "remove" when you have a gross (tax-inclusive) price and need the net amount — useful for invoices and expense claims.
This calculator does both and shows the GST amount separately so you can record it correctly.
What is taxed
Most goods and services carry the standard rate, but many countries apply reduced or zero rates to essentials such as food, books or children's items.
This is a planning estimate at the standard 18.00% rate. Confirm the correct rate for your product with the Income Tax Department (incometax.gov.in).
