Sales Tax Calculator

Even though GST replaced most sales tax in India, several states still levy sales tax on specific items like petrol, diesel, alcohol and lottery tickets, and small businesses outside the GST regime sometimes quote prices without tax. This calculator adds or extracts a sales tax percentage from any amount, which is handy when you are reconciling a fuel bill, pricing goods for a state that still applies sales tax, or checking whether a quoted price already includes tax. The same math applies to US-style sales tax, so expats and students comparing prices across countries can use it too. Choose add-tax or remove-tax mode depending on whether the amount you have is before or after tax. Businesses that quote prices excluding tax also use it to print the correct GST-inclusive bill total at checkout. The remove-tax mode is the one to use when a dealer quotes a price that already includes tax and you need the pre-tax value for your records. The same reverse calculation also appears on e-commerce invoices where the tax-inclusive total is shown and the net value must be reported.
