Extract the pre-tax base amount and GST component from an all-inclusive price.
Extract the original price and tax component from any tax-inclusive amount with this free tool.
A tax inclusive price is a quoted price that already contains the tax. When you pay 1180 rupees for a service that has an 18% tax built in, the actual service cost is 1000 rupees and the tax is 180 rupees. The total price is tax-inclusive.
This calculator works backwards from an inclusive price to tell you both figures.
Enter the total tax-inclusive price and the tax rate. The calculator divides the inclusive amount using the standard formula to show the base price before tax and the exact tax amount.
The formula is: base price equals inclusive price divided by (1 plus the tax rate as a decimal). For 18% tax: base = inclusive divided by 1.18.
Use it when you receive a bill showing a total that includes tax but does not break down the base and tax separately. It is also useful for expense reporting, splitting costs between tax-deductible and non-deductible amounts, and auditing supplier invoices.
It works for any tax type: GST, VAT, sales tax, or custom rates.
Retail shops, restaurants, hotels, and many service providers quote inclusive prices. When you record these expenses in your accounts, you need to separate the base cost from the tax.
For businesses claiming input tax credit, this separation is mandatory. You claim the tax portion separately, not the full inclusive price.
Tax inclusive prices include the tax. Tax exclusive prices are base prices to which tax is then added. This calculator handles the inclusive case. Use the GST exclusive calculator on Tez Invoice to add tax to a base price.
Always confirm with a supplier whether their quoted prices are inclusive or exclusive of tax to avoid billing confusion.
