Calculate the original price before tax was applied
The Reverse Sales Tax Calculator is a handy financial tool that helps you determine the original price of a product or service before tax was applied. When you receive an invoice or see a price that includes tax, it can be difficult to understand exactly how much you’re paying for the product itself and how much of that total is going to the government as tax. This calculator simplifies that by reversing the tax-inclusive amount and showing you the pre-tax price and the tax portion.

The Reverse Sales Tax Calculator uses a straightforward formula:
Price before tax = Price with tax ÷ (1 + (Tax rate ÷ 100))
For example, if the total amount is ₹1300 and the tax rate is 12%, the calculator will divide ₹1300 by 1.12 to give you the price before tax: ₹1160.71. It will then subtract this value from ₹1300 to calculate the tax amount: ₹139.29. This breakdown gives you complete clarity on how the price was formed and how much was paid as tax.
| Total Price (₹) | Tax Rate (%) | Price Before Tax (₹) | Tax Amount (₹) |
|---|---|---|---|
| 1300.00 | 12 | 1160.71 | 139.29 |
| 1120.00 | 18 | 949.15 | 170.85 |
| 750.00 | 5 | 714.29 | 35.71 |
| 999.00 | 28 | 780.47 | 218.53 |
| 15000.00 | 12 | 13392.86 | 1607.14 |
