Understand the method, inputs and limits behind your result.
- Formula
- Tax-exclusive: tax = price × rate / 100; total = price + tax. Tax-inclusive: pretax price = total / (1 + rate/100); tax = total − pretax price.
- Variables
- I have the price: Before tax, Including tax
- Price
- Tax rate. e.g. 17% GST in Pakistan, 18% GST in India, 5% VAT in the UAE, or your US state and local rate.
- Units
- Tax rate: %
- Use the same selected currency for all monetary inputs. Changing the symbol does not convert exchange rates.
- Example
- Adding 17% GST to 100 gives a tax of 17 and a total of 117. Removing 17% from a total of 117 gives back the original price of 100.
- Assumptions
- Tax rules differ by country, region and product type. Check the rate that applies to your sale.

Methodology & References
The method depends on the selected model and input options. Review the assumptions and references above before interpreting the result.
- Choose whether your price is before tax or already includes tax.
- Enter the price and the tax rate.
- Read the tax amount, the price before tax and the total with tax.
Interpretation and limitations
- How do I remove tax from a price? Divide the total by 1 plus the tax rate as a decimal. For 17% tax, 117 ÷ 1.17 = 100. Subtracting 17% of 117 would give the wrong answer.
- Is VAT the same as sales tax? Both are taxes on sales, but VAT is collected at each stage of the supply chain while US sales tax is charged only at the final sale. The math for a single price is the same.
- Why do tax rates vary? Rates depend on the country, state or province and sometimes the type of product. Some items are exempt or taxed at a reduced rate.
