Formula
How reverse tax calculation works
Start with the tax-inclusive total, then divide by 1 plus the tax rate. Use the tax rate as a decimal in the formula.
Pre-tax Price = Total Price / (1 + Tax Rate)
Tax Amount = Total Price - Pre-tax Price
Example
$100.00 with 7.25% California sales tax
- Tax multiplier = 1.0725
- Pre-tax price = 100 / 1.0725 = 93.24
- Estimated sales tax = 6.76
