- It does not know your local tax rules or rounding rules.
- Shown amounts are rounded to cents for display.
Frequently asked questions
Is the tax added before or after the discount?
After. The discount lowers the price first and the tax is worked out on the lower price. Rules differ by place, so check your receipt for the real figure.
How do I find the original price from a sale price?
Divide the sale price by one minus the discount as a decimal. For 25% off, divide by 0.75.
Does it round to cents?
Amounts are shown to two decimal places. The tool does not know about coupons or store rounding rules.
