Find the sale price and savings from a discount, with optional estimated tax.
Price after discount$80.00

Estimated total with tax$80.00No sales tax added
Tax is estimated on the discounted price. Actual tax treatment and rounding depend on the seller and location.
How to calculate a sale price
Multiply the original price by the discount percentage to find the amount saved, then subtract that amount from the original price. For example, a 20% discount on 100 saves 20 and leaves a discounted price of 80, before any sales tax.
Optional estimated sales tax
If you enter a tax rate, this tool estimates tax on the discounted price. Tax rules, product exemptions, and rounding differ by seller and location, so check the final checkout total.
