Formula • Worked example • Interpretation
Calculate sale prices and savings
A discount reduces an original price by a percentage or fixed amount. Sales tax, if applicable, may then be added according to local rules.
Calculation method
Worked example
An $80 item with a 25% discount saves $20 and costs $60 before any sales tax.
What your result means
Two consecutive discounts of 20% and 10% equal a 28% total reduction, not 30%, because the second percentage applies to the already discounted price.
Tips for better calculations
Use the final price—including tax and delivery—to compare competing promotions.
Assumptions and limitations
Sales-tax rules and which amount is taxable depend on location and promotion type. Shipping costs and coupon restrictions are not included.
