How the Discount Calculator Works
Enter the original price and discount rate to see the amount saved and the final sale price. You can also add sales tax after the discount for a realistic checkout estimate.
Formula
Discount = original price x discount rate / 100. Sale price = original price - discount. Final total = sale price x (1 + tax rate / 100).
Example
A $200 item with a 15% discount saves $30 and costs $170 before tax. With 8% sales tax, the final total is $183.60.
Limitations
Stores may apply coupons, fees, shipping and tax in a different order. Check the checkout total before purchasing.
