Frequently Asked Questions

How do I calculate a discount?
Multiply the original price by the discount percentage divided by 100. For example, 20% off $50: $50 × 0.20 = $10 savings, final price = $40.
Can I include sales tax?
Yes. Enter your local sales tax rate in the optional tax field. The calculator applies the discount first, then adds tax to the discounted price.
How do I compare two discounts?
Enter your price, try different discount percentages using the preset buttons, and compare the final prices to find the best deal.
