Frequently Asked Questions
How do I calculate a discount?
Multiply the price by the discount percentage and divide by 100 to get the savings, then subtract it. 25% off 80 = 80 × 25 ÷ 100 = 20 off, so you pay 60.
Is 20% off plus an extra 10% off the same as 30% off?
No. The extra 10% applies to the already reduced price, so together they give 28% off, not 30%. The calculator shows the real combined discount.
Is tax added before or after the discount?
Usually after: you pay tax on the discounted price. That is how this calculator works.
How do I find the original price from a sale price?
Divide the sale price by (1 − discount ÷ 100). A 60 sale price at 25% off was 60 ÷ 0.75 = 80.
