FAQ

Frequently Asked Questions

How do you calculate a percentage discount?
Multiply the original price by the discount percentage divided by 100 to find savings. Subtract savings from the original price to get the final price: Final = Price × (1 - Discount/100).
How do double discounts or stacked coupons work?
When discounts stack, the second discount is typically applied to the already reduced price, rather than adding percentages together. A 20% off plus 10% coupon equals 28% total off.
Does sales tax apply before or after discounts?
In most jurisdictions, sales tax is applied to the discounted sale price that you actually pay, rather than the initial sticker price.
Can I calculate the original price from a sale price?
Yes! Use the reverse mode: Original Price = Sale Price / (1 - (Discount % / 100)).
Is this discount calculator free for commercial use?
Yes, completely free for shoppers, retail store owners, and e-commerce sellers without restrictions.
