Frequently Asked Questions
How do I calculate a percentage discount on a price?
Multiply the original price by the discount percentage divided by 100, then subtract from the original price. For example, 25% off $80: discount = $80 × 0.25 = $20, final price = $80 - $20 = $60. Our calculator does this instantly.
How do double discounts work?
The second discount applies to the already-reduced price, not the original. So 30% off + 20% off is NOT 50% off. Our calculator correctly applies sequential discounts and shows the true total savings percentage.
How do I find the original price before a discount?
Use the formula: Original Price = Sale Price / (1 - Discount%). For example, if an item costs $60 after 25% off: $60 / 0.75 = $80 original price. Enter the sale price and discount in our reverse calculator.
