How Is Discount Calculated?
A percentage discount means reducing the original price by a certain fraction. The formula is straightforward:
Sale Price = Original Price × (1 − Discount% ÷ 100)
Savings = Original Price − Sale Price
Frequently Asked Questions
How do I calculate 30% off $80?
30% of $80 = $24 discount. Sale price = $80 − $24 = $56. Or use the formula: $80 × (1 − 0.30) = $56.
What does "double discount" mean?
A double discount means applying two discounts sequentially. For example, 20% off then 10% off is NOT 30% off — it's 20% first, then 10% off the reduced price, equaling 28% total savings.
How do I find the original price from a discounted price?
Use the reverse calculator above, or the formula: Original = Sale Price ÷ (1 − Discount% ÷ 100).
