Frequently Asked Questions
How do I calculate a discount?
Multiply the original price by the discount percentage, then divide by 100 to get the saving. Subtract that from the original price to get the final price. Example: 20% off $50 = $50 x 0.20 = $10 off, so you pay $40.
What is 20% off $50?
20% off $50 is $40. The discount is $10 (20% of $50), so the final price is $50 - $10 = $40. You save $10.
How do I find the original price before discount?
If the item costs $40 after a 20% discount, the original price is: $40 / (1 - 0.20) = $40 / 0.80 = $50. The formula is: Original = Sale price / (1 - Discount% / 100).
What is the formula for discount?
Discount amount = Original price x (Discount% / 100). Sale price = Original price - Discount amount. For example: $100 x 0.30 = $30 off, sale price = $70.
How do I calculate percentage savings?
Savings % = ((Original price - Sale price) / Original price) x 100. Example: original $60, sale $45: ((60 - 45) / 60) x 100 = 25% savings.
