How to Calculate a Discount
Divide the discount percentage by 100.
20% → 0.20
Multiply the original price by the decimal.
Savings = Original Price × Discount Rate
Subtract the savings from the original price.
Final Price = Original Price − Savings
Final Price = Price × (1 − Discount% ÷ 100)
Worked Examples
A jacket originally priced at 12,000 is 30% off.
12,000 × (1 − 0.30) = 8,400 — save 3,600
A laptop originally at 980 is 15% off.
980 × (1 − 0.15) = 833 — save 147
A 45 meal with a 10% coupon.
45 × (1 − 0.10) = 40.50 — save 4.50
A 250 item at 40% off.
250 × (1 − 0.40) = 150 — save 100
Frequently Asked Questions
How do I apply two discounts in a row?
Apply each discount sequentially. For example, 20% off then 10% off on a 1000 item: 1000 × 0.80 = 800, then 800 × 0.90 = 720. Note: this is not the same as 30% off.
Is 50% off the same as buy-one-get-one-free?
Only if you buy exactly two items. 50% off applies to one item, while BOGO requires purchasing two.
What if the discount is over 100%?
A discount over 100% would mean the store pays you, which is not realistic. The calculator shows a validation message for this case.
How do I find the original price from the sale price?
Use the Reverse Percentage Calculator. Divide the final price by (1 − discount/100) to find the original.
