How to Calculate Discounts
A discount reduces the original price of a product or service. Whether shopping online, at a store, or applying a coupon code, the math behind a discount is always the same. There are three common discount scenarios:
Mode 1
Percentage Discount
What is the final price after 20% off $200?
Formula
Discount Amount = Original × (Discount% ÷ 100)
Final Price = Original − Discount AmountExample
Discount = $200 × 0.20 = $40
Final = $200 − $40 = $160Mode 2
Fixed Amount Discount
What is the final price after $30 off $150?
Formula
Final Price = Original Price − Discount Amount
Discount % = (Discount Amount ÷ Original) × 100Example
Final = $150 − $30 = $120
Discount% = (30 ÷ 150) × 100 = 20%Mode 3
Reverse Discount (Find Original Price)
An item costs $80 after a 20% discount. What was the original price?
Formula
Original Price = Sale Price ÷ (1 − Discount% ÷ 100)Example
Original = $80 ÷ (1 − 0.20) = $80 ÷ 0.80 = $100How Percent-Off Sales Work
When a store advertises "30% off," they apply a multiplier to every item's price. The multiplier is (1 − discount rate). So a 30% discount means you pay 70% of the original price.
| Discount | You Pay | On $100 | On $250 |
|---|---|---|---|
| 10% | 90% | $90.00 | $225.00 |
| 15% | 85% | $85.00 | $212.50 |
| 20% | 80% | $80.00 | $200.00 |
| 25% | 75% | $75.00 | $187.50 |
| 30% | 70% | $70.00 | $175.00 |
| 40% | 60% | $60.00 | $150.00 |
| 50% | 50% | $50.00 | $125.00 |
Markdown vs Discount — What's the Difference?
🏷️ Markdown
A permanent reduction in a product's listed retail price. Used to clear out inventory, end-of-season items, or discontinue a product. The reduced price becomes the new standard price.
Example: Winter coats marked down 40% at the end of the season.
🎟️ Discount
A temporary price reduction via a sale, coupon, promo code, or loyalty reward. The original price is unchanged — the buyer simply pays less for that specific transaction.
Example: 20% off coupon code valid for one week only.
Key insight: The calculation is identical for both. The formula
Final = Original × (1 − Rate) applies whether it's a permanent markdown or a temporary promotional discount.Real-Life Discount Examples
