Calculate the final price after discount, the amount you save, and the discount percentage. Perfect for shopping, comparing sales, or determining the original price when you know the sale price and discount percentage.
A discount is a reduction in the original price of a product or service. Discounts are typically expressed as a percentage off the original price (e.g., "20% off") or as a fixed amount (e.g., "$10 off"). Understanding how discounts work helps you make informed purchasing decisions and compare deals effectively.
| Discount % | Savings ($) | Final Price ($) | Discount % | Savings ($) | Final Price ($) |
|---|---|---|---|---|---|
| 5% | $5.00 | $95.00 | 30% | $30.00 | $70.00 |
| 10% | $10.00 | $90.00 | 35% | $35.00 | $65.00 |
| 15% | $15.00 | $85.00 | 40% | $40.00 | $60.00 |
| 20% | $20.00 | $80.00 | 50% | $50.00 | $50.00 |
| 25% | $25.00 | $75.00 | 60% | $60.00 | $40.00 |
How do I calculate a 20% discount?
Multiply the original price by 0.20 to find the savings, then subtract from the original price. Example: $50 × 0.20 = $10 savings; $50 - $10 = $40 final price. Or simply multiply by 0.80: $50 × 0.80 = $40.
What does "buy one get one 50% off" mean?
You pay full price for the first item and 50% off the second. For two $50 items: $50 + $25 = $75 total, which is equivalent to 25% off both items combined.
Is a higher discount always better?
Not necessarily. A 50% discount on an inflated price might be worse than 20% off a fairly priced item. Always compare final prices, not discount percentages alone.
How do I calculate the original price after a discount?
Divide the sale price by (1 - discount percentage ÷ 100). Example: $80 sale price with 20% discount: $80 ÷ 0.80 = $100 original price.
What's the difference between discount and markup?
Discount reduces the price from original to sale price. Markup increases cost to selling price. A 25% discount requires a 33.3% markup to return to original price.
💡 Smart Shopping Tip: When comparing deals, calculate the final price per unit or the total savings percentage. A "20% off" coupon applied to an already 30% off item equals 44% off (not 50% off), because discounts apply sequentially, not additively.
💰 Additional Savings: Don't forget to factor in sales tax (where applicable) and shipping costs when comparing final prices. A higher discount might still result in a higher out-of-pocket cost if shipping is expensive.
