Discount Calculator

To calculate a percentage discount, multiply the original price by the discount rate (expressed as a decimal). For example, a 20% discount on a $100 item equals $100 × 0.20 = $20 saved. Subtract that from the original price to get the final sale price of $80.

The formula is: Sale Price = Original Price × (1 − Discount% / 100). So for a 25% discount on $200, the sale price is $200 × 0.75 = $150. You can also express it as: Sale Price = Original Price − (Original Price × Discount Rate).

Rearrange the formula: Original Price = Sale Price / (1 − Discount% / 100). For example, if the sale price is $75 after a 25% discount, the original price is $75 / 0.75 = $100.

A percent-off discount (e.g., 30% off) reduces the price by a proportion of the original price, so the saving amount varies with the price. A fixed-amount discount (e.g., $20 off) subtracts a set dollar value regardless of the original price. Percent-off discounts are more beneficial for higher-priced items.

Amount Saved = Original Price × (Discount% / 100). For instance, a 15% discount on a $60 product saves you $60 × 0.15 = $9, making the final price $51.

Yes. Discount% = ((Original Price − Sale Price) / Original Price) × 100. If an item went from $80 to $60, the discount is ((80 − 60) / 80) × 100 = 25%.

For stacked discounts, apply each discount sequentially rather than adding them. For a 20% then 10% discount on $100: after the first discount you get $80, then 10% off $80 gives $72 — not $70 as you'd get by adding 30%. The combined effective discount is 28%, not 30%.

Not necessarily — the absolute saving depends on both the discount percentage and the original price. A 50% discount on a $10 item saves you $5, while a 10% discount on a $200 item saves you $20. Always compare the actual dollar saving alongside the percentage.
