Enter your original price and percent off to find the final price and exactly how much you save. You can also apply a stackable additional discount — a second coupon or deal applied on top of the first — to see your true total savings.

To find the discount amount, multiply the original price by the percentage divided by 100. Then subtract that result from the original price to get the final price. For example, 20% off $279 means 0.20 × $279 = $55.80 saved, and a final price of $223.20.
A stackable discount is a second percentage off that is applied to the already-discounted price — not the original price. For example, if an item is $223.20 after a 20% discount and you have a 15% coupon, the 15% applies to $223.20, not the original $279. This means you save less than a combined 35% off the original.
No. When discounts are stacked, the second discount applies to the reduced price after the first discount. So 20% then 15% off gives you an effective total discount of about 32%, not 35%. The order you apply them does not affect the final price.
Multiply the original price by (1 − percent off / 100). For example, 20% off $279 = $279 × 0.80 = $223.20. This gives you the final price directly without needing to calculate the savings separately.
Yes. Divide the amount saved (original price minus final price) by the original price, then multiply by 100 to get the percentage. For example, if an item originally cost $279 and now costs $223.20, the discount is ($55.80 / $279) × 100 = 20%.
No. Applying a 20% discount followed by a 15% discount gives the same final price as applying 15% first and then 20%. The math is commutative, so the order does not change your total savings or final price.
The effective total discount for two stacked percentages (A% and B%) is calculated as: Total % off = 1 − (1 − A/100) × (1 − B/100), then multiplied by 100. For example, 20% and 15% stacked gives 1 − 0.80 × 0.85 = 1 − 0.68 = 32% effective total discount.
They are essentially the same concept. Percent off describes a discount applied to a retail price, while percent decrease is a general mathematical term for how much a value has reduced relative to its original amount. Both are calculated the same way: (change / original) × 100.
