Effective discount = (Original − Final) / Original × 100
Example
$200 with 20% then 10%: $200×0.80 = $160. $160×0.90 = $144. Effective: 28%.
Step-by-step calculation
- First discount: $200 × 0.80 = $160.
- Second discount: $160 × 0.90 = $144.
- Effective discount: ($200−$144) ÷ $200 = 28%.
Real-world uses
- Stacking coupon and sale discounts.
- Evaluating promotional campaigns.

Common mistakes
- Assuming two 10% discounts equal 20% off (they equal 19%).
- Adding discounts instead of multiplying.
- Not comparing the final price across different discount combinations.
Frequently asked questions
Why isn't 20% + 10% equal to 30% off?
Discounts multiply. 20% off leaves 80%, then 10% off that leaves 90%. 0.80 × 0.90 = 0.72, which is 28% total.
Which order should I apply discounts?
The result is the same regardless of order because multiplication is commutative.
How do I find the single equivalent discount?
Effective = 1 − (1−d1)(1−d2). For 20% and 10%: 1 − 0.80×0.90 = 28%.
