🎯 Double Discount Calculator
Calculate final price after two discounts
How to Use This Calculator
Enter Original Price
Input the original price of the item before any discounts.
Enter First and Second Discount
Enter the first discount percentage (e.g., 20 for 20% off), then the second discount percentage (e.g., 15 for 15% off). The second discount is applied to the price after the first discount.
Review Final Price
See the final price after both discounts, total savings, and the equivalent single discount percentage. Use this to understand the true value of stacked discounts.
Formula
After First Discount = Original Price × (1 - First Discount%)
Final Price = After First Discount × (1 - Second Discount%)
Total Discount% = (1 - (1 - First Discount%) × (1 - Second Discount%)) × 100
Example Calculation:
If original price $100, first discount 20%, second discount 15%:
• After first discount = $100 × (1 - 20%) = $80
• Final price = $80 × (1 - 15%) = $68
• Total discount = 32% (not 35% - discounts don't add!)
About Double Discount Calculator
A double discount calculator helps you calculate the final price after applying two sequential discounts. When retailers offer multiple discounts (like a store-wide sale plus a coupon, or a discount plus a loyalty program discount), the discounts are applied sequentially, not added together. This calculator shows you the true final price and the equivalent single discount percentage. Understanding how double discounts work helps you make better purchasing decisions and understand the true value of stacked discounts.
When to Use This Calculator
- Stacked Discounts: Calculate final price with multiple discounts
- Coupon + Sale: Combine store discounts with coupon discounts
- Loyalty Programs: Calculate discounts with loyalty program benefits
- Deal Comparison: Compare different discount combinations
Understanding Double Discounts
- Sequential Application: Discounts are applied one after another, not added
- Not Additive: 20% + 15% doesn't equal 35% - it equals 32%
- Order Matters: The order of discounts can affect the final price (if rates differ)
- Equivalent Discount: The total discount is less than the sum of individual discounts

Frequently Asked Questions
Do discounts add together?
No, discounts don't add together - they're applied sequentially. For example, a 20% discount followed by a 15% discount doesn't equal 35% off. Instead, you get 20% off the original price, then 15% off the already discounted price, resulting in about 32% total discount. This calculator correctly calculates sequential discounts and shows you the equivalent single discount percentage.
How are double discounts calculated?
Double discounts are calculated by applying the first discount to the original price, then applying the second discount to the already discounted price. For example, with a $100 item, 20% off, then 15% off: First discount: $100 × 80% = $80. Second discount: $80 × 85% = $68. Total discount: $32 (32%), not $35 (35%). The formula is: Final Price = Original Price × (1 - Discount1%) × (1 - Discount2%).
What's the difference between adding discounts and applying them sequentially?
Adding discounts (20% + 15% = 35%) would give you a larger discount than sequential application (20% then 15% = 32%). Sequential application is how retailers actually apply multiple discounts - each discount is applied to the already discounted price, not the original price. This calculator shows you the correct sequential calculation, which results in a smaller total discount than simply adding the percentages.
Can I use this for more than two discounts?
This calculator is designed for two discounts, but you can use it multiple times by entering the result from the first calculation as the "original price" for the next discount. However, for three or more discounts, it's easier to use the formula: Final Price = Original Price × (1 - D1%) × (1 - D2%) × (1 - D3%)... where D1, D2, D3 are the discount percentages applied sequentially.
