Double Discount Calculator
Shopping sales often feature multiple discounts applied one after another. Understanding how two successive discounts impact the final price can help you make smarter purchase decisions. The Double Discount Calculator simplifies this by calculating the ultimate price you pay after two discounts and showing you the total effective discount.
Formula
To calculate the final price after two successive discounts:
- First, apply the first discount to the original price:
Price after first discount = Original Price × (1 – First Discount ÷ 100) - Then apply the second discount on the new price:
Final Price = Price after first discount × (1 – Second Discount ÷ 100) - The total discount percentage is:
Total Discount % = 100 × (1 – Final Price ÷ Original Price)
How to Use the Double Discount Calculator
- Enter the original price of the product.
- Enter the first discount percentage.
- Enter the second discount percentage.
- Click Calculate.
The calculator instantly provides the final price after both discounts and the total effective discount percentage.
Example
Suppose a jacket originally costs $100, and the store offers a 20% discount followed by an additional 10% off.
- After the first discount: $100 × (1 – 0.20) = $80
- After the second discount: $80 × (1 – 0.10) = $72
- Total discount: 100 × (1 – 72 ÷ 100) = 28%
You pay $72 after both discounts, saving 28% in total.
FAQs
1. Can I just add the two discounts?
No, successive discounts are multiplicative, not additive.
2. What if the discounts are the same?
The formula still applies; discounts multiply.
