Double Discount Calculator
You may visit a store and it advertises 10% off followed by another 10% discount. Many people may think that the total discount is 20%. But in reality, that is not how pricing works. This misunderstanding discounts can cause confusion, wrong expectations and sometimes wrong buying decisions.
Our Double Discount Calculator helps remove that confusion by allowing you to find the actual price after both successive discounts are applied.
What This Double Discount Calculator Helps You Find
With this calculator you can find the true price after successive discounts are applied.
- Find the final price after two discounts
- Calculate the effective discount rate, not just the advertised one
- Understand how successive discount percentages really work
- Compare original price vs net price clearly
- Avoid overestimating savings during sales or promotions
Double discount calculation becomes especially useful in seasonal sales, coupon combinations, or promotional offers.
Double Discount Meaning (Why Two Discounts Are Not Additive)
The double discount means applying two discounts, one after the other, not together.
Each discount is applied to the already reduced price, not the original price. Because of this, two 10% discounts do not equal a flat 20% reduction.
This concept is also known as:
- Successive discount
- Combined discount
- Multiplicative discount
Understanding the difference is so important for accurate discount calculation and smart buying decisions. For single discounts, you can simply calculate the percentage off using the Percent Off Calculator to see the discounted price.

What Is the Double Discount Formula?
Double discounts are applied sequentially rather than added.
Final Price = Original Price × (1 − First Discount) × (1 − Second Discount)
This is the reason why the effective discount is always less than the sum of the two discounts.
For users who work with spreadsheets, the same logic applies when using a double discount formula Excel sheet. The calculator simply automates this process without manual errors.
How Do I Calculate the Double Discount?
If you want to calculate a double discount manually, you have to:
- Apply the first percentage discount to the original price
- Take the reduced price and apply the second discount
- Compare the final result with the original price to find total savings
Our double discount performs this automatically. It helps reduce calculation mistakes and saves time.

Frequently Asked Questions About Double Discounts
The following are some commonly asked questions regarding double discounts.
Two 10% discounts do not equal 20%. The effective discount is 19%, because the second discount is applied to a reduced price, not the original price.
Two 20% discounts result in a 36% total discount, not 40%. This difference highlights why understanding successive discounts is important.
If the original price is $100, after applying two 10% discounts: First 10% discount reduces $100 to $90, Second 10% discount reduces $90 to $81. Final price is $81, with a total savings of $19.
