# Triple Discount Calculator

How do I calculate a triple discount?What is the triple discount formula?FAQs

This calculator lets you set a cumulative discount. Each discount is calculated from the price AFTER the previous one was applied (and not from the original price). For example, if the original price was $100 and you have 20%, 10% and 15% discounts. First, we're doing$100 − 20% = $80. Then$80 − 10% = $72. Then$72 − 15% = 61.20. You can use our percentage calculator to speed up this calculation.

## How do I calculate a triple discount?

To determine the price after a triple discount, you need to:

3. Multiply together the three numbers from Step 2.
4. Multiply the result by the initial price.
5. You've obtained the price after three discounts.

## What is the triple discount formula?

The formula for the triple discount is the following:

new price = initial price × (1 − r1) × (1 − r2) × (1 − r3)

where:

• r1 — First discount;
• r2 — Second discount; and
• r3 — Third discount.
FAQs

### What is the total discount after three discounts of 15%?

The total discount is almost 39%. Indeed, observe that (1 − 0.15) × (1 − 0.15) × (1 − 0.15) = 0.85 × 0.85 × 0.85 = 0.6141. This means that the new price is 61.41% of the initial price. In other words, the total discount is 100% − 61.41% = 38.59%.
