Need to calculate a stacked percentage discount on an amount? Is it a double, triple, or multi-step discount?
For example, do you need to calculate a discount of 50 + 20 + 10? Or more generally X% + Y% + Z%?💲✂️
Well, just use the discount calculation tool below! 👇
Enter the amount, set discounts and click "Calculate Discounted Amount"

Enter the discounts % by following the boxes in succession
Click the "Calculate Discounted Amount" button
The double, triple, or multi-step discount calculation criterion
Let's simulate the calculation of a multiple discount, step by step.
Suppose the initial amount is X to which a successive / progressive discount of 50+30+20 is to be applied.
Apply the first discount (50%) to the initial amount. We will thus have the amount after the first discount:
Amount after first discount = X * 0.5
Apply the second discount (30%) to the amount obtained previously:
Amount after second discount = Amount after first discount - (Amount after first discount * 0.3)
As before, apply the third discount (20%) to the amount obtained in step 2:
Final amount = Amount after second discount - (Amount after second discount * 0.2)
See an example
Suppose the initial amount is 100.
Apply the first discount (50%):
Amount after first discount = 100 * 0.5 = 50
Apply the second discount (30%):
Amount after second discount = 50 - (50 * 0.3) = 50 - 15 = 35
Apply the third discount (20%):
Final amount = 35 - (35 * 0.2) = 35 - 7 = 28
Therefore, the final amount after applying consecutive discounts of 50%, 30%, and 20% is 28.
The multiple discount formula
OK, now let's see and explain the formula for calculating multiple discounts.
Formula with Two Discounts
The first formula calculates the new price after applying two discounts, denoted as x and y. The formula is presented as follows:
The Double Discount Formula
New Price = Initial Price × (1 - x) × (1 - y)
x: The first discount rate, expressed as a decimal.
y: The second discount rate, expressed as a decimal.
Formula with Multiple Discounts (Triple, Quadruple and more)
The second formula extends the first by including an additional discount and the possibility of further unspecified discounts between the second and the last. This is represented with the variable z and ellipsis for potential additional discounts. The formula is:
