How to Calculate Double Discount
A double discount means applying two consecutive percentage discounts on an original price. Instead of adding both percentages together, each discount is applied sequentially, which results in a slightly smaller final discount than the sum of the two percentages.
Formula
The final price after two discounts is calculated as:
Final Price = Original Price × (1−First Discount/100) × (1−Second Discount/100)
The total discount amount is:
Total Discount = Original Price − Final Price
The total discount percentage is:
Total Discount Percentage = (Total Discount / Original Price) × 100
Example 1: Applying a 20% and 10% Discount on $500
- Given Data:
- Original Price = $500
- First Discount = 20%
- Second Discount = 10%
Step 1: Apply the First Discount
500 × (1−20/100) = 500 × 0.80 = 400
The price after the first discount is $400.
Step 2: Apply the Second Discount
400 × (1−10/100) = 400 × 0.90 = 360
The final price after both discounts is $360.
Step 3: Calculate the Total Discount
500 − 360 = 140
The total discount amount is $140.
Step 4: Calculate the Total Discount Percentage
(500/140) × 100 = 28%
The total discount percentage is 28%, not 30% (which would be incorrect if simply added).
Example 2: Apply 15% and 25% Discount on a $1000 Item
- Original Price = $1000
- First Discount = 15% × 0.85 = 850
- Second Discount = 25% × 0.75 = 637.50
- Total Discount Amount 1000 − 637.50 = 362.50
- Total Discount Percentage (362.50/1000) × 100 = 36.25%
