Discount formulas
Price after discount
To calculate the final price after a percentage discount, multiply the original price by the discount percentage and subtract the discount amount from the original price.
Formula:
Final Price = Original Price - (Original Price × Discount / 100)
Example:
20% off 100 = 80
Discount amount
To calculate how much money you save, multiply the original price by the discount percentage.
Formula:
Discount Amount = Original Price × Discount / 100
Example:
20% of 100 = 20 saved
Discount percentage
To find the discount percentage from an original price and a sale price, subtract the sale price from the original price, divide by the original price and multiply by 100.
Formula:
Discount Percentage = ((Original Price - Sale Price) / Original Price) × 100
Example:
From 100 to 75 = 25% discount
Multiple discounts
Multiple discounts are applied one after another, not added together directly.
For example, 20% off and then another 10% off is not the same as 30% off. First, the 20% discount is applied to the original price. Then, the 10% discount is applied to the reduced price.
Example:
200 with 20% off = 160
160 with another 10% off = 144
Total effective discount = 28%
