How to Calculate a Discount

Calculating a discount is a common task whether you're shopping during a sale or creating pricing for your own business. The process is simple and can be done in two main ways.

Method 1: Calculate Savings First

This is the most intuitive method. You first determine the value of the discount (how much you save) and then subtract it from the original price.

Step 1: Find the Savings Amount

Savings = Original Price × (Discount % / 100)

Step 2: Calculate the Final Price

Final Price = Original Price - Savings

Example: An item costs $80 and is on sale for 25% off.

• Savings = $80 × (25 / 100) = $20.
• Final Price = $80 - $20 = $60.

Method 2: Calculate Final Price Directly

This is a quicker method if you only need the final price. You calculate the percentage of the price you still have to pay and multiply it by the original price.

Final Price = Original Price × (1 - (Discount % / 100))

Example: Using the same $80 item with a 25% discount.

• You pay 100% - 25% = 75% of the original price.
• Final Price = $80 × (1 - 0.25) = $80 × 0.75 = $60.
