Percent Off Formula (Explained Simply)
This calculator uses a straightforward formula to calculate the discounted price.
Formula:
Discount Amount = Original Price × (Discount Percentage ÷ 100)
Discounted Price = Original Price – Discount Amount
Let’s break it down with an example:
Example:
Original Price: $200
Discount: 25%
Step 1: Calculate the discount amount
200 × (25 ÷ 100) = 200 × 0.25 = $50
Step 2: Subtract the discount from the original price
200 – 50 = $150
So the final price after a 25% discount on $200 is $150.
