Percentage Discount Calculator
Percentage discounts are everywhere — online shopping, storewide sales, clearance events, coupon codes, holiday promotions, and everyday retail pricing. This percentage discount calculator shows you exactly how much money you save and what the final price will be after applying a percent‑off discount. It works for any price and any discount, making it ideal for shoppers, bargain hunters, and anyone comparing sale prices.
How percent-off discounts work
A percent-off discount reduces the original price by a certain percentage. The math behind it is simple, and uses the standard discount formula:
discount = (P/100) × V
final price = V − discount
Here, P is the discount percent and V is the original price.
Example: 13% off a $65 item discount = (13/100 × 65) = $8.45 final price = 65 − 8.45 = $56.55
This is the same math used by stores during Black Friday, Cyber Monday, clearance sales, and coupon promotions. Whether you're comparing prices or checking if a deal is worth it, this calculator gives you the exact savings and final cost.
Examples of common discount calculations
Example 1: 20% off $80
discount = (20/100 × 80) = 16
final price = $64
Example 2: 35% off $120
discount = (35/100 × 120) = 42
final price = $78
Example 3: 10% off $250
discount = (10/100 × 250) = 25
final price = $225
Example 4: 50% off $40
discount = (50/100 × 40) = 20
final price = $20
These examples show how percent-off discounts apply to clothing, electronics, groceries, restaurant deals, subscription promotions, and more.
Reverse discount: find the percentage saved
If you already know the dollar amount saved and want to find the discount percentage, use the reverse formula:
P = (100 / V) × savings
Example: You saved $12 on a $60 item P = (100 / 60) × 12 = 20%
This is useful when stores show only the sale price and you want to know how big the discount really is.
