Discount Formula
Use this formula to manually calculate a percentage discount:
discounted price = original price – (original price Ă— discount % / 100)
Example:
Original price = $90
Discount = 20%
Savings = $18
Final price = $72
How to Calculate Discount & Sale Price
Steps to follow:
- Know the original price (e.g., $120)
- Apply the discount percentage (e.g., 25%)
- Calculate savings (25% of $120 = $30)
- Subtract from original price ($120 – $30 = $90)
That’s your final sale price!
Types of Discounts Explained
- Quantity Discounts: Save more when you buy in bulk
- Trade Discounts: Wholesale or B2B markdowns
- Promotional Discounts: Coupons, seasonal sales, flash deals
Common Discount Calculations
- 10% off = original price Ă— 0.10
- 20% off = original price Ă— 0.20
- 30% off = original price Ă— 0.30
Subtract these from the original price for your final cost.
How to Spot Fake Discounts
Watch out for:
- Inflated “original” prices
- Fake “before and after” pricing tactics
- Misleading BOGO deals with hidden conditions
Always calculate the real discount before buying.
Finding the Original Price from a Discounted One
If you have the discounted price and discount percentage, here’s how to find the original:
- Convert the discount to a decimal (e.g., 20% → 0.2)
- Subtract from 1 (1 – 0.2 = 0.8)
- Divide the discounted price by the result
Example: $80 / 0.8 = $100 original price
Use Excel for Discount Calculations
- A1: Original price
- B1: Discounted price
- C1: =A1 – B1 (savings)
- D1: =(C1/A1)*100 (discount percentage)
Format D1 as a percentage for clarity.
