You can also work backwards: if you know the sale price and the original price, you can determine the discount percentage manually using the formula below.
The core discount formula is straightforward:
Sale Price = Original Price − (Original Price × Discount% ÷ 100)
Savings = Original Price × Discount% ÷ 100
Discount% = ((Original Price − Sale Price) ÷ Original Price) × 100
Divide the original price by 10. That’s your discount amount. Subtract it from the original price to get the sale price. Example: 10% off $3,000 = $300 saved → sale price $2,700.
Multiply the original price by 0.20. Subtract the result from the original price. Example: 20% off $5,000 = $1,000 saved → sale price $4,000.
Multiply the original price by 0.30 to get the savings, then subtract from the original. Example: 30% off $10,000 = $3,000 saved → sale price $7,000.
Divide the sale price by (1 − discount/100). Example: if a product costs $4,000 after a 20% discount, the original price = 4,000 ÷ 0.80 = $5,000.
Not all discounts work the same way. Understanding the type helps you evaluate the real value of a deal:
A fixed % off the original price. Most common in retail sales and online stores.
A set amount deducted from the price regardless of the original cost.
BOGO deals – get an extra item free or at a reduced price with a purchase.
The more units you buy, the more you save. Common in wholesale purchasing.
Offered by suppliers to distributors, enabling flexible consumer pricing.
A code applied at checkout for a specific percentage or fixed discount.
Use these strategies to get the best deal every time:
A discount calculator is a tool that computes the reduced price of a product after a percentage or fixed discount is applied. It instantly shows you the sale price and exactly how much money you save – without any manual math.
Subtract the sale price from the original price, divide that number by the original price, then multiply by 100. For example: (5,000 − 4,000) ÷ 5,000 × 100 = 20% discount.
Multiply the original price by 0.20 to find the discount amount, then subtract from the original. Example: $8,000 × 0.20 = $1,600 saved → final price $6,400. Or simply use the calculator above.
Fake discounts (also called fictitious pricing) occur when a retailer artificially inflates the “original” price before marking it down, making the discount look bigger than it really is. Always check the price history of a product before assuming a sale is a good deal.
Divide the sale price by (1 − discount% ÷ 100). If an item costs $3,600 after a 10% discount, the original price = 3,600 ÷ 0.90 = $4,000.
Clearance sales happen when retailers need to clear out old stock – especially seasonal goods – to make room for new inventory. Products may be discounted heavily because unsold items cost money to store and lose value over time.
Enter the original price in A1 and sale price in B1. In C1, type =A1-B1 for the discount amount. In D1, type =(C1/A1)*100 for the discount percentage. Format D1 as a percentage for clean display.
