How Discounts Are Calculated
A discount reduces the original price by a set percentage. The discounted price is calculated by multiplying the original price by the discount percentage and subtracting that amount.
Formula: Discounted Price = Original Price × (1 − Discount% ÷ 100)
For example: $80 with a 25% discount = $80 × 0.75 = $60 (saving $20)
Common Discount Examples
10% off $50 = $45 (saving $5)
20% off $100 = $80 (saving $20)
25% off $80 = $60 (saving $20)
50% off $200 = $100 (saving $100)
Black Friday 30% off $150 = $105 (saving $45)
FAQs
How do I calculate a discount?
Multiply the original price by the discount percentage divided by 100, then subtract from the original price. For example 25% off $80 is $80 × 0.25 = $20 saving, so you pay $60.
How do I find the original price before a discount?
Divide the sale price by (1 minus the discount percentage as a decimal). For example if you paid $60 after a 25% discount, the original was $60 ÷ 0.75 = $80. Use the Find Original Price mode above.
How do I calculate what percentage discount I got?
Subtract the sale price from the original price, divide by the original price and multiply by 100. For example ($80 − $60) ÷ $80 × 100 = 25% discount.
What is the difference between discount and cashback?
A discount reduces the price before you pay. Cashback gives you money back after you pay. The end saving is the same but the timing differs.
