Multiply the original price by the discount percentage as a decimal to find the discount amount, then subtract from the original price. Example: 25% off 80 dollars — discount = 80 x 0.25 = 20 dollars, sale price = 80 - 20 = 60 dollars. Alternatively, multiply by (1 - discount rate): 80 x 0.75 = 60 dollars. Our calculator does both steps instantly.
Divide the sale price by (1 - discount rate). If a sale price is 75 dollars after 25% off: original price = 75 / (1 - 0.25) = 75 / 0.75 = 100 dollars. This is useful when a price tag shows only the sale price and you want to verify the original price or the exact discount percentage being applied.
Stacked discounts are not simply additive. A 20% discount followed by a 10% discount does not equal 30% off. Calculate each in sequence: on a 100 dollar item, 20% off gives 80 dollars, then 10% off 80 dollars gives 72 dollars. The effective total discount is 28%, not 30%. Use this calculator twice — apply the first discount, then use the result as the starting price for the second.
In retail: 10% is noticeable, 20-25% is the minimum threshold for a genuine sale, 30-50% is a major sale that drives urgency, and 50%+ signals clearance. A concrete saving amount is often more persuasive than the same saving as a percentage — our calculator shows both the percentage and the exact dollar amount saved.
Total savings = original price x discount rate x quantity. Example: 4 items originally 50 dollars each at 30% off — savings = 50 x 0.30 x 4 = 60 dollars total. The total cost is (50 x 4) - 60 = 140 dollars. Our calculator includes a quantity field so you can see total savings across multiple units in one step.
Discount percentage = (original price - sale price) / original price x 100. If an item was 80 dollars and is now 60 dollars: discount = (80 - 60) / 80 x 100 = 25%. This tells you the exact percentage taken off regardless of how the retailer advertises the sale — useful for verifying that the advertised discount matches the actual price reduction.
Generally, discounts are applied to the pre-tax price first, and tax is then calculated on the discounted price. On a 100 dollar item at 20% off with 8% sales tax: discounted price = 80 dollars, tax = 80 x 0.08 = 6.40 dollars, total = 86.40 dollars. Always clarify whether a promotional price is pre-tax or the final total when comparing deals.
A discount reduces the price at the point of purchase — you pay less immediately. Cashback gives you a portion of the price back after the purchase via a bank transfer, reward points or statement credit. The mathematical saving is the same, but cashback requires more steps and the money is received later. Discount is simpler and immediate; cashback may offer higher effective savings when combined with credit card rewards.
