Calculate discounted prices, savings, stacked discounts and find the discount percentage between two prices. Four modes in one tool.
Original price and discount %
Single, double, reverse or find %
Final price, savings and details
Calculating a percentage discount is essential for smart shopping and business pricing. This calculator offers four different modes for every scenario.
The basic formula: Sale price = Original price × (1 - Discount/100). If an item costs $100 and the discount is 25%, you pay $100 × 0.75 = $75, saving $25.
When two discounts are combined, the second applies to the already-reduced price. 20% + 10% off doesn’t make 30% — it’s 28%: $100 × 0.80 = $80 × 0.90 = $72. The effective discount is always less than the sum of individual discounts.
If you know the sale price and discount percentage, find the original: Original = Sale price / (1 - Discount/100).
To know how much discount you got: Discount % = ((Original - Sale) / Original) × 100. Useful for comparing offers and finding which deal is truly better.
Multiply the original price by the discount percentage and divide by 100. The result is your savings. Subtract from the original price to get the final price.
Stacked discounts are applied one after the other: the first discount on the original price, then the second on the already-reduced price. The effective discount is always less than the sum of the two.
No. Two 50% discounts applied sequentially give a 75% effective discount. $100 → $50 → $25. Total savings is $75, not $100.
Divide the sale price by (1 - discount/100). Example: $72 with 20% off → 72 / 0.80 = $90 was the original price.
Use the “Find %” mode to calculate the actual discount percentage between the full price and sale price. Compare effective discounts, not advertised ones.
The discount is applied before tax. Calculate the discounted price first, then add tax. This calculator handles the correct order automatically.
Enter the quantity to see the total cost. Savings are multiplied by the number of items, useful for bulk purchases or multiple orders.
