This discount calculator estimates the amount saved and the final sale price from an original price and a discount percentage. It can also solve for a missing original price, sale price, or percentage when the other values are known.
Use the result as a price comparison aid. Taxes, shipping, fees, coupons, minimum spend rules, and store rounding may change the amount charged at checkout.
A discount reduces an original price by a stated percentage or fixed amount. The discount amount is the original price multiplied by the discount rate, and the sale price is the original price minus that amount.
A percentage discount is relative to the original price. Two discounts applied one after another are usually multiplied sequentially rather than simply added together.
Discount = original price × discount rateConvert 25% to 0.25, then multiply it by the original price.
Sale price = original price − discountSubtract the discount amount from the original price, then apply any separate tax or fee assumptions.
Final price = original price × (1 − rate 1) × (1 − rate 2)The second discount is applied to the already reduced price unless the seller explicitly defines a combined discount.
A 20% discount followed by 10% is an overall reduction of 28%, not 30%, because the second discount applies to the reduced price.
What is the sale price of 80 with a 25% discount?
How much is saved on 250 at 40% off?
How can a 15 fixed discount be compared with 10%?
What is the final price after 20% and then 10% off 100?
What was the original price if 30% off produces a sale price of 70?
What is charged when 200 receives 15% off and then 10% tax?
The savings figure is the amount removed from the original price before separate taxes and fees. The sale price is not necessarily the final checkout total.
Check whether the advertised original price is genuine, whether the discount applies to all items, and whether coupons can be combined.
Adding sequential discount percentages instead of applying them one after another.
Applying a discount to the tax-inclusive total when the offer applies before tax.
Confusing a percentage discount with a fixed currency reduction.
Ignoring exclusions, minimum spend, expiry dates, shipping, or checkout fees.
This tool calculates arithmetic only. It cannot verify a retailer’s original price, promotion terms, product exclusions, or advertising compliance.
Review the offer details before paying, especially when a discount is combined with financing, subscriptions, or recurring charges.
Multiply the original price by the percentage written as a decimal, then subtract the discount amount from the original price.
The savings are 10 and the sale price is 40.
Usually no. Sequential discounts are applied one at a time, so the second percentage applies to the reduced price.
It depends on the transaction and local rules. Run the discount first only when the offer applies before tax.
Yes. Divide the sale price by one minus the discount rate, provided the sale price came from a percentage discount.
Only if the offer terms say so. Enter shipping separately when estimating the checkout total.
Taxes, shipping, fees, rounding, exclusions, and coupon rules may not be included in the basic calculation.
A normal price discount cannot reduce a positive price below zero. Check the inputs if a result is negative.
