A percent-off sale is easy in principle but easy to fumble in your head at the register. This calculator takes an item’s original price and a discount percentage, then returns exactly how many dollars you save and the final price you pay. It is handy for checking storefront markdowns, stacking a coupon onto a sale, or sanity-checking whether a deal is as good as it looks.
Formula
Savings = Price × (Discount / 100); Final = Price − Savings
- Price
- Original price before any discount
- Discount
- Discount rate as a percentage
- Savings
- Dollar amount taken off the price
- Final
- Price paid after the discount is applied
How it works
- Enter the original (pre-discount) price of the item.
- Enter the discount as a percentage, for example 25 for a 25%-off sale.
- The calculator multiplies the price by the percentage to find your savings, then subtracts that from the original price to give the final amount you pay, both rounded to cents.
Worked example
An item priced at $120 with a 25% discount.
- Savings: 120 × 25 / 100 = $30.
- Final price: 120 − 30 = $90.
You save $30, paying a final price of $90.
Frequently asked questions
- How do I calculate a percentage discount?
- Multiply the original price by the discount percentage divided by 100 to get the savings, then subtract that from the price. For $120 at 25% off, savings are $30 and the final price is $90.
- How do I handle two discounts that stack?
- Stacked discounts apply one after another, not added together. Run the first percentage here to get the reduced price, then enter that new price with the second percentage; 20% then 10% is not the same as a single 30%.
- Does this calculator add sales tax?
- No. It returns the pre-tax discounted price only. If your purchase is taxable, apply your local sales-tax rate to the final price shown to get the amount you actually pay at checkout.
- Can I find the original price from the sale price?
- This tool works from the original price down to the sale price. To reverse it, divide the sale price by (1 − discount/100); a $90 price after 25% off implies an original of 90 ÷ 0.75 = $120.
