Discount Calculator

Multiply the price by the percent off and divide by 100 to get the amount off, then subtract it from the price. For 25% off $60, the amount off is 60 × 25 / 100 = $15, so you pay $45. A shortcut is to multiply by the share you still pay, here 0.75: 60 × 0.75 = $45.

The discount amount is the price times the discount percentage divided by 100. For $149.99 at 15% off, that is 149.99 × 15 / 100 = $22.50 rounded to the cent. If you know both prices instead, subtract the sale price from the original price. The "You save" line in the result shows this amount.

Subtract the discount amount from the original price, or multiply the price by (100 − discount) / 100. At 30% off $85, the amount off is $25.50 and you pay $59.50, which is 85 × 0.7. Choose "Sale price" in the calculator, enter the original price and the percent off, and it shows both numbers.

Divide the amount saved by the original price and multiply by 100. If a $60 item is marked down to $48, you save $12, and 12 / 60 × 100 = 20% off. Pick "Percent off" in the calculator and enter the original price and the sale price to get the percentage and your savings.

20% off $100 is $20, so the price drops to $80. 20% off $50 is $10, so you pay $40. In both cases you pay 80% of the price, which is the original price times 0.8. The same shortcut works for any price: 20% off $35 is $28.

Yes. Choose "Percent off", enter the original price and the sale price, and the calculator returns the percentage and the amount you save. From $120 to $90 it shows 25% off and $30 saved. The sale price cannot be higher than the original price, because that would be an increase.

Yes. Enter prices with cents, like 49.99, and rates with decimals, like 12.5 or 7.25, using a period as the decimal point. 12.5% off $49.99 is $6.25 off and $43.74 to pay. The calculator keeps the extra digits while it works and rounds only the figures it shows.

Yes, in two steps. A fixed amount comes off by plain subtraction: $15 off $60 leaves $45. To see what that is as a percentage, choose "Percent off" and enter 60 as the original price and 45 as the sale price. The result is 25% off, which helps you compare it with a percent-off coupon.

Yes. Choose "Two discounts" and enter both percentages. The second one applies to the price after the first, so they do not add up. 20% off followed by 10% off $100 leaves $72, a total of 28% off. 50% off plus 20% off is 60% off in total, not 70%. The order of the two discounts does not change the result.

It does not add sales tax, because rates vary by state, county and city, and some items are exempt. To include it, take the price after the discount and multiply by 1 plus the tax rate. A $64 sale price with 7% tax is 64 × 1.07 = $68.48. Whether tax is figured before or after a coupon depends on the type of coupon and your state.

The savings amount, shown as "You save", is the difference between the original price and the price you pay. It is the dollar value of the discount: at 20% off $80 it is $16. When you start from two prices, it is the original price minus the sale price, and the percent off is that difference as a share of the original price.

Yes. Retailers can check how deep a markdown is, find the percent off between a list price and a promotional price, or work back to a list price from a sale price. The calculator does not figure margin or markup, because both need the cost of the item, which it does not take. The percentage calculator helps with those.

Yes. The page works on phones and tablets as well as on a computer: the fields stack in one column, the buttons are large enough to tap, and the result stays visible at the bottom of the screen while you type. You can also copy the result or share a link that opens with your numbers filled in.

Your entries stay on your device. The math runs in your browser, so the prices and percentages you type are not sent to a server unless you send a problem report, which includes the values you entered. A link you copy with the share button contains your numbers in the address, so only share it if you are comfortable with that.

Start with 10%: move the decimal point one place to the left. On a $48 item, 10% is $4.80, so 20% off saves $9.60 and 30% off saves $14.40, and you pay $38.40 or $33.60. For 25% off, a quarter of the price comes off ($12 here), and for 50% off, half of it. The percentage calculator works out any other percent of a number.

Not necessarily. Percent off only means something against the right starting price. The Federal Trade Commission’s pricing guides say a "former price" should be an actual, bona fide price at which the item was offered for a reasonably substantial period, not an inflated tag. Compare the sale price with what other stores charge before you decide.
