Find the sale price, the discount percentage or the original price, including stacked discounts.
Quick answer
The sale price is $60.00 and you save $20.00. To get it, multiply the price by 0.75 (that is 100% minus 25%).
| Discount | You save | Sale price |
|---|---|---|
| 10% | $8.00 | $72.00 |
| 20% | $16.00 | $64.00 |
| 25% | $20.00 | $60.00 |
| 30% | $24.00 | $56.00 |
| 40% | $32.00 | $48.00 |
| 50% | $40.00 | $40.00 |
These figures are computed with the same formulas as the Discount Calculator above. Change the inputs in the tool to see your own result.
The Discount Calculator tells you the sale price and how much you save after a percentage discount, and can also work backwards. Enter an extra "second" discount to see the real total for stacked offers like 20% off plus an extra 10%, and add sales tax to see what you will actually pay at the till. Switch modes to find the discount percentage from two prices, or the original price from a sale price and its discount.
Made for everyone. Typical uses:
A $150 item at 20% off costs $120 and saves $30. Two stacked discounts of 20% then 10% on $100 leave $72, which is 28% off in total, not 30%, because the second discount applies to the reduced price. A $200 item at 25% off with 8% sales tax comes to $150 plus $12 tax, or $162. A price that drops from $80 to $60 is 25% off, and a sale price of $60 that is already 25% off started at $80.
Stacked discounts are applied one after the other, which is how most retailers do it. Some coupons instead apply to the full price or exclude sale items; check the terms of your offer. Sales tax is added after the discounts, which is the usual rule but not universal.

Expert Tip
Two discounts never add up to their sum. Twenty percent off followed by ten percent off is 28% off, so a single 30% off coupon is always the better deal.
A discount takes a percentage off the original price. The saving is the price multiplied by the discount divided by 100, and the sale price is the price minus the saving. A $150 item at 20 percent off saves $30 and costs $120. Equivalently, you pay 80 percent of the price, so multiplying by 0.80 gives the sale price in one step.
The calculator has three modes for the three questions shoppers ask: what will I pay after this discount, what discount am I getting from these two prices, and what was the original price before this sale.
Stores often advertise "20 percent off plus an extra 10 percent". The second discount applies to the already reduced price, so the total is not 30 percent. On a $100 item, 20 percent off gives $80, and 10 percent off that gives $72. The combined discount is 28 percent, calculated as 1 − (0.80 × 0.90). The longer the stack, the more the sum overstates the real saving.
This also means order does not matter, but comparing offers does. A single 30 percent coupon ($70) beats 20 percent then 10 percent ($72), even though both sound similar. Put both discounts in the calculator to see the exact final price and the true total percentage.
Sometimes a shop shows a crossed-out price and a sale price without saying the percentage. Subtract the sale price from the original, divide by the original and multiply by 100. If a jacket falls from $80 to $60, the discount is (80 − 60) ÷ 80 = 25 percent. Use the "Find the discount %" mode to check that a "sale" is as good as it looks; it also shows a price increase if the sale price is higher.
Be cautious of reference prices that were never really charged. A sale is only a saving if the original price was a genuine price. Comparing the sale price with what other retailers charge is a better test than the percentage on the label.
The reverse question is common in accounting and when comparing offers: the price is $60 after 25 percent off, so what was it before? Divide the sale price by (1 − the discount as a decimal): 60 ÷ 0.75 = $80. Avoid the tempting shortcut of adding 25 percent to $60, which gives $75 and is wrong, because 25 percent was taken off the larger, original amount.
The same maths applies to prices after tax or after a fee: divide by (1 + rate), not subtract the rate. The Sales Tax Calculator and Percentage Calculator handle those cases directly.
The price on the shelf is not always the price at the till. Enter your local sales tax to see the total after tax. Tax is usually charged on the discounted price, so a $200 item at 25 percent off is $150, and 8 percent tax adds $12 for a total of $162. Some manufacturer coupons are treated differently and taxed on the full price, so check the rules that apply. If several items are involved, calculate each one or the total, but apply the same steps in the same order.
Every discount reduces profit by more than it seems. A product with a 40 percent margin sold at 20 percent off has a margin of only 25 percent, so you must sell many more units to earn the same profit. Before you run a promotion, check the margin at the sale price with the Profit Margin Calculator and see how many extra sales you need to break even.
