Find out what you pay and what you save. Enter the original price and percent off, then add an extra percentage-off coupon or sales tax if needed.
—
Enter the original price and the advertised percent off. For a 30% discount, enter 30. Use the same fields for a student discount, a clearance markdown, or a storewide sale.
If the store allows another percentage-off coupon, put it in Extra coupon. It applies to the price left after the first discount. Enter a Sales tax rate for an estimate including tax, or leave it blank to calculate the price before tax.
You pay shows the discounted price plus any tax you entered. You save shows the amount taken off the original price before tax. The Price breakdown lists both discounts, the subtotal, and tax separately.
A 30% off sign means you save 30% of the original price and pay the remaining 70%. This discount calculator works out both amounts so you can tell the savings apart from the sale price.
Original price × (percent off ÷ 100)Original price × (1 − percent off ÷ 100)Suppose a pair of shoes costs $79.99 and is 30% off. Multiply $79.99 by 0.30 to find the discount, or by 0.70 to go straight to the price you pay.
You save $24.00 and pay $55.99 before tax. Both amounts are displayed to the nearest cent.
For a $100 item, the discount percentage is also the number of dollars you save. These examples assume one discount and no tax. Use the sale price calculator above for a different price.
| Percent off | You save | You pay |
|---|---|---|
| 10% | $10.00 | $90.00 |
| 20% | $20.00 | $80.00 |
| 25% | $25.00 | $75.00 |
| 30% | $30.00 | $70.00 |
| 50% | $50.00 | $50.00 |
| 70% | $70.00 | $30.00 |
An extra coupon comes off the already reduced price. If a $100 jacket is 20% off, it drops to $80. An extra 10% off takes another $8 off that $80, bringing the price to $72 before tax.
The combined discount is 28%, not 30%. A straight 30% discount would bring the same jacket down to $70.
| Step | Amount off | Price left |
|---|---|---|
| First discount: 20% of $100 | $20.00 | $80.00 |
| Extra coupon: 10% of $80 | $8.00 | $72.00 |
For two successive discounts, use Sale price = original price × (1 − first discount ÷ 100) × (1 − second discount ÷ 100). The calculator handles this double discount when you fill in Extra coupon. Check that the retailer allows the offers to be used together.
It depends on the price. A $10 coupon always saves $10, while a 20% discount saves more as the price rises. Assuming both offers apply to the same purchase with no minimum spend or savings cap, they break even at $50.
| Original price | Save 20% | Save $10 | Better offer |
|---|---|---|---|
| $25.00 | $5.00 | $10.00 | $10 off |
| $50.00 | $10.00 | $10.00 | Same savings |
| $80.00 | $16.00 | $10.00 | 20% off |
To compare your own offers, calculate the percentage-off price above and compare it with the original price minus the dollar-off coupon. The Extra coupon field takes a percentage, so a $10 coupon should not be entered as 10 there.
For Black Friday or clearance deals at different stores, compare the final amounts as well as the discount signs. Different starting prices, shipping charges, and coupon exclusions can change which offer costs less.
With an $80 item at 25% off, the subtotal is $60 and the savings are $20. Enter an 8% tax rate and this calculator adds $4.80, so You pay becomes $64.80. You save stays at $20 because it measures the merchandise discount before tax.
The calculation is Tax = discounted subtotal × tax rate ÷ 100, then You pay = discounted subtotal + tax. The entered rate applies to the whole discounted subtotal.
They give different answers. Twenty percent of $80 is $16. Twenty percent off $80 means subtract that $16, leaving $64 to pay. A percentage off calculator gives you the reduced price as well as the amount saved.
Find 10% by dividing the price by 10, then multiply that amount by 3 and subtract it from the price. For $60, 10% is $6, so 30% is $18 and the sale price is $42. You can also multiply the original price by 0.70.
Subtract the sale price from the original price, divide by the original price, and multiply by 100: Discount % = (original − sale) ÷ original × 100. A price drop from $120 to $90 saves $30, which is 25% of $120. The form above calculates a sale price from a known percentage; use this formula when you know both prices instead.
Divide the sale price before tax by the share of the original price you paid: Original price = sale price ÷ (1 − discount % ÷ 100). If you paid $40 after 20% off, the original price was $40 ÷ 0.80 = $50. Adding 20% to $40 would give $48, which does not undo the discount. This is a manual reverse calculation; the form above requires the original price. At 100% off, the sale price alone cannot tell you the original price.
Two percentage discounts give the same result in either order before rounding. A fixed dollar amount combined with a percentage is different: on $100, 20% off then $10 off leaves $70, while $10 off then 20% off leaves $72. This calculator supports two percentage discounts. The store's terms determine whether discounts can be combined and in what order.
For two equally priced items, yes: two $40 items normally cost $80, and taking 50% off the second saves $20, or 25% of the pair's original price. If the discount applies to a cheaper item, the overall percentage is lower. The form above handles percentage discounts on one entered price; it does not work out buy-one-get-one eligibility or item pairing.
