The Discount Calculator finds the sale price and the amount saved when a list price is reduced by a percent or a fixed dollar amount. Enter the original price and the discount, and the Discount Calculator returns the discounted price, dollars saved, and, for stacked offers, the final price after each cut is applied in order.
Retail tags, coupons, and checkout promotions all rest on the same arithmetic: multiply by one minus the percent, or subtract a fixed amount. The Discount Calculator keeps that math exact to the cent so a shopper can compare offers without rounding surprises at the register.

Calculate a discounted price
The Discount Calculator computes a sale price from a list price and a discount percent. A percent-off discount multiplies the list price by one minus the discount rate, which leaves the portion still owed after the reduction. Shoppers use that sale price to compare tags before tax.
Sale price equals list price times (1 minus discount percent). A $80 item at 25% off becomes $80 x 0.75 = $60. The Discount Calculator shows that sale price beside the original list so the cut is visible, not buried in a single number. The same path works for any positive list price and any discount between 0% and 100%. At 0% the sale price equals the list; at 100% the sale price is $0 in this educational model.
A $199.99 jacket at 30% off is $199.99 x 0.70 = $139.993, which rounds to $139.99 when the tool keeps cent precision on the final ticket. Retailers sometimes round displayed cents by store policy. The Discount Calculator keeps full cent precision on the inputs given, so the arithmetic matches the formula rather than a particular POS rounding rule.
Find the amount saved
The Discount Calculator finds the amount saved as the gap between list price and sale price. Amount saved is the discount in dollars, which equals list price times the discount percent when the offer is percent-based. Dollar savings often decide a cart better than percent labels alone.
On the $80 list at 25% off, amount saved is $80 x 0.25 = $20, and sale price plus savings returns $60 + $20 = $80. The Discount Calculator reports both figures so a shopper can read the offer either as a final ticket or as cash left in pocket. Fixed-amount coupons reverse the order: the savings figure is entered first, and sale price is list minus that amount.
Comparing two deals is often clearer in dollars saved than in percent alone. A 15% cut on a $200 jacket saves $30; a 40% cut on a $50 shirt saves $20. The larger percent is not the larger win. The Discount Calculator makes those dollar outcomes explicit so a cart decision rests on cash, not on the louder sticker.
Apply a fixed-amount discount
The Discount Calculator applies a fixed-amount discount by subtracting dollars off from the list price. Coupons stated as "$10 off" or "$25 off" use this mode instead of a percent. Fixed coupons are common at checkout when a code is currency-denominated.
Sale price equals list price minus the fixed discount. A $120 cart with a $15 coupon becomes $105, with $15 saved. If the coupon exceeds the list price, this educational model floors the sale price at $0 and caps savings at the list price; real checkout systems may reject the coupon or apply store-specific rules. The Discount Calculator does not invent those store rules; it only subtracts the amount entered.
Percent and fixed modes answer different tags. A "30% off" sticker needs the percent path; a "$10 off $50" coupon needs the fixed path. Mixing them without care is how shoppers misread a promotion and understate what is still due at the till.
Stack multiple discounts
The Discount Calculator stacks multiple discounts by applying each cut to the price that remains after the previous cut. Stacked discounts are multiplicative, not a simple sum of percents, so order and method both matter. Merchant policy still governs which cuts may combine.
Start with $100. A 20% off sale leaves $80. A further 10% off that remaining price leaves $80 x 0.90 = $72. Total savings are $28, which is 28% off the original, not 30%. Adding the percents (20% + 10% = 30%) would wrongly predict a $70 ticket. The Discount Calculator applies discounts in the order entered so the multiplicative path is visible step by step.
Some stores apply a coupon after a sale price; others apply the larger discount only. A third pattern applies employee discounts after coupons. The Discount Calculator models sequential application on the running price. Confirm the merchant's stacking policy before treating a result as a checkout promise.
Another worked stack: $250 list, 15% off, then $20 off the reduced price. After 15% the running price is $212.50; after $20 it is $192.50, for $57.50 saved. Reversing order ($20 first, then 15%) yields $195.50, a different ticket. The Discount Calculator should apply cuts in the order the merchant states, because order changes the final price when percent and dollar discounts mix.
Frequently asked questions
How is sale price calculated?
Sale price is calculated by reducing the list price by the discount. The Discount Calculator multiplies list by (1 minus percent off) for percent discounts, or subtracts a fixed dollar amount for amount-off coupons. An $80 item at 25% off has a sale price of $60.
How is the amount saved calculated?
The amount saved is calculated as list price minus sale price. The Discount Calculator also shows list times the discount percent when the offer is percent-based. On an $80 list at 25% off, the amount saved is $20.
Can the Discount Calculator handle a fixed dollar coupon?
The Discount Calculator can handle a fixed dollar coupon by subtracting the coupon amount from the list price. A $120 list with $15 off becomes $105. If the coupon is larger than the list, this model floors sale price at $0.
Do stacked discounts add as simple percents?
Stacked discounts do not add as simple percents. The Discount Calculator applies each discount to the remaining price, so 20% then 10% on $100 yields $72, not $70. The combined cut is 28% off the original list, not 30%.
Does the Discount Calculator include sales tax?
The Discount Calculator does not include sales tax. Sale price and savings are computed on the pre-tax list. Add local tax to the sale price afterward if a tax-inclusive total is needed.
What happens at 100% off?
At 100% off, the Discount Calculator returns a sale price of $0 and savings equal to the full list price in this educational model. Real promotions labeled "100% off" may still exclude tax, shipping, or excluded SKUs.
Summary
The Discount Calculator turns a list price and a discount into a sale price and an amount saved, using either percent off or a fixed dollar cut. Percent mode multiplies by (1 minus the rate), so $80 at 25% off becomes $60 with $20 saved; fixed mode subtracts the coupon dollars directly from the list.
Stacked discounts multiply in sequence, which is why 20% then 10% on $100 ends at $72 rather than a naive 30% off. Tax is left out of the ticket maths so the discount itself stays clear. These results are estimates for information only, not financial advice.
