The Sale Price Calculator applies a discount percentage to a list price to find both the resulting sale price and the exact dollar amount saved. Enter the list price and the discount percent, and the calculator returns the final price a shopper would pay along with the savings in plain dollars.
Discount percentages are everywhere at checkout, from a "20% off" tag to a seasonal storewide sale, but converting that percentage into an actual dollar price and a concrete savings figure is the step that actually matters for a purchase decision. This calculator handles that conversion directly.

Apply the discount to find the sale price
The formula is Sale Price = List Price x (1 - Discount % / 100), and the dollar amount saved is simply List Price - Sale Price. Both figures come from the identical inputs, just presented two different ways.
Take a $100 list price marked 20% off. Multiplying $100 by (1 - 0.20), or 0.80, gives a sale price of exactly $80.00. The dollar amount saved is $100 - $80, or exactly $20.00. So a "20% off" tag on a $100 item translates directly into a final $80.00 price and a $20.00 savings.
See how the discount percent changes both figures
A larger discount percentage lowers the sale price and raises the dollar savings, while a smaller discount percentage raises the sale price and lowers the dollar savings, both changing in direct proportion to the percentage itself.
A 30% discount on the same $100 item would drop the sale price to $70.00 and raise the savings to $30.00, a $10.00 shift from the 20%-off scenario, precisely matching the 10-percentage-point difference in the discount rate applied.
The Sale Price Calculator makes this proportional relationship easy to verify directly, testing several discount levels against the same list price to see exactly how the final price and savings shift with each one.
Stack this with a coupon or additional discount
Some purchases apply more than one discount, such as a storewide sale percentage followed by an additional coupon code, and the two are typically applied sequentially rather than added together: the second discount is applied to the already-discounted sale price, not to the original list price.
Someone applying a 20% storewide discount followed by an additional 10% coupon should run this calculator twice, first from the $100 list price to reach an $80.00 sale price, and then a second time using that $80.00 figure as the new "list price" with the 10% coupon applied, arriving at a final price of $72.00 rather than the $70.00 a single combined 30% discount would produce.
Use this for everyday shopping decisions
Beyond retail markdowns, this same calculation applies to any scenario involving a stated percentage reduction from a starting price: a service provider offering a percentage discount for early payment, a subscription offering a percentage off for an annual plan instead of monthly, or a wholesale price sheet listing percentage discounts by volume tier.
In every case, the same Sale Price = List Price x (1 - Discount % / 100) formula converts the stated percentage into an actual price and dollar savings figure.
Know what this calculation assumes
This calculation assumes the discount percentage applies to the full list price entered and does not account for sales tax, which in most jurisdictions is calculated on the discounted sale price rather than the original list price.
It also does not account for any additional fees, shipping charges, or other adjustments that might apply between the listed sale price and a final checkout total.
Use the Sale Price Calculator to quickly convert any discount percentage into a concrete sale price and dollar savings figure, and add sales tax to the resulting sale price separately if a final out-the-door total is needed.
Frequently asked questions
How do you calculate a sale price from a discount percent?
A sale price is calculated as List Price x (1 - Discount % / 100). For a $100 item at 20% off, this is $100 x 0.80, giving a sale price of exactly $80.00.
What is the sale price and savings on a $100 item at 20% off?
A $100 item at 20% off has a sale price of exactly $80.00 and a dollar savings of exactly $20.00, since 20% of $100 is $20.
How do you apply two discounts, like a sale plus a coupon?
To apply two discounts, apply them sequentially rather than adding the percentages together: calculate the first discounted price from the original list price, then apply the second discount to that already-discounted price, not to the original list price.
Does the sale price calculation include sales tax?
No, this calculation only applies the stated discount percentage to the list price. Sales tax, where applicable, is typically calculated on the discounted sale price afterward, not on the original list price.
Is a 20% discount followed by a 10% discount the same as a 30% discount?
No, applying a 20% discount followed by a 10% discount on the already-discounted price results in a smaller total reduction than a single 30% discount. On a $100 item, 20% then 10% gives a final price of $72.00, while a single 30% discount gives $70.00.
Summary
The Sale Price Calculator applies Sale Price = List Price x (1 - Discount % / 100) to find both the final price and the dollar amount saved. A $100 item at 20% off has a sale price of exactly $80.00 and savings of exactly $20.00.
Stacked discounts, like a sale plus a coupon, apply sequentially to the already-discounted price rather than adding percentages together. Figures shown are estimates, general math, not financial advice.
