Discount Calculator
Sale price = original x (1 - discount / 100). Stacked discounts apply one after another.
Enter price and discounts
Enter the original price and the discount percentage. The calculator returns the savings amount and the sale price.
Use it for retail sales, coupons, clearance pricing, subscription deals and quick shopping checks.
If there are two percentage discounts, apply them in order unless the store says they are added together. Most stacked discounts are applied to the reduced price, not the original price twice.
If a coupon has a minimum spend or category limit, check eligibility before relying on the final sale price.
Sale price and savings
The savings amount is how much money is removed from the original price. The sale price is what remains after the discount.
A 25 percent discount means you pay 75 percent of the original price before tax or other fees.
If tax, shipping or fees apply, the final checkout total may be higher than the discounted item price.
This is why cart totals can feel different from shelf math. The calculator explains the item discount, not every checkout line.
Stacked discount math
Savings = original price x discount percent / 100. Sale price = original price - savings.
For stacked discounts, apply the first discount, then apply the second discount to the new price.
For example, 30 percent off then 10 percent off is not the same as 40 percent off. The second discount is applied after the first reduction.
Two discounts in a row
For a 120 dollar item with 25 percent off, savings are 120 x 25 / 100, or 30 dollars. The sale price is 90 dollars.
For 30 percent off then 10 percent off, a 100 dollar item becomes 70 dollars after the first discount. The second discount takes 7 dollars off, leaving 63 dollars.
The effective discount is 37 percent, not 40 percent.
Coupons with limits
The most common mistake is adding stacked percentages directly. Two discounts can stack without being additive.
Another mistake is calculating the discount from the wrong base price. Make sure the original price is the price before the discount you are applying.
Also check whether a coupon applies before or after tax, shipping or other store promotions.
For subscriptions, check whether the discount applies to the first billing period only or repeats on renewal.
Discount Calculator FAQ
How do I calculate percent off?
Multiply the original price by the discount percent, then divide by 100. That gives the savings amount.
Subtract the savings from the original price to get the sale price.
For 20 percent off 50 dollars, the savings are 10 dollars and the sale price is 40 dollars.
Are stacked discounts added together?
Usually no. Stacked discounts are often applied one after another. The second discount applies to the already reduced price.
For 20 percent off then 10 percent off, a 100 dollar item becomes 80 dollars, then 72 dollars.
That is an effective 28 percent discount, not 30 percent.
What is the difference between sale price and savings?
Savings is the amount removed from the original price. Sale price is the amount you pay before any tax, shipping or fees.
If a 200 dollar item is 15 percent off, the savings are 30 dollars.
The sale price is 170 dollars.
How do I find the original price from a sale price?
If you know the sale price and discount percent, divide the sale price by the remaining percent.
For example, if an item is 80 dollars after 20 percent off, you paid 80 percent of the original price.
80 divided by 0.80 gives an original price of 100 dollars.
Does tax apply before or after discount?
Sales tax rules depend on location and the type of discount. Many checkout systems calculate tax after eligible discounts, but rules can vary.
The discount calculator shows the item discount math. It does not decide tax law or store policy.
For the final checkout amount, use the stores receipt or cart total.
