Calculate sale prices, discount amounts, and total savings instantly. Supports stacked discounts, tax after discount, tip splitting, comparison, and finding the original price.
Enter your price and discount to see your savings.
A discount calculator is a utility tool that helps you quickly determine the final price of an item after a discount has been applied. Instead of doing the arithmetic manually, you simply enter the original price and the discount percentage, and the calculator instantly shows you the sale price, the amount you save, and the effective discount percentage.
Our Discount Calculator goes beyond a simple price-reduction tool. It supports stacked discounts, reverse discount calculations, finding original prices, discount + tax, discount + tip splitting, comparison shopping, and target price planning — making it useful for shoppers, business owners, marketers, and students alike.
To calculate a discount amount and final price:
To find the original price before discount:
⚠️ Common Misconception: Stacked discounts are NOT simply added together.
When a retailer applies a 20% discount followed by an additional 10% discount, the effective total is not 30%. The second discount is applied to the already-reduced price.
When an item is both discounted and subject to sales tax, the tax is almost always calculated after the discount has been applied, not before. This benefits the buyer because the taxable amount is smaller.
A discount is a reduction applied to the original price of a product or service. It is usually expressed as a percentage (like 20% off) or a fixed amount (like $10 off), which lowers the final amount you have to pay.
To calculate 20% off, multiply the original price by 0.20 to find the discount amount, and subtract that from the original price. A faster way is to multiply the original price by 0.80 (since you are paying 80% of the price) to immediately get the final sale price.
The formula is: Discount Amount = Original Price × (Discount Percentage ÷ 100). To find the final price, the formula is: Sale Price = Original Price − Discount Amount.
You can calculate the sale price by subtracting the discount amount from the original price. For example, if a $50 shirt has a $10 discount, the sale price is $50 - $10 = $40.
To find the original price before a discount, divide the sale price by (1 minus the discount percentage expressed as a decimal). Formula: Original Price = Sale Price ÷ (1 - Discount%). For example, an $80 sale price at 20% off is $80 ÷ 0.80 = $100 original price.
Stacked discounts apply one after another. The first discount is taken off the original price, and the second discount is taken off the new, already reduced price. They are not simply added together.
No, a 20% discount followed by another 20% discount does not equal 40% off. Because the second discount applies to the newly reduced price, the effective total discount is actually 36% off.
Typically, you calculate the discount first to find the sale price, and then apply the sales tax percentage to that sale price. Your final cost is the Sale Price plus the Tax Amount.
Standard tipping etiquette dictates you should calculate your tip based on the original bill amount before the discount was applied, as the waitstaff still provided service for the full value of the meal.
Subtract the sale price from the original price to find the savings amount. Then, divide the savings by the original price and multiply by 100. Formula: (Savings ÷ Original Price) × 100.
If you know the final price and the original price, you can find the discount backwards. Simply divide the sale price by the original price. Subtract that result from 1, and multiply by 100 to get the discount percentage.
The discount amount is the money you keep in your pocket (your savings). The sale price is the final amount of money you actually hand over to the cashier or store.
To compare two discounts, calculate the final sale price for both options. The option with the lower final sale price is the better deal, regardless of which discount percentage looks higher initially.
Your savings is the exact dollar amount that is deducted from the original price. You calculate it by multiplying the original price by the discount percentage (as a decimal).
Subtract your target price from the original price to find the required savings. Then, divide those savings by the original price and multiply by 100 to get the required discount percentage.
