Discount amount = Original price × Discount rate
Final price = Original price − Discount amountThe calculation uses the price, revenue, cost, rate or quantity fields shown by the tool. Gross and net figures are not interchangeable, and taxes, overhead, returns, discounts or financing should be included only in the field intended for them.
Discount Calculator: calculate Sale price, Discount amount, Original price Enter either the original price and discount percentage, or the sale price and discount percentage, and calculate either how much discount in currency, or what the price was. It uses a simple percent calc in shopping, pricing and sale situations, for budgets or to learn math.
Make sure the discount is entered as a percentage. For example, enter 25% rather than entering 0.25 unless the calculator specifically requests a decimal.
Discount Description There may be several types of discount with a given original price, such as percentages, fraction, etc. When working with percentages and fractions to determine the discount amount, use original price * discount%. To determine final price (actual product prices), original price - discount amount.
For example, a $100 item with a 20% discount has a $20 discount, leaving a final price of $80.
The discount amount is calculated using:
Discount Amount = Original Price × Discount Rate
When the discount is entered as a percentage, convert it to a decimal first:
Discount Rate = Discount Percentage ÷ 100
The final discounted price is:
Sale Price = Original Price − Discount Amount
An equivalent formula for the final price is:
Sale Price = Original Price × (1 − Discount Rate)
Suppose a jacket has an original price of $120 and is discounted by 25%.
Step 1: Convert the percentage to a decimal.
25% ÷ 100 = 0.25
Step 2: Calculate the discount amount.
$120 × 0.25 = $30
Step 3: Subtract the discount from the original price.
$120 − $30 = $90
Discount amount: $30
Final price: $90
The customer saves $30 and pays $90 before any applicable taxes, shipping charges, or other fees.
Consider an item originally priced at $75 with a 15% discount.
Discount Amount = $75 × 0.15 = $11.25
Sale Price = $75 − $11.25 = $63.75
The discount is $11.25, and the discounted price is $63.75.
| Original Price | Discount | Discount Amount | Final Price |
|---|---|---|---|
| $50 | 10% | $5 | $45 |
| $50 | 20% | $10 | $40 |
| $50 | 25% | $12.50 | $37.50 |
| $100 | 10% | $10 | $90 |
| $100 | 20% | $20 | $80 |
| $100 | 30% | $30 | $70 |
| $200 | 15% | $30 | $170 |
| $200 | 25% | $50 | $150 |
| $500 | 20% | $100 | $400 |
| $1,000 | 30% | $300 | $700 |
The discount amount and final price are different results. The discount amount tells you how much money is removed from the original price, while the final price tells you how much remains after applying the discount.
For example, a 20% discount on $250 produces a $50 discount and a $200 final price.
Price values quoted in dollar and cents typically will be rounded to the nearest cent to yield a monetary result. Decimals may be included at intermediate steps prior to finalizing the calculation and rounding it to nearest cent.
A percentage based off a final price. When I get a $20 discount it’s always going to be a $20 discount, a 20% discount will vary with the price it’s associated with.
For example:
This is why the original price must be known before calculating a percentage discount.
Two discounts applied one after another are generally not the same as adding the two percentages together.
For example, suppose an item costs $100 and receives a 20% discount followed by a 10% discount.
First discount: $100 × 0.20 = $20
Price after first discount: $100 − $20 = $80
Second discount: $80 × 0.10 = $8
Final price: $80 − $8 = $72
The combined reduction is $28, which represents an effective discount of 28%, not 30%, because the second discount is applied to the already discounted price.
Use a Calculator as a tool to determine Sale Prices, Promotions, Coupon Codes, Markdowns, eCommerce prices, business…
Multiply the original amount by the discount expressed as a decimal number; you should then take the result away from the original amount to come up with a sale price
A 20% discount on $100 is $20. The final price is $80.
Multiply the old price by 0.10 to get your discount and then subtract that number from the old price.
Use Sale Price = Original Price × (1 − Discount Rate). For a 25% discount, multiply the original price by 0.75.
No. If you have two 20% off coupons, the second is applied after the first has already reduced the price. By applying 20% off twice consecutively, your discount is actually 36% off rather than 40%.
Not necessarily. The amount of discount shown typically affects the price shown by the seller and taxes and fees calculated per transaction may apply.
Enter a realistic current case, calculate the result, then raise the cost or lower the selling price. The comparison shows how sensitive the margin, break-even point, tax amount or total cost is to that change.
If you know the original price (i.e. the price without discount) and the amount saved, then you can find the percentage discount. This is given by29.
Discount Percentage = (Discount Amount ÷ Original Price) × 100
For example, if an item originally costs $200 and you save $30:
($30 ÷ $200) × 100 = 15%
The discount is therefore 15%.
If you know the discounted price and the discount percentage, you can work backward to find the original price.
Original Price = Sale Price ÷ (1 − Discount Rate)
For example, if an item costs $72 after a 20% discount:
$72 ÷ (1 − 0.20) = $72 ÷ 0.80 = $90
The original price was $90, and the discount amount was $18.
Markup or a percentage discount: A price increase to establish the selling price to a price reduce from one that there had an initially a value reduction to reduce the selling price from that they begin.
| Calculation | Basic Formula |
|---|---|
| Discount Amount | Original Price × Discount Rate |
| Discounted Price | Original Price × (1 − Discount Rate) |
| Markup Amount | Cost × Markup Rate |
| Price After Markup | Cost × (1 + Markup Rate) |
A 20% discount and a 20% markup are therefore not inverse operations. It is therefore the case that if there is a 20% discount applied after a 20% markup, we do not have returning to the original price.
For ecommerce pricing, the Discount Calculator can be used to estimate the customer-facing price of a promotion. Using the normal selling price, insert the promotion percentage to find the markdown.
For example, a $64 product advertised at 15% off has a discount of $9.60 and a discounted price of $54.40.
When promoting something for your business, do not mistake a product sold at a discounted rate with profit. With added product cost, shipping, fees for payment processing, marketing expenses, and other costs that might arise such as returns or any other expenses or tax.
There is a separate calculation for the discount and the sales tax. Here’s a common example for pricing the discount is first calculated on the qualifying amount, and sales tax is calculated afterwards based on the rules of that particular transaction.
Let's say, for instance, the cost of an item is $100 and there is a 20% discount. That item would then have a cost of $80. When an estimated 8% sales tax were to be applied to that $80!
$80 × 0.08 = $6.40 tax
$80 + $6.40 = $86.40 total
Because the way tax is dealt with varies according to the transaction and country this example must not be taken as a global tax principle.
Some offers are only redeemable when purchase exceeds a threshold (in that case calculate first if purchase is applicable with promo prior to discount %).
For instance, a promotion for 20% off all $100 or more purchases would not, for instance, be automatically applied to a $90 purchase, which the calculator can do the percentage arithmetic for but it would not be able to see whether or not a given retailer's promotional scenario was available without us specifying it.
Currency calculations, for the most part, are usually show to two places past the decimal point. So, a $12.345 calculation discount could be represented as $12.35 by applying a to two places round to it.
The way your shopper's or client's software rounds totals can differ: Some round the total of each item line, other first add up all line extensions or use a calculated whole before rounding.
A 0% discount produces no reduction, so the sale price equals the original price.
A 100% discount produces a zero price in the basic mathematical model:
Original Price × (1 − 1) = $0
Real-world promotions may impose additional restrictions, limits, minimum purchases, or exclusions, so the mathematical result does not necessarily represent the terms of an actual promotion.
A negative discount percentage should not be understood as a common discount. In mathematical calculation, the price to be obtained is rather larger than higher compared to decrease, if you use a minus-percentage. You probably rather would look for the function "plus-price (in %)".
| Discount | Price You Pay |
|---|---|
| 5% off | 95% of original price |
| 10% off | 90% of original price |
| 15% off | 85% of original price |
| 20% off | 80% of original price |
| 25% off | 75% of original price |
| 30% off | 70% of original price |
| 40% off | 60% of original price |
| 50% off | 50% of original price |
| 75% off | 25% of original price |
There’s an informal mental shorthand. “30% off,” for example, means you pay “70 percent” of the price.
