Frequently Asked Questions
How do I calculate a discounted price?
Multiply the original price by the discount percentage, then subtract that amount from the original price. For example, a $100 item with a 20% discount saves $20, for a final price of $80.
How do I calculate the percentage discount from two prices?
Subtract the sale price from the original price, divide by the original price, then multiply by 100 to get the discount percentage.
Can this calculate stacked or multiple discounts?
Multiple discounts are typically applied sequentially, not added together — for example, 20% off followed by an additional 10% off is not the same as a flat 30% discount, since the second discount applies to the already-reduced price.
Is this tool free to use?
Yes, completely free with no signup, no limits and no software to install.
Is my data saved anywhere?
No — calculations run in your browser and the values you enter are not stored or sent to a server.
Does this include sales tax in the calculation?
This tool calculates the discount itself — if tax applies, it's typically calculated separately on the discounted price, depending on local tax rules about whether tax applies before or after discounts.
How much do I save with a 25% off coupon on a $60 item?
25% of $60 is $15, so you'd save $15, bringing the final price to $45.
Is this useful for calculating markup instead of discount?
Discount and markup are different calculations — a dedicated margin/markup calculator is more appropriate if you're calculating price increases from cost rather than reductions from list price.
Can I calculate the original price from a discounted price?
Yes — if you know the sale price and discount percentage, you can work backward to find the original price by dividing the sale price by (1 minus the discount as a decimal).
Is this useful for comparing deals between different stores?
Yes — quickly calculating the actual dollar savings and final price helps compare discount offers that may be presented differently (percentage off vs. dollar amount off) across retailers.
The Discount Calculator works out the sale price and amount saved for any percentage discount. Enter the original price and the discount percentage to see the final price instantly.
Percentage Off vs. Fixed-Dollar Off: Which Actually Saves More
A percentage discount and a fixed-dollar discount only save the same amount at one specific price point — above or below that point, one is always better than the other. A "$20 off" deal saves more than "10% off" on anything priced under $200, but 10% off wins on anything above $200. When comparing two different discount structures, calculate the actual dollar savings for your specific purchase amount rather than assuming the bigger-sounding number is the better deal.
Stacked Discounts: Why the Math Isn't Additive
When two discounts apply to the same purchase (a storewide sale plus a coupon code), each discount applies sequentially to the already-reduced price, not to the original price. A 20% discount followed by an additional 10% off does not equal 30% off the original price — the second 10% is calculated on the already-discounted amount, so the combined discount is always smaller than simply adding the two percentages together.
Watch for Inflated "Original" Prices
A discount is only meaningful relative to a genuine original price. Some retailers inflate a listed "original" price specifically to make a subsequent discount look larger than the actual savings, a practice regulated in some jurisdictions but not universally enforced. Checking a product's price history (via a browser extension or a price-tracking site) before trusting a big discount percentage is a reasonable way to confirm whether a "sale" price reflects a genuine reduction from a price the item was actually sold at.
Using Discount Math for Pricing Your Own Products
If you're setting a discount rather than receiving one, work backward from your actual margin: a percentage discount that looks appealing to customers can eliminate your entire profit margin if you haven't calculated exactly how much of your markup the discount consumes. Always calculate the discounted price against your cost basis, not just your listed price, before committing to a promotional discount percentage.
