Discount Calculator
Work out the final price and total savings from an original price and a discount percentage.
Enter the original price and a discount percentage, and this tool instantly shows how much money you save and what the final price will be after the discount is applied — useful for checking sale prices, comparing deals, or working out coupon savings before checkout.
Why percentage discounts can be misleading when compared directly
A 50% discount on a higher original price can easily save more money in absolute terms than a 70% discount on a much cheaper item, yet the bigger percentage number often feels like the better deal at a glance. Calculating the actual final price and savings amount, rather than just comparing percentage figures side by side, gives a much clearer picture of which specific deal is genuinely better for your actual spending.
How stacking multiple discounts actually works, and why it's not additive
Two discounts don't simply add together the way it might seem intuitive — a 20% discount followed by a further 10% off doesn't equal 30% off the original price, because the second discount applies to the already-reduced price, not the original one. Working through stacked discounts one at a time, using the resulting price from the first discount as the starting point for the second, gives the mathematically correct final result rather than an inflated one from simply adding percentages.
Why retailers frame discounts as percentages rather than fixed amounts
A percentage discount scales naturally across items of different prices without needing a separate fixed-dollar promotion for every price point, which is part of why 'X% off' is such a common promotional format across nearly every retail category. Understanding the actual dollar impact behind that percentage, though, is what actually determines whether a specific deal is worth taking.
How to use it

Common ways people use this tool
Checking a sale price before buying
Confirm the actual final price and savings amount for an item advertised with a percentage discount.
Comparing two different sale offers
Work out the true final price for two competing discount offers to see which one actually saves more money.
Calculating a coupon or promo code discount
Apply a known coupon percentage to a cart total to see the exact discounted amount before checking out.
Tips for getting the best results
- For stacked discounts, apply them one at a time in sequence rather than adding the percentages together.
- Compare the actual dollar amount saved between deals, not just the headline percentage, especially when original prices differ.
- Double-check whether a displayed discount applies before or after tax, since that can change the final price you actually pay.
- Watch for discounts advertised on an inflated 'original' price that may not reflect a genuine typical selling price.
Frequently asked questions
Can I calculate multiple stacked discounts?
This calculator applies a single discount at a time; for stacked discounts, apply the first, then use the resulting final price as the new original price for the second discount.
Does it work with any currency?
Yes — it works with plain numbers, so it's currency-agnostic; just use whichever currency your original price is in.
Can I work backwards from a final price to find the discount percentage?
This version calculates from original price and percentage; for backwards calculation, the Percentage Calculator tool's 'X is what % of Y' option can help.
Why doesn't a 20% discount plus a 10% discount equal 30% off?
Because the second discount is calculated against the already-reduced price from the first discount, not the original price, so the combined effect is mathematically slightly less than a straight 30% off the original.
Does this calculator include sales tax in the final price?
No, it calculates the discount purely against the price you enter; add tax separately afterward if it applies in your situation.
What's the difference between a discount and a markdown?
The terms are often used interchangeably in everyday language; the underlying calculation of savings and final price is the same regardless of which word a specific retailer uses.
Can I use this to calculate a tip or markup instead of a discount?
This tool is designed specifically for discounts (subtracting a percentage); for adding a percentage instead, like a tip or markup, the Percentage Calculator tool's 'X% of Y' option combined with simple addition would give the right result.
Why do some stores show a crossed-out 'original' price that seems unrealistically high?
This is sometimes referred to as 'anchoring' — showing a higher reference price can make the actual sale price feel like a bigger bargain by comparison, even if that original price wasn't a genuine typical selling price.
Does a bigger percentage discount always mean a better absolute deal?
Not necessarily — a smaller percentage off a higher-priced item can still save more actual money than a larger percentage off a cheaper item, which is exactly why checking the calculated dollar savings, not just the percentage, matters when comparing deals.
Can this calculator be used for calculating a price increase instead of a discount?
This tool is built specifically for subtracting a discount percentage; for a price increase, adding rather than subtracting the percentage amount would give the correct new price instead.
