Discount Calculator
Find the final price after applying a percentage-off discount.
So funktioniert's
This calculator finds the final price after a percentage-off discount: savings = original price Ă (discount % Ă· 100), and final price = original price â savings. A $120 jacket at 25% off saves $30, bringing the final price to $90.
Stacking multiple discounts (like a storewide sale plus an extra coupon) doesn't add the percentages together the way it might seem to â each discount applies to the price after the previous one, not to the original price. "25% off, then an extra 10% off" on that $90 result gives a further $9 off, landing at $81 total â not the $96 you'd get from treating it as a flat 35% off the original $120.
This is why store promotions advertised as "stack these two discounts" are worth calculating explicitly rather than assuming: apply this calculator once per discount, feeding each result back in as the new starting price for the next one.
"Discount," "markdown," and "clearance" are often used loosely to mean the same thing â a reduced price â though retailers sometimes use "markdown" specifically for a permanent price reduction versus "discount" for a temporary promotional price. For this calculator's math, the distinction doesn't matter; the formula is identical either way.
When comparing two different deals â say, "$20 off" versus "15% off" on the same item â converting both to a final dollar price is the clearest way to see which is actually the better deal, since a flat dollar discount and a percentage discount only favor different options depending on the item's original price.
Retail pricing psychology often relies on discount framing to feel more compelling than the raw math suggests â a price ending in ".99" or a "was $100, now $79" comparison price both nudge perception of value, independent of whether the actual discount percentage is particularly large. Running the numbers through this calculator strips that framing away and shows the plain final price.
Can I stack multiple discounts?
Apply this calculator once per discount, using the previous result as the new starting price.
Why do prices often end in .99 instead of a round number?
It's a pricing psychology tactic â a price like $19.99 is perceived as meaningfully cheaper than $20 even though the actual difference is a single cent, since shoppers tend to focus on the leftmost digit.
Does stacking two 10% discounts equal 20% off?
No â the second 10% applies to the already-discounted price, so two stacked 10% discounts actually total 19% off the original price, not 20%.
What's the difference between a discount and a markdown?
They're often used interchangeably; when retailers distinguish them, "markdown" usually refers to a permanent price cut, while "discount" implies a temporary promotional reduction. The math is identical either way.
How do I compare a percentage-off deal to a flat dollar-off deal?
Calculate the actual final price for both using this calculator, then compare the two final prices directly â that removes any ambiguity about which discount format is worth more on a specific item.
How do I find the original price from a discounted price?
Divide the discounted price by (1 â discount rate as a decimal). If $75 is the price after a 25% discount, the original price was 75 Ă· 0.75 = $100.
Does this calculator account for sales tax?
No â it calculates the discount only. Apply the Sales Tax Calculator to the discounted price afterward if you need the final tax-inclusive total.
What does "percentage off" actually mean mathematically?
It means the savings equal that percentage of the original price â "30% off" means you save 30% of the price and pay the remaining 70%.
Can a discount ever be more than 100%?
No â a 100% discount means the item is free; anything beyond that isn't a meaningful discount calculation.
Why does percentage order matter when stacking discounts?
It doesn't, mathematically â applying 20% then 10% gives the same final result as 10% then 20% â but each must be calculated on the running discounted price, not the original, for either order to give the correct answer.
