About the Free Discount Calculator
A percentage-off discount is simple in isolation, but two things trip people up in practice: stacked discounts don't add together the way they look like they should, and "25% off" reads very differently once you see the actual dollar amount saved versus what you're still paying. This calculator turns a percentage discount into the real numbers — what you save, what you pay, and what the final price is once sales tax is added back on top of the discounted price.
It's used mid-shop, comparing a flat percentage discount against a competing offer, checking a cashier's math on a marked-down item, or figuring out whether a "30% off" sale is actually a better deal than a smaller discount on an already-cheaper item elsewhere.
What you're buying and what you're paying for it stay on your device — the discount math runs entirely in your browser, with nothing about your shopping sent anywhere or logged.
How it’s calculated
One thing worth knowing before combining coupons: stacked percentage discounts don't add together. Two discounts of 25% and 10% don't total 35% off — the second discount applies to the already-discounted price, so the combined savings is actually 32.5% off the original. Each discount multiplies the remaining price rather than subtracting from the original percentage.
Frequently asked questions
If I have two discounts, do they just add together?
No — each discount applies to the price after the previous one, not to the original price, so two 25% and 10% discounts combine to about 32.5% off total, not 35%. Apply them one at a time to see the real final price.
Is a percentage-off discount or a flat dollar-off discount usually the better deal?
It depends entirely on the original price — a percentage discount saves more on expensive items, while a flat dollar amount saves more on cheap ones. Compare the actual dollar savings, not just which number looks bigger.
How do I figure out the original price if I only know the sale price and discount percentage?
Divide the sale price by (1 minus the discount as a decimal) — a $60 sale price after a 25% discount means the original price was $60 ÷ 0.75 = $80.
Does sales tax get calculated on the original price or the discounted price?
Almost always on the discounted price — tax is charged on what you actually pay, not the pre-discount sticker price, which is why this calculator applies tax after the discount is subtracted.
What counts as a genuinely good discount versus a marketing gimmick?
There's no universal threshold, but a discount off an artificially inflated "original" price isn't a real deal — compare the sale price to what the item has actually sold for recently elsewhere, not just the percentage claimed on the tag.
