What does the Discount Calculator compute?

It takes an original price plus a discount percent (or a known sale price) and returns the sale price, the percent off, and the amount you save.

Can the Discount Calculator work backward from a sale price?

Yes. Switch to "By sale price," enter the original price and the price you actually paid, and it derives the effective discount percent for you.

How does the Discount Calculator handle a stacked second discount?

An optional extra discount percent is applied to the already-discounted price, not the original price, which matches how "extra X% off" clearance sales are usually calculated.

Does the Discount Calculator include sales tax in the sale price?

No. It calculates the markdown only. Use the Sales Tax Calculator afterward if you also need the tax added to your final total.

Is the Discount Calculator's result financial advice?

No. It gives estimates only and is not financial or tax advice — always confirm the final price at checkout, especially with tax, fees, or store-specific rounding rules.

Does the Discount Calculator upload my prices anywhere?

No. Every calculation happens locally in your browser; the prices and percentages you type are never sent to ArrayKit or anywhere else.

About Discount Calculator

Discount Calculator finds the sale price, the percent off, and the amount you save from an original price and a discount. Enter the original price plus a discount percent to see the sale price and savings instantly, or switch to "By sale price" and enter a known final price to work backward and find the percent off. Add an optional second, stacked discount — like an extra 10% off already-marked-down items — and the calculator applies it to the reduced price, the way real markdown sales stack. It is useful for shoppers comparing deals, retailers pricing a sale, and anyone checking a coupon or clearance markdown before checkout. Every calculation runs locally on your device, and these figures are estimates only, not financial or tax advice.

Common errors & troubleshooting

Entering the discount as a decimal, like 0.25, instead of a percent. — Type the discount as a whole percent — 25 for 25% off, not 0.25 — the Discount Calculator expects a percent value.
Sale price entered is higher than the original price. — In "By sale price" mode the final price must be between 0 and the original price; a markdown can't raise the price.
A stacked "extra 10% off" gets applied to the original price instead of the already-discounted price. — The Discount Calculator's second discount field applies to the reduced sale price automatically, matching how real stacked markdowns work — no manual re-entry needed.
Result looks off because sales tax was expected to be included. — The Discount Calculator computes the markdown only; add sales tax separately with the Sales Tax Calculator if you need the final checkout total.
