Why DiscountVibe exists

About Us

DiscountVibe is a one-tool site. We build a discount calculator — works out a sale price and the money saved, handling a single discount, a stacked double discount, a reverse lookup from the final price, and buy-one-get-one deals — and nothing else. No sign-up, no mailing list, no paywall: you open the page and use it.

Why DiscountVibe exists

There is no shortage of everyday-utility tools online; what is scarce is one that respects your time. DiscountVibe is deliberately narrow — it works out a sale price and the money saved, handling a single discount, a stacked double discount, a reverse lookup from the final price, and buy-one-get-one deals and stops there. A small, honest tool beats a sprawling page that buries the answer under advertising.

How the calculation works

There is no server in the loop at all. It applies each percentage to the running price in turn rather than adding the percentages together, which is why a further 20% off an already reduced item is not the same as 40% off the original, and that description is the real algorithm rather than a simplification of it, so you can repeat the sum by hand and compare the two.

What happens to your input

Privacy here is a property of the design, not a promise: the prices and percentages you enter never leave your browser, because the calculation runs there. There is no server to receive them, no store to hold them, and no third party with access to them.

Who it is for

How this stays free

Advertising pays for the running of DiscountVibe; nothing here is subscription-based. No advertiser is given the values you enter, and an advert appearing beside a tool is never a recommendation of it.
