DiscountVibe does one thing — as a discount calculator 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. 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. What follows concerns only that tool and the inputs involved in it.

Practically, all the calculation needs is the prices and percentages you enter. Typical reasons people open DiscountVibe include working back to the original price from a sale tag, and in every case the work happens on the visitor's own device rather than ours.

The nature of this site

The content on discountvibe.com exists to inform and educate. Every result is an estimate derived from your input, not a measurement or a piece of professional advice — and DiscountVibe makes no claim beyond that.

Everyday tools

DiscountVibe gives a quick, general answer. For anything with a consequence — a measurement that gets built from, a number that gets filed — verify the result independently.

Advertising

Advertising keeps the Site free. Advertisers have no influence over any result, and the presence of an advertisement is not an endorsement.

Provided without warranty

On DiscountVibe the key assumption is that you entered a case the method covers. 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. Within that we choose the method and inputs carefully; outside it, and wherever rounding, unit handling or browser quirks intrude, the Site comes with no warranty.
