95-5 Rule
01 Definition
95-5 Rule meaning: The idea that about 95% of business buyers are not ready to buy now, and only 5% are.
The 95-5 rule suggests that at any moment roughly 95% of potential buyers are not in the market, while about 5% are ready to buy. Popularized by the Ehrenberg-Bass Institute and LinkedIn's B2B Institute, it argues brands should build memory with future buyers, not only chase in-market demand.
Why it matters
How 95-5 Rule fits the work
It reframes advertising as a long game: most of your audience will buy later, so staying memorable now shapes who they consider when they finally enter the market.
In context
A software firm accepts that most viewers will not sign up today and runs brand ads so buyers remember it when their contracts come up for renewal next year.
Practical note
The 95-5 split is a rough illustration, not a measured constant for every category; actual in-market rates vary by purchase cycle, so treat the ratio as a guide.
