What Is a KPI? The Few Numbers That Actually Matter
DICTIONARY · FUNDAMENTALS

What Is a KPI?

A KPI is a key performance indicator: a metric chosen because it tells you whether you are achieving something that matters.

In plain English

The word key is doing the work. A dashboard with thirty numbers has no KPIs; it has a data feed, and nobody looks at it twice.

A KPI has to be something a decision would hang on. If the number moved and nothing would change, it is a metric worth watching and not a KPI.

What to know

Few
Three to five. More than that and none get attention.
Tied to an outcome
Connected to revenue, retention or cost.
Actionable
Someone can influence it.
Leading and lagging
Some tell you what happened, some tell you what is coming.

Why it matters

The discipline is in the exclusion. Choosing five KPIs means deciding that everything else is context, which is what makes the five get looked at.

Common mistakes

×Too many KPIs, so none are watched.
×Choosing metrics that are easy to measure rather than meaningful.
×Vanity metrics like impressions and followers as headline numbers.
×No target attached, so the number cannot be judged.

FAQs

How many KPIs should a small business have?

Three to five. Usually enquiries, cost per customer, conversion rate and retention.

Are impressions a KPI?

Almost never. They measure delivery, not outcome.
