Что такое KPI (Key Performance Indicator)?

A Key Performance Indicator is a specific, measurable value that demonstrates how effectively an organization is achieving a key business objective. Unlike general metrics — which track activity — KPIs are tied directly to strategic goals and serve as the primary diagnostic tool for business performance. The distinction matters: website visitors is a metric; customer acquisition cost is a KPI. Revenue is a metric; revenue growth rate relative to customer acquisition cost is a KPI.

Effective KPIs share several characteristics captured in the SMART framework: they are Specific (clearly defined), Measurable (quantifiable with reliable data), Achievable (realistic given resources), Relevant (directly linked to a strategic priority), and Time-bound (evaluated over a defined period). Organizations typically maintain a small number of top-level KPIs — often 3–7 — to avoid metric overload, supplemented by subsidiary metrics that feed into them.

KPIs vary by business function and stage. SaaS companies track ARR growth, churn rate, net dollar retention, and CAC payback period. E-commerce businesses focus on conversion rate, average order value, and return rate. Professional services firms track utilization rate, revenue per employee, and client retention. At the executive level, KPIs often ladder up to a single north star metric — the one number that best represents the value the business delivers to its customers.
