“You can't manage what you don't measure.” Key performance indicators — KPIs — are the specific, measurable numbers a business tracks to see whether it's hitting its goals. They turn vague hopes into concrete targets a team can actually aim at.
What a KPI Is
A key performance indicator is a measurable value that shows how well a business is achieving an important objective. The word “key” matters — a business could measure a thousand things, but KPIs are the few numbers that actually reflect whether it's succeeding at what counts.
Examples of KPIs
KPIs vary by business and goal, but common ones include revenue growth, profit margin, customer retention rate, sales per employee, website conversion rate, average order value, and on-time delivery rate. A coffee shop might track daily sales and repeat customers; an app might track active users and subscription conversions.
What Makes a Good KPI
A good KPI is tied to a real goal, is measurable, and is actionable — meaning the business can actually do something in response to it. Beware “vanity metrics” that look impressive (like total social-media followers) but don't drive real decisions. The best KPIs tell you what to change.
Using KPIs to Manage
Businesses set target values for their KPIs, track them over time, and use the trends to spot problems early and decide what to adjust. In our worked case study, a fitness studio watched two KPIs — member retention and class capacity utilization — and used them to decide it should add classes and an app before opening a costly second location. KPIs turned a gut feeling into an evidence-based decision.
Leading vs. Lagging Indicators
Some KPIs are lagging — they report results after the fact, like last quarter's profit. Others are leading — they hint at future results, like the number of sales leads in the pipeline. Watching both lets a business see where it's been and where it's headed.
