KPI (Key performance indicator)
A key performance indicator (KPI) is a measure you track to understand how a business, team, or process is performing against an important goal.
A key performance indicator (KPI) is a measurable value that shows how effectively you are meeting a goal. It is a signal to monitor over time, such as a SaaS company's monthly recurring revenue, trial-to-paid conversion, or support response time. A useful KPI has a clear definition, an owner, and a reporting period; otherwise two people can read the same dashboard and reach different conclusions.
Choose a measure that can change a decision
Start with the outcome you care about, then choose the smallest set of measures that tells you whether it is moving. A customer-success team might track renewals due this quarter, gross revenue retention, and the share of accounts with a recent product use. A product team might watch activation rate alongside a longer-term retention measure. These are examples, not universal targets: the right KPI depends on the business model, customer, and stage.
KPI vs. OKR
A KPI monitors ongoing performance or the health of an existing process. An OKR (Objectives and Key Results) sets a time-bound direction for change and uses measurable key results to show progress. A KPI can become a key result when a team sets a target for improving it. For example, tracking weekly activated accounts is a KPI; increasing that count from 80 to 110 by the end of a quarter could be a key result.
Common mistakes
- Tracking numbers that look impressive but do not affect a decision.
- Changing the definition or denominator without documenting it.
- Using a target without checking data quality or unintended incentives.
- Calling every metric a KPI. Keep the list short enough that the team can review it regularly.
For a small SaaS, start with one business outcome and a few measures that explain it. Review them on a steady cadence, and change the set when the strategy or customer behavior changes.
