A key performance indicator (KPI) is a measurable value that tracks how effectively a person, team, or organization is achieving specific business objectives. KPIs help align activities with goals, monitor progress, and guide decision-making based on real performance data.

Common examples of KPIs in sales are:

• Revenue growth
• Lead-to-close rate
• Customer acquisition cost (CAC)
• Average deal size
• Sales cycle length
• Quota attainment
• Churn rate

KPIs provide focus, accountability, and clarity. When chosen carefully, they help teams prioritize the right actions, identify problems early, and continuously improve performance. The best KPIs are specific, actionable, and aligned with broader business goals.
