KPI Meaning and Plural
KPI means “key performance indicator,” a measure used to track progress or performance. Because the abbreviation is countable, “KPIs” is the regular plural when discussing more than one indicator.
KPI means “key performance indicator”; use “KPIs” for multiple indicators.
Key details
Important caveats
Plural Boundary
Cambridge examples use KPIs for multiple indicators, supporting the regular plural without an apostrophe.
Plural Boundary Extended
Use “KPIs” as the ordinary plural; an apostrophe is not needed merely to make the abbreviation plural.
Further guidance
Example
“The team tracks three KPIs: renewal rate, response time, and customer retention.” The plural form is used because three indicators are named.
Meaning
Cambridge defines KPI as an abbreviation for key performance indicator.
When To Use
Write out “key performance indicator” on first use when the audience may not know KPI, then use KPI for the singular and KPIs for more than one indicator.
