Table 220 Aug 2026From “Net revenue retention is a cohort definition”

The NRR comparability audit

A percentage earns comparison only after its construction survives the same six questions.

Table 2The NRR comparability audit

Check	Yes means	No means
Same cohort rule	The starting populations are constructed the same way	The percentages are not directly comparable
Same revenue basis	Both measures use the same recurring revenue concept	Explain the boundary before comparing
Same window	The periods have the same length and timing	Seasonality may be part of the difference
Same currency treatment	Foreign exchange is handled consistently	Separate price, usage and currency effects
Same definition over time	The series has a stable meaning	Mark a break or restate the history
Same segment mix	The populations have a comparable distribution	Interpret the result as portfolio composition
