ARR growth rate
ARR growth rate is the year-over-year or period-over-period percentage change in ARR, how it is calculated, and its role in efficiency rules like Rule of 40. For ARR growth rate, the useful boundary is whether the movement comes from customers, contracts, billing, cash timing, or recognition rules.

Why it matters
Understanding ARR growth rate matters because revenue and customer metrics can change materially when teams mix contract, billing, cash, recognition, churn, or expansion logic. The definition protects the story from drifting. Pluvo decomposes ARR growth into new, expansion, and churn, so the rate is explained by its drivers.
In practice
Revenue example
Teams use ARR growth rate when they need to separate customer, contract, billing, recognition, and cash effects. That prevents a revenue movement from being misread as growth, churn, expansion, or timing noise.
Pluvo example
Pluvo decomposes ARR growth into new, expansion, and churn, so the rate is explained by its drivers.
In practice, teams should define ARR growth rate with a clear source, owner, time period, and decision before they use it in reporting, planning, or operating reviews.
