Annualized recurring revenue baseline
This converts the current monthly recurring revenue base into an annualized run rate. The output is useful for scale context, but actual annual revenue can change if churn, expansion, pricing, collections, or new sales move differently than expected.
Assumption quality check
- The calculation assumes the current recurring base remains active for run-rate context.
- Exclude one-time fees unless they truly recur as subscription revenue.
Formula used
ARR run rate = Current MRR x 12
ARR run rate
Current MRR x 12
Quarterly run rate
Current MRR x 3

A single metric is useful, but SaaS planning works best when revenue, churn, acquisition efficiency, and capital efficiency are reviewed together.
