What this calculator estimates
Calculate current and projected annual recurring revenue from monthly recurring revenue, annual contracts, expansion and recurring churn assumptions. It is designed for fast planning and comparison in the United States. The output is an estimate, not a binding quote, approval, tax determination, insurance offer or professional recommendation.
How to use it
Enter the requested values using a single consistent time period and currency. Select Calculate, review the headline result and supporting figures, then change one assumption at a time to compare another scenario.
How the calculation works
Monthly recurring revenue is annualized and combined with other annual recurring contracts. Entered expansion is added and recurring-revenue churn is subtracted.
Important limitations
Bookings, implementation fees, usage revenue, foreign exchange, contract start dates, downgrades and revenue-recognition rules are not fully modeled.
