What this calculator estimates
Calculate current and projected annual recurring revenue from monthly recurring revenue, annual contracts, expansion and recurring churn assumptions.
How to use it
Enter Current monthly recurring revenue ($); Additional annual recurring contract revenue ($); Expected annual expansion rate (%); Expected annual recurring-revenue churn (%). Select Calculate to update the results.
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.
Worked example: starting scenario
| Current monthly recurring revenue ($) | 85000 |
|---|---|
| Additional annual recurring contract revenue ($) | 180000 |
| Expected annual expansion rate (%) | 18 |
| Expected annual recurring-revenue churn (%) | 10 |
| Projected annual recurring revenue | $1,296,000.00 |
|---|---|
| Current annualized MRR | $1,020,000.00 |
| Current total ARR before growth | $1,200,000.00 |
| Expansion revenue | $216,000.00 |
| Churned recurring revenue | $120,000.00 |
Important limitations
Bookings, implementation fees, usage revenue, foreign exchange, contract start dates, downgrades and revenue-recognition rules are not fully modeled.
Keep annual contracts out of MRR when adding them separately
Monthly recurring revenue is annualized by multiplying by 12. The additional annual-contract field is then added, so do not also include those same contracts in MRR. Expansion and churn are hypothetical percentages applied to that combined base. For $10,000 MRR and $20,000 genuinely additional annual contracts, current annualized recurring revenue is $140,000. The resulting projected ARR is a scenario run rate rather than recognized revenue or cash collections.
