What this calculator estimates
Calculate ending monthly recurring revenue, net MRR growth and an annualized projection from new, expansion, churned and contraction MRR.
How to use it
Enter Starting MRR ($); New customer MRR added ($); Expansion MRR added ($); Churned MRR lost ($); Downgrade MRR lost ($); Projection months at same net rate. Select Calculate to update the results.
How the calculation works
New and expansion MRR are added while churn and contraction are subtracted. Net change divided by starting MRR gives the period growth rate used for the optional compound projection.
Worked example: starting scenario
| Starting MRR ($) | 75000 |
|---|---|
| New customer MRR added ($) | 12000 |
| Expansion MRR added ($) | 5000 |
| Churned MRR lost ($) | 6500 |
| Downgrade MRR lost ($) | 1800 |
| Projection months at same net rate | 12 |
| Ending monthly recurring revenue | $83,700.00 |
|---|---|
| Net MRR change | $8,700.00 |
| Net MRR growth rate | 11.6% |
| Gross MRR added | $17,000.00 |
| Projected MRR after selected months | $279,918.50 |
Important limitations
Repeating one month of growth for a long projection can be unrealistic. Seasonality, cohorts, price changes and contract timing should be modeled separately.
