Ending MRR = ending subscribers × monthly price
Ending ARR run rate = ending MRR × 12

Questions about this tool
How is monthly recurring revenue projected?
Each month, the model applies churn to existing subscribers, adds the new subscribers you enter, and multiplies the resulting count by monthly price.
Does this include upgrades or downgrades?
No. It assumes one fixed monthly price and does not model plan changes or one-time charges.
Is ARR the same as recognized annual revenue?
No. ARR is the ending monthly recurring revenue multiplied by 12, not revenue recognized over the period.
Can the subscriber count be fractional?
The projection may show fractional expected subscribers because it represents a mathematical estimate.
