- Enter a realistic value for Current MRR and complete the remaining required fields.
- Check that Monthly Expansion Revenue uses the period and unit shown beside the input.
- Review the headline estimate together with the detailed figures; no single output should be interpreted in isolation.
- Change one assumption at a time to understand which variable has the greatest effect.

Status—
Adjusted MRR = Current MRR + Expansion revenue − Churn loss + Price increase impact. ARR = Adjusted MRR × 12.
The calculator applies this relationship consistently to the values entered above.
What the result means
The headline figure summarizes the modeled arr outcome under the current assumptions. The supporting rows separate important components so you can check whether the result is operationally or financially plausible.
Treat this as a planning estimate. Actual arr outcomes can differ because of timing, fees, taxes, rounding, eligibility rules, market conditions, or data quality that the simplified model does not capture.
Begin with the prefilled scenario: Current MRR = 45000; Monthly Expansion Revenue = 7000; Monthly Churn Loss = 3500; Monthly Price Increase Impact = 2500. Record the result, then change Current MRR while holding the other inputs constant.
The difference between the two outputs shows the sensitivity of arr to that assumption. Repeat with Monthly Expansion Revenue for a second comparison.
What does the ARR Calculator show?
It converts the entered Current MRR, Monthly Expansion Revenue, Monthly Churn Loss, Monthly Price Increase Impact assumptions into an indicative arr result and a supporting breakdown.
How should I choose a value for Current MRR?
Use a current, documented figure when available. For forecasts, test a conservative case alongside your expected value rather than relying on a single assumption.
Why does Monthly Expansion Revenue materially change the estimate?
Monthly Expansion Revenue is part of the model's scale or rate relationship. Even a modest adjustment can compound or flow through several displayed figures.
Can I use the result as a final decision?
No. Use it to screen scenarios and identify trade-offs, then confirm material startups & digital business decisions with source records and qualified advice where appropriate.
