MRR to ARR Calculator
MRR to ARR Calculator multiplies monthly recurring revenue by twelve. It is an annualized run rate, not a forecast of recognized annual revenue. The formula assumes the entered month repeats unchanged and does not model churn, expansion, contraction, seasonality, future bookings, refunds, usage variation, or accounting recognition.

Annualized recurring revenue is 120,000.
Formula: 10,000 × 12 = 120,000
ARR annualizes the current monthly recurring run rate
In this simple convention, ARR = MRR × 12. MRR should include recurring revenue normalized to one month under a documented policy and exclude one-time services and setup charges.
How it works
Enter one consistently calculated MRR figure. Label the output annualized run rate and avoid presenting it as guaranteed future or GAAP/IFRS revenue.
Key concepts
Run rate freezes one moment
The calculation imagines the current month repeated twelve times.
Metric policy matters
Contracts, discounts, usage, trials, and annual prepayments require consistent normalization.
When to use it
- Annualize a stable MRR snapshot.
- Check a reported MRR-to-ARR multiplication.
- Compare recurring-revenue scale under one policy.
When not to use it
- Do not include one-time revenue in MRR.
- Do not call ARR a cash-flow or recognized-revenue forecast.
- Do not ignore churn and expansion when planning actual future revenue.
Worked examples
Basic annualization
- Input
MRR 10,000- Expected output
ARR 120,000
Twelve identical months are assumed.
One-time setup fee
- Input
MRR 10,000 plus 5,000 setup fee- Expected output
ARR remains 120,000 under recurring-only policy
One-time revenue is excluded.
Rapid churn
- Input
Current MRR 10,000 then customers cancel- Expected output
Actual next-year revenue below run rate
ARR is not a forecast.
Common mistakes
Including one-time fees
The metric stops representing recurring revenue. Correction: Apply a documented recurring-only policy.
Calling ARR booked or recognized revenue
Accounting timing can differ. Correction: Label it annualized recurring run rate.
Forecasting without churn
The current snapshot may not persist. Correction: Build a separate cohort or revenue forecast.
Best practices
- Document the MRR policy.
- Reconcile metric changes to new, expansion, contraction, and churn MRR.
- Keep run-rate metrics separate from financial statements.

Frequently asked questions
What is the MRR-to-ARR formula?
MRR × 12.
Is ARR a revenue forecast?
No. It annualizes the current recurring run rate.
Should setup fees be included?
Not in a recurring-only MRR policy.
Does ARR account for churn?
No. Churn requires a separate forward model.
