Don’t know your MRR? Build it from your plans
Add a row per pricing plan. Annual plans are automatically converted to a monthly-equivalent before they’re added in — a common source of hand-calculated MRR being wrong.
How do you calculate ARR from MRR?
Multiply MRR by 12: ARR = MRR × 12. This assumes revenue stays roughly flat over the next 12 months — it's a run-rate projection, not a forecast that accounts for growth or churn.
How do you calculate MRR from ARR?
Divide ARR by 12: MRR = ARR ÷ 12.
What's the difference between MRR and ARR?
MRR (monthly recurring revenue) is your predictable revenue over one month. ARR (annual recurring revenue) is the same figure annualized — MRR × 12. Neither includes one-time payments, setup fees, or non-recurring revenue.
How do I calculate MRR if some customers pay annually?
Convert each annual plan to its monthly-equivalent by dividing the annual price by 12, then add it to your monthly plans. Adding a customer's full annual payment directly into MRR without normalizing it first is one of the most common ways founders miscalculate their own MRR.
Does ARR include one-time or non-recurring revenue?
No. ARR should only include predictable, recurring subscription revenue. Setup fees, one-time purchases, and usage-based overage charges are typically excluded since they aren't guaranteed to repeat.
