How this calculator works
MRR (Monthly Recurring Revenue) is the lifeblood metric of any subscription business. It's predictable, scalable, and what investors value most. ARR = MRR × 12. Net MRR growth = New MRR + Expansion MRR − Churn MRR − Contraction MRR. This calculator models your MRR trajectory based on current plans, growth, and churn.
MRR = Σ(Customers per plan × Plan price) | Net MRR growth = New MRR × growth rate − MRR × churn rate | ARR = MRR × 12
