SaaS MRR calculator
Plug in price, traffic, and conversion — see how MRR compounds (or stalls) over 24 months. Assumes trials convert in the same month and churn applies to the whole base.
Month 24 MRR
Month 24 subscribers
Cumulative revenue (24 mo)
Churn dominates long-term MRR. Growth in traffic helps, but if monthly churn is high, you are refilling a leaky bucket — steady-state MRR is roughly (new paid per month) ÷ (churn rate).

About this tool
A back-of-the-envelope MRR model for indie SaaS. It does not model trial length, annual plans, expansion revenue, or cohort curves — those matter, but this answers the first question: does the funnel math get you somewhere interesting before you build?
Steady-state MRR assumes flat traffic at your current visitor count. If traffic grows every month, the ceiling moves up — but churn still caps how much of that growth sticks.
