Turn a month of revenue, customer, churn, margin, and acquisition inputs into a compact operating view.
Every output is calculated from your inputs. LTV, CAC payback, and LTV:CAC are planning proxies, not a valuation or a guarantee of future performance.

Formula notes
Ending MRR = starting MRR + new MRR + expansion MRR − churned MRR. NRR excludes new customers: (starting MRR − churned MRR + expansion MRR) ÷ starting MRR. The LTV proxy uses ARPA × gross margin ÷ monthly logo churn, so it is most useful when churn and margin are stable enough to be meaningful.
If you are evaluating a price change, run the subscription price-increase churn scenario alongside this page.
