Explore SaaS Metrics calculators and related business decision models on Martzine.
SaaS Metrics collects closely related calculations so you can move between specific models without returning to the top-level library.
These pages cover narrower SaaS Metrics questions and are intended to be opened when the standard calculator is not specific enough for the task.
Use the individual page for the formula, working inputs, examples, limitations and related long tail explanations.
Open the calculator that matches the decision you are reviewing. Focused sub-calculators are included where the broader model has a recurring narrower question.
ARR uses monthly recurring revenue.
Monthly Churn Rate uses customers lost, customers at start.
MRR uses new mrr, expansion mrr, contraction mrr.
Net revenue retention includes expansion and subtracts contraction and churn from the starting cohort.
SaaS Churn Rate uses customers lost, customers at period start.
Measure the change in MRR (monthly recurring revenue) between two observations. Keep one-time revenue outside both values.
SaaS LTV:CAC uses saas ltv, cac.
Tell us what you are trying to build, what problem you are solving and where the digital part becomes difficult. Martzine is built around that gap. Start with the outcome and the constraint, then work back to the right digital layer.
