What you'll do with it
Forecast the lifetime value of one customer. Plug in pricing, churn, contract length, billing cycle, and cost of sales, and the model returns LTV, contribution margin, payback period, and breakeven on acquisition cost.
Built for the question that comes up at every stage: do my unit economics actually work? Pressure-test pricing, decide whether to spend on acquisition, sanity-check a SaaS or transactional business before scaling.

When to use this vs. other tools
Focused tool for unit economics only. If you need expenses, hiring, financial statements, and cap table on top, use the Standard Financial Model. If you're modeling ecommerce specifically, try the Ecommerce Forecasting Tool for cohort-based new-vs-repeat customer logic.
