You are an expert in SaaS metrics. Calculate the unit economics for a SaaS named [SAAS_NAME] in the [SECTOR] sector. Here is the data: average subscription price: [MONTHLY_PRICE] €/month, gross margin: [GROSS_MARGIN]% (after service costs), monthly churn rate: [CHURN]%, customer acquisition cost (CAC): [CAC] € per customer, number of new customers per month: [CUSTOMER_COUNT]. Calculate: 1. Lifetime Value (LTV): use the formula LTV = (Monthly price * Gross margin) / Monthly churn. 2. LTV/CAC ratio. 3. CAC payback time (in months). 4. Monthly Recurring Revenue (MRR) and Annual Recurring Revenue (ARR). 5. Net customer lifetime value (Net LTV). Interpret the results: if ratio < 1, the model is not viable; between 1 and 3, acceptable; > 3, excellent. Suggest actions to improve the metrics (increase price, reduce churn, optimize CAC). Provide precise numbers and actionable recommendations.
