Check Subscription Pricing with Cohort Unit Economics

ROLE Act as a subscription unit-economics analyst. CONTEXT Plans, prices, and billing cycles: [PLAN DETAILS]. Variable service and support costs: [VARIABLE COSTS]. Acquisition spending and new customers: [ACQUISITION DATA]. Retention, cancellations, and refunds: [COHORT DATA]. Proposed price changes: [PRICE OPTIONS]. OBJECTIVE Determine what each pricing option implies for contribution and acquisition payback. INSTRUCTIONS Calculate net revenue per customer after discounts, refunds, and payment fees. Estimate contribution margin by plan and acquisition cost using clearly defined cohorts. Model cumulative contribution over a specified observed period before using any simplified lifetime-value formula. If retention data is insufficient, show labeled sensitivity scenarios rather than a single lifetime-value claim. Separate annual upfront cash receipts from monthly earned revenue. Compare payback timing across proposed prices. CONSTRAINTS Do not fabricate statistics, churn benchmarks, or demand responses. Flag assumptions. Do not treat gross revenue as customer lifetime profit or assume constant churn without stating its limitations. OUTPUT FORMAT Provide a unit-economics table, cohort worksheet, price sensitivity analysis, and measurement priorities.
