About This Template
Unit economics are the fundamental financial drivers of a business — they show whether the core model makes money at the level of a single customer or transaction. Strong unit economics mean the business becomes more profitable as it scales. Weak unit economics mean scaling makes losses worse. This template guides founders and finance teams through entering their core metrics, then uses AI to calculate complete unit economics, interpret what the numbers mean for the business model, and identify the highest-leverage improvements.

You are a venture capital analyst evaluating the unit economics of a SaaS business. Using the data below, produce a comprehensive unit economics analysis. Company: [company_name] Average monthly revenue per customer: [average_revenue_per_customer] Gross margin: [gross_margin] percent Monthly churn: [monthly_churn] percent CAC: [cac] CAC by channel: [cac_breakdown] Sales cycle: [sales_cycle] Monthly expansion revenue per customer: [expansion_revenue] Calculate and produce: 1. LTV Calculation — using LTV = (ARPU x Gross Margin) divided by Monthly Churn Rate 2. CAC Analysis — blended CAC and by channel if provided 3. LTV/CAC Ratio — and interpretation (less than 1 is broken, 1-3 is marginal, 3+ is healthy, 5+ is strong) 4. CAC Payback Period — months to recover CAC from gross profit 5. Gross Profit Per Customer — monthly and annual 6. Contribution Margin — including CAC amortization 7. Unit Economics Assessment — is this business model fundamentally sound at scale? 8. Improvement Recommendations — the highest-leverage actions to improve LTV/CAC Show all formulas and calculations.
Sample Output
This is an example of what AI produces when you use this template.
Unit Economics Summary
LTV: ($850 ARPU multiplied by 75% gross margin) divided by 2% monthly churn equals $31,875. CAC: $1,400 blended. LTV/CAC ratio: $31,875 divided by $1,400 equals 22.8x. CAC Payback Period: $1,400 divided by ($850 multiplied by 75%) equals 2.2 months. Gross profit per customer per month: $637.50. Annual gross profit per customer: $7,650.
Unit Economics Assessment
These unit economics are exceptional. An LTV/CAC of 22.8x is well above the 3x threshold considered healthy for SaaS. A 2.2-month CAC payback period is among the fastest in the industry — it means the business recovers its customer acquisition investment in just 2 months and then generates gross profit for years. The 2 percent monthly churn (22.5 percent annually) is the primary risk factor — if churn can be reduced to 1.5 percent, LTV increases by 33 percent to $42,500 and LTV/CAC improves to 30.4x. The highest-leverage improvement is churn reduction: every 0.1 percentage point reduction in monthly churn adds approximately $3,187 to LTV at current ARPU and margin.
