About this tool
Unit economics evaluate the direct revenues and costs associated with an individual customer account. In subscription software, a company can easily raise millions in funding or post rapid top-line growth while maintaining fundamentally broken underlying unit economics. If the cost to acquire and service a customer exceeds the net gross profit that customer ever returns, the business loses money on every sale—and scaling sales merely accelerates the company's demise. A healthy unit economics profile brings together four core pillars: strong ARPU, high gross margins (>80%), an LTV:CAC ratio exceeding 3:1, and a CAC payback period under 12 months. Use this dashboard to view all your core unit economics in one unified summary.
How It Works
- 1Input your monthly ARPU and Gross Margin percentage.
- 2Input your monthly customer churn rate percentage.
- 3Input your fully loaded Customer Acquisition Cost (CAC).
- 4Inspect your complete unit economics summary: margin-adjusted LTV, LTV:CAC ratio, CAC Payback period in months, and health status.
Formula & Math
Transparent LogicLTV = (ARPU × Margin%) / Churn%; Payback = CAC / (ARPU × Margin%); Ratio = LTV / CAC
Worked Practical Example
ARPU = $60/mo, Gross Margin = 80%, Monthly Churn = 3%, CAC = $360.
Calculation / Steps
LTV = ($60 × 0.80) / 0.03 = $1,600. LTV:CAC = $1,600 / $360 = 4.44. Payback = $360 / $48 = 7.5 months.
Expected Result
Outstanding unit economics: 4.44x LTV:CAC and 7.5 months payback horizon.
Frequently Asked Questions
What is the single most sensitive variable in SaaS unit economics?+
Customer churn rate. Because churn is in the denominator of LTV, a 1% reduction in churn has a disproportionately positive impact on overall unit economics.
Can a low-ARPU business have great unit economics?+
Yes, provided customer acquisition is low-touch and automated (low CAC) and customer retention is strong.
How does BoolBul optimize unit economics?+
BoolBul directly targets the churn variable, expanding LTV and accelerating payback without requiring changes to marketing spend.
Automate retention on your cancel button
BoolBul strengthens your entire unit economics dashboard by expanding lifetime value at the critical moment of cancellation.
