Unit Economics Calculator
Calculate your unit economics to understand customer profitability, scalability potential, and business health. This calculator analyzes per-customer metrics essential for sustainable growth.
What is Unit Economics?
Unit economics measures the revenue and costs associated with a single unit of your business, typically a customer or product.
Why Unit Economics Matters
Unit economics reveals whether your business model is profitable at the individual customer level and helps determine how much you can afford to spend on customer acquisition.
Key Unit Economics Metrics
LTV/CAC ratio, payback period, and customer profitability are essential metrics for evaluating business sustainability.
LTV/CAC Analysis
LTV/CAC ratio shows the return on customer acquisition investment. A ratio above 3:1 generally indicates a healthy business model.
Scalability Analysis
Breakeven analysis and operating leverage help determine how your profits scale with customer growth.
Understanding Unit Economics in Detail
Unit economics focuses on the profitability of individual customer relationships, providing a granular view of business sustainability. By analyzing revenue and costs per customer, businesses can determine whether their growth model is viable and scalable.
The Unit Economics Framework:
• Average Revenue Per User (ARPU)
• Monthly Recurring Revenue (MRR)
• Customer Lifetime Value (LTV)
• Revenue per customer segment
• Expansion revenue potential
• Customer Acquisition Cost (CAC)
• Customer Service costs
• Product delivery costs
• Churn prevention costs
• Operational overhead allocation
• Gross margin per customer
• Contribution margin
• Customer profitability
• Payback period
• Return on customer investment
• Viral coefficient
• Referral economics
• Network effects
• Customer lifetime expansion
• Market penetration potential
The key insight from unit economics is understanding whether each customer relationship contributes positively to overall profitability. This customer-level analysis reveals whether your business model can scale profitably.

Limitations of Unit Economics Analysis
Data Accuracy Challenges
- • Attribution of acquisition costs across channels
- • Accurate customer lifetime value estimation
- • Proper cost allocation to customer segments
- • Accounting for customer expansion and contraction
- • Seasonal variations in customer behavior
Business Model Limitations
- • Network effects and platform businesses
- • Freemium models with conversion dynamics
- • B2B enterprise sales with long sales cycles
- • Multi-sided marketplace economics
- • Viral growth and organic acquisition
When Unit Economics Require Special Consideration
• Early Stage: Limited historical data makes projections uncertain
• Multi-Product: Complex when customers use multiple offerings
• Enterprise Sales: Long sales cycles and high-touch models
• Platform Businesses: Network effects create non-linear economics
• Seasonal Businesses: Customer behavior varies significantly by period
Frequently Asked Questions
What's considered a good LTV/CAC ratio?
Generally, a LTV/CAC ratio of 3:1 or higher is considered excellent, indicating strong unit economics. Ratios between 2:1 and 3:1 are good, while anything below 2:1 requires careful examination of the business model and may indicate unsustainable customer acquisition costs.
How do I calculate customer lifetime value accurately?
Customer lifetime value is calculated as Average Revenue Per User × Customer Lifespan. Use historical cohort analysis to determine actual customer lifespan, and consider factors like expansion revenue, churn rates, and discount rates for long-term customers.
What should my payback period be?
Payback periods vary by industry and business model. SaaS companies typically aim for 6-18 months, while e-commerce businesses often achieve 1-3 months. The key is balancing customer acquisition investment with cash flow requirements.
