Calculation Methodology

Unit economics is the fundamental building block of business profitability. We use the following formulas to analyze your performance:

1. Customer Acquisition Cost (CAC)

Calculated by dividing the total marketing and sales spend by the number of new customers acquired during the same period.

$$CAC = \frac{\text{Total Marketing Spend}}{\text{New Customers Acquired}}$$

2. Customer Lifetime Value (LTV)

The total net profit a customer generates over their entire relationship with your company. We include Gross Margin for a more accurate financial picture.

$$LTV = ARPU \times \text{Customer Lifetime} \times \text{Gross Margin}$$

Where Customer Lifetime is calculated as $$1 / \text{Churn Rate}$$.

3. Payback Period

The number of months required for a customer to generate enough gross profit to cover their acquisition cost.

$$Payback Period = \frac{CAC}{ARPU \times \text{Gross Margin}}$$

A 3:1 LTV/CAC ratio is widely considered the benchmark for a healthy, scalable business model.
