LTV CAC Ratio Calculator Formula & Method
This tool utilizes standard accounting algorithms to compute business returns:
Where Net Customer Value = LTV - CAC
Where:
- LTV: Gross profit lifetime value generated per customer.

- Ratio: Multiple of lifetime value relative to acquisition cost.
Worked Example
Example: $1,500 LTV vs $300 CAC
- Customer Lifetime Value (LTV): $1,500.00
- Customer Acquisition Cost (CAC): $300.00
Applying the formula yields:
LTV:CAC Ratio: $1,500 / $300 = 5.00x
Net Customer Profitability: $1,500 - $300 = $1,200.00 per customer
