Understanding LTV / CAC Ratio

What is LTV / CAC Ratio?

The LTV / CAC ratio measures the relationship between how much you spend to acquire a customer and how much that customer is worth over their lifetime. It's one of the most important metrics for assessing the health and sustainability of your business model. A healthy ratio indicates that your customer acquisition strategy is efficient and sustainable.

How to Calculate LTV / CAC Ratio

LTV / CAC Ratio = Customer Lifetime Value / Customer Acquisition Cost

Example Calculation

If your average customer is worth $600 (LTV) and it costs $150 to acquire them (CAC):

  • LTV: $600
  • CAC: $150
  • Ratio: $600 / $150 = 4.0x

This means for every $1 spent on acquisition, you earn $4 in customer lifetime value. This is a healthy ratio.

What is a Good LTV / CAC Ratio?

A good LTV / CAC ratio varies by industry and business model:

  • Below 1.0: Unhealthy - losing money on each customer
  • 1.0 - 3.0: Low - needs improvement
  • 3.0 - 5.0: Healthy - good balance
  • Above 5.0: Excellent - very healthy, consider scaling up

Why is LTV / CAC Ratio Important?

The LTV / CAC ratio is crucial for several reasons:

  • Business Health: Indicates whether your business model is sustainable
  • Investment Decisions: Helps determine if you can afford to scale acquisition
  • Pricing Strategy: Informs pricing decisions to improve profitability
  • Marketing Efficiency: Measures how effectively marketing dollars are being spent
  • Investor Confidence: Key metric for investors evaluating business viability
