Questions fréquentes

What is a good LTV to CAC ratio?

A ratio of 3:1 or higher is typically considered healthy, meaning the customer value is three times the acquisition cost. Ratios below 1 indicate you're losing money on each customer.

How is LTV calculated?

LTV is usually calculated as average purchase value × purchase frequency × customer lifespan. This calculator takes LTV as an input, so you need to compute it separately.

What if my CAC is zero?

The calculator uses a minimum CAC of 0.01 to avoid division by zero, but a zero CAC is unrealistic. Ensure you enter a positive CAC.

LTV to CAC Ratio

LTV / CAC

This ratio compares the total revenue a customer generates over their lifetime to the cost of acquiring them. A higher ratio indicates more efficient acquisition.

Example:

Input: LTV = $500, CAC = $100

Calculation: 500 / 100

Result: 5.0x

Cas d'utilisation réels

Où ce calcul apparaît dans la vie quotidienne.

Evaluate Marketing ROI

Determine if your marketing spend is justified by the long-term value of acquired customers.

Example: If LTV is $600 and CAC is $150, ratio is 4x, indicating good ROI.

Set Acquisition Budgets

Use the ratio to decide how much you can afford to spend on acquiring a customer while staying profitable.

Example: If target ratio is 3 and LTV is $900, max CAC is $300.

Compare Customer Segments

Calculate the ratio for different customer groups to identify which segments are most profitable.

Example: Compare high-value vs. low-value customers to allocate resources.

Conseils et erreurs courantes

Tips

  • Aim for a ratio of at least 3:1 to ensure healthy margins.

  • Include all acquisition costs (ad spend, sales team, tools) in CAC.
  • Use cohort analysis to get accurate LTV.

Common Mistakes to Avoid

  • Forgetting to include all acquisition costs in CAC.
  • Using a short customer lifespan, underestimating LTV.
  • Ignoring the time value of money when calculating LTV.

Hypothèses et limites

  • Use the stated inputs and units.
  • Results are estimates for planning and education.
  • Check measurements and source data before making an important decision.
