How to understand and use this calculator

What is Customer Referral Value (CRV)?

Customer Lifetime Value (LTV) measures the direct revenue a customer spends with your brand. But active promoters bring additional value by referring other customers. Customer Referral Value (CRV) is the monetary value an advocate customer contributes through their referral behaviors.

By measuring CRV, marketing teams can justify higher reward incentives and calculate the true value of their advocate segment. Compare referral loyalty metrics with the Net Promoter Score (NPS) calculator or calculate direct customer value using the customer lifetime value calculator.

The CRV and advocate math formulas

Referral program value is modeled using active audience, sharing rates, and referred value:

$$\text{Active Advocates} = \text{Total Active Customers} \times \left(\frac{\text{Share Rate (\%)}}{100}\right)$$

$$\text{Successful Referrals} = \text{Active Advocates} \times \left(\frac{\text{Referral Conversion Rate (\%)}}{100}\right)$$

$$\text{Total Referred Revenue} = \text{Successful Referrals} \times \text{Referred LTV}$$

$$\text{Total Rewards Cost} = \text{Successful Referrals} \times \text{Referral Reward Cost}$$

$$\text{Net Referral Value} = \text{Total Referred Revenue} - \text{Total Rewards Cost}$$

$$\text{CRV per Advocate} = \frac{\text{Net Referral Value}}{\text{Active Advocates}}$$

$$\text{Net Referral ROI (\%)} = \frac{\text{Net Referral Value}}{\text{Total Rewards Cost}} \times 100$$

Where Share/Invite Rate is the percentage of your customer base that actively shares their referral link, and Referral Conversion Rate is the percentage of invited users who complete a signup or purchase.

Viral growth loops and organic acquisition

Referrals create organic growth loops that lower your blended customer acquisition costs. A strong referral engine increases your customer K-Factor. Monitor your viral growth potential using the viral coefficient (K-Factor) calculator to analyze scale velocity.
