• Low friction (just an email)
• Both parties benefit equally

Incentive Sizing Framework

Calculate your maximum incentive:

Max Referral Reward = (Customer LTV × Gross Margin) - Target CAC

Example:

• LTV: $1,200
• Gross margin: 70%
• Target CAC: $200
• Max reward: ($1,200 × 0.70) - $200 = $640

Typical referral rewards:

• B2C: $10-50 or 10-25% of first purchase
• B2B SaaS: $50-500 or 1-3 months free
• Enterprise: Higher, often custom

Viral Coefficient & Metrics

Key Metrics

Viral coefficient (K-factor):

K = Invitations × Conversion Rate

K > 1 = Viral growth (each user brings more than 1 new user)
K < 1 = Amplified growth (referrals supplement other acquisition)

Example:

• Average customer sends 3 invitations
• 15% of invitations convert
• K = 3 × 0.15 = 0.45

Referral rate:

Referral Rate = (Customers who refer) / (Total customers)

Benchmarks:

• Good: 10-25% of customers refer
• Great: 25-50%
• Exceptional: 50%+

Referrals per referrer:

Benchmarks:

• Average: 1-2 referrals per referrer
• Good: 2-5
• Exceptional: 5+

Calculating Referral Program ROI

Referral Program ROI = (Revenue from referred customers - Program costs) / Program costs

Program costs = Rewards paid + Tool costs + Management time

Track separately:

• Cost per referred customer (CAC via referral)
• LTV of referred customers (often higher than average)
• Payback period for referral rewards
