How Referral Rate Is Calculated

Referral Rate % = Referred Customers ÷ Total New Customers × 100

Referral rate measures the share of new customers who arrived because an existing customer sent them. Divide customers attributed to referrals by all new customers in the period. Worked example: 45 of 620 new customers coming from referral links is 45 ÷ 620 = 7.3%. Top-quartile programs hit 16%+, usually with two-sided rewards. Multiply by referral revenue to prioritize: 45 customers × $85 average = $3,825 of nearly free acquisition — no ad spend, high trust, and referred customers typically retain 16-25% longer.
