Mathematical Audit

How Referral Milestone Reward Value Is Calculated

The calculator determines the maximum reward budget at each milestone by comparing the cumulative subscriber value against reward and fulfillment costs.

Referred Subscribers Value = Milestone Referrals × Subscriber LTV
Max Reward Budget = Referred Subscribers Value × (Budget Allocation / 100)
Cost per Referred Subscriber = Reward Cost / Milestone Referrals
Program ROI = ((Total Referred Sub Value − Total Reward Costs) / Total Reward Costs) × 100
Active Referrers = Total Subscribers × (Referral Participation Rate / 100)

Referral-acquired subscribers cost approximately $0.17 each versus $1–$3 from paid channels. Only 1–5% of subscribers actively refer, but referred subscribers show higher open rates and retention. Start with 3–5 milestone tiers and expand based on performance data.

Real-World Scenario Example

"A newsletter with 10,000 subscribers, 3% referral rate, $5 subscriber LTV, milestone at 5 referrals with $10 reward cost."

totalSubscribers:10000
referralRate:3
subscriberLtv:5
milestoneReferrals:5
rewardCost:10
