Step one: what is an engaged member worth? For loyalty and cashback programs, the numbers generally land in this range [ESTIMATE — varies widely by program]: annual transaction-driven value in the low hundreds per active member, higher for premium tiers, multiplied over a multi-year member lifetime. For the worked example below, we'll use a conservative $300 annual value per engaged member [ESTIMATE]. Adjust with your own numbers — the method matters more than our inputs.

Step two: how many calls go unanswered? This is the number most programs don't know, because unanswered calls are invisible. Industry analyses suggest [ESTIMATES — your mileage will vary]: during business hours, a meaningful share of calls go unanswered at busy operations — lines engaged, agents with members, lunch breaks. After hours, the overwhelming majority — often effectively all of them. Roughly 20–40% of call attempts to consumer businesses happen outside business hours.

Step three: the worked example. Take a hypothetical mid-size program [ESTIMATE — illustrative only]: 200 member calls per month; 15% go unanswered (30 calls); of those, 25% belong to members who disengage within the year (8 members); your program recovers none of them (voicemail, no callback). 8 × $300 annual value = $2,400/month in member value at risk. That's $28,800 a year [ESTIMATE] — from 30 missed calls a month. Even if our inputs are off by half, the number still justifies fixing the phones. And this ignores the referrals a happy member brings.

The compounding effect over a year understates the damage, because member value compounds. An engaged member doesn't just bring annual value — they bring referrals. Loyalty programs live on network effects; industry rules of thumb suggest an enthusiastic member refers 1–2 others over their lifetime [ESTIMATE]. So each lost member plausibly costs you their value plus a fraction of another's. The table version: 10 missed member calls/month → ~3 disengaged → ~$10,800/year at risk [ESTIMATE]; 30 → 8 → ~$28,800/year [ESTIMATE]; 60 → 15 → ~$54,000/year [ESTIMATE].

Not all missed calls are equal. A member calling about a routine promotion is an inconvenience; a new member calling with a redemption problem in their first month is churn walking out the door — early-life issues disproportionately decide whether someone stays. When you do call tracking, segment new vs. tenured members. If anything, our math above is conservative.

How to measure your own numbers in two weeks: enable call tracking (a tracking number on your website and app support page — many are free to start); tag new vs. tenured members; count the after-hours share; apply your actual average member annual value. Two weeks of data beats a year of guessing. The hidden costs nobody adds up: reviews ("support never answers" is a common 1-star theme), agent burnout from voicemail phone tag, and ad waste — if you spend on acquisition driving signups nobody supports, you're paying for churn.
