Latest / The CMO Podcast with Fexingo: Marketing Leadership, Budgets, and Executive Strategy / Why Every CMO Needs a 75 Percent Retention Rule
Transcript
- Lucas: So there's this number that's been floating around CMO circles — 75 percent. It's not a conversion rate or a gross margin. It's the retention rate of customers acquired through a given campaign, and the argument is that if you're not hitting 75 percent retention, you're probably wasting money. Luna: Right, I've seen this called the 'Retention 75' rule. It got a lot of traction after a Bain study in 2023 and then a leaked internal memo from Spotify's CMO. Lucas: Exactly. The Bain study looked at hundreds of brands and found that companies that hold customers at a 75 percent or higher retention rate over 12 months grew revenue at roughly two and a half times the rate of companies below that threshold. And their marketing spend as a percentage of revenue was actually lower. Luna: So the 75 percent isn't just a vanity metric. It's a leading indicator of whether your acquisition spend is actually creating long-term value. Lucas: Precisely. And the Spotify memo — which was shared on Blind and then picked up by a few outlets — basically told the marketing team: any campaign that doesn't project a 12-month retention rate above 75 percent gets its budget cut or redirected. That's an aggressive stance. Luna: Aggressive but logical. If you're a subscription business, your unit economics live or die on retention. But does this rule apply to non-subscription models? Like a DTC brand selling a $40 candle? Lucas: Great question. Let's look at Peloton. After the pandemic boom, Peloton's retention cratered. In 2021, they had roughly 80 percent retention on their connected fitness subscriptions. By 2023, that number had dropped to around 60 percent. Their marketing spend was still high — they were trying to acquire new users — but the churn was eating all the gains. Luna: So they were essentially paying to acquire customers who would leave in a few months. That's a classic leaky bucket. Lucas: Exactly. In 2024, Peloton's new CMO, Leslie Berland, came in and explicitly adopted a retention-first framework. She cut new customer acquisition spend by 30 percent and redirected that budget into loyalty programs, content, and community events. Within two quarters, retention moved from 60 percent back to 72 percent. Luna: 72 — still not quite 75, but a huge improvement. And presumably the LTV of those retained customers more than compensated for the lower acquisition volume. Lucas: Right. Peloton's average subscriber lifetime value jumped from about $1,200 to $1,800. And the stock — well, it's still volatile, but the operating losses narrowed significantly. Luna: Let's talk about Zoom. They had a different problem. During the pandemic, they had massive organic growth. By 2024, they were trying to retain enterprise customers who were evaluating alternatives. Their marketing team used the 75 percent rule to justify cutting acquisition spend and focusing on customer success. Lucas: Yeah, Zoom's enterprise marketing head — I think her name is Janine Pelosi — presented a case at a conference last year. She showed that campaigns targeting existing customers for upsells had a 12-month retention rate of 82 percent, while campaigns targeting net new accounts had only 68 percent retention. So they shifted 40 percent of their acquisition budget into upsell and retention programs. Luna: That's a huge reallocation. And it worked, right? Zoom's net dollar retention went from 95 percent to 112 percent over 2025. Lucas: It did. And that's the power of having a simple benchmark. It gives you a rule of thumb to challenge budget proposals. 'Show me your projected 12-month retention, and if it's below 75, we're not funding it.' Luna: But what about a DTC brand that sells a one-time purchase? Like, say, a mattress company. Retention doesn't really apply the same way. Lucas: That's the limitation. For non-recurring revenue businesses, the metric needs to be adjusted. Some CMOs use a 'repeat purchase rate' threshold — 75 percent of customers purchasing again within 18 months. But the principle is the same: if your acquisition isn't leading to a second purchase, the unit economics break. Luna: So it's about the behavior, not the subscription. I think that's a fair translation. There's a company called Casper — they struggled with exactly this. They had high initial acquisition but low repeat rates. Their LTV couldn't support the CAC. Lucas: Exactly. And once they went private in 2021, they actually pulled back on performance marketing and focused on retail partnerships and product extensions. I don't know their current retention numbers, but the pivot suggests they recognized the same problem. Luna: So the 75 percent rule is really a diagnostic. It tells you whether your acquisition machine is creating value or just burning cash. And it's simple enough that a CEO can understand it. Lucas: That's the beauty of it. You don't need a complex attribution model. You just need to track cohorts. If the cohort of customers you acquired in January 2025 is still active in January 2026 at a 75 percent rate, your marketing is working. If not, you've got a problem. Luna: And this is especially relevant now, in mid-2026, because marketing budgets are under pressure. Interest rates are still relatively high, and CFOs are demanding ROI. The 75 percent rule gives CMOs a defensible framework. Lucas: Absolutely. I've talked to a few CMOs off the record, and they say the rule is gaining traction in boardrooms. One told me that when she presents her budget, she now leads with retention rates by campaign. It's changed the conversation from 'how much are we spending' to 'how much are we keeping'. Luna: That's a powerful reframe. So what's the one thing a listener should take away from this episode? Lucas: If you're a marketing leader, calculate your 12-month retention rate by acquisition channel. If any channel is below 75 percent, ask yourself: is this channel creating long-term value, or is it just volume? And be honest about the answer. Luna: And if you're a CMO presenting to your board next week, maybe lead with that Peloton example. It's a concrete story of a brand that saved itself by focusing on retention. Lucas: Exactly. The 75 percent rule isn't a magic number — it's a starting point for a healthier marketing operation.
