Customer Lifetime Value (LTV)

What it actually means

LTV answers a simple question: if this customer stays for the average lifetime of a customer at your company, how much revenue do they bring in total? For subscription or recurring revenue businesses, that's straightforward. For services and complex enterprise deals, it still applies, you're just estimating renewal, expansion, and referral revenue instead of a clean monthly charge (source: SalesHive).

The basic mechanics, per Cube Software: average revenue per user (ARPU) is monthly recurring revenue divided by number of users. Customer lifetime is the average number of months or years a customer sticks around before churning. Multiply the two and you get LTV.

Why it matters when you're selling on LinkedIn

Most founders and reps judge whether their LinkedIn content is 'working' by looking at cost-per-lead or comparing it to paid acquisition channels. That's the wrong yardstick. A post takes an hour of your time and produces three inbound conversations. Compared against a CAC benchmark built for paid ads, that looks inefficient. Compared against what those three customers will actually pay you over three years, it looks like the best channel you have.

The misconception

The mistake is treating content like a paid channel and demanding the same immediate, per-lead accounting. Paid channels are judged on CAC because the cost is explicit and the volume is programmatic. Content doesn't work that way. The leads are fewer, warmer, and often larger. If you only look at cost-per-lead, a founder spending time on LinkedIn instead of outbound looks like a bad trade. If you look at LTV, the math usually flips, because the deals that come from content tend to be higher-trust, higher-retention relationships, not one-off transactions.

How to actually use it

Don't evaluate a LinkedIn post by what it cost you to write. Evaluate the channel by tracking, over a quarter or two, what the customers sourced from it are worth once you multiply their ARPU by their observed or expected lifetime. If those customers retain longer or expand more than customers from other channels, that's the number that justifies the time, not the cost-per-lead spreadsheet.
