A short YouTube talk by Peter Vander Wall explaining two core KPIs for scaling a business: Customer Acquisition Cost (CAC) and lifetime Gross Profit. The speaker frames the pair as measuring the cost to acquire a customer versus the gross profit earned over that customer's lifetime, thus indicating ROI on growth spend. Includes a numeric example: spending $5,000/month to acquire five clients (CAC = $1,000) and estimating $25,200 lifetime gross profit per client to show the investment-arbitrage view of business growth.

There's two main KPIs are really important to be tracking as you scale your business. Now, the reason both of these KPIs are really important here, CAC and lifetime Gross profit, is because this is the difference of what it costs to get a customer versus how much you make from a customer. Okay. So this is really your ROI on money spent into growing the business. Let's say I'm spending 5,000amonth and I'm getting five new clients. So my CAC is $1,000. And let's take this bookkeeping firm example here, and I'm going to make $25,200 over the lifetime of this client. Then that's a arbitrage. There's not many other things you could spend a thousand dollars into and get 25 grand back, right? Maybe some sort of crypto thing if you're into that. But this is where we start to look at our business as an investment vehicle, not as a day job.
