If you’re managing capital one of the first things you realize is that it’s more expensive to acquire new customers than it is to sell to existing customers. If you wanted to get technical you can look at customer life time values and costs of acquisition.
The below data comes from Sammy Abdullah at Blossom Ventures, who curates some awesome analysis. His data shows how public SaaS companies leverage customer acquisition costs to sell more to existing customers under a metric called net retention. Formulaically net retention is calculated as beginning of period revenue + upgrades — downgrades — churn all divided by beginning of period revenue. If that formula yields a number greater than 100%, then growth from your existing customer base more than offset any losses from that customer base.
