What is Expansion Revenue?
Nexa Consultancy | Startup & Finance Glossary
Expansion Revenue is the additional Monthly Recurring Revenue (MRR) generated from existing customers. It is the lifeblood of a healthy SaaS business and is generated through three main levers: upselling (moving a customer to a higher-priced plan), cross-selling (selling them additional products or features), and add-ons (selling them more of the same, like additional seats or usage).
For Startups: Focusing on expansion revenue is often more cost-effective than acquiring new customers. It indicates a sticky product that customers are willing to embed deeper into their workflows. High expansion revenue is a key driver of Net Dollar Retention (NDR) and is a very positive signal to investors.
Example: A company using a project management tool on a basic plan decides to upgrade to the premium plan to get more features. This increase in MRR from an existing customer is expansion revenue.
