Expansion MRR
Monthly recurring revenue added from existing customers through upsells, cross-sells, or seat additions.
FAQs
How is expansion MRR calculated?
Expansion MRR is calculated by summing all MRR increases from existing customers in a given month. If a customer upgrades from a $500/month plan to an $800/month plan, they contribute $300 of expansion MRR. If another customer adds 5 seats at $50 each, they contribute $250 of expansion MRR. Sum all such increases across your customer base for the month to get total expansion MRR. This figure excludes MRR from brand-new customers, which is counted as new MRR.
What drives high expansion MRR?
High expansion MRR is driven by product design (usage-based or seat-based pricing that scales naturally with customer growth), active customer success motions (identifying expansion opportunities and making targeted upsell pitches), account management processes (regular business reviews where additional needs surface), and a product roadmap that continuously adds value-added modules customers want to purchase. Expansion is easier to generate when pricing aligns with the value customers derive as their usage grows.
Can a company grow solely through expansion MRR?
Theoretically yes—if expansion MRR consistently exceeds churned and contracted MRR, a company achieves net revenue growth without new customer acquisition, known as negative net churn. In practice, even companies with strong expansion MRR continue investing in new customer acquisition to diversify concentration risk and grow the total addressable market. Some mature enterprise SaaS companies do generate most of their revenue growth from expansion within their existing base rather than new logos.
