What is expansion MRR and contraction MRR?
Short Answer
Expansion MRR is new revenue from existing customers (upsells, cross-sells, seat expansion). Contraction MRR is lost revenue from downgrades, seat reductions, or feature cancellations.
Full Explanation
Net Revenue Retention (NRR) is calculated as (beginning MRR + expansion MRR − contraction MRR − churn MRR) / beginning MRR. High-performing SaaS companies achieve NRR above 120%, meaning that revenue from existing customers grows faster than churn. Expansion MRR typically comes from three sources: seat expansion (more users), feature upgrades (moving from Standard to Premium tier), and upsells of new products. Contraction MRR reveals where you're losing revenue — whether from price-sensitive customers downgrades, feature removal (unusual), or competitive displacement. Companies with strong expansion MRR often have excellent retention because power users discover new value and expand usage. Conversely, companies with high contraction MRR typically signal product stagnation or poor customer success. Opagio's calculator allows you to model expansion and contraction scenarios to forecast long-term MRR growth.
Understanding the relationship between operational metrics and intangible asset value is critical for startup founders. Metrics like customer lifetime value, net revenue retention, and feature adoption rate are not just operational indicators — they are direct inputs into intangible asset valuations. A SaaS company with 130% net revenue retention has fundamentally more valuable customer relationships than one with 90% retention, and this difference compounds over time into a significant enterprise value gap. Tracking these metrics consistently enables founders to demonstrate value creation to investors with quantitative evidence.
