Contraction MRR (or ARR) is the recurring revenue lost due to existing customers reducing their spend — like downgrading plans, removing seats, or decreasing usage. While churn gets more attention, contraction is an early warning sign of product disengagement or shifting customer priorities. For sales, CS, and RevOps teams, tracking contraction helps diagnose account health and prevent larger revenue losses before they happen.
What is Contraction MRR/ARR?
Contraction MRR/ARR measures the reduction in recurring revenue from customers who remain active but are spending less than they used to. It doesn’t include full cancellations (that’s churn), but rather downsizing events that lower the monthly or annual contract value.
Formula:
Contraction MRR = Total decrease in MRR from active accounts
Contraction ARR = Total decrease in ARR from active accounts
Common contraction scenarios:
- Plan downgrade (e.g., from Pro to Basic)
- Seat/license reduction
- Removal of add-ons or product modules
- Lower usage billing (for volume-based pricing)
Why It Matters in B2B SaaS
- It signals revenue risk before churn. Contraction often precedes customer churn, making it an important early flag.
- It affects net growth rates. Contraction directly impacts Net Revenue Retention (NRR), even if the customer stays.
- It helps identify product gaps or value perception issues. If key features are being dropped or downgraded, it could signal a mismatch between product offering and customer needs.
- It’s often overlooked — but crucial. Companies overly focused on new sales can miss that revenue is quietly slipping through retained accounts.
- It influences expansion strategy. Knowing where contraction is happening helps GTM teams rebalance expansion motions and pricing strategies.
How to Measure Contraction MRR/ARR
- Identify active customers who reduced their recurring spend during the measurement period
- Calculate the difference between old and new contract values
- Only include changes that affect recurring revenue
- Exclude:
- Full cancellations (Churned MRR)
- One-time charge removals
- Discounts or incentives unless they permanently reduce the contract value
Best Practices
- Track contraction alongside churn and expansion to get a full picture of account movement
- Use product usage data to investigate if contraction followed a drop in engagement
- Interview at-risk customers to understand why they reduced — pricing, value, product limitations?
- Flag downgrades in your CRM to prompt follow-up conversations
- Look for contraction trends by customer segment or plan tier
