Contraction MRR is the monthly recurring revenue lost when existing customers downgrade their plan, reduce seats, or move to a lower tier — without cancelling entirely. It is a leading indicator of churn: accounts that downgrade often cancel in the following quarter.
High contraction is an early warning sign that customers are trimming budgets, hitting usage limits they do not need, or finding value in only part of the product. Customer success teams use contraction signals to trigger proactive outreach before an account goes dark entirely.
