What is support deflection?
Support deflection rate is the share of customer issues resolved through self-service, like a help center or chatbot, without ever reaching a live agent. It is a measure of how much your knowledge base and product guidance carry on their own.
Higher deflection lowers cost, but only if customers actually get an answer. A high rate that hides unresolved problems just relocates the cost to churn.
The deflection formula.
Support deflection rate = (deflected issues divided by total inquiries) times 100. Decide what counts as deflected, usually a self-service session that did not escalate to a ticket, and hold the definition steady.
A worked example.
Of 1,000 inquiries this month, 700 are resolved by self-service. The deflection rate is 700 divided by 1,000, times 100, which is 70%.
What is a good deflection rate?
There is no universal target. A higher rate lowers support cost; a lower rate is fine if the issues that reach agents are the ones that really need them. Read deflection next to CSAT on those same self-service sessions, so you do not trade savings for frustration.
How to lift deflection without hurting CSAT.
Build help content around the top ticket drivers, surface answers in the product at the moment of confusion, and write so the answer actually resolves the question. Effort matters too: read it next to customer effort score.
