What is First-call resolution?

Also called: fcr, first contact resolution

Definition

First-call resolution is the share of contacts fully resolved without the customer having to call again about the same issue. It is the single metric most closely tied to customer satisfaction, and the one most often measured in a way that flatters itself.

In practice

How first-call resolution actually works

The measurement problem is the repeat window. Resolution counted over 24 hours looks far better than the same data over seven days, and only one of those matches what the customer experienced.

Agent self-reporting inflates it further. The reliable definition is behavioural: no further contact from the same customer about the same issue within the window, however the agent felt the call went.

Improving it is usually a matter of authority rather than skill. Agents who cannot issue a credit, override a rule or commit a date will transfer or call back, however well they handle the conversation.

FCR is also the metric most improved by changes outside the contact centre. Clearer billing, a fixed product defect or a better self-service page removes repeat contacts entirely, which shows up as improved resolution without an agent doing anything differently — and is the only kind of improvement that also reduces volume.

Same calls, four numbers. Publish the window or the metric means nothing.
Measurement window	Typical FCR reported	Which is true?
Agent self-reported	85–95%	No — it measures optimism
24 hours	85–90%	Flattering
7 days	70–75%	The one that matches the customer's experience
30 days	65–70%	Strict, useful for trend

Worked example

Measured over 24 hours a team reports 89% FCR; measured over seven days, the same calls give 71%. The customers did not change their behaviour, only the window did.

First-call resolution: common questions

How is first-call resolution measured?

By whether the same customer contacts you again about the same issue within a defined window — commonly seven days. Counting an agent's opinion of the call instead consistently overstates it.

What is a good FCR rate?

Seventy to seventy-five per cent is respectable for most support operations over a seven-day window. Anything above ninety usually means the window is too short or the counting is agent-reported.

How do you improve FCR?

Give agents the authority to finish the call — refunds, overrides, commitments — and the information to answer without transferring. Training rarely fixes what a permissions model is causing.
