What is First Response Time (FRT)?

First Response Time (FRT) is the average time between a customer reaching out and getting the first human (or AI) reply. It's a first impression metric: a fast first response reassures customers their issue is being handled, even if the full resolution takes longer. It strongly influences satisfaction.

Why FRT matters

Customers tolerate a longer resolution far better when the first response is quick — silence is what frustrates them. A fast FRT signals "we've got this," sets expectations, and buys your team room to resolve thoroughly. It's often the single most visible support metric to customers.

How to improve FRT

Set up auto-acknowledgements, route conversations quickly, and use saved replies for common openers. The biggest win is letting an AI agent answer instantly around the clock — for documented questions the first response can be the full resolution, and for the rest the customer still gets an immediate, useful reply while a human picks it up.

Formula

FRT = Total time to first reply across conversations ÷ Number of conversations

Example: If 50 tickets took a combined 500 minutes to first reply, FRT = 500 ÷ 50 = 10 minutes.

Questions about First Response Time (FRT)

What is a good first response time?

It depends on channel: live chat expects seconds to a couple of minutes, email a few hours, with under 1 hour considered strong. Set targets per channel and track against your SLA.

Does an auto-reply count as a first response?

Usually not — most teams measure FRT to the first substantive reply, not an automated "we got your message" acknowledgement. An AI agent's genuine answer, however, does count.

Average Speed of Answer (ASA)

Average Speed of Answer (ASA) is the average time a customer waits in the queue before their contact is answered by an agent. Most common in chat and phone support, it measures queue wait specifically (not how long the whole interaction takes), and it's a direct driver of abandonment and satisfaction.

Average Handle Time (AHT)

Average Handle Time (AHT) is the average total time it takes to handle a single customer contact — including talk or chat time, any hold time, and the after-contact work like notes and follow-ups. It's a core efficiency metric, but it should never be optimized at the expense of resolution quality.

First Contact Resolution (FCR)

First Contact Resolution (FCR) is the percentage of customer issues fully resolved in a single interaction — no follow-ups, no callbacks, no reopened tickets. It's one of the strongest support metrics because high FCR correlates with both lower costs and higher satisfaction: customers get their answer once and move on.
