First Response Time
First response time (FRT) is the average time it takes for a customer support agent or system to send the first reply after a customer opens a ticket, starts a chat, or submits a contact form. It measures the speed of acknowledgment, not the speed of resolution. A short first response time tells customers their issue has been seen, even if the full answer takes longer.
Formula: Sum of all time-to-first-reply values / Total number of tickets
How is first response time calculated?
The metric is typically measured from the moment a ticket enters the queue to the timestamp of the first outbound message from support. Most helpdesk platforms calculate it automatically.
| Component | Definition |
|---|---|
| Start | Customer submits ticket, opens chat, or sends message |
| End | First reply from support agent or automated system |
| Measurement | Elapsed time (usually in hours or minutes) |
| Metric | Average across all tickets in a period |
For example, if three tickets take 10 minutes, 30 minutes, and 20 minutes to receive the first reply, the first response time is (10 + 30 + 20) / 3 = 20 minutes.
Why does first response time matter?
First response time is one of the strongest predictors of customer satisfaction. Research consistently shows that a fast first reply, even if it is only an acknowledgment, reduces customer anxiety and sets a positive tone for the rest of the interaction. For teams, it is a simple proxy for queue health: a climbing first response time usually means understaffing, rising volume, or routing problems.
Improving this metric is part of good customer support metrics discipline.

Frequently asked questions
What is a good first response time?
It depends on the channel. Email support typically targets under 12 to 24 hours, live chat aims for under 1 minute, and social media usually targets under 1 hour. The fastest teams use AI-powered responses to hit sub-second first replies on chat and contact forms.
How is first response time different from resolution time?
First response time measures only the speed to the first reply. Resolution time measures the full time from ticket open to final resolution. A team can have fast first response but slow overall resolution if the problem requires multiple back-and-forth exchanges.
How do you improve first response time?
The fastest path is automating the first reply with AI chat or contact form acknowledgments that include relevant help articles. Inside human-staffed queues, prioritize by urgency, staff peak hours properly, and use templates for common opening responses.
