TL;DR
FRT is how long a customer waits for the first real human reply after reaching out.
Key Points
✓
FRT is the gap between an inbound [[chat-message]] from a [[website-visitor]] and the first reply from a [[support-operator]] — automated greetings like a [[welcome-message]] do not count [1][2].
✓
The standard formula is the sum of first-response times divided by the number of conversations; using the median instead of the mean avoids a few slow outliers skewing the number [3].
✓
Most teams measure FRT against [[business-hours]] only, so overnight and weekend gaps are not counted against agents who were off the clock [1][3].
✓
Expectations are channel-specific: live chat is judged in seconds (best-in-class around 45 seconds or less), while email is judged in hours [2][3].
✓
FRT is a speed metric, not a quality one — pair it with [[resolution-time]], [[first-contact-resolution]] and [[customer-satisfaction-score]] so fast replies do not come at the cost of helpful ones [1][4].
✓
A formal [[service-level-agreement]] often sets a target FRT (e.g. reply within 2 minutes on chat) and is the accountability layer many [[help-desk]] tools track against [1].

Average Response Time
Average Response Time (ART) is a support metric measuring the mean time customers wait for an agent reply across all messages in a period, not just the first one. It is calculated as total wait time divided by the number of replies sent.
Resolution Time
Resolution time is the elapsed time from when a customer first raises an issue until that issue is fully resolved and the conversation or ticket is closed. It is also called time to resolution (TTR) or mean time to resolution (MTTR) when averaged across many cases.
First Contact Resolution (FCR)
First Contact Resolution (FCR) is the percentage of customer issues fully resolved in a single interaction, with no transfer, callback, or follow-up needed. It measures how often a support team solves a problem the first time the customer reaches out.
Service-Level Agreement (SLA)
A service-level agreement (SLA) is a documented commitment between a service provider and its customers that defines the standard of support to be delivered, such as how fast inquiries are acknowledged and resolved, and how that performance is measured. [1]
Customer Satisfaction Score (CSAT)
Customer Satisfaction Score (CSAT) is a support metric that measures how happy a customer is with a specific interaction, product, or service, usually captured by a short post-interaction survey. It is expressed as the percentage of respondents who rate their experience as satisfied or very satisfied.
Live Chat
Live chat is a real-time, text-based support channel embedded in a website or app that lets visitors message a business and get answers within the same browsing session, without phoning or emailing. It pairs a customer-facing chat window with an agent or bot interface on the other side.
