Support reply-time calculator

See your realistic first-response time and the staffing it takes to hit your SLA.

A support reply-time calculator estimates how quickly your team can send a first response given your ticket volume, staffing, and coverage hours. First response time is the gap between a customer writing in and a human replying — the metric customers feel most. Enter your numbers below to see your realistic first-response time, how busy your team is, and how many agents it takes to hit a target SLA. It uses a standard queue model: as your team gets busier and nears full capacity, wait times rise sharply. AI-drafted replies cut the minutes spent per ticket, so the same team hits a faster response time without hiring.
