Lead response time & SLA calculator
The five-minute rule: first human or agent reply. Clock starts at form submit. Track minutes left on a live lead, or compare your average lead response time with your SLA target.
Measure lead response time against your SLA
New leads expect a fast first reply, and a lead that waits too long often moves on. This lead response time and SLA calculator shows how many minutes are left on a live lead and whether your average lead response time meets your first-response target.
How to use the lead response time calculator
Set your target in minutes. For a live lead, enter the minutes since the form was submitted to see the time left before breach. To check your team overall, enter your average lead response time in minutes or hours below and compare it with the same target.
3.0 min
Remaining until breach.
Average lead response time vs target
Enter your current average (or historical) first-response time. It is compared with the target above.
Misses target
Average 30.0 min vs target 5.0 min — gap +25.0 min (500% over target).
What your result means
Minutes left above zero means the live lead is still inside your SLA; below zero means it has breached and should be escalated. For your average, “Meets target” means your average lead response time is at or under the target, and the gap shows how many minutes — and what percentage — you are over or under it.
FAQ
What is lead response time?
Lead response time is how long it takes from the moment a lead submits a form or sends a message to the first reply from a person or an AI agent. This calculator starts the clock at form submit and stops it at that first reply.
What is a lead response SLA?
A lead response SLA is the first-response target your team commits to — for example 5 or 15 minutes from form submit. The calculator measures a live lead, or your average lead response time, against that target.
How does this lead response time calculator work?
It has two parts. For a live lead, minutes left is the target minus the minutes elapsed; below zero the lead has breached the SLA. For your average lead response time, enter it in minutes or hours and the calculator converts it to minutes and shows whether it meets or misses the target, the gap in minutes, and the percentage over or under the target.
What is the five-minute rule for lead response?
It is a common rule of thumb that new inbound leads should get a first reply within five minutes of submitting a form, while they are still engaged. That is why the calculator starts with a 5-minute target — change it to whatever SLA your team has agreed.
How can an agentic workflow keep lead response time within SLA?
An AI agent can reply as soon as the form is submitted, ask the first qualifying questions, and book a call or route the lead to the right person. The workflow watches the SLA clock and escalates to a person before a lead breaches, so your team only picks up the leads that need them.
Need every new lead answered within SLA?
GoWith agentic builds answer new leads straight away and hand off to your team when a person is needed. See all free tools, the follow-up cadence planner, the BANT lead scorer, and the no-show risk calculator.
