Lead response time is how long a new lead waits between reaching out (a web form, a call, a chat) and your team's first call. A good lead response time is under five minutes, for every lead, at any hour of the day. The Lead Response Management study found that a call within 5 minutes reaches and qualifies far more leads than one at 30.
The catch: an average can't tell you whether you hit that. Take a made-up week where your team called 10 leads. The average wait was 118 minutes. The median lead (the middle one) waited 5. Same week, same calls, and neither number counts the lead nobody called at all. So you'll report three numbers, not one.
How do you measure lead response time?
The formula: for each lead, take the time of your team's first call and subtract the time the lead arrived. Then take the median of those times across the week. Four choices decide whether that number is honest.
1. Start the clock when the lead arrives. Use the time the form was submitted, not the time a rep opened the lead. Everything before a rep sees the lead (getting it into the CRM, routing it, someone noticing it) is lead processing time, and the lead waits through every minute of it. If all your CRM has is the time it created the lead, use that, but know it leaves out the time before the lead got there.
2. Pick your stop point and name it. There are two useful ones:
- Time to first call: the first call to the lead, whether a rep or an AI placed it. An automatic "thanks, we'll be in touch" text doesn't count.
- Time to first conversation: the first time someone actually spoke with the lead.
Report time to first call, because you control it. You don't control whether the lead picks up. But check the other one too. A team can make its first call in 30 seconds and still take hours to reach anyone, because a call that goes to voicemail counts as a call.
3. Report the median next to the share called within 5 minutes. A few leads called the next morning drag the average up. We don't quote an average for Callingly's own call data either. In the made-up week, the 10 leads waited 1, 2, 2, 3, 4, 6, 9, 15, 240 and 900 minutes for their first call.
The median has the opposite problem: it hides the slow end. Two of those leads waited four hours or more, and the median wouldn't move if they'd waited a week. So put the share called within 5 minutes (here, 5 of 10) next to it. You're aiming for every lead, not the middle one.
4. Count the leads nobody called separately. A lead that never got a call has no response time, so it quietly drops out of the median. Keep it in the share, though: if an 11th lead came in that week and nobody called it, 5 of 11 got a call within 5 minutes, not 5 of 10. Then report it on its own: "1 of 11 leads never got a call" is the line you most need to see.
So each week, report three numbers: the median time to first call, the share of leads called within 5 minutes, and the number of leads never called.
Then split them by when the lead came in: business hours versus evenings and weekends. If your daytime median is 2 minutes and your after-hours median is 11 hours, you don't have a speed problem. You have a coverage problem.
What is a good lead response time?
Under five minutes for the first call, and under one if you can. Here's what each study found at each response time:
| Response time | What the study found | Source |
|---|---|---|
| Within 1 minute | Calling a new lead within a minute raised conversion by 391%. | Velocify, The Ultimate Contact Strategy (nearly 3.5 million leads, 400+ companies) |
| 5 vs. 10 minutes | 4 times the odds of qualifying the lead. | Lead Response Management study (2007) |
| 5 vs. 30 minutes | 100 times the odds of reaching the lead, 21 times the odds of qualifying them. | Lead Response Management study (2007) |
| Within an hour vs. later | Nearly 7 times as likely to qualify the lead as a company that tried an hour later, and more than 60 times as likely as one that waited 24 hours or longer. | Harvard Business Review (2011) |
Each study measured something different (reaching the lead, qualifying them or converting them), so the multiples don't stack. They all point the same way. For the story behind the five-minute number, read the 5-minute rule.
Most companies don't come close:
- Across industries: the Harvard Business Review researchers audited 2,241 U.S. companies. Only 37% replied to a web lead within an hour, 24% took more than a day, and 23% never replied at all. Among those that did reply, the average wait was 42 hours.
- In real estate: the WAV Group posed as a home buyer to 384 brokers in 11 states (2014). 48% of the inquiries never got a reply, and the average response took 917 minutes, about 15 hours.

How do you cut your lead response time?
1. Send every lead source to one place
Leads come in through web forms, Facebook Lead Ads, Zillow and other portals, chat, and your phone line. When each one lands in a different inbox, somebody has to check them all, and the lead that arrives during a meeting waits. Route every source into your CRM or lead router so the clock starts in one place and one process takes over. Callingly connects to CRMs like Follow Up Boss, HubSpot and Salesforce natively, and to 1,000+ other apps through Zapier.
2. Make the first call automatic
A rep who has to notice a lead, open it and dial will never be as fast as a call that starts on its own. With Callingly, the AI Agent calls new leads within seconds while your team is open and has a rep free, and it can text them in the same sequence. Its job is the first minute: reach the lead, ask your qualifying questions, and warm-transfer them to one of your reps. The AI warms them up. Your rep closes.
3. Cover evenings and weekends
A lead who fills out your form at 7 p.m. on a Friday still wants a call. Either staff those hours or let automation make the first call. Depending on your settings, Callingly's AI Agent can make that first call after hours and offer the lead a callback at a time they pick.
4. Follow up on a schedule, not from memory
A fast first call only helps if it reaches someone, and plenty of first calls go to voicemail. The fix is a followup sequence: a set number of calls and texts at set times over the first few days. Callingly runs the call and SMS sequence you set up, so nobody has to remember to try again.
5. Write the target down and check it every week
Make the target a rule everyone can see: every lead gets a first call within 5 minutes. That's your lead response SLA, the promise your team keeps. Then put the three weekly numbers in front of the team. Look at the slowest leads one by one and ask what happened: wrong routing, a missed shift, a source that isn't connected.
