    Speed to lead statistics: how fast you need to respond

    The most quoted numbers on lead response time, traced back to the studies they came from and what each one actually measured. Then what it takes to reply in seconds instead of hours.

    The short answer

    Respond within 5 minutes. In the Lead Response Management study, the odds of qualifying a web lead were 21 times higher when the first call came within 5 minutes than at 30 minutes, and they fell 4 times over just minutes 5 to 10. Most companies are far slower: when 9,538 companies were sent a test web lead in 2014, 47% never responded, and the median first phone call came 3 hours and 8 minutes later.

    Where they come from

    The studies behind the numbers

    Most speed-to-lead numbers you'll see online go back to these three. Here's who ran each one and what it measured.

    The Lead Response Management Study

    Dr. James Oldroyd (then at MIT) with InsideSales.com, 2007

    3 years of data from 6 companies: more than 15,000 web leads and 100,000 call attempts.

    • The odds of qualifying a lead fell 21 times when the first call came at 30 minutes instead of 5.
    • The odds of qualifying fell 4 times from minute 5 to minute 10.
    • Contact rates were 100 times higher for calls within 5 minutes than at 30.
    • Wednesday and Thursday were the best days to call; 4 to 6 PM was the best time to reach people, and 8 to 9 AM and 4 to 5 PM the best to qualify them.

    It measured phone calls to web leads. “Contact” meant a conversation of a set length and “qualify” meant the lead agreed to move forward, often by booking a meeting; it didn't measure closed sales. It was run with a company that sells calling software.

    “The Short Life of Online Sales Leads”

    James B. Oldroyd, Kristina McElheran and David Elkington, Harvard Business Review, March 2011

    An audit that sent a web lead to 2,241 US companies, plus an analysis of 1.25 million leads handled by 42 companies (29 selling to consumers, 13 to businesses).

    • 37% of companies responded within an hour, 16% within 1 to 24 hours, 24% took longer, and 23% never responded.
    • Among companies that responded within 30 days, the average response took 42 hours.
    • Companies that reached out within an hour were nearly 7 times as likely to qualify the lead as those that waited even an hour more, and over 60 times as likely as those that waited 24 hours or longer.

    “Qualify” meant a meaningful conversation with a decision maker. The research came before most businesses texted their leads.

    2014 Lead Response Report

    InsideSales.com, 2014

    Test web leads submitted to 9,538 companies during business hours (8 AM to 5 PM in each company's time zone), with every reply tracked.

    • 47% of companies (4,472) never responded, and another 24% responded only once.
    • Only 22% ever called the lead; 70% of first responses were emails.
    • Among companies that called, the median first call came after 3 hours and 8 minutes; small companies (under 300 employees) that called took a median 2 hours and 22 minutes.
    • Of the companies that called, 36% called only once.

    Numbers we left out

    • “The 100x stat is from Harvard” or “from MIT”It's from the 2007 Lead Response Management study, run by an MIT professor with InsideSales.com. The Harvard Business Review article is a separate study with its own numbers (7x and 60x).
    • “78% of customers buy from the first company to respond”Widely quoted, but we couldn't find the original study or how it was measured, so it isn't on this page.
    • “62% of calls to small businesses go unanswered”It traces to a small study of 85 businesses that we couldn't read in full. We show our own call data below instead.

    First-party data

    What we see on Zuops

    Measured across the businesses that use Zuops, from our own records. They describe Zuops customers, not every business, and we'll keep them current.

    • Under 10 sec

      median time from a new lead to its first automatic text

      About 13,000 leads, in the 120 days to October 19, 2026.

    • 43%

      of inbound calls went unanswered at businesses without the AI receptionist

      Voicemail, no answer, busy or missed: 1,337 calls to 117 businesses, August 4 to October 19, 2026.

    • 26%

      went unanswered at businesses that use the AI receptionist

      660 calls to 50 businesses, same period. Many turn it on only after hours.

    What to do about it

    How to respond to leads in seconds

    1. 1

      Text first, the second the lead arrives

      A text can go out before anyone on your team sees the lead, and the lead can answer when it suits them. Call after, if they want to talk.

    2. 2

      Answer every call, or text back the ones you miss

      A missed call is a lead waiting for a reply. Text the caller back right away, or have an AI receptionist pick up when nobody else can.

    3. 3

      Send leads to someone who's free

      Round robin routing and a phone alert for each new lead stop leads from sitting in a shared inbox.

    4. 4

      Follow up more than once

      In the 2014 report, 24% of companies responded only once, and a third of those that called gave up after one call. Plan a few texts and calls over the first days.

    5. 5

      Call when people pick up

      The 2007 study found 4 to 6 PM the best time to reach people and Wednesday and Thursday the best days.

    FAQ

    Speed to lead questions

    What is speed to lead?

    The time between a lead reaching out (a form, a call, a message) and your first reply. The shorter it is, the more of those leads you reach and qualify.

    How fast should you respond to a lead?

    Within 5 minutes. In the Lead Response Management study, the odds of qualifying a lead fell 21 times between a first call at 5 minutes and one at 30 minutes, and 4 times between minute 5 and minute 10.

    What is the average lead response time?

    In Harvard Business Review's audit of 2,241 US companies, the average was 42 hours among those that replied within 30 days, and 23% never replied. In the 2014 test of 9,538 companies, 47% never responded and the median first phone call came after 3 hours and 8 minutes.

    Does a text count, or do I have to call?

    The studies measured phone calls. A text is the easiest way to be first because it can go out the moment the lead arrives, at any hour; a call can follow. On Zuops, the AI texts first, keeps the conversation going and books the appointment.

    What about phone calls I miss?

    They're leads waiting for a reply too. At Zuops businesses without the AI receptionist, 43% of inbound calls weren't answered live (August to October 2026). A missed-call text back or an AI receptionist covers them; the missed-call calculator shows what they're worth to you.

    Where does the “100 times” number come from?

    From the 2007 Lead Response Management study by Dr. James Oldroyd and InsideSales.com: contact rates for calls within 5 minutes were 100 times those at 30 minutes. It's often credited to Harvard or MIT.
