What is the average lead response time?
The average lead response time in the two largest public audits is 42 hours (Harvard Business Review, 2011) and 4 hours 50 minutes (Chili Piper, 2022); the gap is mostly a difference in who was tested.
| Statistic | Source |
|---|---|
| Harvard Business Review audited 2,241 US companies in 2011 with a web-generated test lead. The average first reply among those answering within 30 days was 42 hours. | Harvard Business Review, 2011 |
| In that 2011 audit, 37% replied within an hour, 16% within one to 24 hours, 24% took longer, and 23% never replied. | Harvard Business Review, 2011 |
| Chili Piper submitted demo requests to B2B software vendors and published a mean reply of 4 hours 50 minutes in February 2022. It published neither a vendor count nor a median, so slow repliers pull that mean up by an unknown amount. | Chili Piper, 2022 |
| Company size moved the 2022 average sharply: vendors with 1 to 10 employees averaged 6 minutes, those with 101 to 250 employees 3 hours 42 minutes, a figure Chili Piper says counts only vendors replying inside two days. | Chili Piper, 2022 |
| Marketing automation was the fastest 2022 category, 37.5% replying inside five minutes. Sales intelligence had 0% inside five minutes and 43% never replying. | Chili Piper, 2022 |
Two things in that 2022 breakdown still surprise me. Ten-person companies beat 200-person companies by a factor of 37, so this is an operating choice rather than a resourcing problem. And the vendors selling sales intelligence were the slowest group, which you could not make up.
Both audits are old enough to read as direction, not as a current benchmark.
How fast does a reply have to be to change the odds?
Speed changes the odds of a lead response inside minutes rather than hours: Professor James Oldroyd's 2007 analysis of InsideSales.com data found the odds of qualifying a prospect are 21 times greater at a five minute reply than at thirty minutes.
| Statistic | Source |
|---|---|
| The odds of a lead becoming qualified are 21 times greater when the first contact attempt comes within 5 minutes rather than 30, from Oldroyd's 2007 analysis, reprinted on page 6 of the 2014 Lead Response Report. | Oldroyd 2007, in InsideSales.com, 2014 |
| The odds of making contact are 100 times greater at 5 minutes than at 30 in that same 2007 analysis. Contact odds and qualification odds are separate measures; the 21x figure is the qualification one. | Oldroyd 2007, in InsideSales.com, 2014 |
| The Lead Response Management study, run with Professor Oldroyd of MIT on InsideSales.com data, covered 15,000+ leads and 100,000+ call attempts at six companies over three years. Contact success fell more than tenfold and qualification success more than sixfold inside the first hour. | Lead Response Management study |
| Harvard Business Review's 2011 companion analysis of 1.25 million leads at 29 B2C and 13 B2B US companies found firms contacting a prospect within an hour were nearly seven times as likely to qualify it as firms trying an hour later. | Harvard Business Review, 2011 |
| The same 2011 analysis found firms replying within an hour were more than 60 times as likely to qualify a lead as firms waiting 24 hours or longer. Qualifying meant a meaningful conversation with a decision maker. | Harvard Business Review, 2011 |
| Calling between 4pm and 6pm produced a 114% higher contact rate than the worst time block, and Thursday beat Tuesday by 49.7%. | Lead Response Management study |
Turn the 21-fold number into a per-minute rate and it stops being a slogan: spread evenly across those 25 minutes, it is 11.5% of your odds gone each minute. The even spread is my assumption, since Oldroyd published only the two end points. Either way, an SLA measured in hours is a rounding error rather than a policy.
Those curves come from 2007 phone data, so the honest question is whether the five minute rule has survived.
What do the speed to lead statistics say about the five minute rule?
The speed to lead statistics behind the five minute rule all trace back to one 2007 dataset, and no public audit since has met that bar at scale: only about 1.3% of the 9,538 companies InsideSales.com tested in 2014 called back inside five minutes.
| Statistic | Source |
|---|---|
| Of 9,538 companies sent a test web lead in 2014, 121 made a first phone response inside five minutes, 1.3% of the sample. | Computed from InsideSales.com, 2014 |
| Only 2,142 of those 9,538 companies, or 22%, responded by phone even once in 2014. | InsideSales.com, 2014 |
| 7% of B2B software vendors answered a demo request in under 60 seconds in February 2022. | Chili Piper, 2022 |
| Marketing automation, the best 2022 category, reached 37.5% inside five minutes, the highest share any public audit has recorded for a named segment. | Chili Piper, 2022 |
| The average B2B software vendor's 4 hour 50 minute reply in 2022 is 58 times the five minute target. | Computed from Chili Piper, 2022 |
The five minute rule is real and almost nobody follows it, a pairing that has held for nearly twenty years. My reading is that the rule is not hard, it is unowned: marketing hands the lead to a CRM, the CRM hands it to a queue, and the queue gets checked when someone gets round to it.
Missing the window is one failure mode; getting no answer is the bigger one.
How many companies never reply to an inbound lead?
Between 23% and 30% of companies never reply to an inbound lead, a share that has stayed stable from Harvard Business Review's 2011 audit to Chili Piper's 2022 one.
| Statistic | Source |
|---|---|
| 23% of the 2,241 US companies audited in 2011 never responded to the test lead at all. | Harvard Business Review, 2011 |
| Nearly 30% of B2B software vendors had not replied to a demo request seven business days later, measured in February 2022. | Chili Piper, 2022 |
| In the sales intelligence category, 43% of vendors never replied in the 2022 audit. | Chili Piper, 2022 |
| The average cost per lead from Google search ads is $66.69, from 13,474 campaigns running April 2025 to March 2026. | WordStream / LocaliQ, 2026 |
| Sales representatives spend 60% of their time on tasks other than selling. | Salesforce, 2026 |
Put the no-reply rate next to the paid media price and the waste is easy to size. At $66.69 a lead and a quarter going unanswered, a team buying 500 leads a month pays roughly $8,300 for conversations that never start. Nobody signs that off, because it never appears as a line item.
Teams that do answer still have to reach a channel the buyer picks up.
Which response channels still get answered?
Email is how most companies reply to a web lead, the phone is what the response curves reward, and the 2026 answer-rate data widens that gap: 86% of calls from an unknown number go unanswered (Hiya, 2026).
| Statistic | Source |
|---|---|
| 86% of calls from an unknown number go unanswered, from a survey of 12,000+ consumers across six countries. | Hiya, 2026 |
| 70% of first responses to a web lead came by email in 2014 and 30% by phone, of which 25 points were voicemail rather than a live call. | InsideSales.com, 2014 |
| 18.6% of cold calls connect with the intended prospect, from Sopro's State of Prospecting 2026 across 151 million outreach points. | Sopro, 2026 |
| Follow-up messages two to six produce 58.6% of all replies, against 41.4% for the first message. | Sopro, 2026 |
| 56.3% of legal services conversions and 52.6% of professional services conversions arrive as phone calls rather than form fills, from 110 million sessions. | Ruler Analytics, 2026 |
| The average website conversion rate across 13 industries is 5.13%, with software at 7.6% and legal at 7.9%. | Ruler Analytics, 2026 |
The 86% unanswered figure changes tactics as much as SLAs. A call-back inside five minutes from a number the buyer does not recognise is a coin flip, so the fast reply has to land on the channel the buyer just used. Speed without recognition reaches voicemail sooner.
Answering fast matters because of what happens next in the buyer's head.
Does the vendor who answers first win the deal?
Usually, yes: 6sense found in 2025 that buyers bought from the vendor they spoke to first 77% of the time, across nearly 4,000 buyer responses.
| Statistic | Source |
|---|---|
| Buyers bought from the vendor they spoke to first 77.0% of the time in 6sense's main 2025 survey (n=3,744), 81% in a supplemental one (n=766). | 6sense, 2025 |
| Buyers initiated 79% of engagements with vendors in 2025, down from 82% the year before. | 6sense, 2025 |
| First contact with a seller moved from 69% of the buying journey to 61% in 2025, roughly six to seven weeks earlier. | 6sense, 2025 |
| The average B2B buying cycle shortened from 11.3 months in 2024 to 10.1 months in 2025. | 6sense, 2025 |
| The first vendor conversation is worth 3.3 times all other shortlisted vendors combined. | Computed from 6sense, 2025 |
Read the 77% carefully before building a strategy on it. Buyers usually talk to their favourite first, so being first is partly an effect of already being preferred. The form fill is the finish line of a race that ran without you. Our dark funnel statistics page reaches the same lesson from the other direction.
If the first conversation carries that weight, the next question is what buyers count as an acceptable wait.
What do buyers expect from response speed in 2026?
Buyers in 2026 treat speed as a purchase criterion rather than a courtesy: 86% of consumers told Zendesk that responsiveness and accurate resolution strongly influence what they buy.
| Statistic | Source |
|---|---|
| 86% of consumers say responsiveness and accurate resolution strongly influence their purchases, from 11,000+ respondents across 22 countries surveyed in June 2025. | Zendesk, 2026 |
| 85% of CX leaders say customers leave a brand that cannot resolve an issue on first contact. | Zendesk, 2026 |
| 74% of consumers expect support to be available around the clock. | Zendesk, 2026 |
| 63% of consumers believe an AI agent answers faster than a human, and 72% would pick one if that guaranteed a faster fix. Survey of 4,800 consumers and 457 business leaders, 15 countries, August to October 2025. | Twilio, 2026 |
| 90% of business leaders believe customers are satisfied with AI agent interactions, against 59% of consumers, a 31 point gap. | Twilio, 2026 |
| 46% of business buyers would work with an AI agent to get faster service. | Salesforce, 2026 |
| 30% of customers with a bad experience switch brands without telling anyone, from 20,000 consumers across 14 countries. | Qualtrics, 2026 |
| 68% of support teams say AI has changed their response times, from Intercom's survey of 2,000+ service professionals. | Intercom, 2024 |
The Twilio gap is the number I would pin up. Nine in ten leaders think the automated experience is landing; six in ten customers agree. Speed bought with an AI agent only counts if the answer is right, and Qualtrics' 30% who leave silently will not tell you which half you got wrong.
Buyer expectations explain the demand for speed; capacity explains why so few teams supply it.
Why do most teams miss the window?
Most teams miss the five minute window for structural reasons: The Bridge Group's 2025 survey of 351 B2B companies found sales development reps log 112 activities a day for 4.1 quality conversations.
| Statistic | Source |
|---|---|
| SDRs log 112 activities a day and reach 4.1 quality conversations, across 351 B2B companies surveyed in 2025. | The Bridge Group, 2025 |
| Phone-centric SDR teams make 56 dials a day and reach 4.6 quality conversations. | The Bridge Group, 2025 |
A rep holding four real conversations out of 112 attempts has no spare attention for an inbound form that landed nine minutes ago. Speed to lead is a queueing problem, and the fix is routing and alerting rather than effort. The same misread shows up in channel budgets, which is why our inbound vs outbound marketing statistics page lands on process rather than spend.
How we calculated the original numbers
These four figures appear nowhere else. Here is the arithmetic, so you can check it or change the inputs.
- 11.5% of qualification odds lost per minute of delay. Oldroyd's 2007 analysis of InsideSales.com data, reprinted on page 6 of the 2014 Lead Response Report, found the odds of qualifying a lead are 21 times greater at a 5 minute contact attempt than at 30 minutes. That is 21x across 25 minutes, so a constant per-minute multiplier is 21^(1/25) = 1.1295. Each minute keeps 1/1.1295 = 88.54% of the previous minute's odds, a loss of 11.46%, and 0.8854 compounded 25 times returns 1/21. The constant rate is my assumption, not Oldroyd's: he published two end points, and a real decay curve is usually steeper at the start.
- 58x: how much slower the average vendor is than the five minute target. Chili Piper published a mean reply of 4 hours 50 minutes in February 2022, or 290 minutes. 290 / 5 = 58. There is no published median or vendor count, so this compares a mean against the target.
- 1.3% of companies called back inside five minutes. InsideSales.com's 2014 report tested 9,538 companies with a web lead and plotted first phone response times; 121 fell in the 0 to 5 minute bucket. 121 / 9,538 = 1.27%. Both inputs are from 2014, so read it as a historical floor.
- 3.3x: the value of the first conversation. 6sense found in 2025 that buyers bought from the vendor they spoke to first 77% of the time (n=3,744), leaving 23% for every other shortlisted vendor combined. 77 / 23 = 3.35.
What the 2026 numbers say
The canonical research is old and nobody has replaced it. Harvard Business Review's 2011 audit and Oldroyd's 2007 curves are still the only large published response curves with a stated method. Everything newer is a vendor audit with an undisclosed sample. Anyone quoting "78% of buyers choose the vendor who responds first" without a link is repeating folklore.
The failure rate has not moved in a decade. 23% never replied in 2011, close to 30% in 2022. Two samples, two methods, one stubborn quarter of inbound demand going unanswered while the same companies pay $66.69 a lead for it.
The 2026 twist is recognition, not speed. With 86% of unknown calls unanswered (Hiya, 2026) and buyers arriving 61% of the way through their journey (6sense, 2025), a fast reply on an unrecognised channel is close to worthless. Answer in the thread the buyer opened, in minutes, with the context attached. That is a routing and attribution problem before it is a sales problem, which is why our marketing attribution statistics page belongs next to this one. The full set sits in the statistics hub.
FAQ
What is the average lead response time?
The average first reply to a web lead was 42 hours in Harvard Business Review's 2011 audit of 2,241 US companies, and 4 hours 50 minutes in Chili Piper's February 2022 audit of B2B software vendors. Neither publisher gave a median, and both means are pulled up by very slow responders.
What do the speed to lead statistics say about responding in five minutes?
The speed to lead statistics behind the five minute rule come from Oldroyd's 2007 analysis of InsideSales.com data, which found the odds of qualifying a prospect are 21 times greater at a 5 minute reply than at 30. Almost nobody meets it: only 1.3% of the 9,538 companies tested in 2014 called back that fast.
How much does every minute of delay cost?
About 11.5% of the odds of qualifying the lead, computed here by spreading Oldroyd's 2007 21-fold drop evenly across the 25 minutes between a 5 and a 30 minute reply. The even spread is an assumption, not a measured curve. On that basis, ten minutes of delay leaves roughly a third of your minute-one odds.
How many companies never respond to inbound leads?
23% of the 2,241 US companies Harvard Business Review audited in 2011 never responded, and nearly 30% of B2B software vendors had not replied seven business days later in Chili Piper's 2022 audit. In sales intelligence that reached 43%.
Does the first vendor to respond win the deal?
Buyers bought from the vendor they spoke to first 77% of the time, in 6sense's 2025 B2B Buyer Experience Report (n=3,744). Buyers usually approach their favourite first, so read this as evidence that preference is set before the form fill rather than proof that speed alone wins.
How fast do buyers expect a reply in 2026?
86% of consumers say responsiveness and accurate resolution strongly influence their purchases, from Zendesk's survey of 11,000+ people across 22 countries (2026). Twilio found in 2026 that 72% would pick an AI agent over a human for a faster fix.

Methodology. Numbers were collected in September 2026 and checked against the original publisher's page, report or PDF, never against statistics roundups. The canonical response curves date from 2007 and 2011 and the largest audit with a published sample from 2014, so each carries its year wherever it is used. Vendor claims without a stated sample or method were excluded; where Chili Piper published a method but no sample size or median (2022) the row says so. Untraceable claims, including the "78% of buyers choose the vendor who responds first" figure, were left out. Last updated 21 September 2026.
