Lead response time statistics (2026): the numbers with real sources

1. The Harvard Business Review audit (2011)

The most credible number set in this category. Researchers James Oldroyd, Kristina McElheran and David Elkington audited 2,241 US companies by submitting a test lead to each and timing the response. Their findings:

• 37% responded within an hour.
• 16% responded within one to 24 hours.
• 24% took more than 24 hours.
• 23% never responded at all.
• Average response time among companies that did respond: 42 hours.
• Firms that tried to contact a lead within an hour were nearly 7 times more likely to qualify it than firms that waited even an hour longer, and more than 60 times more likely than firms that waited 24 hours or more.

Source: Oldroyd, McElheran, Elkington, "The Short Life of Online Sales Leads," Harvard Business Review, March 2011. hbr.org (paywalled). Secondary summary: leadgen-economy.com.

Why it matters: it is an audit of real companies, not a vendor's customer data, and it was published in a peer-reviewed-adjacent outlet. It is also fifteen years old. Nothing since has contradicted it, but treat it as a floor, not a current benchmark.

2. The Lead Response Management study (2007)

This is the source of the "5 minutes versus 30 minutes" figures. InsideSales.com (now XANT) and Oldroyd analyzed three years of data from six companies: more than 15,000 leads and 100,000 call attempts. Findings:

• The odds of making contact with a lead were 100 times higher when the first call came within 5 minutes rather than 30.
• The odds of qualifying the lead were 21 times higher at 5 minutes versus 30.
• Contact odds fell sharply after the first 5 minutes and kept falling through the first hour.

This study is frequently labeled an "MIT study." It is not one. Oldroyd was affiliated with MIT Sloan at the time, but the data came from a software vendor's customers. Cite it as the Lead Response Management study, with that caveat.

3. Velocify, "The Ultimate Contact Strategy"

Velocify (a lead-management vendor, later part of Ellie Mae and ICE) analyzed 3.5 million leads across its customers. The numbers:

• Calling within one minute of the inquiry produced a 391% lift in conversion compared with the baseline.
• The lift dropped to 98% by the three-minute mark and to 17% after a day.
• The best-performing contact pattern was six call attempts plus five emails over the first few weeks.

4. Drift's lead response audit

Drift secret-shopped 433 companies by filling out their forms and timing the reply. Only 7% responded within 5 minutes. 55% had not responded within five business days. The year is disputed (2017 is the most common citation; some blogs say 2021 or 2023), so cite it as "Drift's audit of 433 companies" without a year unless you can confirm it.

5. Workato's 114-company test

A more recent independent test: Workato submitted leads to 114 B2B companies and measured time to first response. It is useful mainly because it is recent and not from a lead-response vendor. Read the method before quoting a headline number from it.

6. After-hours and missed calls

• Podium's home-services division reports that 40% of service calls come in after hours. Vendor number, but consistent with what we see on our own painting and bath lead forms.
• Invoca's analysis of 70 million tracked calls found 44% went unanswered.
• The widely quoted "62% of calls to small businesses go unanswered" traces to an 85-business sample by 411 Locals. Label it small-sample if you use it.

7. The number you should stop citing

"78% of customers buy from the company that responds first." It appears on hundreds of sales pages, usually attributed to a "Lead Connect survey" that nobody can produce. Podium uses a version of it ("78% of homeowners go with whoever responds first"). If you must use it, write "Podium reports" and nothing stronger. A better substitute is 6sense's 2025 finding that the vendor contacted first wins roughly 80% of the time, or simply HBR's 7x figure. We traced the 78% stat here.

8. The compliance number that changed in 2024

On February 8, 2024, the FCC issued Declaratory Ruling 24-17, confirming that AI-generated voices are "artificial" under the TCPA. Any AI voice call to a cell phone needs prior express consent. Response-time statistics are only useful if the fast response is legal. The TCPA in plain English for contractors.

How to use these numbers

Pick one from each category: an audit (HBR), a contact-odds study (Lead Response Management), a conversion-lift analysis (Velocify), and a current benchmark (Drift or Workato). Cite the source name and year every time. Do not add a vendor's unverifiable claim to make the slide look better; the verifiable numbers are already dramatic. Our own system answers every lead by email in seconds and, with consent, by AI voice in about a minute, which is how we get to the left side of every chart above. What speed to lead means and how it works.
