How fast should you respond to a lead from your website, how many businesses never respond at all, and how many calls go unanswered? This page collects the lead response numbers that can be traced to an original study: the MIT lead response research, secret-shopper audits, call-tracking data from Invoca and CallRail, and consumer surveys.
Each figure shows its source, year and method. Much of the recent data comes from companies that sell call, text or chat software, so we name the publisher on every line. Several of the most quoted speed-to-lead numbers can't be traced to a source at all; they're listed at the end. Nothing here comes from LeadDuo or customer data.
What you’ll get from this guide
- Calling a web lead within 5 minutes instead of 30 made reaching them about 100 times more likely, and qualifying them 21 times more likely (InsideSales.com/MIT study, 2007, older study).
- 56% of U.S. consumers expect a reply within an hour of submitting a form, only 36% get one, and 79% say they'll switch to a competitor that responds faster (Invoca survey of 693 U.S. consumers, 2026).
- Only 52% of callers to home services businesses speak with a person (Invoca call data, 2026).
- Only 48% of home services businesses respond to after-hours inquiries right away; 34% wait until the next morning (CallRail survey, 2025).
- In a secret-shopper test of 9,538 companies, 47% never responded to a web lead (InsideSales.com, 2014, older study).

Speed to lead
| Finding | Figure | How it was measured | Source |
|---|---|---|---|
| Odds of contacting a web lead: called in 5 minutes vs 30 minutes | About 100× higher | 3 years of data at 6 companies, 15,000+ web leads, 100,000+ call attempts. Measures contact, not sales. Older study | InsideSales.com/MIT, 2007 |
| Odds of qualifying a lead: 5 minutes vs 30 minutes | 21× higher | Same study | InsideSales.com/MIT, 2007 |
| Odds of contact over the first hour | Fall more than 10× | Same study | InsideSales.com/MIT, 2007 |
| Conversion when called within 1 minute vs later | 391% more likely to convert | Velocify customer data, "millions of lead records"; no period given. Vendor, older | Velocify, 2016 |
The MIT figure compares 5 minutes with 30 minutes and measures reaching the lead, not closing the sale. It is often misquoted as "5 minutes vs an hour" or attributed to Harvard.
How often businesses respond slowly or never
| Finding | Figure | How it was measured | Source |
|---|---|---|---|
| Companies that never responded to a test web lead | 47% (4,472 of 9,538) | Secret-shopper web-form leads, submitted during business hours, 2013. Older study | InsideSales.com, 2014 |
| Median time to first call among companies that called back | 3 hours 8 minutes | Same audit; companies that responded by phone | InsideSales.com, 2014 |
| Consumers who get a reply to a form within an hour | 36% | Survey of 693 U.S. consumers who made a high-stakes purchase, May 2026 | Invoca, 2026 |
| Home service companies that never responded to a request within 5 days | 40% | Secret-shopper requests to 466 U.S. home service companies. Older study (about 2018) | Valve+Meter |
| Home services businesses that answer after-hours inquiries right away / next morning | 48% / 34% | CallRail survey of U.S. home services businesses; sample size not disclosed | CallRail, 2025 |
Missed and unanswered calls
| Finding | Figure | How it was measured | Source |
|---|---|---|---|
| Callers who speak with a person, all industries / home services | 56% / 52% | Invoca platform data, 70M+ calls across 10 industries | Invoca, 2026 |
| Inbound calls missed: home services / dental / physical therapy | 27% / 27% / 28% | Invoca platform call analysis; sample size not given | Invoca, 2023 |
| Missed call rate: healthcare / legal / home services / real estate | 32% / 28% / 14% / 9% | 1.1 million de-identified conversations from CallRail customers | CallRail, 2025 |
| Calls to small businesses answered live | 37.8% (another 37.8% went to voicemail; 24.3% got no response) | Calls to 85 businesses in 58 industries over 30 days. Small, older study | 411 Locals, 2016 |
Invoca and CallRail define a missed call differently, which is why their home services figures (27% and 14%) don't match. Compare industries within one source, not across sources.
What customers expect

|---|---|---|---|
| U.S. consumers who expect a reply within an hour of submitting a form | 56% | 693 U.S. consumers, May 2026 | Invoca, 2026 |
| Who would switch to a competitor that responds faster | 79% | Same survey | Invoca, 2026 |
| Consumers who expect a reply to a text within an hour | Nearly 70% | 959 U.S. consumers, January 2026; EZ Texting sells business texting | EZ Texting, 2026 |

| Consumers who seek out businesses offering text or chat instead of a call | 46% | 1,304 consumers in the U.S., Canada and Australia, Sept 2021 | Podium, 2021 |

After-hours inquiries
- 48% of appointments booked through Square Appointments were made outside business hours, after the business had closed (Square, 2018). Older study, and Square doesn't state its method or period. It is the only after-hours share we could trace to a primary source.
- 34% of home services businesses wait until the next morning to respond to after-hours inquiries (CallRail, 2025).
- Widely shared figures for the share of leads that arrive after hours (from 34% to 67%) contradict each other and none traced back to a published report, so we don't use them.
What the numbers mean for your website
- Every study points the same way: the first business to reply well has the advantage, and most businesses are slower than their customers expect.
- Cover the hours you're closed. Bookings and questions keep coming after closing time, and a third of home services businesses don't reply until the next morning.
- Give visitors a way to get an answer without a phone call. Many consumers look for text or chat first.
- Work out what slow replies cost you with the free website leads lost calculator, and write the questions your website chat should ask with the free chat questions generator.
Numbers we couldn't verify
These are on almost every speed-to-lead page. We tried to trace each one to an original study and couldn't, so they aren't used here:
- "78% of customers buy from the first company to respond." No study, year, sample or link has been found for it.
- "35–50% of sales go to the vendor that responds first." The earliest copies cite a sales software company with no link, and no document from that company contains it.
- "Responding in 5 minutes makes you 100 times more likely to connect than after an hour." A distortion of the 2007 MIT study, which compared 5 with 30 minutes.
- "Firms that responded within an hour were 7 times more likely to qualify the lead." From a 2011 Harvard Business Review article we couldn't open to confirm the wording.
- "85% of callers who reach voicemail never call back." Often credited to the 411 Locals study, but it isn't in it.
- "81% of people abandon a form after starting it." Reported from a 2018 survey whose source page we couldn't open.
Methodology and sources
Every figure was checked against its original source on October 31, 2026. Where the original lives only as a press release or a hosted copy, the link goes to that release or copy and the line says so. Vendor studies are named. Older studies are marked with their year. Nothing is projected or estimated by LeadDuo.
