Missed Lead Cost Calculator
This free speed-to-lead calculator estimates how many jobs — and how much revenue — your current response time costs you each month. It uses conservative multipliers derived from published research: the Lead Response Management study found the odds of qualifying a lead drop about 21x when response time stretches from 5 minutes to 30 minutes. Enter your numbers below — results update as you type.
Your numbers
Your estimate
Enter your leads per month and average job value to see what your current response time is costing you. All results are estimates based on the research cited below.
You are already answering within 5 minutes — the window the research says wins the most jobs. Benchmarks suggest roughly 8 in 10 companies miss that window, so by this model you are not leaving revenue on the table to slow replies.
The next question is whether you can hold that pace at 9pm, on weekends, and in busy season — that is where automation earns its keep.
- Jobs you likely win now (est.)
- Winnable with replies in under 5 min (est.)
- Estimated jobs missed per month
- Revenue left on the table / month
- Revenue left on the table / year
Estimates only, rounded down. Assumptions and sources are listed under “How this is calculated” below.
How this is calculated (assumptions and sources)
The model is simple on purpose: jobs won = leads × 20% baseline win rate × response-time factor. The gap between your factor and the 5-minute factor, times your average job value, is the estimated revenue left on the table.
- Baseline win rate: 20% of leads become paying jobs for a business that replies within 5 minutes. That is a deliberately modest assumption: Invoca's analysis of 60M+ calls found home services converts 46% of phone leads, and Chili Piper's benchmark of ~4M form submissions found 66.7% of qualified leads book a meeting when the response is instant.
- Within 5 minutes: factor 1.0 (the reference point).
- Within 30 minutes: factor 0.6. The Lead Response Management study found qualification odds drop about 21x between 5 and 30 minutes; we conservatively model only 40% fewer won jobs, because qualifying a lead is not the same as winning it.
- Within 2 hours: factor 0.45. Harvard Business Review's audit of 2,241 companies found firms contacting a lead within an hour were nearly 7x more likely to qualify it than firms that waited longer; we model a 55% drop.
- Same day: factor 0.3. Interpolated between the 1–2 hour and 24-hour findings above.
- Next day or later: factor 0.2. The same HBR audit found companies waiting 24+ hours were 60x less likely to qualify a lead than those responding within an hour; we model only 5x fewer won jobs.
Job counts are rounded down to one decimal and dollar figures are rounded down to the nearest dollar. Every output is an estimate — your close rate, market, and follow-up quality all move the real number. The research is covered in depth, with more sources, in our speed-to-lead statistics roundup.
FAQ
How accurate is the missed lead cost calculator?
It is an estimate, not a guarantee. The multipliers are deliberately more conservative than the published research they are based on: studies report qualification odds dropping 21x between a 5-minute and a 30-minute response, while this calculator assumes far smaller drops in actually won jobs. Your real numbers depend on your market, trade, and follow-up quality.
What is a good lead response time for a service business?
Under 5 minutes. The Lead Response Management study found the odds of qualifying a lead drop about 21x when response time goes from 5 to 30 minutes, and a Harvard Business Review audit found companies responding within an hour were nearly 7x more likely to qualify a lead than those that waited longer. Benchmarks show roughly 8 in 10 companies still miss the 5-minute window.
How can I respond to leads in under 5 minutes?
Three common options, in order of cost: turn on push notifications and saved quick replies in your lead apps, have office staff cover the inboxes during work hours, or automate the first reply. An AI auto-responder like LeadWinner answers Yelp and Thumbtack leads in seconds, asks qualifying questions, and follows up — including nights and weekends.
