Enter four numbers and see the revenue you are leaving on the table, plus what you could recover by answering every lead in under 60 seconds.
Enter your name and work email to unlock the calculator. Takes 5 seconds.
This calculator sizes the revenue gap between your current response time and instant response. It is a planning estimate, not a guarantee, and every number is yours to change.
The model. Research on lead response shows the odds of contacting and qualifying a lead fall sharply as response time grows. We express this as a reachability factor: at instant response you reach essentially all of the leads you otherwise could, and at slower tiers you reach proportionally fewer while their intent is still live.
| Response time | Reachability factor used |
|---|---|
| Under 5 minutes | 1.00 |
| 5 to 30 minutes | 0.72 |
| 30 to 60 minutes | 0.55 |
| 1 to 24 hours | 0.40 |
| More than 24 hours | 0.25 |
The math. Your entered close rate reflects your current speed. Current revenue is leads × close rate × deal value. The instant-response scenario scales your close rate up by the reachability gap (close rate ÷ current factor), capped at a realistic ceiling so it never implies an unrealistic close rate. Lost revenue is the difference between the two. Recovered revenue per year is that monthly gap times twelve.
Because it is directional, treat the output as the size of the opportunity. On a call we model your real pipeline numbers instead of these defaults.
The reachability factors are grounded in widely cited lead-response research:
Individual results depend on your lead volume, offer, market and sales execution. If you find a number on this page you cannot verify at the linked source, email us and we will either evidence it or remove it.
Close rate. Almost everyone enters the wrong one, and it is the input the whole model swings on.
Your close rate here is jobs won divided by leads received, not jobs won divided by conversations had. Those two numbers can be a factor of three apart. If you speak to half your leads and close a third of those, your conversation close rate is 33% but the number this calculator wants is roughly 17%. Enter the conversation number and the output will flatter you, which defeats the point of running it.
The reason it matters is that speed does not make you better on the phone. It does not improve your pitch, your pricing or your rapport. What it changes is how many of the people who raised a hand ever end up in a conversation with you at all. So the model holds your selling ability constant and moves only the contact rate, which is the honest way to isolate what response time is actually worth.
Most people look at the annual figure, wince, and close the tab. Here is the more useful sequence.
It only counts leads you know about. The larger and quieter cost is the caller who rang while your hands were full, did not leave a voicemail, and never appeared in any of your systems. You cannot enter a number you never saw, so this model ignores them entirely, which means the real gap is wider than the figure on screen.
It also ignores the compounding effects: the referrals a won job would have generated, the review she would have left, and the fact that the competitor who answered first now owns the relationship for the next replacement cycle. None of that is in the arithmetic. Treat the output as a floor.
Because we send you the result and, honestly, because it is how we find out who to talk to. You can unsubscribe from the first message. We do not sell the address on, and we do not run you through an eleven-step sequence.
They are our estimate, calibrated to the research linked above. The studies establish that the drop-off is steep and front-loaded into the first half hour. Turning that into a single factor per tier is a modeling choice we made, and we would rather label it plainly than dress an assumption up as a finding.
The response-time effect holds, because the research is about reaching and qualifying a lead rather than closing one. What breaks is the annualization: if your cycle runs nine months, a monthly gap times twelve is not a clean read of this year. Use the per-lead figure instead and ignore the annual headline.
Then this is not your problem and no tool on this page will fix it. Look at your quote turnaround, your pricing against the local market, and how many follow-up attempts a quote gets before you give up. Speed only gets you into the conversation. It does not win it.
It is written out in the "How this is calculated" section above, including the ceiling that stops the instant-response scenario from implying an absurd close rate. Nothing is hidden and you can reproduce every figure on paper.
