Almost everyone in home services watches the cost of capturing a lead and almost no one watches the cost of answering it late. And yet that is where most of the money spent on marketing evaporates: the ad works, the form comes in, the phone rings, but twenty, forty, sixty minutes pass between that moment and the first useful reply. By then the customer has already spoken to another company.
This calculator puts a number on that delay. Adjust your figures above and watch, in real time, how many jobs you fail to book by responding late and how much extra revenue you would recover by responding in five minutes.
How to read the results
- Extra revenue per year is the headline figure: what you would earn over twelve months if you responded in five minutes instead of your current time.
- Effective close rate now is your real close rate once the penalty for slow response is applied. The longer you take, the further it drifts from your potential close rate.
- Extra jobs/month translates the difference into something tangible: how many more jobs you would book each month just by responding sooner.
- Extra revenue/month is that difference in dollars, before it is projected across the year.
Response speed is not an opinion
The effect of responding fast has been measured. Harvard Business Review research across thousands of leads found that contacting a prospect within the first five minutes makes you 100 times more likely to reach them and 21 times more likely to qualify them than waiting thirty minutes. This is not a nuance: it is an order of magnitude. For home emergencies, where the customer is calling two or three companies at once, the window is narrower still.
The decay model is directional
The calculator does not try to reproduce your business to the decimal. It uses a decay curve,
decay(m) = 1 / (1 + max(0, m-5)/20), that takes five minutes as the no-loss baseline and
reduces conversion as response time grows: at five minutes or less it equals 1, near
twenty-five minutes it halves, and it keeps falling after that. It is an honest approximation of
the pattern the research measures, built to give you an order of magnitude, not a promise. Your
real numbers depend on your volume, your ticket and your market.
How to hit five minutes
Responding in five minutes does not mean living on the phone. It means closing the gap between a lead arriving and first useful contact, and that almost always means automating:
- An AI receptionist that answers 100% of calls instantly, even at night or with several at once, and captures name, address and job type.
- An immediate reply to form and text leads, with an alert to the technician for human follow-up.
- A clear process for who responds, in how long, and with what message, so no lead is left waiting.
What to do with the number
If the annual figure surprised you, the next step is to understand why you respond late: hours, simultaneity, the lack of a process. The conversion page and the 5-minute rule guide explain how to close that leak. If you suspect part of the problem is calls you never even pick up, pair this tool with the missed-call revenue calculator.
