Speed to lead calculator
Slow follow-up costs jobs because intent fades and competitors answer first. Estimate it as (contact rate at 5 minutes − contact rate now) × leads × close rate × job value. On 120 leads at $9,500, moving from a one-hour reply to five minutes is worth roughly 6 jobs a month — an estimate, driven by the assumptions below.
What the wait is costing
Every form fill and inbound enquiry, before qualification.
Enquiry arriving to a human speaking to them. Count overnight and weekend waits.
Of the people you actually speak to, how many end up signing.
Assumptions — change these to match your own experience
The share of leads you would actually reach if you answered immediately.
Percentage points of contact rate given up each time response time multiplies by ten.
Modelled from your assumptions, not measured. Treat it as an order of magnitude.
Against answering every lead inside five minutes.
Same leads, same close rate — only the response time changes.
Down from 80.0% at a five-minute reply.
About 77 leads reached, 23 jobs signed.
About 96 leads reached, 29 jobs signed.
How to use this calculator
Enter your lead volume, your genuine average response time, your average job value and the rate at which you close the people you actually get hold of. Then read the two assumption boxes underneath and change them if they do not match what you see in your own business.
Those two assumptions do all the work, so they are inputs rather than constants baked into the page. The first is the contact rate you would hit answering within five minutes. The second is how steeply contact rate falls as the wait grows, expressed as percentage points lost each time response time multiplies by ten — five minutes to fifty, fifty to five hundred.
This is an estimate and it is labelled as one throughout. Contact rates and their decay vary by trade, market, time of day and how the enquiry arrived, and nobody has a universal figure for your business. The output is here to show whether response time deserves attention, not to forecast a bank balance.
A worked example
A pressure washing company gets 120 leads a month, averages $9,500 a job, and closes 30% of the people it speaks to. Enquiries are worked from an inbox, so average response time is about 60 minutes.
They believe they would reach 80% of leads answering inside five minutes, and lose about 15 points of contact rate each time the wait multiplies by ten. Sixty minutes is twelve times five minutes, so the model puts their current contact rate at roughly 64%.
That is about 77 leads reached instead of 96, or 23 jobs instead of 29. Six jobs a month at $9,500 is roughly $55,000 of monthly revenue and around $664,000 a year — from a delay that exists because nobody is watching the inbox.
Reading the result honestly
- The annual figure looks implausible. It usually does, because it multiplies a per-lead effect across a year. Check the monthly job count instead: if the model says you are losing six jobs a month and that feels wrong, lower the decay assumption until it feels right.
- Your response time is already under five minutes. The model shows no loss, which is correct on its own terms. The remaining lever is coverage — evenings, weekends and lunch breaks — not raw speed.
- The average hides the problem. A two-minute weekday average with nothing answered on a Saturday is not a two-minute business. Recalculate with the true average including overnight waits and the number changes sharply.
- Contact rate is already low at five minutes. If you would only reach half of leads even answering instantly, the problem is lead quality or bad contact details, and speed will not fix it.
The common mistake
Measuring response time from when someone looked at the lead rather than from when it arrived. A form submitted at 6:40pm and called at 8:15am is a fourteen-hour response, and averaging it in is what makes the real number three or four times worse than the one people quote. Take the timestamps from the CRM for a full month, including nights and weekends, and use that figure here.
The second mistake is treating an automated text as the response. It is a holding action — useful, and much better than silence — but the clock that matters runs until a human is talking to the homeowner.
Faster follow-up also raises what you can afford to pay for a lead in the first place: check the new ceiling with the max cost per lead calculator. The appointments you save still have to happen, which is what the no-show cost calculator covers, and the cost per booked job calculator shows the whole funnel in one view. There is more on the mechanics in speed to lead for contractors.
Common questions
What is speed to lead?
Speed to lead is the elapsed time between an enquiry arriving and a human being making contact with the person who sent it. It is measured from the timestamp on the form fill or missed call, not from when the office opened. The distinction matters because a lead that comes in at 7pm and is called at 9am the next day has a response time of fourteen hours, not fifteen minutes.
Why does response time affect how many jobs get booked?
Two things happen while a lead waits. Intent decays, because the homeowner moves on to something else and the urgency that made them enquire fades. And competition arrives, because most homeowners contact more than one contractor and the first to answer gets the conversation. Neither effect requires the lead to have been bad — the same enquiry converts differently depending on who reaches it first.
How is the estimate on this page calculated?
It is a model, not a measurement. You supply the contact rate you believe you would hit answering within five minutes, and how many percentage points of contact rate you lose each time response time multiplies by ten. The calculator applies that decay to your actual response time and compares the resulting revenue against the five-minute case. Both assumptions are editable because both vary by market and trade.
Are the numbers this produces reliable?
They are only as reliable as the two assumptions behind them, which is why those assumptions are inputs rather than hidden constants. Treat the output as an order-of-magnitude estimate that shows whether response time is worth attention, not as a forecast. The way to make it real is to measure your own contact rate at different response times for a month and enter those figures instead.
What is a realistic target for response time?
Under five minutes during business hours is the standard most well-run contractor offices aim at, and under one minute is achievable with automation. The bigger win is usually coverage rather than speed: an office that answers in two minutes on weekdays and never on Saturday has a much worse effective response time than the weekday average suggests.
Does an automated text count as responding to a lead?
It counts as holding the lead, not as working it. An instant text that acknowledges the enquiry and asks a question keeps the homeowner engaged and stops them dialling the next contractor, which is genuinely valuable. It does not replace a human conversation, and an automated reply followed by four hours of silence performs close to no reply at all.
Is it better to respond faster or to buy more leads?
Responding faster is almost always the cheaper move, because it costs a process change rather than a budget increase and it improves the return on every lead already being bought. Buying more leads while response time stays slow multiplies the same loss. Fix the response first, then scale the volume against a funnel that can hold it.
How do you actually improve speed to lead?
Route every enquiry to a phone rather than an inbox, trigger an instant automated text on form submission, put a named person on call outside office hours, and measure the time to first human contact rather than time to first touch. Most of the improvement comes from removing the wait for someone to check email, which is where the majority of the delay usually sits.
