What a lead
actually costs.
Every published benchmark for contractor marketing, in one place — and an honest account of why they contradict each other, and what to use instead.
Ask what a contractor lead costs and you will get a number. Ask three sources and you will get three numbers that do not overlap. For roofing, figures published in 2026 run from roughly $70 to roughly $230 per lead — a 3x spread on the same trade in the same year.
Both ends are probably correct for whoever measured them. They are measuring different things: one counts every form fill, another counts leads that answered the phone, a third counts booked appointments, and almost none of them say which. Blend a dense metro with a rural county and the average describes nobody.
So this page does two things. It shows the reported ranges, honestly labelled as somebody else’s aggregates. Then it shows you the arithmetic that replaces them, because the number that decides whether your campaigns work is not on this page — it comes out of your job value, your margin and your close rate.
Cost per lead,
by where it came from.
Reported ranges across published 2026 benchmark roundups. Read down the intent, not the price: the cheapest column is the one where nobody was looking for you.
Cost per lead,
by what you sell.
Same caveat, larger spreads. Where a range is wide, the width is the finding — it means market and season move the number more than any targeting choice will.
Ranges are consolidated from marketing vendor and agency benchmark roundups published in 2026. They are self-reported and unaudited, methodologies are rarely stated, and they disagree with one another — treat every figure above as a sanity check on a quote, never as a target. Nothing on this page is JL Consulting client data; that lives on results, attributed.
Five minutes,
not five hours.
Most figures in contractor marketing are vendor aggregates. One is not. The 2007 Lead Response Management Study, run by Dr James B. Oldroyd (MIT Sloan) with InsideSales.com, analysed three years of data across six companies, more than 15,000 leads and over 100,000 call attempts, plus 495 survey responses gathered June–September 2007.
Contacting a lead at contacting at five minutes versus thirty minutes changed the odds of connecting by 100x and the odds of qualifying that lead by 21x. Nearly twenty years later it is still the most replicated finding in lead management, and most contractors still answer in hours.
It is also the most misattributed. You will see it credited to Harvard constantly. It is not a Harvard study — it is Oldroyd at MIT Sloan, and the original summary is public. A vendor citing “the Harvard study” for the 21x figure has not read it.
What that gap is worth in your business is arithmetic, not opinion — the speed to lead calculator puts a dollar figure on it using your own volume and close rate.
The number that actually decides it
Every figure above is an average of other people’s businesses. The only one that governs yours is the most you can pay for a lead and still make money, and it falls out of three things you already know: what a job is worth, what margin it carries, and what share of leads you close.
A $180 lead is cheap if you close one in four at $14,000 a job. A $40 lead is ruinous if it never answers the phone. This is why cost per lead is the wrong metric to manage and cost per booked job is the right one.
Work yours out before you buy anything:
- Max cost per lead — your ceiling, from job value, margin and conversion rates.
- Cost per booked job — what a booked sit-down really costs once show rate is in the maths.
- Break-even ROAS — the return that covers media before it covers anything else.
- Ad budget — the spend a revenue goal actually implies.
If you want the reasoning rather than the calculator, start with what a good cost per lead looks like, then how much to spend on ads. If a term on this page is unfamiliar, the glossary defines it in a sentence, and industries covers how the numbers move trade by trade.
Straight answers.
What is the average cost per lead for contractors?
Published 2026 roundups put most home-service trades somewhere between $25 and $230 per lead, depending far more on trade, channel and market density than on anything a contractor controls. That spread is too wide to plan against, which is the point: the useful number is not the industry average but the most you can pay and still profit, and that comes from your job value, gross margin and close rate.
Why do published cost-per-lead benchmarks disagree so much?
Because they measure different things and rarely say so. One roundup counts every form fill, another counts only leads that answered the phone, a third counts booked appointments. They also blend markets — a roofing lead in a dense metro and one in a rural county are not the same purchase. Roofing figures published in 2026 run from about $70 to about $230 per lead, and both ends are probably accurate for whoever measured them.
Is a cheaper lead always better?
No, and assuming so is the most expensive mistake in contractor marketing. A $40 lead that never answers the phone costs more than a $180 lead that books a sit-down, because the only cost that matters is cost per booked job. Channels that look expensive per lead — Google Search, Local Services Ads — often produce the cheapest booked jobs, because the person on the other end was actively looking for you.
How fast should a contractor respond to a new lead?
Within five minutes. The 2007 Lead Response Management Study — run by Dr James B. Oldroyd (MIT Sloan) with InsideSales.com across three years of data across six companies, more than 15,000 leads and over 100,000 call attempts, plus 495 survey responses gathered June–September 2007 — found that contacting at five minutes versus thirty minutes changed the odds of connecting by 100x and the odds of qualifying the lead by 21x. Nearly twenty years on, it remains the most-cited finding in lead management, and most contractors still respond in hours.
Is the five-minute rule from a Harvard study?
No, though it is constantly credited to one. The research behind the five-minute rule is the Lead Response Management Study, conducted by Dr James B. Oldroyd of MIT Sloan with InsideSales.com and published in 2007. Harvard Business Review later covered response-time research, which is where the misattribution comes from. If a vendor cites "the Harvard study" for the 21x figure, they have not read the source.
What should I do with these benchmarks?
Use them as a sanity check on a quote, not as a target. If someone offers you leads at a tenth of the published range for your trade, ask how many companies each lead is sold to. If a channel is quoted well above the range, ask what share become booked jobs. Then work out your own ceiling from job value, margin and close rate, and buy anything below it.
