He brought it up at a trade association dinner in Phoenix, and the table went quiet.
“We charge $350 for every detailed estimate we produce. We've been doing it for three years.”
He runs a high-end remodeling company — 11 employees, projects in the $80,000 to $300,000 range. His close rate on proposals had been 22 percent. His close rate on paid-estimate engagements is 71 percent.
The contractor across from him shook his head. “I'd never get another call.”
Both of them are right. Both of them are also answering the wrong question.
The Myth of the Free Estimate
There is no free estimate.
You have been offering “free estimates” for years, and what you have actually been doing is funding those estimates yourself — out of labor, out of margin, out of the evenings and Sundays when no one is tracking the clock.
The estimate is not free. You are paying for it. You are just not billing the cost to anyone, which means it disappears into your overhead and resurfaces as the reason your margins are tighter than your numbers say they should be.
The correct question is not: Should I charge the client for the estimate?
The correct question is: How much am I currently paying to produce each estimate — and who is absorbing that cost?
Right now, the answer is you.
What an Estimate Actually Costs to Produce
The math is not complicated, and most contractors have never run it.
An estimate has three cost components: time, labor rate, and win rate.
Time is how long it takes to produce a complete, accurate proposal — from site visit to delivered document. This is not a quick calculation. A detailed residential estimate for a $120,000 remodel runs 5 to 8 hours for most contractors: site visit, material takeoff, sub coordination, labor pricing, proposal writing, review. A commercial bid for an industrial HVAC system or a large landscaping contract runs 10 to 20 hours when specs, drawings, and sub quotes are involved.
Labor rate is what that time is worth. If the owner is the estimator — which is the case in most 5 to 15 person service businesses — the effective rate on that time is $75 to $150 per hour. Not the billable rate on a job. The value of the owner's time based on what the business produces when that time is applied to revenue-generating work instead.
Win rate is the multiplier that turns individual estimate cost into the real overhead per closed deal.
Here is what the math looks like at a 25 percent win rate — which is roughly average for competitive trade bidding:
To close 4 deals, you produce 16 estimates. You win 4 of them. You fund 12 losing estimates out of pocket.
On a 6-hour residential estimate at a $100 effective rate: each estimate costs $600. At a 25 percent win rate, the estimating cost embedded in every won job is $600 × 4 — $2,400 in estimating overhead per closed deal, before a single hour of production work begins.
On a 10-hour commercial bid at the same rate: $1,000 per estimate, $4,000 per won deal.
That overhead is real. It shows up somewhere — either in your margin, in your pricing, or in the unpaid hours you're putting in after 9 PM.
The “free estimate” is costing you $2,000 to $4,000 per closed job, depending on your win rate and the complexity of your bids. You are already paying for it. You're just not seeing the invoice.
The $150 to $1,000 Range — What It Actually Spans
The range in the headline is not arbitrary. It reflects the real cost distribution across different bid types.
$150 to $300 — Simple service quote. An HVAC maintenance contract, a commercial landscaping cleanup bid, a standard painting estimate on a single-family home. One to two hours of assessment and pricing. At a $100 effective rate, the cost to produce it is $100 to $200. At a 30 percent win rate, the embedded overhead per won job is $350 to $700.
$300 to $600 — Detailed residential project estimate. Custom remodel, outdoor living space, new construction phase bid. Four to six hours from walkthrough to proposal. Cost to produce: $400 to $600. At a 25 percent win rate: $1,600 to $2,400 per won deal.
$600 to $1,000+ — Complex commercial or multi-trade bid. Industrial systems, commercial construction phases, large facility contracts requiring sub coordination, drawing review, and spec compliance. Eight to twelve hours. Cost to produce: $800 to $1,200. At a 20 percent win rate on competitive commercial work: $4,000 to $6,000 per closed deal.
None of these are outrageous numbers to charge a client if your proposal has value. None of them are visible to you right now because they're buried in your overhead instead of appearing as a line item.
When Charging Works — and When It Doesn't
The Phoenix remodeler charges $350 because his clients are already committed when they call him. They found him through referral or his portfolio. They are not price shopping. When they pay $350 for an estimate, the barrier filters out the tire-kickers and signals mutual seriousness. His close rate tripled not because the $350 changed his proposal, but because it changed who he was producing proposals for.
This works in markets where the client has already established trust before the estimate request, the project scope is complex enough that the estimate itself has value as a planning document, the competitor set does not uniformly offer free estimates, and the contractor's reputation supports the ask.
It does not work in markets where the client is genuinely price shopping with no prior relationship, the competitor set universally offers free estimates and the client has no reason to choose differently, or the business is in an earlier stage where lead volume matters more than lead quality.
Neither of these situations is permanent. The contractor who charges for estimates today built to a position where that was possible. He did not start there.
The Question Underneath the Question
The debate about whether to charge for estimates misses the deeper problem.
The reason “free estimates” feel financially painful is not that you are giving something away. It is that producing an estimate takes too long and the inputs are too unreliable. A process that takes 6 hours to produce a $120,000 proposal will feel economically wrong whether you charge $0 or $350, because the underlying production cost is the constraint.
If a detailed takeoff took 90 minutes instead of 6 hours, the economics of free estimating would change entirely. The overhead per estimate drops from $600 to $150. The overhead per won deal at a 25 percent win rate drops from $2,400 to $600. The financial pressure to either charge for estimates or stop bidding competitive work disappears.
That is the lever that actually matters: the cost to produce the estimate, not whether to pass that cost to the client.
When takeoff — the part that consumes 50 to 80 percent of total estimate time — is faster, every downstream question gets easier. The math on free estimates works. The margin on won jobs improves. The pressure of funding 12 losing estimates to close 4 deals becomes bearable, because 12 estimates no longer means 72 hours of unpaid labor.
What to Do With This Calculation
Run the math on your own estimating overhead. Not a projection — the actual numbers.
How many proposals did you produce last month? How many hours did each one take? What is your win rate? What does that imply about your true cost per closed deal?
If the number is under $500, your estimating process is efficient and free estimates may be sustainable. If the number is above $1,000, you are funding a significant overhead item invisibly, and you have two choices: charge for it, or make it cheaper to produce.
Most contractors who run this calculation for the first time do not come out saying they want to charge for estimates. They come out saying they never want to spend 6 hours on a proposal again.
Both reactions lead to the same place: estimating has to cost less to produce.

Frequently Asked Questions
Should contractors charge for estimates?
It depends on the market, the client relationship, and the bid complexity. Contractors who have built strong referral pipelines and serve clients who have already expressed genuine intent can successfully charge $200 to $500 for detailed estimates — and typically see higher close rates because the fee filters for seriousness. Contractors in competitive markets with no prior client relationship face higher friction charging for estimates. In either case, the more important lever is the cost to produce each estimate. Contractors spending 6 to 8 hours on a $100,000 residential estimate are absorbing $600 to $800 in untracked overhead per proposal — which compounds across a 25 percent win rate into $2,400 to $3,200 in estimating cost per closed deal.
How much does it cost a contractor to produce an estimate?
Estimating cost depends on proposal complexity and the effective rate of the person producing it. A simple service quote (1–2 hours at $75–$100/hour effective rate) costs $75 to $200 to produce. A detailed residential estimate (4–6 hours) costs $400 to $600. A complex commercial bid (8–12 hours) costs $800 to $1,200. These costs are almost never tracked explicitly — they disappear into overhead, owner time, and after-hours work — but they are real and show up in tightened margins on won jobs.
What is the real overhead cost of free estimates?
At a 25 percent win rate, a contractor producing 16 estimates to close 4 deals is funding 12 losing estimates out of pocket. If each estimate costs $600 to produce, the estimating overhead embedded in every won job is $2,400 — before any production labor begins. At a 20 percent win rate, the same math produces $3,000 per closed deal in invisible estimating overhead. Most contractors know their material and labor margins. Almost none of them have calculated their estimating overhead.
How do contractors reduce the cost of estimating without charging clients?
The largest opportunity is in the takeoff phase — information extraction and scope quantification — which consumes 50 to 80 percent of total estimate time. Contractors who systematize site notes into estimate-ready formats, process scope documents or recorded walkthroughs into structured line items, and use template-based pricing structures can reduce estimate production time from 6–8 hours to under 2 hours on comparable jobs. At that level, the overhead per estimate drops to $150 to $200, and the economics of free estimating become sustainable even at a 25 percent win rate.
