How to Calculate Your Estimate Close Rate (and What It's Really Telling You)
Ask a service business owner how many jobs they sold last month, and you'll usually get an answer.
Ask how many estimates they gave to win those jobs, and things get a little less clear.
You'll hear things like, "We close most of them," or "We've been pretty busy."
That's fine, but it doesn't tell you much.
If you're spending money to generate leads, paying someone to answer the phone, preparing estimates, and following up with customers, you should know how many of those opportunities are actually turning into jobs.
And there's another part to this that I think is just as important.
A high close rate isn't necessarily a good thing if you're winning jobs that aren't profitable.
So let's look at how to calculate your close rate, what the number can tell you, and how to use it to make better decisions.
What Is an Estimate Close Rate?
Your estimate close rate, sometimes called a quote conversion rate, is the percentage of estimates that turn into sold jobs.
The basic formula is:
Estimate Close Rate = (Jobs Won ÷ Estimates Given) × 100
If you give 50 estimates and 25 become booked jobs, your close rate is 50%.
Simple enough.
But the calculation is only useful if you're clear about what you're counting.
For example, I would count a quote when a customer has actually received a price they can act on. That could be a detailed written proposal or a firm price given over the phone.
I wouldn't count a general conversation about what something might cost.
And I wouldn't consider a job sold just because someone says, "Sounds good, I'll call you back."
A confirmed booking, signed approval, or deposit is a much more meaningful definition of a sale.
Whatever definitions you use, apply them consistently.
Otherwise, you can end up comparing numbers that don't mean the same thing.
Let's Look at a Realistic Example
Imagine you own a window tint, detailing, window cleaning, or other service business.
Over a particular period, you receive 100 legitimate inquiries for services you offer.
Here's what happens:
100 qualified customer inquiries
60 estimates delivered
30 jobs booked
20 estimates declined or lost
10 estimates still undecided
Your estimate close rate so far is:
30 ÷ 60 = 50%
But there's more going on here.
Only 60 of your 100 inquiries received an estimate.
That means your inquiry-to-estimate rate was 60%.
And only 30 of the original 100 inquiries became booked jobs.
That's a 30% inquiry-to-booking rate.
Those numbers tell you different things.
If you only pay attention to the 50% estimate close rate, you could miss the fact that 40 potential customers never received a quote.
Maybe some weren't ready to buy. Maybe they stopped responding. Maybe the service wasn't a good fit. Or maybe somebody simply didn't get back to them.
You won't know until you look.
What About the 10 Estimates Still Open?
This is another detail worth getting right.
Of the 60 estimates, 30 were won, 20 were lost, and 10 haven't been decided.
If you divide the 30 wins by only the 50 estimates that have reached a decision, you get a 60% win rate.
That's a legitimate measurement, but it's different from the 50% of all estimates issued that have booked so far.
Neither number tells the entire story by itself.
Those 10 open estimates could all become jobs next week. Or they might sit untouched until everyone forgets about them.
For a fair comparison, look at estimates issued during the same period and give them a consistent amount of time to convert. A smaller automotive job may be decided quickly, while a commercial project might take months.
Don't treat open estimates as lost immediately. But don't leave them open forever just to keep your numbers looking good.
Why I Wouldn't Automatically Want a 90% Close Rate
This may sound strange, but if someone tells me they're closing almost every estimate they give, one of my first questions is whether they're charging enough.
Maybe they have an excellent reputation.
Maybe they're generating great leads and doing an outstanding job of selling.
Or maybe they're simply too cheap.
Here's an example of why close rate alone can be misleading.
Imagine two pricing approaches for the same service, each with 100 estimates.
Option A
Average selling price: $500
Direct variable cost per completed job: $300
Close rate: 70%
Jobs sold: 70
Contribution toward overhead and profit: $14,000
Option B
Average selling price: $575
Same $300 direct variable cost
Close rate: 55%
Jobs sold: 55
Contribution toward overhead and profit: $15,125
These are hypothetical numbers, but look at what happened.
In Option B, the company sold 15 fewer jobs.
Its close rate dropped from 70% to 55%.
It even generated less total revenue.
But it had $1,125 more left over to cover fixed overhead and profit, assuming its other costs and capacity didn't change.
That's why I wouldn't make increasing your close rate the goal by itself.
I would want to know whether you're winning the right jobs, at the right prices, with enough money left over to make those jobs worth doing.
A business can improve its close rate by discounting everything.
That doesn't necessarily make it a better business.
Not All Estimates Should Be Measured Together
I think this is one of the most useful changes a business owner can make.
Stop treating every estimate like it's the same kind of opportunity.
For example, a repeat residential window film customer who has used you before is very different from someone clicking on an advertisement and requesting quotes from five companies.
The same goes for a customer asking about tinting a sedan versus a commercial property manager considering a $30,000 project.
They have different needs, different buying processes, and different timelines.
At a minimum, I'd separate estimates by two things.
1. Where the customer came from
Look at referrals, Google organic search, paid advertising, repeat customers, and any other major sources.
Which ones actually turn into jobs?
A channel producing 100 inquiries with 15 booked jobs may not be as valuable as one producing 30 inquiries with 20 booked jobs.
Of course, you'd also want to compare acquisition cost, job value, and profitability.
This is something I discuss in more detail in How to Stop Guessing and Find Your Best Lead Sources.
2. What service they requested
Separate your major services.
For a window tint business, that could mean automotive tint, PPF, residential film, and commercial film.
For a cleaning business, it could mean one-time cleaning, recurring service, and larger projects.
You may discover that one service has a very high close rate but doesn't earn enough money to justify the time it consumes.
Another might close less frequently but produce considerably more contribution per job.
That's valuable information when deciding which services to promote, how to price them, and where to put your attention.
The Part of Your Sales Process You Might Be Missing
When we built Window Tint LA, one of the changes that made a real difference was getting estimates into customers' hands while we were still speaking with them.
Instead of measuring a job, leaving, and promising to send something later, we worked toward a process where the quote could be completed right there.
I've written about that in Why "I'll Send It Later" Is Costing You Sales.
But measuring your close rate adds another layer.
Now you can start asking better questions.
How many customers contacted you but never received a quote?
How long does it take your team to send an estimate?
How many people accept immediately?
How many accept after a follow-up?
How many never respond?
How many decline specifically because of price?
How many jobs are you winning after discounting?
You don't need twenty dashboards to answer those questions.
You need a process that records what happened.
How to Track Your Close Rate Without Complicating Everything
If you already use a CRM, much of this information may be available.
If not, a spreadsheet is enough to get started.
I'd record:
Customer and date: Who contacted you and when?
Lead source: How did they find you?
Service requested: What kind of work were they looking for?
Estimate amount and date: What did you quote, and when did they receive it?
Status: Won, lost, or still open.
Outcome date: When was the job accepted or declined?
Reason lost: Price, timing, competitor, no response, or whatever you can actually verify.
I'd also track the estimated contribution from jobs won if you have reliable job-cost information.
Don't fill in a reason just because you think you know why somebody didn't buy.
If you never spoke with them again, the accurate answer may simply be "No response."
Once you have this information, review it regularly.
Compare similar types of work over a reasonable period, and pay attention to small sample sizes. Closing seven out of ten estimates one month and six out of ten the next doesn't necessarily mean something meaningful changed.
Look for patterns before making big decisions.
Three Things I'd Check First
If your numbers aren't where you want them, I wouldn't immediately start changing your prices or buying more advertising.
I'd look at three things.
1. Are you quoting enough of the right inquiries?
If qualified people are contacting you but never receiving an estimate, figure out why.
Maybe you're responding too slowly.
Maybe the quote takes too long to prepare.
Maybe nobody is responsible for the next step.
Fixing that may be more valuable than generating another 50 leads.
2. Are you losing jobs you should reasonably be winning?
Look at customers who wanted the service, had the budget, were within your service area, and received a clear estimate.
Did they understand the options?
Did you answer their questions?
Did someone follow up?
Were you easy to work with?
I wouldn't assume every lost job is a pricing problem.
3. Are the jobs you're winning actually worth winning?
This is the one I would spend the most time on.
If your close rate improves because you're lowering prices, you may be moving backward.
If it improves because you're attracting better-qualified customers, presenting your service more clearly, and making the buying process easier, that's a different story.
The close rate tells you what happened.
Your margins, lead sources, and sales process help explain whether it was good for the business.
What Is a Good Estimate Close Rate?
There's no single percentage I'd recommend for every service business.
A window cleaner quoting repeat customers shouldn't expect the same rate as a commercial window film company pursuing large, competitive projects.
The better starting point is your own history.
Establish a reliable baseline.
Separate different services and customer sources.
Make one meaningful improvement, then see what changes.
And always keep an eye on what you're earning from the work you win.
I'd take a business closing 45% of its estimates at healthy margins over one closing 80% at prices that barely make financial sense.
The goal isn't to win every job.
It's to build a business where the jobs you do win are worth the time, money, and effort it takes to deliver them.
And you can't know whether you're doing that if you're not measuring what happens between the first inquiry and the sale.
