Pricing formula from your rates
Base rates, material lines, pitch or access charges, and minimums, written down and checked with you.
The Problem
Tire-Kickers Fill Your Estimate Calendar
Homeowners want a number first. When your site can't give one, they call around, and you drive out to measure jobs that were outside their budget from the start.
01 · Wasted mornings
You spend Saturday on a ladder for someone who wanted a number.
Homeowners see a price range from your own rates before you drive out.
02 · Blank requests
Monday brings requests asking what a deck costs, with no details.
Each lead lands in your inbox or job software with its answers attached.
03 · Browsers
Free estimates for browsers eat time meant for real buyers.
Answers about budget and timing show which leads are worth a visit.
04 · Out-of-area
Requests come from towns outside your service area.
The calculator checks each ZIP code against your service area.
It's Saturday morning, and you're measuring a roof for a homeowner who found you online. You spend the morning on the ladder and the evening on the estimate. They only wanted a number for next year's budget. Monday brings more requests with no details, just a message asking how much a deck costs. Your crews need you on jobs, not in the truck. Every free estimate for a browser is time you could have spent closing a real buyer.
We start with how you actually price a job: base rates, material lines, pitch or access charges, and your minimum. The calculator asks those questions in plain words, checks the ZIP code against your service area, and shows a range once the homeowner leaves contact details. Budget and timeline answers sort buyers from browsers. You drive out to people who already know the ballpark, not to strangers testing prices.
Ranges from your own rates
Each result uses your prices, material lines, and minimums, shown as a range until you inspect.
Screened before you drive
ZIP, budget, and timeline answers flag which leads deserve a visit.
Details travel with the lead
Leads reach your inbox or job software with every input attached.
Our Contractor Calculator Build Process
From Your Price Sheet to a Live Estimator in Five Steps
You approve the math, the questions, and the lead routing before homeowners see a number. We test every formula against jobs you've already quoted.
We go through how you price your main job types: rates, material lines, pitch or access charges, and minimums. You share a handful of past quotes, and we show where a range works better than an exact number.
What's Included
What You Get With a Contractor Estimate Calculator Widget
Every plan prices your job types from your own rates and screens each lead before the range. Larger plans add Jobber, Housecall Pro, or ServiceTitan delivery, photo uploads, map tracing, and funnel reports.

What Our Clients Say
What Clients Say After Launch
Feedback from teams we have built calculators and service business websites for.
We had a pretty specific idea of what we wanted our website to become, but I wasn’t sure how easily we could explain all of it to a development team. There were quite a few moving parts, and we were working toward a deadline, so I expected a few things to get lost along the way. That never really happened. They understood what we were trying to achieve, kept us updated throughout the process, and got everything ready within the agreed timeline. The final site feels much easier to navigate, works beautifully on mobile, and is noticeably smoother for our customers. It was a huge relief seeing the original idea actually turn into the website we had in mind.
The mobile experience is probably my favourite part of the new site. We had spent a lot of time making sure the desktop version looked right, and the team kept pushing us to think about how everything would actually feel on a phone too. They were right. The navigation is clean, the interactions feel natural, and everything we’ve tested so far works exactly as it should. They also went through the links, forms, integrations, and other details more than once before launch, which I really appreciated. And even after going live, we could still reach out when something came up. The whole process felt friendly, organised, and surprisingly straightforward.
What I appreciate most is that the website is actually easy for us to manage now. We can update content ourselves instead of sending a developer a message every time we need to change something small. They also paid attention to the technical SEO side, which mattered to us because we didn’t want a new website to create problems for the traffic we already had. I’ve probably asked more questions than I should have since launch, but every question has been handled patiently and without any fuss. The team is easy to work with, they explain things clearly, and when we need something changed, they focus on getting it done rather than making the process complicated.

Work Culture
Why Trades Trust Us With Their Price Math
A calculator speaks for you while you're on a roof. These habits keep its numbers honest, its questions short, and its leads worth the drive.
Ranges, not promises
The calculator shows a range until you've seen the job, and it says why. Homeowners get a real ballpark without a number you can't honor.
Checked against finished jobs
Before launch, jobs from your own records go through the formula next to what you charged. Any gap gets fixed before a homeowner sees a number.
Screening that stays polite
Budget and timeline questions let people skip, so serious buyers aren't scared off. You still see who is ready now and who is only browsing.
Every input travels with the lead
Measurements, choices, photos, and the range shown all arrive with the lead. Your callback starts with the details instead of the same questions again.
Honest about fit
If a starting-at price on your service page would do the job, we'll say so before we quote. A calculator earns its cost only when prices really vary.
You own the math
You own the calculator code, the formula document, and every lead it collects. Price changes don't depend on us or our schedule.
Overview
How does an online contractor quote calculator work?
DeveloperLook builds the contractor quote calculator that answers a homeowner's price question and hands you a screened lead. Each build turns your rates into short steps: measurements, material choices, a service-area check, and a contact step before the range. Builds start at $850, take 1 to 8 weeks, and you own the code and the formula.

Good fit
Roofers who price by the square
You quote replacements by squares, pitch, and shingle line. Homeowners want a ballpark before they let anyone on the roof.
Remodelers tired of budget surprises
You want a construction cost estimator website visitors can use to test a kitchen or addition budget before they book a consultation.
Fence, gutter, and siding companies
You price by the linear foot or square foot, and the same price questions eat your mornings on the phone.
Crews on Jobber, Housecall Pro, or ServiceTitan
Your web leads arrive as bare emails, and your office retypes each one into your field software before anyone calls back.
Agencies with trade clients
Your agency runs ads for contractors and wants a calculator on the WordPress, Webflow, or Wix landing page that turns clicks into screened requests.
Not a fit
Full signed estimates
You need a full estimate with line items and a signed contract, not a ballpark. Contractor Proposal & Estimating Software Integration covers that step.
Store products, not jobs
You sell store products by coverage or quantity, not trade jobs. Our Quote Calculator Development page is the general version for stores and other service businesses.
Landscaping materials and plans
You run a landscaping company pricing sod, mulch, and maintenance visits. Landscaping Cost Calculator Development covers those materials and recurring plans.
Every job needs a visit
Your budget is under $850, or every job needs a site visit anyway. A clear starting-at price on your service pages is cheaper and works fine.

A contractor calculator starts at $850 for 1 job type with up to 10 inputs, a contact step, a ZIP check, and email alerts. Plans with 3 job types, photo upload, lead scores, and delivery into your job software cost $1,950. Multi-trade engines with map tracing start at $3,950, fixed after a free pricing review.
A single job type goes live in 1 to 2 weeks once you approve the formula. Setups with 3 job types and software delivery take 3 to 4 weeks, and multi-trade engines with map tracing take 6 to 8. Agreeing on minimums and range width often takes longer than the code itself.
Yes, by asking what your estimator would ask before driving out. A ZIP check turns away out-of-area requests, your minimum job size shows up front, and budget, timeline, and owner or renter answers score each lead. Browsers still get a range, but they land on a separate list, not your estimate calendar.
You place a short contact step between the last question and the range. Homeowners see that their price is ready, enter a name, phone, and email, and then see the range. We keep that step to 3 fields, and the lead is saved even if they close the tab afterward.
A range suits most trade jobs, because the final price depends on things only an inspection reveals. Roof decking, rot, and access all move the number. Fixed-scope work, like gutter cleaning by the linear foot, can show an exact price, and one calculator can mix both by job type.
It answers the question most visitors arrived with, so fewer leave to call around. Each question is a small step, and people who've entered their measurements have a reason to finish. We track starts, completions, and contact steps in GA4, so you see your own conversion rate before and after launch.
Yes, every answer recalculates the range on the spot. Square footage multiplies by the material rate, then waste, pitch or access factors, and your minimum apply. From the Qualified Lead Estimator plan up, rates live in a Google Sheet your office edits, so a shingle price change is one edit.
For a roofing calculator, website visitors trace the roof outline on a satellite map instead of climbing a ladder. Google's Maps geometry library returns the footprint area, and the homeowner picks a pitch from pictures. A 6/12 pitch adds about 12% of surface over the footprint, then squares, waste, and your rates set the range. Map tracing comes with our Multi-Trade Estimate Engine plan.
Yes, an instant quote calculator for contractors can send each lead straight into your field software. Jobber takes requests through Zapier or its GraphQL API, and ServiceTitan takes bookings through an approved customer-built app, not shared keys. Housecall Pro accepts API leads on its MAX plan, in the Job Inbox.
You do: the code, the formula document, the price sheet, and every lead belong to you from launch day. The calculator runs on your site or hosting, with no per-lead fees from us. Support covers 30, 60, or 90 days depending on plan, and formula updates after that are billed as small fixed jobs.
