How do I add the calculator to my website?

Paste one where you want the calculator, then include once. The widget loads and auto-resizes itself. Works on WordPress, Webflow, plain HTML and most CMSs.

Which niches are available?

Thirteen: general website, restaurant, nonprofit, law firm, e-commerce, real estate, freelance, SaaS / web app, landing page, contractor, WordPress, Shopify and Magento. Each widget is pre-tuned with realistic presets for that niche.

Can I use the calculator with my own branding and my own call-to-action?

Yes, with an Embed Pro licence — a one-time $290 payment for one domain and its subdomains. Pro points the button after the estimate at your own quote or contact page, shows your brand name, applies your accent colour, and removes the Powered by Project Cost Estimator credit from inside the widget. The free widget stays free and unchanged.

Free Website Cost Calculator Widget

Q: Is the website cost calculator widget free to embed?

Yes. The widget is completely free to embed on any website with no signup and no API key. It runs the same 9-engine calculator behind projectcostestimator.com and shows real budget, realistic and premium ranges.

Give your readers an instant, honest website cost estimate — embedded right on your page. One line of code, no signup, no API key. It runs the same 9-engine calculator behind this site.

How it works

Paste the <div> where you want the calculator.
Add the <script> once, anywhere on the page.
It loads and resizes itself. Works on WordPress, Webflow, and plain HTML.

Free forever. The free widget keeps a small “Project Cost Estimator” credit link below it — that is how it stays free, and it is added automatically even if you paste only the two code lines. An Embed Pro licence removes it. No tracking cookies are set on your visitors.

Embed Pro — make it your calculator

The free widget above is honest about who it works for: it sends your visitor to our calculator and carries our credit line. Embed Pro turns the same engine into your own lead magnet — the visitor prices their project on your page, then goes to your contact form.

Your call-to-action — The button after the estimate points at your quote or contact page, not ours.
Your brand — Your name in the footer line. Our "Powered by Project Cost Estimator" credit is removed.
Your colour — One hex value restyles the whole widget to match your site.
All 13 niches — Restaurant, law firm, e-commerce, SaaS, real estate, WordPress, Shopify, Magento and more — one licence covers every one.
The pricing model is already built — It runs the same 9-engine calculator behind this site, calibrated on 600+ project quotes and public rate benchmarks across 6 markets.

Installation is the same one line of code. Nothing to host, nothing to maintain — the widget is served from our origin and updates itself. Your visitors' answers stay in their browser; the widget sets no tracking cookies on them.

Embed Pro licence

$290

one-time · one domain · no subscription

Which domain will it run on?

Paid by PayPal. Your licence key and ready-to-paste snippet appear on screen the moment the payment clears — nothing to wait for.

What exactly am I buying?

A licence key that unlocks the branded rendering of the widget on one domain (including its subdomains). The key is a signed string you paste into the embed snippet. There is no account to create and no dashboard to log into.

Do I still need the free version?

No. The free widget stays free and unchanged for anyone who wants it — Pro is the same calculator with the branding and the destination handed over to you.

Can I use it on client sites?

One licence covers one domain. If you build sites for clients, buy one licence per client domain — each gets its own key, brand name and colour.

If I lose the key?

The key is derived from your domain and the email on your PayPal payment, so it can be re-issued identically. Email hello@projectcostestimator.com from that address.
