Put free cost calculators on your website
21 state-adjusted home improvement calculators. One line of code. Zero maintenance. Free forever.
Who uses PermitDeck embeds
Anyone with a homeowner, contractor, or real estate audience who wants an interactive cost tool without building one.
Real estate agents & brokerages
Add a cost estimator to your listing pages so buyers can ballpark renovation budgets before they write the offer. Works on IDX sites, single-property landing pages, and agent blogs.
Home improvement bloggers
Drop a calculator inside any cost-focused post. Readers get an interactive tool without leaving your page, time-on-page goes up, and you never have to maintain contractor pricing data.
Contractors & service businesses
Put a calculator on your service pages as a lead magnet. Visitors who engage with a cost estimator convert to consultation requests at 3-5x the rate of static pages.
Mortgage, refi, HELOC, and finance sites
Help borrowers estimate project budgets when they're researching home improvement financing. Embeds pair naturally with renovation loan and HELOC content.
Why publishers embed our calculators
One line of code
Copy-paste an iframe snippet. No API keys, no signup, no billing, no JavaScript framework required.
Zero maintenance
We update pricing data weekly from contractor bid databases. Your embedded calculator always shows current numbers.
State-adjusted estimates
Readers select their state and get a cost range calibrated to local labor, materials, and permit fees.
Responsive out of the box
Works on mobile, tablet, desktop. Auto-resize snippet eliminates internal scrollbars on publisher pages.
Keeps readers on your page
The calculator renders inline, not in a popup. Readers engage with the tool without bouncing off your site.
No tracking, no cookies
Embed pages don't set cookies on your visitors or send data anywhere beyond what your own site already does.

Frequently asked questions
Is it really free?+
Yes. No payment, no signup, no API key, no rate limits. We build PermitDeck as a free resource for homeowners and publishers alike. The only thing we ask is that you keep the "by PermitDeck" attribution link in the embed code.
Can I remove the attribution link?+
Please leave it in. The attribution is how we sustainably offer the calculators for free — each embed drives a small amount of traffic back to PermitDeck, which lets us keep the pricing data up to date. It's one small text link at the bottom of the calculator.
Will the calculator slow my page down?+
No. The calculator loads in an iframe, which means it renders independently of your main page content. Your own page loads at full speed and the calculator streams in afterward. We use Vercel edge hosting so the iframe itself loads in under 500ms globally.
Does it work on WordPress?+
Yes. Use the "Custom HTML" block (Gutenberg) or the "Text" tab in the Classic editor and paste the embed code. No plugin required. It works on WordPress.com (Business plan or higher) and any self-hosted WordPress site.
Does it work on Squarespace, Webflow, or Ghost?+
Yes. Squarespace: use a Code Block. Webflow: use an Embed element. Ghost: use an HTML card. All three support iframe embeds with no extra configuration.
Can I customize the styling?+
The iframe itself accepts standard HTML attributes (width, height, border, max-width). The calculator inside renders in our default theme, which is designed to look clean on any background. If you need a custom color scheme or a white-label version, email support@permitdeck.com.
What happens if your site goes down?+
If permitdeck.com is unavailable, the iframe will show a blank area until we recover. We run on Vercel with 99.99% uptime, so this is very rare. For mission-critical use cases, you can cache the embed URL via a service like Cloudflare.
Are the pricing estimates accurate?+
We source pricing from contractor bid databases (HomeAdvisor, Angi, regional surveys) and adjust by state for labor and materials. Estimates are presented as ranges — low, typical, high — and should be treated as starting points, not firm quotes. We always recommend readers get 3 written bids from local licensed contractors before committing.
Can I see the underlying data?+
Each calculator page has a "How we calculate" section explaining the methodology. The per-state adjustments use a cost-of-living multiplier applied to a national median. For deeper data access or licensing, email support@permitdeck.com.
Can I track embed analytics?+
Right now, no per-publisher dashboard — we don't want to ask you to create an account. If there's enough interest we may add an optional tracking parameter. For now, use your own site analytics to measure engagement with the iframe.
