Is the DwellQ rent vs buy widget free to embed?

Yes. There is no key, no account and no fee, for commercial or non-commercial sites. The one condition is that the "Powered by DwellQ" line stays visible.

Does the widget track my readers?

The calculation runs in the reader’s own browser and the numbers they type are never sent to DwellQ. The embedded page records a single pageview, the same as any page on dwellq.io, and nothing else.

What size should the iframe be?

Width 100% and height 420 pixels covers most layouts. The widget is fluid and stays readable down to about 300 pixels wide, so it fits a narrow sidebar as well as a full-width article.

EMBED

Put the rent-vs-buy answer on your own page.

The DwellQ widget is a compact version of our rent-vs-buy calculator, sized to drop into an article, a listing page, or a sidebar. A reader types four numbers — home price, down payment, monthly rent, and how long they plan to stay — and gets the same verdict our full calculator gives: which path is ahead at their horizon, by how much, and the year the two paths cross.

The snippet

Paste this wherever you want it. No script tag, no API key, no account.

<iframe src="https://www.dwellq.io/embed/rent-vs-buy" width="100%" height="420" style="border:0;border-radius:12px" title="Rent vs Buy Calculator by DwellQ" loading="lazy"></iframe>

The widget is fluid: it fills whatever width you give it and stays readable down to about 300 pixels, so it works in a narrow sidebar as well as a full-width article. The 420 pixels of height is measured rather than guessed — the widget stands 415 pixels tall at its narrowest and gets shorter as the column widens, so nothing is cut off and nothing scrolls inside the frame.

What it does, and does not, do

The math runs entirely in your reader’s browser. The widget loads our engine — the same one behind the full calculator — and computes the verdict locally. The numbers a reader types are never sent to us. The one thing it fetches is today’s 30-year mortgage rate, and if that request fails it says so and falls back to a typical rate rather than showing a blank.

It is not a full analysis. The widget holds four inputs and uses standard assumptions for everything else — appreciation, rent growth, investment return, taxes, insurance, maintenance. It labels those as typical values rather than pretending they are your reader’s. The link at the bottom of the widget carries the four numbers through to the full calculator, where all of it is editable and every source is named.

Attribution

The widget is free to embed on any site, commercial or not, and there is nothing to sign. What we ask in return is the line already built into it: “Powered by DwellQ — run the full analysis”, linking back here. That footer is how the widget pays for itself, so please leave it visible rather than cropping or overlaying it. Beyond that, embed it wherever it is useful — we would rather more people met honest rent-vs-buy math than own the page it happens on.
