Real estate calculators are some of the most useful interactive tools you can offer your visitors. Whether you run a real estate blog, a property management company website, or an investor community, calculators keep people on your site longer, provide genuine value, and position you as a trusted resource.
These embeds are completely free — no account required, no usage limits, no hidden fees. Each embed includes a small "by PropMetrics" credit link. Please keep the attribution in place — it's how we keep these tools free. You get a professional calculator for your visitors, we get a link back. Fair trade.
Copy the embed code and paste it into your HTML, CMS, or site builder. The script creates an iframe that loads the calculator from PropMetrics, plus a small attribution link underneath. Everything runs in your visitor's browser — no API keys, no backend setup, no data sent to any server. Visitor inputs stay in their browser.
The embeds are responsive and work on desktop, tablet, and mobile. Set a fixed width or use 100% to fill the container. The height is preset per calculator, but you can tweak it in the code if needed.
PropMetrics gives you rental comps, rent estimates, market data, and Fair Market Rent lookups for any U.S. address. Try it free.
