Give your buyers the real monthly cost, free.

Copy the code

Paste this where you want the calculator to appear. Most website builders, including WordPress, Wix and Squarespace, have an “HTML” or “embed code” block for this. The short script lets the calculator grow as buyers open the results, so there’s no scroll bar inside it.

If your website only allows the frame and not the script, use just the first line and set the height to about 1,500 pixels.

What buyers get

• The full monthly cost for a house, condo or manufactured home, in any state.
• An address lookup that finds the county and FEMA’s flood zone.
• A property tax estimate in Florida, and steps for getting the real bill from the county elsewhere.
• Loan programs they may qualify for, with a section for military and veterans, plus their state’s down payment help.
• A plain-English snapshot with clear disclaimers. Nothing they enter is saved.

The fine print

• It’s free. No fees now or later, and we don’t pay or take referral fees.
• Keep it as it is. Please don’t change the code, hide the Know Before You Own credit or put the calculator behind a sign-up form.
• No endorsement. Showing the calculator doesn’t mean Know Before You Own recommends you, and we don’t recommend agents, lenders or other companies.
• Education only. The calculator is general education, not a loan offer or financial advice. Property tax amounts are estimates.
• Updates are automatic. When we update the calculator, it updates on your site too.
