Free SBA Calculators You Can Put on Your Own Website

Six interactive SBA tools, free to embed on advisor, broker, lender, franchise-consultant, and association sites. Copy one snippet. They stay current automatically as the SBA updates its rules.

Every calculator below is free to embed on any website, commercial or not, with no signup, no API key, and no fee. The snippet includes a small credit link back to the source page. The math is verified against the current SBA SOP 50 10 8 and the SBA's Procedural Notices, and when the SBA changes a rule, the embedded tool updates on your site automatically because it renders from ours.

Why these exist

Most SBA calculators on the web either capture the visitor's contact details and sell them to lenders, or quietly use outdated thresholds. These do neither. They update themselves when the SBA changes a rule, the tools don't require an email to produce an answer, and each rule is tied to a primary source you can check yourself.

If you advise buyers, list businesses, or lend, an embedded tool answers the question that otherwise eats the first ten minutes of every call.

How to embed one

Pick a calculator below and copy its snippet.
Paste it into any page, post, or CMS block that accepts HTML.
That's it. The iframe sizes itself, and the credit line sits in your page's own HTML so it reads as a normal citation.

Works in WordPress (Custom HTML block), Squarespace (Code block), Webflow (Embed), Wix (HTML iframe), Ghost, and any plain HTML page. Please keep the credit link, it's the only thing we ask in return.
