All contracts for the payment of interest [...] at a higher rate of interest than the equivalent of 18 percent per annum simple interest are hereby declared usurious. However, if such loan [...] or obligation exceeds $500,000 in amount or value, then no contract to pay interest thereon is usurious unless the rate of interest exceeds the rate prescribed in s. 687.071.

B2B invoices only — not rent, not consumer debt

Everything on this page is about business-to-business invoices. Residential rent late fees live in Florida's landlord-tenant law and consumer credit has separate, stricter rules — two different bodies of law. The distinction is explained in B2B invoice late fees vs. residential rent.

No. This page covers business-to-business invoices only. Residential rent late fees are governed by Florida's landlord-tenant law, and consumer credit for personal, family, or household purposes has its own stricter caps and disclosure rules. Those are different statutes than the commercial-interest law cited here.

Where does this data come from, and when was it verified?

The operative legal text is quoted verbatim on this page with a link to the official source, the methodology is public, every verification pass is logged in the changelog, and the full dataset is downloadable (CC BY 4.0).

This page summarizes Florida's commercial-interest statute for general information, with the verification date shown above — it tells you when we last confirmed the figures, not that they are still current today. Statutes change and courts interpret them; verify the cited statute at the official source, or ask a licensed attorney in your state, before charging or demanding interest.
