The ceiling

How high can a late fee go in Alabama?

Your contract decides. The rate above only applies when your terms are silent. Between businesses, an agreed late-interest rate or late fee replaces it, within two limits: the state's ceiling on agreed rates, and the rule that a late fee must compensate you rather than punish the customer.

Alabama's ceiling: No limit on an agreed rate where the principal is $2,000 or more (Ala. Code § 8-8-5).

On smaller invoices, check Alabama's general limit before using the common 1.5%-a-month (18%) rate.

Late payment wording for a Alabama invoice

On your invoice

Payment is due by the date shown on this invoice. Late payments are subject to interest at 6% a year, the legal rate under Ala. Code § 8-8-1.

This restates what Alabama law applies when your contract is silent. If your contract sets a rate, quote that instead. The wording doesn't say when interest starts, because that differs by state; the note at the top of this page covers it where Alabama law sets it.
