Late rent notice builder
Before you send it: this builds a reminder letter about overdue rent and a late charge. It is not an eviction notice. A notice to pay rent or quit is a separate document, and Arkansas has its own rules for it. Nothing on this page is legal advice.

Still unpaid? Generate a formal demand letter — it computes the interest and cites Arkansas's statute (Ark. Const. amend. 89; Ark. Code Ann. § 4-57-101(d)) for you.
Worked example: Arkansas invoice interest at 6%
Interest at Arkansas's statutory default of 6% a year, worked out with the same formula as the calculator above: amount × (6% ÷ 365) × days. If your contract states its own rate, enter that rate in the calculator instead.

The Invoice tab, the rate card and the statute sections on this page are about business-to-business invoices. Residential rent late fees live in Arkansas's landlord-tenant law. Arkansas: Ark. Code 18-17 contains no late fee provision, so there is no legal cap or waiting period to apply; only your lease terms count. Consumer credit has separate, stricter rules. The distinction is explained in B2B invoice late fees vs. residential rent.
