Is there a legal limit on late fees in Missouri?

No statutory cap (see reasonableness standard and notes). Missouri sets no statutory formula, percentage, dollar cap, or grace period for residential rentals. Enforceability rests on ordinary contract law. A late fee must be an agreed term, and courts refuse to enforce amounts that operate as penalties rather than reasonable pre-estimates of loss.

Can a landlord charge a daily late fee in Missouri?

No statute addresses residential late-fee structure at all, so daily or flat fees are lease matters, bounded only by common-law liquidated-damages and penalty doctrine.

What late fees can a landlord charge in Missouri?

Verified July 9, 2026 All Missouri topics →

Missouri sets no cap on residential late fees and mandates no grace period — no statute in the landlord-tenant chapters (RSMo 441 and 535) mentions late fees at all, so the fee is whatever the lease says, subject only to the court-enforced rule that a late fee must be a reasonable pre-estimate of the landlord's loss rather than a penalty.

Rent is due on the date the lease sets, and under RSMo 535.060 a landlord's demand for rent is valid any time after it comes due, so a lease-based late fee can begin the day after the due date. Two figures that circulate online do not apply to homes or apartments: the '$20 or 20 percent of monthly rent' safe harbor is RSMo 415.417, part of Missouri's Self-Service Storage Facilities Act covering storage units only, and claims that RSMo 535.060 'governs late fees' are wrong — that section is about when a demand for rent is valid and never mentions fees. A fee that appears nowhere in the lease has no contractual basis to be collected.

Missouri late fees at a glance

Statutory cap	No statutory cap (see reasonableness standard and notes)
Mandatory grace period	None mandated statewide
Must be in the lease	Not addressed by statute
Daily fees	No statute addresses residential late-fee structure at all, so daily or flat fees are lease matters, bounded only by common-law liquidated-damages and penalty doctrine. The '$20 or 20% of monthly rent, whichever is greater' figure that circulates in Missouri late-fee guides is RSMo 415.417, part of the Self-Service Storage Facilities Act (RSMo 415.400-415.425 by its own citation clause). It governs storage units, not homes or apartments.
Reasonableness standard	Missouri sets no statutory formula, percentage, dollar cap, or grace period for residential rentals. Enforceability rests on ordinary contract law. A late fee must be an agreed term, and courts refuse to enforce amounts that operate as penalties rather than reasonable pre-estimates of loss. Neither RSMo chapter 441 nor chapter 535's landlord-tenant provisions supply such a standard, and Missouri courts police late fees as liquidated damages. RSMo 535.060 confirms rent is due 'according to the terms of the agreement' and a demand for rent is good any time after it accrues, so no statutory grace period intervenes.

Notes and caveats

No late-fee statute at all — the blanks record silence, not zero — Missouri has NO late-fee statute of any kind for residential rentals, so there is no statutory cap, no grace period, and no statutory writing requirement. The empty fields here record that silence; they do not mean a zero fee or a zero-day grace period.
Why 'must be in lease' is blank rather than yes — A late fee does need an agreed term to be collectable — no agreed term, no fee — but that is a consequence of ordinary contract law, not a statutory command, so it is not presented here as a statutory requirement.
535.060 is not Missouri's late-fee law — RentLateFee.com falsely presents it as Missouri's late-fee framework. The section is titled 'Demand of rent good, when' and contains nothing about fees; it is cited here only because it fixes when rent is due and demandable.
The $20/20% figure belongs to storage units — RSMo 415.417 is cited here only to debunk it: its containing act self-identifies as the Self-Service Storage Facilities Act in RSMo 415.400. The figure governs storage units, not homes or apartments.
'4-5% is reasonable' is a rule of thumb, not a Missouri rule — Several sites repeat the figure with no Missouri statutory or reported-decision citation offered behind it. No percentage should be treated as a Missouri standard.
