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 Missouri courts enforce a clause that fixes damages in advance only as liquidated damages: the amount must be a reasonable forecast of the harm the breach causes, and the harm must be of a kind difficult to estimate accurately; a penalty clause is invalid (Paragon Group, Inc. v. Ampleman, 878 S.W.2d 878 (Mo. Ct. App. 1994), which upheld a termination fee in a residential lease).

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 by the court-made rule that a clause fixing damages in advance is enforced as liquidated damages and not as a penalty.

What late fees can a landlord charge in Missouri?

Verified October 2, 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 to the court-made rule that a clause fixing damages in advance is enforced only if it is a reasonable forecast of the 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 by the court-made rule that a clause fixing damages in advance is enforced as liquidated damages and not as a penalty. 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 Missouri courts enforce a clause that fixes damages in advance only as liquidated damages: the amount must be a reasonable forecast of the harm the breach causes, and the harm must be of a kind difficult to estimate accurately; a penalty clause is invalid (Paragon Group, Inc. v. Ampleman, 878 S.W.2d 878 (Mo. Ct. App. 1994), which upheld a termination fee in a residential lease). Neither RSMo chapter 441 nor chapter 535's landlord-tenant provisions supply such a standard, and no Missouri appellate decision on a residential late fee is cited here; the rule above comes from a lease termination fee. 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 — Some online summaries present it as Missouri's late-fee framework, which it is not. 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.

How this record was verified: Direct read of statute text on the official Missouri Revisor of Statutes site (revisor.mo.gov), read again on October 2, 2026 with each page's effective date and history line: RSMo 535.300, 441.043, 441.050, 441.060 and 700.600; 535.060, 415.400 and 415.417; 441.020 to 441.040, 441.065, 441.233 and 441.560; the rent and possession and unlawful detainer sections of chapters 535 and 534, with 535.012, 535.050, 535.200 and 535.210; the expedited procedure of 441.710 to 441.880; 701.308; and the time-computation sections 1.040 and 506.060. The section lists of chapters 441, 534, 535 and 700 were read for the negative answers: no section of chapters 441, 534 or 535 sets an entry notice, a late fee or a rent-increase notice, and the one limit on rent increases is RSMo 700.600.2, for manufactured and mobile home land lease communities. The Senate's Truly Agreed To and Finally Passed lists for 2024, 2025 and 2026 (102 bills in 2026) were read with the bills' pages and truly agreed texts: no 2026 act changed an answer on security deposits, late fees, entry, rent increases or eviction, and the 2025 amendments to 441.043 (H.B. 595 & 343, effective August 28, 2025) are in force and incorporated. Paragon Group, Inc. v. Ampleman, 878 S.W.2d 878 (Mo. Ct. App. 1994), was read in the reporter.
