Missouri late rent fee: the legal maximum
Missouri sets no statutory cap on late fees. The amount is whatever the lease says, subject to the general rule that it must not be an unconscionable penalty. There is no statutory grace period, so the lease controls when the fee starts.
Reference: 5% of rent at common rents
Missouri has no cap. Five percent of monthly rent is the most common lease figure and the statutory cap in several other states; it is shown for comparison only.
| Monthly rent | 5% reference |
|---|---|
| $1,000.00 | $50.00 |
| $1,500.00 | $75.00 |
| $2,000.00 | $100.00 |
| $3,000.00 | $150.00 |
What the statute says
No statutory cap or grace period; late fees are enforceable only if provided in the lease and reasonable under general contract (liquidated-damages) principles.
How this applies in practice
- A late fee must be written into the lease. The statute constrains what the lease may say; it does not create a fee on its own.
- With no statutory grace period, the lease decides when the fee starts; many leases allow three to five days.
- Courts treat a late fee as liquidated damages: it must approximate the landlord’s real cost of late payment. Fees far above 5% of rent, or that compound daily without limit, are the ones that get struck down.
- Late fees are separate from interest on unpaid rent and from eviction filing costs, which have their own rules.

Frequently asked questions
What is the maximum late fee for rent in Missouri?
There is no statutory maximum in Missouri. No statutory cap or grace period; late fees are enforceable only if provided in the lease and reasonable under general contract (liquidated-damages) principles. The most common lease figure nationally is 5% of monthly rent, and courts in no-cap states generally accept fees in that range while rejecting ones that look like penalties.
Is there a grace period for rent in Missouri?
Not by statute. The lease may set one; if it is silent, a fee can be charged the day after the due date.
Can a Missouri landlord charge a daily late fee?
Nothing in state law forbids it, but the total must remain reasonable. A daily fee that quickly exceeds a few percent of rent risks being struck down as a penalty.
Can a landlord charge a late fee that is not in the lease in Missouri?
No. A late fee is a contract term. If the lease does not provide for one, the landlord cannot impose it, and in Missouri the statutory reasonableness standard applies on top of whatever the lease says.
