Late Fee Calculator
Find out if a late fee is within your state's legal limit — and whether the grace period has actually passed.
Count from the day rent was due. If rent was due the 1st and today is the 8th, enter 7.
Enter the flat dollar amount being charged as a late fee.
How This Calculator Works
Enter your state, rent amount, how many days late rent is, and the fee your landlord is charging. The calculator will:
- Check whether the grace period has even expired — if not, no fee should be owed yet.
- Calculate the total fee being charged (flat, percentage, or daily × days late).
- Compare it against your state's statutory cap (if there is one).
- Show you whether the fee appears to be within legal limits, over the cap, or in a state with no cap.
Note: State laws change. Always verify the current rules in your state before acting on this result.
Draft a State-Compliant Lease Agreement
The easiest way to avoid late fee disputes is to start with a lease that already reflects your state's grace period and cap requirements. Get a completed, ready-to-sign document for your state in minutes — $7.99.

No — not in most states. Many states cap late fees at a percentage of monthly rent (commonly 5–10%) or a flat dollar amount, whichever is lower. Even in states without a statutory cap, courts can throw out fees that are "unreasonable" or punitive. The fee must also usually be written into the lease before the landlord can charge it.
A grace period is the number of days after rent is due that a landlord must wait before charging a late fee. For example, if rent is due on the 1st and your state requires a 5-day grace period, a late fee cannot legally be charged until the 6th. More than half of US states have a mandatory grace period — typically between 3 and 15 days.
No. Roughly half of US states have no statutory cap on late fees and simply require that fees be "reasonable." However, even in those states, a court can strike down an excessive fee as an unenforceable penalty. When in doubt, the fee should closely reflect the landlord's actual administrative cost of chasing late rent — not a windfall.
Some states allow daily late fees but cap how much can accumulate per month. For example, Oregon caps total accumulated late fees at 6% of monthly rent and limits the daily rate to 6% of the flat fee. Other states like North Carolina explicitly prohibit daily late fees. Check your state's specific rules using this calculator.
Technically, a landlord can begin eviction proceedings for non-payment of a lawful late fee in most states. However, courts often look unfavorably on evictions driven primarily by late fees rather than unpaid rent. If you believe the late fee is illegal, pay your rent on time and dispute the fee in writing — do not withhold rent over a fee dispute without legal advice.
In most states, yes. A landlord generally cannot charge a late fee unless it is explicitly stated in the written lease agreement — including the amount and when it kicks in. If your lease is silent on late fees, the landlord typically cannot add one mid-tenancy without your written agreement.
Start by checking your lease to confirm no late fee was agreed to, or that the amount exceeds what the lease says. Then write a polite letter citing your state's law. If the landlord insists, you can file a complaint with your state's tenant rights agency, withhold the excess amount (but NOT the rent itself), or seek help from a local tenant advocacy group. Keep records of everything.
A state-specific, completed lease agreement will include a late fee clause that already reflects your state's grace period and cap requirements. That way both you and your landlord are starting from a legally sound baseline — no guesswork required.
