Late Fee Calculator

Initial fee = flat amount, or monthly rent × percent ÷ 100
Total late fee = initial fee + daily fee × days charged
State ceiling = the state's percent of rent, flat amount, or the greater or lesser of the two, as its statute says

• Initial fee is the one-time charge once the grace period ends. Leases write it as a flat amount or as a percent of the monthly rent.
• Daily fee is an optional extra charge for each additional day rent stays unpaid. The calculator adds every daily fee to the initial fee before comparing with the state figure.
• State ceiling comes from the cited statute in our state-law data. The calculator applies it to one full month's rent, as if the whole payment were late. Where a rule has tiers, depends on the building, or is set by case law, there is no single figure and the page shows the rule text instead. 15 of the 51 jurisdictions in the data produce a single figure.

The calculator starts with $1,600 monthly rent and a lease that charges 5% of rent once rent is late, plus $10 a day for 3 more days.

1. Initial fee: $1,600 × 5% = $80.00.
2. Daily fees: $10 × 3 = $30.00.
3. Total: $80.00 + $30.00 = $110.00, or 6.9% of the rent.

The same fee checked against three kinds of state rule:

• Percent of rent. Tennessee: In URLTA counties, a late fee, however described, may not exceed 10% of the amount of rent past due (Tenn. Code Ann. § 66-28-201(d)). On $1,600 rent the ceiling is $160.00, so the $110.00 example fee is within it.
• Lesser of a dollar amount or a percent. New York: A late fee may not exceed the lesser of $50 or 5% of the monthly rent (N.Y. Real Prop. Law § 238-a(2)). On $1,600 rent the ceiling is $50.00, so the $110.00 example fee is $60.00 too high.
• Greater of a dollar amount or a percent. Colorado: A late fee cannot exceed the greater of $50 or 5% of the past-due rent, must be stated in the lease, and cannot be charged more than once per late payment beyond that total (C.R.S. § 38-12-105(1)(b), (c), (g)). On $1,600 rent the ceiling is $80.00, so the $110.00 example fee is $30.00 too high.

Same lease, three different answers. That is why the fee belongs in the lease only after you check the rule for the state where the property is.

Where a state sets a cap, stay at or under it, counting every daily fee. Where it does not, courts in many states look at whether the fee is a reasonable estimate of what late payment costs the landlord rather than a penalty. A fee that is small next to the rent, stated clearly in the lease, and charged the same way to every tenant is easier to defend than a large one or one that keeps growing.

A late fee only helps if tenants know it is coming. Put the due date, the grace period, the fee and any daily fee in the lease (the lease agreement generator asks for each one), and send a late rent notice when rent is late. The late fee laws by state page lists every state's rule side by side.

• Adding daily fees with no end date, so the total eventually passes the state cap or looks like a penalty.
• Charging a late fee before the grace period in the lease or state law has run out.
• Charging a fee that is not written in the lease.
• Taking the late fee out of a partial rent payment first and then calling the rent unpaid. Read your state's rule on partial payments.
• Using a cap from another state, or a city's cap, without checking which rule applies to the property.
• Calculating a percent fee on rent plus utilities or other charges when the rule is based on rent alone.

A late fee is not a substitute for a written notice. Most eviction processes start with a notice that gives the tenant a set number of days to pay, and that period is separate from the grace period. Send the late rent notice with the rent due, the late fee and the total, and record the payment with a rent receipt once it comes in.

Before the next lease, check that the applicant's income comfortably covers the rent with the rent-to-income ratio calculator.

Does every state cap late fees?

No. Some states set a percentage, a dollar amount, or a formula in statute. Others have no statute and leave it to the general rule that a late fee must be a reasonable estimate of the landlord's costs rather than a penalty. Pick your state in the calculator to see what the state-law data shows, with links to the statute.

Do daily late fees count toward the cap?

Treat them as if they do. This calculator adds the initial fee and every daily fee together and compares the total with the state figure, which is the cautious reading. Read your state's rule for how it treats daily fees, partial payments and repeated late payments.

What is a grace period?

A grace period is the number of days after the due date during which rent can be paid without a late fee. Some states require one by statute; elsewhere it is up to the lease. If your lease gives a longer grace period than the state requires, the lease controls.

Can I charge a late fee that is not in the lease?

Generally you should not. Late fees are usually enforceable only when the lease states them, and several state statutes require the fee to be in a written agreement. Put the amount, when it starts, and any daily fee in the lease, and send a written late rent notice when rent is late.

Does a city's rule override the state cap?

It can. Some cities and rent-regulated buildings set lower limits than state law. The state figure here is a ceiling under state law only; check local rules for the property's address.
