Late Rent Fee Calculator (Free): CA, TX, FL and NY Rules
A late rent fee is the charge your lease allows when rent arrives after the due date and any grace period. Pick your state, enter the rent, your lease fee and the dates, and the calculator shows the fee you can charge. It also checks the state rules for California, Texas, Florida and New York.
Late Rent Fee Calculator
How do you calculate a late fee on rent?
Start counting only after the due date and any grace period in your lease or state law. Then use the method your lease sets. Most leases use one of these three:
| Late fee type | How to calculate it | Example |
|---|---|---|
| Flat fee | One fixed amount once rent is late | $50 |
| Percentage of rent | Monthly rent x the percentage | $1,400 x 5% = $70 |
| Daily fee | Days late x the daily amount, up to any cap | 4 days x $10 = $40 |
How does the late fee calculator work?
- It counts the days late. The number of days between the rent due date and the day rent was paid.
- It finds when the fee can start. That is the day after your lease grace period ends, or after the state waiting period if the state requires a longer one. New York requires rent to be more than 5 days late. Texas requires rent to be unpaid for two full days after the due date.
- It adds up the fee. The flat amount or the percent of rent in your lease, plus any daily fee for each day after the first fee day.
- It checks the state limit. New York caps the fee at $50 or 5% of rent, whichever is less. Texas presumes a fee is reasonable up to 12% of rent for a building with 4 or fewer units (10% for larger buildings).

Late fee examples
All examples use rent of $1,400 due on 10/01/2026.
| State | Lease fee | Rent paid | Late fee you can charge |
|---|---|---|---|
| New York | $75 flat | 10/06/2026 (5 days late) | $0.00, not more than 5 days late yet |
| New York | $75 flat | 10/07/2026 (6 days late) | $50.00, the state limit (5% would be $70) |
| Texas, duplex | 5% plus $10 a day | 10/04/2026 | $70.00, under the $168 safe amount |
| Texas, duplex | 5% plus $10 a day | 10/20/2026 | $230.00, above the $168 safe amount |
| California | $75 flat, 5 day grace | 10/07/2026 | $75.00 |
The Texas example shows why daily fees need care. In Texas the first fee and the daily fees are added together and treated as one late fee, so a long late period can push the total over the safe amount. Many landlords set a maximum total in the lease to avoid this.
How do you record the late fee?
Add the late fee as its own charge line in your rent ledger, dated the day the fee applies. Never change the rent amount. When the tenant pays, give a rent receipt that shows rent and late fee on separate lines. If the tenant pays only part of the amount, follow our guide to partial rent payments.
Note: This calculator is Late fee rules change and vary by state and city. Check your current state and local rules, or ask a local attorney, before you charge a late fee.
Frequently asked questions
Does the calculator count weekends and holidays?
It counts calendar days, including weekends and holidays. Some leases move the due date when it falls on a weekend or holiday, so check your lease and adjust the due date if needed.
What if my lease grace period is shorter than the state rule?
The state rule wins. In New York, for example, a late fee is not allowed until rent is more than 5 days late, even if the lease says 3 days. The calculator uses whichever period is longer.
My state is not listed. Can I still use it?
Yes. Choose Other state and the calculator applies your lease terms. It cannot check your state limit, so look up your state law before you charge the fee.
Can I charge a late fee on a partial payment?
If your lease allows it and part of the rent is still unpaid after the grace period, a late fee can usually apply. Texas, for example, allows the fee once any part of the rent is unpaid two full days after the due date.
