Flat fee of $50.00 once rent is past the 5-day grace period. Many states cap late fees or require a minimum grace period — confirm yours.
A number this calculator produces is not automatically a fee you may lawfully charge. Many states cap late fees, require a minimum grace period, or require the fee to be a reasonable estimate of your actual loss. Your lease must also authorise the fee in writing.
Let Ayillo apply your late fee policy automatically
Flat fee: one fixed amount once rent is late. Simplest to administer and easiest to defend.
Percentage of rent: a set percentage of the monthly rent. Scales with the unit but can grow large on expensive rentals.
Per-day: a daily amount that accrues while rent is unpaid, usually with a cap. Encourages fast payment but needs a cap to stay reasonable.

Frequently asked questions
Is there a standard late fee?
There is no national standard. 5% of monthly rent after a five-day grace is a common convention, but several states set lower caps or require the fee to reflect actual costs.
Can I charge a late fee if the lease does not mention one?
Generally no. A late fee normally has to be authorised by the lease to be enforceable.
