Calculate a late rent fee using a flat amount, a daily rate, or both — capped at a maximum you set.
Flat + daily structures are the two most common late fee formats — a one-time flat charge once rent is late, a per-day charge that accrues the longer it goes unpaid, or a combination of both, as this calculator supports.
Many states cap late fees as a percentage of monthly rent or a fixed dollar maximum, regardless of what your lease says — a common (though not universal) benchmark is around 5% of monthly rent. Setting a cap percentage here lets you see the fee before and after that limit is applied.
Your lease must actually authorize the fee you're charging — a late fee isn't enforceable just because you calculate one; it needs to be specified in the signed lease and comply with your state and local law.
