How this calculator works
Periodic fees = min(verified chargeable periods × fee per period, entered total fee cap). Entered charges = unpaid rent + periodic fees + independently verified other costs. Balance = max(charges − allocated payments, 0).Worked example
Unpaid rent of 900 with three fee periods at 20 reaches a fee cap of 50. Add 30 verified other costs for 980 charges, then subtract 100 payments for 880 estimated balance.Assumptions
Defaults are illustrative. Replace them with your own measured quantities and documented assumptions. Use matching periods and a consistent currency wherever monetary amounts are entered.Interpreting your results
This does not determine fee legality, notices, lien rights, auction eligibility or payment-allocation rules. Confirm all entered amounts and periods independently. No interest or fee compounding is added.Calculation formulas
- fee
MIN(periods*fixed,cap)- balance
MAX(rent+fee+costs-payments,0)- Balance after entered payments
balance- Fees after applying the cap
fee- Total charges before payments
rent+fee+costs
Frequently asked questions
What should I check before using the result?
Use the applicable agreement and rules to establish which periods may be charged after grace. If a fee has been waived, enter the permitted effective amount. Do not use these defaults as an operator policy.
Does this tool connect to my records?
No. This is a local calculation from the figures you enter. It does not scan accounts, import private records or verify legal, regulatory or exam requirements.
