A delinquent installment, an event of default and a cured loan are different states. Calculate each charge only after identifying its trigger and contractual basis.
When a commercial loan payment is late, the next amount due may include more than the missed installment. The important questions are which event occurred, which balance bears additional interest, whether a separate charge applies and how the lender credits the next payment. Sending the original installment does not by itself establish that every default or outstanding amount has been resolved.
Build an event record before building a dollar estimate. Include the due date, funds-received date, relevant cutoff, notice date, any cure period and the lender’s stated status. Ask counsel to distinguish a late-payment fee from an event of default and acceleration. Their triggers may be different, and applicable law can affect enforceability.
Separate three calculations
The historical Block 40 agreement dated June 1, 2022 separates default interest, late charges and payment rules in Sections 2.2.2 and 2.3. This illustrates document structure, not a nationwide fee rule or an interpretation of another loan.
Start with ordinary interest accrued on the applicable balance. Then calculate any incremental default-rate amount for the period and base the operative clause permits. Finally, identify one-time charges, reimbursable costs and other obligations separately. This prevents an all-in default rate from being added on top of ordinary interest a second time.
A clause stating an 11% default rate is different from a clause adding 11 percentage points. A fee on an unpaid installment is different from a fee on the outstanding principal. A default-rate period measured from the event date is different from one measured from notice or demand. Record those distinctions explicitly rather than filling a generic “penalty” cell.
Worked exhibit: a hypothetical ten-day default period
Assume an invented agreement and an agreed account status with $2 million outstanding, a 7% ordinary rate, an 11% total default rate and actual/360 accrual. Assume the relevant default rate applies to principal for exactly ten days. A separately identified overdue installment is $15,000, and a hypothetical late fee equals 4% of that installment. Assume these charges are legally applicable and no interest accrues on unpaid interest or fees in this example.
| Item for the modeled period | Calculation | Amount |
|---|---|---|
| Ordinary interest for ten days | $2,000,000 × 7% × 10/360 | $3,888.89 |
| Incremental default interest | $2,000,000 × (11% − 7%) × 10/360 | $2,222.22 |
| Total interest for those ten days | $2,000,000 × 11% × 10/360 | $6,111.11 |
| One-time late charge | $15,000 × 4% | $600.00 |
The table’s ordinary and incremental interest sum to the total-interest row. Do not add all three. Nor should these illustrative ten-day accrual amounts automatically be added to the $15,000 installment: first determine which accrual period that installment already covers. Otherwise the same interest can enter the cure request twice.
The hypothetical default premium increases the principal’s daily interest cost by $222.22. A further fifteen days at the same balance would add approximately $3,333.33 of incremental interest. That is useful for comparing a documented funding delay, but it is not a substitute for a dated lender statement, especially if costs, rates or principal change.
Apply the payment before declaring the balance cured
Now use a separate, simplified cure ledger. Assume the lender and borrower agree that outstanding amounts are $15,000 of installment arrears, $2,222.22 of incremental interest, a $600 late charge and $900 of reimbursable costs. These amounts are assumed nonoverlapping. The total is $18,722.22.
If the borrower sends $16,000 and the hypothetical allocation order is costs, late charge, incremental interest, then installment arrears, the remaining installment arrears equal $2,722.22. The transfer exceeded the original installment but did not clear the agreed ledger. A different contractual allocation could leave different categories unpaid while producing the same total unpaid amount.
Retain confirmation showing actual receipt and allocation. A payment instruction, bank debit or wire confirmation answers a different question from the servicer’s application of funds. If a payment is held in suspense, credited after cutoff or applied to another obligation, the borrower should resolve that discrepancy promptly with the authorized recipient.
Check what money cannot cure by itself
A payment may resolve monetary arrears while a reporting failure, prohibited transfer or insurance problem remains. The event record should therefore include separate monetary and nonmonetary items. Obtain the relevant evidence for each: delivered financial statements, restored insurance, executed consent or whatever the actual agreement requires.
A lender’s acceptance of funds does not let the investor infer the scope of any waiver. Keep reservation-of-rights letters, written waivers and amendments with the operative loan documents. Counsel should assess their legal effect, including whether an acceleration must be rescinded or another formal action is necessary.
For an active delinquency, request a dated statement with its good-through date, per-diem amount, allocation method and any unresolved conditions. Reconcile that statement to the borrower ledger without delaying urgent communication over a minor arithmetic question. The intended outcome is a documented status and a funded response, with disputed items clearly identified rather than silently assumed away.
