Interest Calculation Reference

Overview

CaseMark's Interest Calculation Reference automates the complex process of computing and validating pre-petition interest for U.S. bankruptcy creditor proofs of claim. It handles rate source determination, day-count methodology, charge inclusion decisions, and post-petition interest rules across all claim types. The result is a court-ready interest worksheet backed by a comprehensive validation checklist.

Calculating pre-petition interest for bankruptcy proofs of claim is tedious and error-prone. Attorneys and paralegals must manually determine the correct rate source, apply the proper day-count convention, calculate accrual days, evaluate fee inclusion, and verify arithmetic—all while navigating different rules for secured, unsecured, and priority claims. A single miscalculation can result in claim objections, reduced recoveries, or sanctions.

CaseMark automates the entire pre-petition interest calculation workflow, from extracting key data points in your loan documents and payment histories to applying the correct rate hierarchy and day-count methodology. The AI generates a validated interest worksheet with a built-in checklist that flags potential issues, so you can file or challenge proofs of claim with confidence and precision.

How it works

  1. 1. Upload your loan documents, payment history, and proof of claim filing

  2. 2. AI extracts principal balances, rates, dates, and fee provisions

  3. 3. Review the calculated pre-petition interest, rate source hierarchy, and charge inclusion decisions

  4. 4. Export the validated interest worksheet and checklist in your preferred format (DOCX, PDF)

Questions

What day-count methods does this skill support?

CaseMark supports 365-day, 360-day, and 30/360 day-count conventions. The AI identifies the correct basis from your loan documents and applies it consistently throughout the calculation.

Can this handle both secured and unsecured claims?

Yes. CaseMark analyzes secured, unsecured, and priority claims, applying the correct post-petition interest rules and charge inclusion standards for each claim type.

How does the AI determine which interest rate to use?

CaseMark follows a strict rate source priority hierarchy: contract rate first, then judgment rate, state statutory prejudgment rate, and finally the federal §1961 rate as a fallback. It documents the rationale for the selected rate.

Can I use this to audit or object to an opposing party's proof of claim?

Absolutely. CaseMark's validation checklist flags discrepancies in rate selection, day-count methodology, fee inclusion, and arithmetic, giving you a detailed basis for claim objections.

Does this account for late fees, attorney fees, and other charges?

Yes. CaseMark applies a charge inclusion gate that evaluates each fee category against contractual provisions and statutory authorities to determine whether it should be included in the total claim amount.

How accurate are the calculations compared to manual work?

CaseMark applies the exact formulas and rate hierarchies used in bankruptcy practice, eliminating common manual errors in date calculations, day-count conversions, and rate selection. Every output includes a full audit trail for verification.
