Interest Estimator

To allow banks to estimate interest on a prior period adjustment, the FDIC is making available a spreadsheet (“Interest Estimator”) on which a bank may enter its originally reported and amended information. The Interest Estimator contains interest rate information going back three years and will estimate the interest that will apply based on information that a bank enters.

Download the Interest Estimator - Excel (Excel Help) updated as of June 12, 2024.

Disclaimer: The Interest Estimator does not purport to predict actual interest amounts for underpayments or overpayments and should not be so construed. The purpose of this workbook is to allow an institution to estimate the interest amount on an overpayment or underpayment.
