A borrower has a loan with the following details:

$500,000.00 Gross Loan, 10.75% APR, $375,000 Construction Escrow Holdback, $15,000 Prepaid Interest Balance. This is a non-dutch loan, meaning that the borrower is only going to accrue interest on what has been disbursed to them. At Closing, we hold back (or do not disburse) the Construction Escrow of $375,000. A draw is taken on the 50th day after origination in the amount of $60,000. On day 100 of the loan's term, what is the Prepaid Interest balance? Please show your calculations within an excel spreadsheet.
