Please confirm that you have entered the correct dates and original grant amount. This tool is designed to calculate repayments based on the Bank's repayment calculation formula. Calculations by this tool are believed to be accurate, but we do not guarantee such accuracy and the results do not constitute the official final repayment amount for any grant. The member institution is still responsible for the actual full repayment amount or for returning any overage to the homebuyer, if applicable. Please contact the Community Investment Group at (312) 565-5336 if you need further assistance in calculating a repayment amount. The official final repayment amount will not be determined until all applicable documents regarding the repayment have been received by the Federal Home Loan Bank of Chicago.  Calculate Repayment This calculator is NOT for use by consumers, homeowners or anyone other than FHLB Chicago member institutions.   Original Grant Amount: Original Closing Date: Payoff Date:
