The Balance column shows the loan balance at the beginning of the month. The Principal indicates the portion of the month\'s payment that goes towards reducing the loan amount. The Interest column indicates the portion of the month\'s payment that is interest charges. The "Payment" column shows the cumulative amount that has been paid on the mortgage, principal plus interest. The Total Int column shows the cumulative amount of interest paid.
