amoritization schedule with periodic payments and balance due
I borrowed $25,000 for 24 months, agreed to pay back $35000 in a single balloon payment at the end of the 24th month. However, what actually occurred is this: I made a $1200 payment the first day the loan was given. I made a $500 payment after 30 days. I made another $500 payment on month 13, and on months 18 thru 24, I made (6) $500 payments. My question is what is the balance actually due using simple interest and with the periodic payments made?
