This is for a friend. I believe I have found his bank did a miscalculation. Of course he calls me cuckoo
.
He took this loan of $40,950 in 2005, for 15 years, at 7.37% fixed APR.
(I made him call them and confirm these numbers just now).
He has been paying a constant monthly amount of $282.84 for all these years.
Of this, as of now, (they told him) the interest is $222, and $60 is principal. Balance left over today is around $38000.
According to the Excel formula PMT, his monthly payment should have been a constant $376.59, in which interest is $206.70 and principal is $169.90 (this month, as the ratio changes every month).
The formula is PMT ( 7.37% / 12 , 180, 40950 ).
I check with a couple of sites online, and they match Excel.
So what's going on? what went wrong, and where? Is he really underpaying, and it might come back to bite him? Or is there any other way to calculate this?
I did some what-if compares, and this could have happened if somebody had mistakenly typed in $30,755 in the original formula leaving everything else the same. But then the balance today would show much less!
Or, if the APR was wrongly entered as 3.00%, other things stay same. Again, the balance would be much less today.
Or am I really cuckoo?
He does not want to find out that he should really be paying more, so he's already left for home
