You are missing a part of the overall premise on an amortizing note payment… that being recapture of a portion of his invested funds, as a part of each monthly payment!
In your example here, after receiving the first payment of $184.66 ($82.81 of which is interest), the remaining $101.85 of that payment has gone back into your buyer’s jeans. Now he only has $4,866.99 invested in that note. This same process continues all the way through the amortization of the note.
In month two, of that $184.66 payment, $81.12 goes to the interest on the note, while the remaining $103.54 from that payment goes right back into his jeans as another partial recapture of his original invested funds. So, after the end of month two, Mr. Investor now only has $4,763.45 remaining invested in this note.
Similarly, in the 12th month, he receives interest earnings of only $62.51 on a remaining balance (of his invested funds) of only $3,750.36. This continues until the note is fully paid off.
That is the underlying principle of a level payment amortizing loan schedule. Unlike an “interest-only”, or straight note “principal plus interest all due at some future date”, each payment in an amortizing note (or loan) includes interest on the then outstanding balance still due on the note, plus a portion of the original principal amount. So the investors dollar investment in the note declines a little each succeeding month.
Hope that helps, and best wishes for your success on this deal.
