 # inverse outstanding interest

you take a car loan worth 10k, for 6 years and make monthly payments. The going annual rate of interest on such loans is 5%. How much interest will you have LEFT to pay after 3 years.

I guess we need AMORT function in calculator, but don’t know how to do. Also it is not required for L1, right?

PV 10,000 N 6*12 = 72 I/Y 5/12 Cpt Pmt 2nd Amort P1- 1 P2 - 36 Bal - 5374 Prn - 4626 Int - 1171 Bal 5374 is the Answer This sure is a L1 problem. Here is what they may ask. Is interest greater or less than principle in the early years of a loan? Ans - Loan amortization means Interest is paid first, then Principle. Think of it like a box. Draw a line from the top left corner to the bottom right corner. The bottom is interest, the top is principle. Thats how amortization works.

I got the answer as 425.21 but i am using excel, need to learn how to do this with calculator, using 12c here.

Is mine correct?

I mean L1 may not require you to use ARMOT function in exam. Of course, we need to understand the concept. If it asks for first few periods interest, I can do with pen and paper.

Hmm…can anyone contest what I’m doing wrong?

Ok, now I got \$424.25 You set P1 - 37 P2 - 72. This is the amount left after 3 years.
