I have calculated loan payments with this Program on the HP65 and believe the results to be correct.
However, when attempting to calculate the same using an HP80 I get different results. So I think I am not using the HP80 correctly.
So, if I have a number of periodes, an interest rate, and the annuity, how can I calculate the ammount borrowed?
For example:
I have 12 payments a year for twenty years, 1,9% anual interest rate and 1200 Euros Anuity, on the 65 I would do this:
20
Enter
12
A
1.9
B
1200
D
E
C
What do I do on the 80?
Cheers,
Harald
