Solved!

10b11+ giving incorrect answers

HP Recommended
HP 10b11+

My calculator is giving incorrect answers. Example: What will a deposit of $4,500 at 10% compounded semiannually be worth if left in the bank for six years?

Pv: 4,500

i/yr 10%

n: 6

pmt: 0

FV: solve. 

 

It gives me -4,729.74. This is not the correct answer. What do I do when I have a test coming up in 5 days?

Hi,

 

for semi-annual you need to set payments per year to 2.

 

2 Orange-shift P/YR (on PMT key)

 

Also remember that  then N becomes 12 (there are 12 semi-annual interest payments in 6 years)

 

You can do this with the xP/YR (on N key)

 

6 Orange-shift xP/YR  (the display will show 12 which is automatically stored in N )

 

You should now get a FV of -8,081.35, which I think is the answer you were expecting.

 

 (edited to correct spelling)

Note that the source of 99% of errors in financial calculations stems from not having your interest match your compounding correctly as specified. Make sure you are doing that correct, and the rest is easy!

 

I always tell finance students - learn how to interpret interest and compounding correctly before anything else and REALLY understand it. That will make the course simple.
