Change the payments-per-year to 1 to get the correct answer. Press 2nd [P/Y] 1 ENTER.

To pay off a loan of $3245 at 12% annual interest, you can either make 6 monthly payments of $559.91 and pay it off in half a year or make 6 annual payments of $789.27 and pay it off in six years.

My calculator BAII Plus does not give correct answer when calculation is made what can I do?

Make sure all the settings are set the way you want them. Check especially the BEGIN/END setting and the P/Y value.

If this doesn't do it, could you reply to this post stating the exact values you're putting in and the answers you're getting?

I am using Texas BAII Plus. The problem is when I try to calculate the NPV, N, PV,PMT, FY. it does not provide the right figure. It was ok until this morning. I think I might press something wrong....

Check the BEGIN/END setting (2nd [BGN]) and the number of payments per year (2nd [P/Y]). If these are set correctly, could you post the problem you're trying to solve, giving both your results and the expected results?

Calculating PV where n=5; i=6%; $18,400=pmt; 0=FV.

Check to make sure you have the proper value set for payments-per-year.

Water damage

This is going to sound super dumb put leave it in a bowl of rice for a couple days. Rice will obsorbe the water. Also, change all five of the batteries(the 4 AAA ones and the back up battery). And if that doesn't work, you're pretty much out of luck. However, don't rush to the store and buy a new calculator. If you're in college or know someone that is in college, do what I do. Go to a math or sicence lab professor and ask them for a calculator at the end of the semester. I'm getting a new 89 pretty soon and i'm kinda excited. Good luck with your calculator

Changing batteries and life span

It's written in the back of the calculator, mate ! A TI BA ii Plus uses a CR2032 battery, which is 3V, 60 micro A.
Just go to the shop and give them the battery model.
