Can I calculate this question on BA II Plus Calculator? I try to calculate it by putting in N=5, I/Y=15 PV=-92.79, PMT=10, and CPT FV. But the answer is so different, and I try to calculate the rate in the same way, but it is also wrong. Why I can’t calculate this question in this way?
I don’t have my BAII with me, but I’ll outline the steps:
- Calculate the accumulated value of the coupons
P/Y 1 C/Y 1
5 N 15 I PMT 10 CPT FV (should be -67.42 or very close)
- Add -100 to the FV
RCL FV (-100 =) FV (should now be -167.42)
- Calculate I
92.79 PV 0 PMT CPT I (should be 12.53 or close)
I’ll try it on my calculator when I get home.
ETA: It works!!

Hello,
Thank you so much for your answer.
However, in this step: P/Y 1 C/Y 1
5 N 15 I PMT 10 CPT FV , I got FV=119.21.
Not sure what went wrong.
Try a 2nd CLR TVM first to clear out all the variables; make sure your calculator is in END mode for the annuity calculation.
