# BA-II Plus calculator is consistently giving the wrong answer

I’ve had a BA-II plus calculator for an entire Theory of Interest course and now for Exam FM prep. I always clear TVM and Clear Work between each computation. I always follow the instructors key strokes. It is literally. never. right. Ever.

Here’s an example. I’m doing a problem for 2017 SOA FM exam. I want to solve for a 10000 par value 10 year bond with 8% coupons bought at premium to yield an annual effective rate of 6%. I want to find the book value of year 6.

I put 4 for N, 6 for I, 800 for PMT, and 0 for FV. I would expect this to yield 10693, however, for some reason, it yields 2772.08449. I cleared TVM, and cleared work multiple times. Each time I do it it yields this answer. I need to use this calculator for my June sitting and yet it seems completely useless and I will lose so much time doing computations by hand rather than by calculator.

From an oooooold FSA who knows your pain:

P/Y=C/Y=1 (annual coupon, annual compounding)
N 4 I 6 PMT 800 FV 10000 CPT PV -10,693.02112

You need to set FV to 10000 to reflect the redemption of the face amount at time 10.
