Accrued Interest, BA II Plus Professional

Good Morning

I have the following example of accrued interest:

Last Coupon Payment date: 7 May 2017

Today date: 15 September 2017

Anual Payments: 2

Convention: 30/360

Anual Rate: 8,75%

Residual Value: 100%

The correct answer is that the accrued interest is = $3,21 (4,375*(132/180)*100)

I introduced:

SDT: 7.0517 (European date)

CPN: 8,75

RDT: 15.0917

RV: 100

Convention: 360

Payments: 2/Y

YLD: Computer Enter

PRI: Computer Enter

Accrued Interest: 1,26389

Where is my mistake?

Why can I arrive to the correct figure of 3,21?

Thanks

RDT is the bond redemption date, not the settlement date. Just as a plug figure, I used 7 May 2018. Using your inputs, I get AI=3.1111111

3.111111 = 0.04375 * (128/180) *100 (131 is the actual day count, 128 is the count using 30/360)

Thanks for your answer
It is so clear and correct your answer, but I wanted to get the answer of the AI, using the Bond function of the BAII Plus Professional
The point is how I get the $3,11 AI, as of the 15 Sept 2017
What data should I introduce to get the correct answer.
Thanks

Set RDT as 7 May 2018 ( or any future coupon date) and SDT as 15 Sept 2017. All your other I puts are correct! :vulcan_salute:

Perfect, thanks a lot!
