Hi,
I have a BA II Plus Professional calculator from Texas Instruments.
I need to calculate the resultant rate (given the interest rate and escalation rate) for an annuity with an annual escalation.
The manual is extremely user unfriendly and I can not get it right. What I can do is to calculate the effective rate (if nominal rate and term is given). Can not however find a way to calculate resultant rate.
I also need an easy explanation to calculate the interest and capital components of a certain payment for amoritisation - the manual is also not very clear in this regard.
THank you so much

You can't use the calcuator for that you need to use the formula (1+interest/1+escalation) - 1. You then insert the follwoing on the calculator:
1) Number of compounding periods = shift P/YR,
2) Number of Years = Shift xP/YR
3) Number of Years = N
4) -1st cashflow = PMT
5) Resultant rate = I
6) 0 = FV
7) CPT PV
If this is the same manual that you have already ... then apologies!
