CALCULATION OF RESULTANT RATE ON TEXUS CALCULATOR

Question

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
