Is there a simple rule to follow for when to use s^Dx and when to use Sx-1.Dx whenever calculating Past/Future Service benefit questions using commutation functions?
when you are told that the last salary increase occurred in the year prior to valuation at age x you use Sx-1. You can watch examples of derivation of the pension formulae from this video '' The entire playlist is golden it has helped me understand the derivation of pension formulae
Hey Harashima, Thanks for clearing that up for me. And thanks for the video link - from what I've watched so far it is very helpful.
