Planning for your retirement ahead of time is something that you should always be doing. A pre retirement planner is something that you can find in the Excel program. If you set up the program to run these figures for you, you are very likely going to find that you are able to calculate the amount that you need to save for your retirement pretty well.
You will have those figures ready to go for whenever you are ready to move on towards actually saving the kind of money that you need to save for your retirement goals. That is the dream of everyone.
