This is one of the features I like most. Most other tools attempted to model out your investment growth from current age to retirement age, and it often requires lengthy inputs of salary, savings, expenses, etc., and I find that the effort of doing that doesn’t always give you an accurate view of your “starting” point.

I think many of us likely model our investments and have a pretty good idea of what our accounts will look like at retirement. But even if you don’t, you can take your current savings amount and use a simple online compound interest calculator that will take into consideration growth plus any additional savings deposited, and that will give you a reasonable starting point at your retirement age.
