They all give me wildly different numbers.

I would recommend learning how one of these calculators works and then you can create and customize your own retirement calculator. You want your result to be realistic, so you should consider your current and future savings as well as what you think your retirement needs (financially) will be.

Post the calculators and your inputs, then lets discuss why they are different.
