Agree with cvmom. There are some good retirement calculators out there… some are pretty in depth about *all* sources of income (including possible rental income, pensions, etc.) Others are very superficial.
I obsess about retirement. Seriously obsess. Constantly running “what if” calculations. My favorite tool is one built into quicken. But you have to buy quicken to get it.
Also to consider… you talk about your net worth, all in. I assume that includes equity in your home. Do you plan to sell the home at retirement, or still live there? Some people plan on downsizing, or selling and renting. Others plan on retiring in place. You need to adjust accordingly. Personally, I plan on retiring where I am, so I do *not* include my home equity in my retirement calculations. I need the shelter more than the equity.
