Using FIRECalc tool to determine FI status

One of the nice free tools that are available on the internet is the FIRECalc tool (see list to right). This tool allows you to put in a variety of data and variables, and try out different scenarios to see if you meet your goal, based on historical performance. The tool uses stock market history and your portfolio choices to try and predict how well you should do for a certain period of the future.

While not perfect (nothing is) it is a good first step towards exploring your goals and how close you are to FI. I will be discussing other tools in the future, but this is an excellent first start.

When you open the FIRECalc page, it provides a description of the model, what it does, how to navigate, etc. It is here where you start, putting in your annual spending, your portfolio value (401K, IRA, 403b, etc.), and the number of years you expect to be “retired.” The program will use this as a basis for determining your success.

The next tab is where you put in “other income” during retirement, above and beyond your retirement assets. Here is where you would put in your Social Security or pension benefits.

The next tab is the “not retired” tab, where you can put in how many additional years you intend to work before acting on your early retirement plan. It also provides a place to show the additional money you intend to invest during this time.

The spending models tab allows you to input the plan for inflation, how your spending power will go (i.e. adjusted for inflation, high expenses to start and less as you grow older, using a percentage of your portfolio, etc.) This lets you look at a variety of options on how you plan to spend, to see if you can achieve your goals.

The next tab is for your portfolio. Here you can use a consistent historical average, or provide your own asset allocation. Again, this allows you to look at the range of options and “play” with them to see how it would affect the result.

There is an optional tab for portfolio changes, lump sum additions to your portfolio (like inheritance, home sale, etc.)

The last tab shows a variety of investigation options you can get from the result, including changes to your allocation, delaying retirement, and spending levels. Just another set of options to play with to further analyze and refine your plan.

Once you are done entering all your information and options, just click on the “submit” button at the bottom to get the results. It will determine, based on the period it studies, how often your plan will succeed or fail, and will provide the lowest, highest, and average portfolio balances for you at the end.It should give you a “big picture” view of how your plan worked out. Now you can go “tweak” some of the entries to see how you might do.

Good luck, and I hope it provides you with some good news!
