The pros and cons of using retirement planning software to help you figure out your needs

Plenty of people approaching retirement want to run their own numbers before sitting down with a professional, and a growing set of planning tools promises to help. This piece takes one such program out for a test drive and weighs what software like this does well against where it falls short. The honest takeaway is that a calculator can be a genuinely useful starting point for picturing your future income and spending, but it still rests on the assumptions you feed it, and it cannot account for every wrinkle of a real life. It is a worthwhile read for the do-it-yourself planner who wants to understand what these tools can and cannot tell you, and who would rather go in with realistic expectations than treat any single projection as the final word on whether their retirement adds up.
