  • You see, I don’t trust such calculators.
  • You Know What They Say about Assuming… For instance, what rate of return does the calculator assume for your portfolio?
  • And what assumptions does the calculator make about future tax rates?

Common Mistakes to Avoid

It’s not that their math is wrong. (At least, not typically.) The problem is that their calculations are frequently based on shoddy assumptions and unknowable variables. Worth noting: or, perhaps, was the calculator programmed to assume that future returns will equal past returns (thereby ignoring the possibility that the U.S. economy won’t have the same explosive growth over the next century that it did over the last)?

Where the Real Savings Hide

Remember that if you’ve taken the time to educate yourself about investing, then you probably don’t require an online calculator. A straightforward excel spreadsheet will function at least as well. (And you get to pick your own assumptions!) Alternatively, if you haven’t taken the time to learn about investing, there’s no method for you to judge whether the assumptions that went into the calculator’s projections are reasonable.

In other words, there are two routes you can take: If you wish to be a do-it-yourself investor, super. But rather than rely on online calculators, you’ll require a deeper level of understanding if you wish to be successful.

A Closer Look at Online Retirement Calculators More

As a rule, if you don’t wish to go it alone, that’s fine too. But in that case, an online calculator isn’t what you require.

What you require is a qualified financial advisor. In my opinion, such calculators are only useful for young investors who are so far away from retirement that none of the relevant variables are known yet.
