How Does a 401(k) Calculator Work?
Since you now know the various kinds of 401(k) calculators, you may be curious about how they work. Let's demystify.
Understanding Your Contributions
The calculator will prompt you to enter your monthly contribution. This is how much you're contributing to your 401(k) each month. The higher the amount you contribute, the higher the amount you'll have at retirement.
How Employers Match Contributions
Most employers will match your 401(k) contribution up to a level. This is, in effect, free money, and the calculator will account for that also.
Investment Growth and Compound Interest
One of the most important elements of 401(k) growth is the return on your investments. The calculator will calculate the return on your 401(k) each year and compound interest, which is where the interest you've earned gets added to your principal so you can earn interest on your interest.
The Impact of Fees on Your 401(k)
Fees can nibble away at your returns, so it's a good idea to factor them in. A quality calculator will allow you to include such things as mutual fund fees and account management fees to determine their impact on your 401(k) balance.
