Frequently Asked Questions

Should I contribute enough to get the full employer match?

Yes — always capture the full employer match before anything else. An employer match of 50% up to 6% of salary is an immediate 50% return on investment. No other investment offers guaranteed returns like this. Not capturing the full match is leaving part of your compensation on the table.

What is the 401(k) contribution limit?

For 2024, you can contribute up to $23,000 to a 401(k) if you're under 50. If you're 50 or older, the catch-up contribution limit allows an additional $7,500, for a total of $30,500. These limits apply to your contributions only — employer matches don't count toward your personal limit.

What is compound interest?

Compound interest is interest earned on both the original principal and previously accumulated interest. It makes your money grow exponentially over time, which is why starting early is so powerful.

What is a realistic rate of return?

The stock market has historically returned about 10% annually before inflation (7% after). Bonds return 3-5%. A balanced portfolio might expect 6-8% long-term.
