Frequently Asked Questions
What is a money market account?
A money market account is a type of savings account that typically offers higher interest rates than regular savings accounts while maintaining FDIC insurance. Money market accounts invest in short-term government securities and certificates of deposit, passing the earnings on to you.
How does compounding frequency affect returns?
More frequent compounding means higher returns. Daily compounding earns slightly more than monthly, which earns more than quarterly or annual compounding. The difference can be significant over long time periods or with large balances.
Are money market accounts safe?
Yes, money market accounts at banks are FDIC insured up to $250,000 per depositor, per institution. Credit union money market accounts have similar NCUA insurance. They're considered very safe, low-risk investments, though returns may not always outpace inflation.
Should I make monthly contributions?
Regular monthly contributions dramatically accelerate wealth building through compound interest. Even small monthly additions make a significant difference over time. Our calculator shows you exactly how much extra you'll earn with consistent contributions.
