Two Ways to Earn More — With Different Trade-offs
When you want to earn more interest than a regular savings account offers — without taking on investment risk — money market accounts and certificates of deposit (CDs) are two of the most popular options. Both are safe, FDIC-insured products. But they work quite differently, and the right choice depends entirely on what you need from your money.
What Is a Money Market Account?
A money market account (MMA) is a type of deposit account that typically offers a higher APY than a standard savings account, along with some features of a checking account. Many MMAs come with a debit card or the ability to write a limited number of checks per month.
Key characteristics:
- Variable interest rate (can go up or down)
- Funds are accessible — no lock-in period
- Often requires a higher minimum balance to earn top rates
- FDIC-insured up to $250,000
What Is a Certificate of Deposit (CD)?
A CD is a time-deposit account. You agree to leave a specific amount of money with the bank for a fixed term — anywhere from a few months to several years. In exchange, the bank offers a guaranteed, fixed interest rate for the entire term.
Key characteristics:
- Fixed interest rate — locked in for the term
- Early withdrawal typically incurs a penalty
- Terms range from 1 month to 5+ years
- FDIC-insured up to $250,000
Side-by-Side Comparison
| Feature | Money Market Account | Certificate of Deposit |
|---|---|---|
| Interest Rate | Variable | Fixed for the term |
| Access to Funds | Flexible, anytime | Locked until maturity |
| Early Withdrawal | No penalty | Penalty applies |
| Minimum Deposit | Often higher ($1,000+) | Varies ($0–$1,000+) |
| Best For | Accessible savings | Set-and-forget savings |
When to Choose a Money Market Account
- You want better rates and the flexibility to access your money
- You're building or maintaining an emergency fund
- You want a debit card or check-writing ability with your savings
- You expect interest rates to rise (variable rates can benefit you)
When to Choose a CD
- You have a specific savings goal with a known timeline (e.g., a home purchase in 18 months)
- You want to lock in a high rate before rates potentially drop
- You want guaranteed, predictable growth
- You're comfortable not touching the money until maturity
The CD Ladder Strategy
One smart approach is to combine multiple CDs with different maturity dates — known as a CD ladder. For example, instead of putting $10,000 in a single 3-year CD, you split it across 1-year, 2-year, and 3-year CDs. As each matures, you reinvest. This gives you regular access to portions of your money while still earning competitive rates.
The Bottom Line
If flexibility matters, a money market account is the stronger choice. If you want to lock in a rate and maximize predictable earnings on money you won't need soon, a CD wins. Many savers use both strategically — a money market for their accessible reserves and CDs for longer-term goals.
