Certificates of deposit, or CDs, are a simple way to grow your savings without taking on market risk. When you open a CD, you agree to leave your money with a bank or credit union for a set period of time in exchange for a fixed interest rate. Their predictable structure makes CDs appealing to investors and savers who want stability. Choosing the best strategy for investing in CDs can let you reach your financial goals quickly while earning interest income on your money.

How to Start Investing in CDs
One of the most important variables to investing in CDs is deciding your investment time horizon. You need to decide how long you can and want to keep your money locked away, earning interest. Most CDs have terms ranging from three months to five years. Next, you need to compare interest rates across banks and credit unions. While the national average for savings account rates hovers around 0.39%, some CDs offer yields much higher than that, depending on the term and current market conditions.[1]

You should also check whether your CD is insured. Most CDs are insured by the FDIC, which protects up to $250,000 per depositor, per institution, adding an important layer of security to your investment.[2] Once you understand your timeline and risk tolerance, you can choose one of the smart strategies for investing in CDs that fits your investing goals.
Strategy #1: Create a CD Ladder
A CD ladder involves spreading your investment across multiple CDs with different maturity dates. This approach gives you regular access to funds while still earning competitive interest rates.
Example of a CD Ladder
Let’s say you have $10,000 to invest in CDs. To create a CD ladder, you could choose to invest $2,000 in five different CDs with terms of 1, 2, 3, 4, and 5 years. Each year, as one CD matures, you reinvest your principal and interest income into the next 5-year term CD, creating a continuous ladder of CDs ranging from one to five years. This allows you to capture prevailing market interest rates, regardless of whether they are decreasing or increasing.

When a CD Ladder Is Great
Fixed-income investors flock to the idea of building a CD ladder. A CD ladder works well if you want to generate a steady stream of known interest income payments or want the flexibility of how to deploy your expiring CDs. It is particularly appealing when interest rates are rising, since you can reinvest matured CDs at higher yields, continuously capturing higher interest income.

Why It Pays to Create a CD Ladder
Laddering reduces the risk of locking all your investment funds into a low-rate CD and not having access to your money to invest in higher-yielding assets. It also gives you a constant stream of liquidity without sacrificing long-term returns.

Strategy #2: Create a CD Barbell
A CD barbell strategy splits your investment between short-term and long-term CDs, avoiding medium-term options. This allows you to benefit from higher long-term rates while keeping some funds accessible.

Example of a CD Barbell
If you had $10,000 to invest in CDs and wanted to create a CD barbell, you would allocate $5,000 to a six-month CD and $5,000 to a five-year CD. When the short-term CD matures, you keep reinvesting into six-month CDs based on interest rate trends.
When Is Building a CD Barbell Smart
A barbell strategy is highly useful when the interest rate environment is very uncertain. For example, if the broader economy is going through a correction, then a CD barbell lets you earn interest income while maintaining flexibility by allowing you to capture higher yields while still having the adaptability to respond to changing conditions.
Why It Pays to Create a CD Barbell
The CD barbell strategy is ideal for investors who feel like they need to balance investment risk and reward. You can earn higher returns from long-term CDs while still keeping some liquidity for emergencies or new investment opportunities that might yield higher returns.

Strategy #3: Create a CD Bullet
A CD bullet strategy focuses on a single maturity date. This strategy focuses on investing in multiple CDs that all mature around the same time, usually aligned with a financial goal – like saving for an emergency fund, wedding, or down payment for a house.
Example of a CD Bullet
Imagine you are a first-time homebuyer saving for a down payment, which you think will take you three years. As part of your savings, you might invest equal amounts in CDs with terms that all mature near that target date. This ensures your funds are available when you need them.
When a CD Bullet Makes Sense
This strategy works best for goal-based saving. The CD bullet is ideal for when you have known or planned expenses such as tuition, a home purchase, or a major life event, like a wedding.
Why It Pays to Create a CD Bullet
A CD bullet strategy keeps your savings focused and disciplined. By aligning maturity dates with your capital requirement and timelines, you can reduce the temptation to withdraw funds early and face penalties. This will keep you on track for your savings goals.
