Certificates of deposit often pay more than savings accounts, but they come with a catch: your money is locked up until the term ends. A CD ladder is a straightforward way to get CD-level rates while keeping regular access to part of your cash.
CD basics
A CD is a deposit account where you agree to leave money for a set term — say, 6 months to 5 years — in exchange for a fixed rate. If you withdraw early, you’ll usually pay a penalty, often a few months of interest. CDs at FDIC-insured banks and NCUA-insured credit unions are federally insured; see how FDIC insurance works.
How a ladder works
Instead of putting all your money in one CD, you split it across several with different maturity dates. Here’s a classic five-rung ladder with $10,000:
- $2,000 in a 1-year CD
- $2,000 in a 2-year CD
- $2,000 in a 3-year CD
- $2,000 in a 4-year CD
- $2,000 in a 5-year CD
After one year, the 1-year CD matures. You can use the money or reinvest it in a new 5-year CD. Repeat each year. Eventually, all your money is in 5-year CDs (usually the highest rates), but one matures every single year.
Shorter ladders for shorter goals
You don’t need a five-year ladder. If you want access more often, try a 3-, 6-, 9-, and 12-month ladder, so something matures every quarter. This can work for money you’re saving toward a goal in a year or two, like a car or a down payment.
Why use a ladder?
- Regular liquidity. Part of your money becomes available on a schedule.
- Rate averaging. If rates rise, maturing rungs can be reinvested at higher rates. If they fall, your longer CDs keep earning the old, higher rate.
- No guessing. You don’t have to predict where rates are headed.
- Guaranteed returns. Unlike stocks, the rate is set when you open the CD.
The downsides
- Inflation risk. A fixed rate can lose ground to inflation over long terms.
- Penalties if you need money from a rung before it matures.
- More to manage. Several CDs, several maturity dates.
- Auto-renewal traps. Many CDs automatically roll into a new CD at whatever the bank’s current rate is. Set calendar reminders for the grace period after each maturity.
Variations worth knowing
- No-penalty CDs: lower rates, but you can withdraw early without a penalty.
- Brokered CDs: bought through a brokerage, often from many banks. They can be sold before maturity on a secondary market, but the price may be lower than you paid if rates have risen.
- Treasury ladders: the same idea using Treasury bills or notes from TreasuryDirect. Interest is exempt from state and local income tax, which matters in high-tax states.
Where a ladder fits
Don’t put your entire emergency fund into CDs — keep at least a month or two of expenses in an instantly accessible account. A ladder works well for the remainder of a large emergency fund, savings for a goal a few years away, or the cash portion of a retiree’s portfolio. For long-term growth over decades, investing in index funds generally makes more sense.
Comparing CD rates
Compare the APY, not just the interest rate — we explain why in APY vs. APR. Online banks and credit unions often pay more than big branch banks. Also look at the early withdrawal penalty and the minimum deposit.
Bottom line
A CD ladder gives you better rates than a typical savings account without locking all your money away at once. It’s simple, insured, and low-stress — a solid option for cash you won’t need right away but want to keep safe.
