Deciding where to stick your savings is tricky.
Savings accounts and money market accounts are highly liquid but usually offer a low rate of return.
Long-term CDs usually offer better rates. But unless you’re willing to pay a premium for withdrawing your funds early, they’ll be locked in for years.
An 18-month CD offers the best of both worlds: a higher yield than a standard savings account and a low level of commitment.

Bankrate regularly surveys around 70 widely available financial institutions, made up of the biggest banks and credit unions, as well as a number of popular online banks.
To find the best CDs, our editorial team analyzes various factors, such as: annual percentage yield (APY), the minimum needed to earn that APY (or to open the CD) and whether or not it is broadly available. All of the accounts on this page are insured by Federal Deposit Insurance Corp. (FDIC) banks or by the National Credit Union Share Insurance Fund (NCUA) at National Credit Union Administration (NCUA) credit unions.
When selecting the best CD for you, consider the purpose of the money and when you’ll need access to these funds to help you avoid early withdrawal penalties.
How does an 18-month CD work?
With a CD, you agree to leave your money in the account for a set period of time — in this case, 18 months. In return for your commitment to leave the money alone, you receive a higher yield from your bank or financial institution.
With an 18-month CD, your interest rate is locked in, so you don’t have to worry about your bank potentially lowering the rate on your account.
An 18-month CD can be ideal for setting aside money for short-term goals, such as going on vacation or saving for a car down payment. You can also use an 18-month CD to build a CD ladder.
Don’t assume that the best 18-month CD rates are found at your current bank. Instead, compare CDs online.

Coronavirus and Your Money
The COVID-19 pandemic is deepening financial hardships for millions of Americans.
While CD rates are not likely to rise in this environment, their stability can offer some comfort to those who still have extra cash on hand. The rate on a CD stays the same during the deposit term and the account holder knows exactly when that term will end. With their locked-in interest rates, CDs are also a great choice to avoid the stock market’s ups and downs.
Can you lose money in a CD?
For the most part, as long as your money is deposited at an insured institution, you won’t lose money. Double-check that your CD is in an FDIC-insured bank or in a National Credit Union Administration (NCUA) credit union. The NCUA manages and operates the National Credit Union Share Insurance Fund (NCUSIF). These entities insure bank deposits against failure, protecting your money for typically up to $250,000.
Because CDs are cash deposit accounts, your principal, or initial deposit amount, is safe. You don’t have to worry about losing money to market crashes, either. However, your account could lose value due to inflation. Depending on the situation, the yield you earn in a CD might not keep up with inflation, resulting in a loss of spending power.
Also, if you withdraw money out of a CD before it matures, you will likely have to pay a fee, such as a few months’ worth of interest.
If you’re looking to protect your principal, though, your money is safe in a CD if you’re within FDIC insurance limits and guidelines.
18-month CD vs. other short-term investments
An 18-month CD is a relatively short-term investment. While your money is locked up for a year and a half, you’ll have access to it — plus interest — when the term expires. When comparing your savings options, it’s important to take into account liquidity as well as yield.
18-month CD vs. 12-month CD
When you get a 12-month CD, you’re likely to see a smaller yield than an 18-month CD. Because a 12-month CD doesn’t lock your money away as long, the yields are often a little lower.
However, with the shorter-term CD, you can access your money six months earlier. So, if you think you want penalty-free access to your money before an 18-month CD matures, it makes sense to take the lower yield in return for slightly better liquidity.
Consider savings accounts with higher yields
You can find high-yield savings accounts that pay rates similar to top-yielding shorter-term CDs, like those with terms of 12-18 months.
However, with a savings account, you have more immediate access to the money, and you typically won’t be penalized for making withdrawals. If you have short-term goals you’re saving for, or if you want a more accessible emergency fund, a savings account can be a smart choice.
Consider money market accounts with high yield
Another possibility, especially if you want check-writing privileges, is a money market account. There are money market accounts with much higher yields than traditional savings accounts, as well as quick, easy access to your money when you need it.
With a top-yielding money market account, you might find a similar yield compared with top-yielding 18-month CDs. However, if you’re looking for penalty-free liquidity and accessibility, a money market account can be a good choice.
When you choose money market or savings accounts, you have to be aware of the fact that your rate could drop at any time. With a CD, you lock in a rate, so you don’t have to worry about falling rates. The flip side, though, is that rates could go up, and if your money is in a CD, you can’t take advantage of the higher rate until after the term expires.
Short vs. long-term CDs
When considering an 18-month CD, compare it to longer-term accounts. There are CDs that will lock up your money for two years or more, but they also pay higher yields.
If you’re willing to avoid touching your money for a longer period of time, you could take advantage of yields that provide you with much better returns than an 18-month CD. In fact, a 5-year CD often has better yields, and your money remains safe.
There are even 10-year CDs, sometimes designed to be held in an IRA, that can provide you with safe yields.
Before making a decision about what type of CD you want, consider your financial needs and situation. Think about when you might need to access the money and weigh it against the yield you receive.
Before taking the plunge
An 18-month CD is a low-risk investment. But before you purchase one, it’s important to know what you’re getting yourself into.
Ask if you’ll have to maintain a certain balance to earn the APY. While you’re at it, find out how often you’ll receive the interest you’re earning from your bank or credit union. That way, it’ll be easier to hit your savings target or another financial goal.
