CD stands for "certificate of deposit" — and is just that: a deposit account that earns interest. With a CD, you earn a fixed rate of interest for a fixed period. CDs come with different terms, such as six months, one year or five years, and you can't touch your funds in your CD for the entirety of that specified term length unless you pay an early withdrawal penalty fee plus possibly lose out on accrued interest.

A three-year CD, specifically, is a CD term of three years.

When you put your money in a CD, you earn a fixed interest rate for a fixed amount of time on the money you deposit when you open the account. Term lengths typically range from three months to five years. In this case, the CD term is three years.

While a CD is similar to a savings account, the traditional CD model differs in a couple of important ways:

1. You can only deposit money into the CD once at the beginning of the term. You can't make additional contributions over the CD's term. Sometimes, there's a minimum deposit requirement (usually $500 and up).
2. You can't access your money before your term ends or you'll get hit with an early withdrawal penalty. The penalty fees can vary depending on your bank and your CD's term length, but it's usually the interest earned or the interest you would have earned, over a certain number of days or months. Generally, the longer the CD term length, the costlier the withdrawal penalty.

Once the CD matures (when the term is over), savers can get their money back, in addition to the interest earned over time, or move the money into a new CD. CD terms usually auto-renew at the rate offered at maturity if you don't do anything.

One of the reasons you might want to consider a CD over ahigh-yield savings accountis because savings accounts havevariable APYs, and with a CD you lock in the rate the day you open the account. This can be good if you open an account when interest rates are high. It's not so great if you open an account after the Federal Reserve slashes interest rates.

CDs typically don't come with monthly fees and are federally insured so your money is protected, which makes them one of the safest savings vehicles.

Whenchoosing a CD, first focus on how long you want to keep your money locked up. A three-year CD will keep your funds locked up for three years.

Pick a CD based on your preferred length and the rate will follow. For example, if you want to save up for adown paymenton a home in a few years, consider a longer-term CD like a three- or five-year option and then look at what banks offer rate-wise for those specific CD terms. Shorter CD terms, such as three- to six-month CDs, are a good choice for beginners who want to save (and grow) their money for a short-term goal, such as a vacation.

When comparing CDs, make sure you're looking at CDs with the same term across different banks; this way, you're comparing "apples-to-apples." In this instance, you'd look at what banks and credit unions offer on their three-year, or 36-month, CDs.

Once you know the CD term you want, you can compare the different interest rates, as well as the minimum deposit requirements and any fees like early withdrawal penalties.

Some of the pros and cons of CDs are quite the same, and whether you see something as good or bad depends on other factors. We list what we think below.

Pros of CDs

• Fixed interest rates (a good thing when rates are high)
• Can't touch CD funds until the term is up (a good thing so you're not tempted to spend)
• DifferentCD typesallow you to have options, such asbump-up CDs(for raising your rate), no-penalty CDs (for easy withdrawals), add-on CDs (for making additional contributions), jumbo CDs (for large deposits) and IRA CDs (for retirement)

Cons of CDs

• Fixed interest rates (a bad thing when rates are low or if rates go up while you're in the middle of a CD term)
• Can't touch CD funds until the term is up (a bad thing if you need that money)
• Early withdrawal penalty fees may apply
• Can generally only deposit money into a CD once at the beginning of the term and can't make additional contributions
• Usually a minimum deposit requirement, typically $500 and up

To determine the best three-year CDs, CNBC Select compared dozens of options offered by online banks and credit unions. We found that many of the best three-year CD rates are offered by credit unions, but we only considered those credit unions that had membership eligibility open to anyone.

When ranking the top three-year CDs, we prioritized the ones offering the highest APYs. We then compared three-year CDs by looking at their minimum deposit requirements, penalties for early withdrawals, ease of use and industry rankings. We ranked our top picks by best for high APY, best from an online bank, best for low minimum deposit, best for a large deposit and best from a credit union.

All of the CDs included on this list are FDIC- or NCUA-insured up to $250,000 per person. The rates and fee structures banks advertise for their CD accounts are not guaranteed forever. They are subject to change without notice and they often fluctuate in accordance with the Fed rate. If you open a CD account, however, you're often locked into that APY offered at account opening for the entire term length.

Your earnings depend on the CD term length, the amount you deposit, the APY offered when you opened the account and any associated fees. Generally, a larger deposit and a higher interest rate will earn you the most money. Any early withdrawals may result in penalty fees that lower your principal balance/earnings.

To open a CD account for the first time at a bank, most banks and institutions require a deposit of new money, meaning you can't transfer money you already had in an account at that bank.
