Should You Put $100,000 in One Jumbo CD or Several CDs?

If you have $100,000 to invest in CDs, you can put it all into one jumbo CD or spread it across several traditional CDs. Jumbo CDs work much like traditional CDs, where you deposit money for a specified term in exchange for a fixed annual percentage yield (APY). Withdrawing money before the CD matures can trigger an early withdrawal penalty.

The main difference is the deposit requirement. Traditionally, $100,000 has been a common threshold for jumbo CDs, although requirements vary by financial institution.

Having more money to deposit doesn't automatically mean you'll get a better rate, though. Some of today's regular CDs compete with, and occasionally beat, jumbo CD rates. That means it's worth comparing both before locking up a six-figure sum, especially if putting the full $100,000 into one CD would leave you with less financial flexibility.

One jumbo CD vs. multiple CDs

At first glance, depositing $100,000 into one jumbo CD can seem simpler. You have one account, one interest rate and one maturity date to remember.

But dividing that same $100,000 among several CDs gives you more control over when portions of your money become available.

Here are some of the biggest differences to consider:

That last point can become especially important when interest rates are moving. At its October policy meeting, the Federal Reserve voted to hold interest rates steady, maintaining its benchmark target range of 3.75% to 4%. However, that doesn't mean CD rates will remain unchanged. Banks can still adjust their rates based on market conditions and expectations about future Fed decisions.

Suppose you deposit the entire $100,000 into a three-year fixed-rate jumbo CD. If CD rates rise significantly six months later, you're still earning your original rate unless your CD offers a bump-up feature or you're willing to pay an early withdrawal penalty.

With several CDs maturing at different times, you'll have more frequent opportunities to reconsider your strategy.

When multiple CDs could make more sense

Splitting $100,000 among several CDs could be the better choice when flexibility matters as much as yield.

For example, perhaps you're saving the money for a home purchase, retirement expenses or another large goal but aren't certain when you'll need it. Rather than locking the full $100,000 away until one maturity date, you might divide it into four $25,000 CDs.

You could also create a basic CD ladder by choosing different terms. One CD might mature in six months, another in 12 months and another later. As each CD matures, you can withdraw the money if you need it, or roll it into a new CD at the rates available at that time.

You don't necessarily need to sacrifice yield for that flexibility. As of early October, some standard CDs were paying rates comparable to jumbo products, such as 4.30% or more for several terms, while some jumbo products were also in the low-to-mid 4% range.

Multiple CDs can also reduce the consequences of needing your money unexpectedly. If the entire $100,000 is in one jumbo CD, your options for an early withdrawal will depend on that institution's rules and penalties. With four $25,000 CDs, for instance, you may be able to break only one CD and leave the remaining $75,000 untouched.

You can also spread your CDs among different banks or credit unions, which can become useful when you're managing balances near federal deposit insurance limits.

If you're deciding how to manage a large amount of cash alongside your other savings and investments, a financial adviser can help you weigh liquidity, returns and your longer-term goals.

When a jumbo CD could make more sense

There are still situations where putting the full $100,000 into one CD is the more attractive option.

The clearest is when the jumbo CD pays a meaningfully higher rate than comparable traditional CDs. Some jumbo CDs currently pay above 4%. If you've shopped around and that jumbo rate beats what you could earn with regular CDs of similar terms, the extra interest may justify giving up some flexibility.

A jumbo CD can also be appealing if you value simplicity. Instead of opening and managing four or five CDs, you can make one deposit and keep track of one maturity date.

Just make sure you're reasonably confident you won't need the money before then. Ideally, you should have enough liquid savings outside the CD to cover emergencies and near-term expenses. CDs generally aren't the best place for money you could need at a moment's notice because early withdrawal penalties may apply.

Don't overlook FDIC insurance

When you're dealing with $100,000 or more in cash, deposit insurance deserves a closer look. The standard Federal Deposit Insurance Corporation (FDIC) insurance amount is $250,000 per depositor, per insured bank, for each account ownership category.

That last part matters. The limit isn't simply $250,000 for every account you open. Say you already have $175,000 in a savings account at an FDIC-insured bank and then open a $100,000 CD there. If both are single accounts in your name, the FDIC generally adds those deposits together when determining your coverage. That would give you $275,000 in that ownership category, putting $25,000 above the standard insurance limit.

Opening four $25,000 CDs at the same bank instead of one $100,000 CD wouldn't solve the problem. The FDIC looks at the total amount held in the same ownership category at the same insured institution.

Deposits at federally insured credit unions receive similar protection through the National Credit Union Share Insurance Fund, which is administered by the National Credit Union Administration (NCUA). Single-owner accounts at federally insured credit unions are generally insured up to $250,000, with separate coverage available for certain other ownership categories.

If you have substantial cash savings, spreading CDs among different insured institutions can be one way to keep more of your deposits within applicable insurance limits.

What would $100,000 earn?

If you put $100,000 into a one-year CD earning 4.30% APY, you'd earn approximately:

$100,000 × 4.30% = $4,300

That would bring your balance to approximately $104,300 after one year, assuming you leave the principal and interest in the account for the full term.

Now consider splitting the same $100,000 among four one-year traditional CDs from different institutions, earning 4.35%, 4.30%, 4.30% and 4.25% APY.

Here's what $25,000 deposited at each rate would earn over one year:

• $25,000 at 4.35% = $1,087.50
• $25,000 at 4.30% = $1,075
• $25,000 at 4.30% = $1,075
• $25,000 at 4.25% = $1,062.50

Total interest: $4,300

In this example, the earnings are essentially identical: $4,300 either way.

Of course, rates change frequently, and these aren't necessarily the accounts or rates you'll find when you're ready to open a CD. But the example illustrates an important point: Qualifying for a jumbo CD doesn't necessarily mean you'll earn more money.

Even when the jumbo CD does pay more, consider how much the difference is actually worth. For example, a 0.10-percentage-point advantage on $100,000 amounts to roughly $100 in additional interest over one year.

You might decide that extra $100 is worth locking the entire balance into one CD for a year. Or you might prefer having portions of your money available at different times.

The rate matters, but so does what you're giving up to get it.

One jumbo CD or several CDs?

Don't choose a jumbo CD simply because you have enough money to qualify for one. The best option depends on the rates available, when you'll need the money and how much flexibility you want.

If a jumbo CD offers a meaningfully higher APY and you won't need the money before maturity, locking in one rate could make sense. But if rates are comparable, spreading your savings across several CDs with different maturity dates could give you more flexibility.
