Financial TipsInvestmentsSaving MoneySavingsYou may be familiar with certificates of deposit (CDs), but bump-up CDs are unique. Here’s how they work and what to understand before considering one.

A certificate of deposit (CD) is a type of investment product that pays you a relatively high interest rate as long as you commit to keeping your money in the CD for a set period of time, known as the term. Throughout the term, the CD grows, earns interest, and “matures.” At the final maturity date, you can withdraw your funds (including accrued interest) or roll it over into a new CD. If you take out your money before it matures, you’ll usually have to pay an early withdrawal penalty.
It seems simple enough, but there are also different types of CDs you need to know about before choosing to invest in one. For example, you could get a regular CD, a high-yield jumbo CD, a step-up CD, or a bump-up CD (also called a jump-up CD, trade-up CD, or raise-your-rate CD). This last type stands out because it lets you respond to rising interest rates.
Bump-up CDs let you “bump up” your interest rate, usually once during the term. You’re typically not limited on when you make that bump, but you’ll want to pull the trigger when you think interest rates are at the peak … kind of like playing blackjack and deciding whether to hit or stand.
If your CD requires a certain minimum deposit — which most of them do — you’ll have to put in at least that much money. The minimum deposit required to open a bump-up CD can vary from bank to bank, but you’ll typically need at least $500 to $1,000 to start.
If we’re talking about a jumbo bump-up CD, the minimum deposit is much higher. Jumbo bump-up CDs usually require $50,000 to $100,000 for your initial investment — and the more you deposit, the more you’ll make.
Most CDs provide a higher yield than a standard savings account. In fact, your CD’s annual percentage yield (APY), or the interest rate you earn, is typically among the highest available when you open it.
The problem is that interest rates change, and CDs usually require you to lock in your money for months or years. If the interest rate goes up during your term, you normally don’t get the higher rate. But a bump-up CD solves that dilemma by allowing you to opt for a rate increase if the offered APY goes up.
It’s nice to have the flexibility to increase your interest rate. However, this option comes with restrictions, so you have to be strategic in your timing. Generally speaking, you only get one chance to bump up your rate — or sometimes two, on a longer term.
When you’re ready to take an increase, you can usually just select the bump-up option online through your CD account. If that feature isn’t offered, you might need to call the bank.
When your CD matures at the end of your term, you typically have a few options.
The numbers and details might change, but the structure is pretty consistent. Here’s how a typical bump-up CD could look.
Let’s say you get a 24-month bump-up CD with an option to increase your rate one time only.
But what if interest rates go up further after that first increase?
It’s like the internet meme that says, “You can only pick one. Choose wisely.” This is a bit of a guessing game, which requires studying the market and predicting future conditions to optimally pull it off. But if you don’t want to be stuck with one rate for several years, it might be the perfect choice.
Bump-up CDs appeal to a range of people looking for a lower-risk investment option.
If you have a low risk tolerance, CDs are a good choice. They’re usually FDIC-insured and work on fixed rates, so there are not a lot of surprises. Bump-up CDs provide the added benefit of being able to increase your rate while still enjoying the peace of mind that comes from knowing your money is safe.
Besides being predictable, CDs have a preset term that makes them a good choice for continuing to build savings over several years. With a bump-up CD, you get the best of both worlds — long-term money growth as well as a future rate increase to reach your savings goals that much faster.
If you typically invest in high-risk options like stocks or bonds, it’s good to have some lower-risk options to balance out your investment portfolio. High-risk volatility often translates to greater returns, but it can also mean bigger losses. Bump-up CDs provide some needed stability while keeping the excitement of choosing when to pull the trigger.
If you’re pretty sure interest rates are going up instead of down, a bump-up CD is a great fit. While other CDs let you hedge against falling interest rates, bump-up CDs let you capitalize on rising rates.
Most standard CDs don’t give you the opportunity to change your interest rate at all. Bump-up CDs are one of the few exceptions. But as for how many times you can use your rate bump, it depends on the terms of the CD.
Typically, bump-up CDs let you bump up your rate one time, and only one time, during your term. So if that’s the type of bump-up CD you have, you won’t be able to increase your interest rate more than once.
However, it’s possible to find a bump-up CD that allows more than one rate bump. The most common variant would let you increase your rate twice during the term, but those CDs usually also have a longer term — like four years or more.
The obvious advantage to bump-up CDs is the ability to raise your rate during the term, but there are other benefits too.
Even though you get to bump up your rate during the term, you’ll often start with a lower rate than fixed-rate high-yield CDs. There are a few other drawbacks as well.
CDs and similar savings products come in several varieties, each with its own pros and cons.
If you’d like to open a bump-up CD account, here’s the step-by-step process.
Once you’ve set up and funded your account, you’ll start to earn interest at the initial rate. But with bump-up CDs, it’s important to monitor the economy. Unlike other CDs, this isn’t a set-it-and-forget-it type of offering.
Bump-up CDs offer advantages over other types of CDs, but there are disadvantages as well. If you’d like to explore whether it’s right for you, take a look at Credit One Bank’s Bump-Up Jumbo CD.
