What Is a High Yield Savings Account?

As the name implies, a high yield savings account is a type of savings account that tends to offer better rates than a traditional savings account. Depending on where you bank, high yield savings account rates range from 2% to 5% APY, compared to a conventional savings account, which is closer to 0.40%.

High yield savings accounts tend to be an ideal option for people who don’t need as frequent access to their funds and are more content to watch their money grow.

Pros of a High Yield Savings Account

Here’s a closer look at some of the key advantages of high yield savings accounts:

  • As discussed, arguably the biggest advantage of a high yield savings account is that they offer better rates compared to conventional savings account options, allowing savers to grow their money faster.
  • While high yield savings accounts don’t have direct access to debit cards or check-writing, it’s easy to conduct mobile or online transfers of funds.
  • When the market is strong, you’ll earn more with your high yield savings account. Such accounts come with variable rates that ebb and flow with the current market.

Cons of a High Yield Savings Account

Despite some notable advantages, high yield savings accounts do offer some significant drawbacks. These include:

  • Annual Percentage Yield (APY) is variable. While rates can climb when the market is strong, they can just as easily dip in a downturn.
  • There’s limited transaction flexibility compared to other types of savings options. While transfers can be made online or in person at your local branch, you won’t have check-writing or debit card access.
  • Many institutions offer promotional rates to entice savers, but there can be a lot of fine print. For instance, the best interest rates may require a certain balance or only be available with direct deposit. The institution may also be unfamiliar with the needs of the local community.

What Is a Money Market Account?

Not to be confused with a money market mutual fund, which is an investment product that is not federally insured, money market accounts are savings options that also offer check-writing and debit capabilities, permitting more flexible access for account holders. Money market accounts are deposit accounts that pay tiered interest based on your balance (i.e., the more you save, the more you’ll earn).

Pros of a Money Market Account

Some of the key advantages of a money market account include:

  • High balances can outpace flat-rate high yield savings accounts when it comes to returns, offering an ideal savings option for savers who have access to larger sums of money.
  • Money market accounts combine better rates with flexibility, allowing savers to plan for larger short and long-term expenses.
  • Money market accounts are NCUA insured up to $250,000 per share owner, which is the same as Federal Deposit Insurance Corporation (FDIC) bank coverage.

Cons of a Money Market Account

Despite these benefits, money market accounts aren’t ideal for all types of savers. Here’s a look at some of the drawbacks:

  • There are often higher minimum balance requirements, and some institutions may charge a monthly fee if the balance dips below them. At Island Federal, members can open a Money Market Plus account with just a $2,500 minimum deposit, but members need at least $50,000 to open a Money Market Gold account.
  • Withdrawal limits may only apply to certain types of transactions, similar to those of a savings account, which can affect how you use these bank accounts alongside a checking account.
  • Lower balances can often underperform compared to a high yield savings account.

The bottom line is that high yield savings accounts are likely to be the better option if you have lower balances that you’re looking to grow. However, money market accounts are ideal for growing higher balances while maintaining flexible access to your funds.

Key Similarities Between Money Market and High Yield Savings Accounts

While money market accounts and high yield savings accounts have their differences, they also have a lot in common. Here’s a look at some of the key similarities between these types of accounts:

  • They’re both federally insured up to $250,000 per share owner. Money market accounts at credit unions are protected by the NCUA and high yield savings accounts at banks are protected by the FDIC.
  • Both types of accounts are designed primarily for saving rather than spending, though each has its own ways of transferring and accessing funds.
  • Both accounts can earn significantly more than a standard savings account, offering a faster way to grow savings.
  • It’s easy to open either type of account, as each can be opened either online or in person at a local branch.

Key Differences That Matter Most

Some of the key differences between money market accounts and high yield savings accounts that you’ll want to consider include:

  • APY structure: APY structure: Money market accounts have a tiered APY structure, so the more you save or have in the account, the better your return. As your balance grows and moves into higher tiers, your APY increases, meaning larger balances earn more. Conversely, high yield savings accounts have a flat APY that varies based on market conditions. With a flat-rate account, every dollar earns the same rate regardless of balance, while a tiered money market bumps your rate up as you cross into a higher balance tier.

  • Account access: If flexibility is important to you, money market accounts offer more of this than high yield savings accounts do. Most high yield savings accounts only allow 6 transactions per month, all of which are limited to balance transfers. Money market accounts offer check-writing and debit capabilities.
  • Minimums and fees: At Island Federal, members must have a minimum $2,500 for a Money Market Gold account and $50,000 for a Money Market Plus account. Balances below those minimums could be subject to penalties. High yield savings accounts typically don’t have a minimum balance and aren’t subject to monthly fees.

Which Account Is Right for You? A Decision Framework

High yield savings or money market account? Wondering which one is best for you? It really depends on your situation and your savings goals.

The biggest factor is your savings portfolio. If you have a large savings balance or want more flexible access to your money, a money market account is likely the way to go. However, if you’re looking to build an emergency fund or earn higher yields on a smaller savings balance, a high yield account is likely the better option.

Say that you’re a Suffolk County family that wants to save for a down payment on a new home in a few years. They’d likely benefit from a high yield savings account to help supplement any existing savings. A different scenario might be a Nassau retiree managing a larger nest egg, who would likely benefit more from a money market account to take advantage of higher rates on larger balances while still having convenient access to funds.

Think of it like this: If you’re trying to build an emergency fund or boost a smaller savings amount for a future purchase, a high yield savings account is probably the better option. But if you have a large sum of money, you’re likely to benefit more from a money market account. In some cases, it may even make sense to pair an Island Federal money market account with a high yield savings account.

Frequently Asked Questions

Is a money market account better than a high yield savings account?

It depends on your personal financial situation and your specific savings needs. A money market account is ideal for you if you have a large savings sum and need access to funds, as it offers debit and check-writing capabilities. A high yield savings account tends to be preferred by savers who don’t need to access the funds and have lower amounts.

Can you lose money in a money market account at a credit union?

You cannot lose your principal deposit as part of a money market account if the market takes a downturn. All money market accounts are insured by the NCUA up to $250,000 per member. However, your money market account balance can decrease should it fall below the minimum requirement, and you’re subject to penalties, or if rates fail to outpace inflation.

How much money should I keep in a high yield savings account?

While this largely depends on your personal situation, it’s best practice to keep anywhere from three to six months’ worth of living expenses in a high yield savings account as an emergency fund. This can create a nice safety net while still having a large enough balance to generate a significant return. You may elect to add more money into the account to assist with any short-term goals over the next 1-3 years, like a car down payment, wedding or vacation.

Does Island Federal offer a high yield savings account?

Island Federal offers savings accounts to meet the needs of all members. Offerings include standard savings accounts, IRA savings accounts and special youth savings accounts for members 16 and younger. Contact Island Federal today to learn more about our savings account options and which one is best for you.

How often do high yield savings rates change?

High yield savings account rates can change at any time without any advance notice. While it’s unlikely they change daily, changes are common every few weeks to a few months, usually in response to the Federal Reserve’s rate updates.

Can I pair an Island Federal money market account with my regular savings account?

Yes, using a money market account alongside a regular savings account is a great way to manage your money. It’s best practice to put a large portion of your money into a money market account, while keeping any remaining money in an emergency savings account. Consider using the savings account for emergency funds and short-term goals and the money market account for longer-term growth.

What is the difference between a money market account and a money market fund?

A money market fund is an investment product whose value fluctuates with market rates. These funds are also not federally insured. Money market accounts function more like conventional deposit accounts, with check-writing and debit card access.
