How much money should you have in a high-yield savings account?

High-yield savings accounts are generally recommended as a vehicle to stash your savings, including your emergency fund.

And while some checking accounts, like the Ally Bank Spending Account or the Capital One 360 Checking® do offer slightly higher interest rates compared to traditional checking accounts, their interest rates are still lower than what high-yield savings accounts offer.

"Like many Americans, you may default to leaving extra funds in a traditional checking or savings account," says Dan Stampf, a CFP® and Vice President of Advisory Solutions for Empower. "Maybe you haven't decided how to allocate it to investment accounts. Perhaps you're stowing away money for a rainy day or emergency fund. Or you could be building up savings for a short-term goal like funding a wedding or a vacation."

Regardless of your savings account's purpose, knowing just how much to keep in this account is important. Below, CNBC Select covers what savers should expect.

Of course, you do want to make sure you're investing — and not only saving — so you can reach long-term goals like retirement. So you do have to draw a line between how much you should invest versus keep in a savings account.

"Everyone's financial situation is different and the amount of cash you have on hand will depend on your life stage and savings goals," Stampf says. "As a general rule, consider aiming to have six to 12 months worth of liquid cash or cash alternatives, so you can withdraw from those if needed without touching your [investment] portfolio."

Stampf also cautions against over-saving for emergencies since keeping too much cash on hand could mean not having enough of your money invested, which could potentially undermine your retirement goals or other investing goals.

You can avoid over-saving by targeting a specific number for your emergency fund. Maybe a fully funded emergency account for you means having six months' worth of necessary expenses saved; take your monthly expenses and multiply that by six to find your target amount. You might also consider using a budgeting app like Empower to help you figure out what your total monthly expenses look like.

And of course, a high-yield savings account is also the best way to save for large expenses that you foresee having to make in the near future (1–3 years). It's prudent to make sure you save for these expenses on top of your fully-funded emergency account money. And the higher interest rates let you grow your balance just a little quicker. Select ranked the Marcus by Goldman Sachs High Yield Online Savings as the best account for no fees.

The SoFi Checking and Savings also stands out since it offers a welcome bonus after you setup and receive direct deposit payments. You can earn up to $400 with direct deposit*.

"Stashing money in a high-yield savings account for large, near-term purchases (such as a home down payment, new car, or remodeling) can prove beneficial by ensuring the funds are there when you need them and earning a modest amount of interest in the meantime."

A high-yield savings account can sometimes be a happy medium between investing for the long-term and keeping liquid cash on hand for shorter-term large expenses, but it's still important to avoid over-saving. ]

Stampf recommends keeping six to 12 months' worth of expenses in a high-yield savings account for easy access to cash in case of an emergency and saving for larger expenses that are are coming in the short term, like buying a home. Of course, you'll want to also consider your stage of life and your needs when determining how much money to keep in a high-yield savings account.
