How Much Interest $10,000 Earns in a High-Yield Savings Account

Only about 1 in 5 Americans use a high-yield savings account (HYSA), according to a recent CNBC study. And that's a shame, because that means the other 4 in 5 Americans are missing out on easy money.
I've been writing about personal finance for years, and here's something I'll never understand: Why leave free money on the table?! If you're going to keep cash in the bank, you might as well earn something worthwhile on it.
Here's exactly how much you could make with $10,000 sitting in a top HYSA today.
How much interest $10,000 earns at 4.00% APY
Some of the top HYSAs are paying around 4.00% annual percentage yield (APY) right now.
At 4.00% APY, here's how much interest $10,000 would earn in interest:
- In one year: $400
- Per month: About $33
- Each day: About $1.10
Compare that to a traditional bank paying 0.01% APY, where $10,000 would make just $1 in an entire year. The gap is staggering.
I always tell people -- If you were walking along and saw a $1 bill on the ground, would you pick it up? Of course you would. Because it's "free money."
Well, moving your cash pile into a high-yield savings account is kind of like picking up extra money every day (except there's no bending down required -- it just collects and grows in your account). It's one of the easiest wins in personal finance.
Why online banks are better
Bigger interest checks are nice. But online banks have several other benefits that come with high-yield savings accounts:
- FDIC insurance: Just like the big banks, most online HYSAs insure your money up to $250,000.
- Easy transfers: You can usually link your checking account and move money back and forth in a day or two.
- No hidden fees: Many top HYSAs don't charge monthly maintenance fees or have account minimums. Some even waive ATM fees and overdraft charges.
- Better apps and tech: Most online banks focus on a digital-first convenience which lets users manage everything from their phone.
In short, online banks give you all the safety of a traditional bank, but with more modern features and way better returns.
One of my favorites right now is the LendingClub LevelUp Savings account. It pays 4.20% APY with $250+ in monthly deposits and even comes with a debit card linked to your savings. Read our full LendingClub LevelUp Savings review here to learn more.

When an HYSA makes sense
In my opinion, every single American should have a high-yield savings account.
Checking accounts are perfect for day-to-day banking (paying bills, payroll deposits, everyday needs, etc). But an HYSA is the perfect place to save for short-term or medium-term money goals.
Here are some examples of the money to keep inside:
- Emergency funds
- Savings for a vacation or big purchase in the next year
- Stashing a down payment while house-hunting
- Parking cash you may need soon but don't want to risk in the stock market
Even if you don't have much saved, it's still worth opening an account. For example, $1,000 in a 4.00% APY HYSA earns about $40 in a year, versus just $0.10 at a traditional big bank.
