Capital One savings accounts pay between 4.00% and 4.35% APY, depending on which account you open

Capital One offers two main savings products: the 360 Savings Account and the Money Market Account. The 360 Savings Account currently pays around 4.00% APY, while the Money Market Account pays around 4.35% APY. These rates change regularly—sometimes weekly—based on what the Federal Reserve does with interest rates, so the exact percentage you see today may be different next month.

The difference between the two accounts matters less than you might think. The Money Market Account requires a higher opening deposit (usually $10,000 versus $0 for the 360 Savings), but both have no monthly fees, no minimum balance requirements after you open the account, and unlimited withdrawals. The rate difference is usually less than 0.50%, which means on a $10,000 balance, you're looking at a difference of roughly $50 per year.

Interest compounds daily and deposits into your account monthly. That means if you have $10,000 earning 4.00% APY, you'll see roughly $33 added each month (though the actual amount varies slightly depending on how many days are in the month). The money starts earning interest the day you deposit it.

Key Takeaways

  • Capital One's 360 Savings Account pays around 4.00% APY with no opening deposit requirement, while the Money Market Account pays around 4.35% APY but requires $10,000 to open.
  • Both rates change regularly based on Federal Reserve decisions, so the percentage you lock in today will likely be different in three to six months.
  • Interest compounds daily and deposits monthly, so a $10,000 balance earning 4.00% generates roughly $33 per month in interest.
  • There are no monthly fees, no minimum balance requirements after opening, and no limits on how many times you can withdraw money from either account.

How the rates compare to other banks right now

Capital One's rates sit in the middle of the current market. Some online banks like Marcus, Ally, and American Express offer rates between 4.25% and 4.50%, while others offer slightly less. Traditional brick-and-mortar banks typically offer 0.01% to 0.50%, so moving money to Capital One or any online bank makes a real difference if you're holding cash for more than a few months.

The gap between Capital One and the highest-paying accounts is usually less than 0.50% APY. On $10,000, that's a difference of about $50 per year. On $100,000, it's roughly $500 per year. If you already have a Capital One checking account or use their other products, the convenience of keeping everything in one place may outweigh chasing an extra 0.25% elsewhere.

What happens to your rate when the Federal Reserve changes rates

Capital One doesn't may provide any rate for any length of time. When the Federal Reserve raises or lowers its benchmark rate, banks adjust their savings rates within days or weeks. If the Fed raises rates, Capital One typically raises its savings rates too. If the Fed cuts rates, Capital One cuts its rates as well.

You won't see a notification warning you that your rate is about to drop. Capital One will straightforward change the rate on your account, and you'll see the new percentage if you log in or check your statement. This is standard across all banks—there's no "locked-in" rate for savings accounts the way there is for certificates of deposit (CDs).

If you want to lock in a rate, Capital One does offer CDs with terms ranging from three months to five years. A five-year CD might currently pay 4.50% to 4.75% APY, depending on when you open it, and that rate stays the same for the full five years. The trade-off is that you can't touch the money without paying an early withdrawal penalty.

How to track your interest earnings and see your current rate

Log into your Capital One account online or through the mobile app. Your current APY appears on the account details page, usually labeled "Annual Percentage Yield" or "Current Rate." Your monthly interest deposit shows up as a separate transaction in your account history, typically posted on the first business day of the month.

Capital One also sends an annual statement showing your total interest earned for the year. This number matters for taxes—you'll need it when you file, since interest income is taxable. Capital One will send you a 1099-INT form if your interest earnings exceed $10 for the year, which they almost certainly will.

Why Capital One's rates matter less than you think if you're saving short-term

If you're saving for something you need in the next three to six months, the interest rate barely matters. On $5,000 earning 4.00% APY for six months, you'll earn about $100. On the same amount earning 4.50%, you'd earn about $112. The difference is $12 over half a year. The real value of a savings account at this rate is that your money is safe, accessible, and earning something rather than sitting in a checking account earning nothing.

The interest rate becomes meaningful when you're holding larger amounts for longer periods. If you have $50,000 sitting in savings for two years, the difference between 4.00% and 4.50% is roughly $500. That's worth shopping around for. But if you're moving money in and out regularly or only keeping a few thousand dollars on hand, the rate difference between banks is noise compared to the benefit of having the money in a savings account at all.

What you should know about Capital One's interest calculation

Capital One uses daily compounding, which means interest is calculated on your balance every single day, including interest you've already earned. This is the best method for you as a saver—it generates slightly more interest than monthly or quarterly compounding. The difference is small (usually less than $5 per year on a $10,000 balance), but it works in your favor.

Interest posts monthly, not daily. You won't see the interest hit your account until the first business day of the next month. Until then, it's accruing behind the scenes. This doesn't affect how much you earn—it's just a timing thing.

Frequently Asked Questions

Does Capital One charge fees that reduce my interest earnings?

No. The 360 Savings Account and Money Market Account have no monthly maintenance fees, no overdraft fees, and no fees for transfers or withdrawals. The interest you earn is the interest you keep. Some banks charge monthly fees that can wipe out several months of interest, so Capital One's no-fee structure is a real advantage.

Can I move money between my Capital One savings account and checking account without losing interest?

Yes. You can transfer money between your Capital One accounts as many times as you want without penalty or loss of interest. Interest accrues on whatever balance sits in your savings account on any given day, regardless of how many transfers you've made.

What happens to my interest if I withdraw money mid-month?

You keep all the interest you've earned up to that point. Interest accrues daily, so if you withdraw on the 15th, you've earned interest on your balance for the first 15 days of the month. You don't forfeit anything by withdrawing early, unlike with CDs.

Is my money safe if Capital One's interest rate drops?

Your money is safe—that's separate from the interest rate. Capital One is FDIC-insured, meaning deposits up to $250,000 are protected by the federal government even if the bank fails. The interest rate can drop, but your principal balance cannot.

How does Capital One's rate compare to a CD if I'm willing to lock up my money?

Capital One's five-year CDs typically pay 0.25% to 0.50% more than the savings account rate. If the savings account pays 4.00%, a five-year CD might pay 4.50%. You earn more, but you can't touch the money without paying a penalty. For money you won't need for five years, a CD makes sense. For money you might need sooner, the savings account's flexibility is worth the lower rate.
