Capital One 360 savings accounts earn between 4.00% and 4.35% APY, depending on the account type and current market conditions

Capital One offers two main savings products: the 360 Savings Account and the 360 Money Market Account. The 360 Savings Account typically pays around 4.00% APY, while the Money Market Account pays slightly higher at around 4.35% APY. These rates change regularly—sometimes weekly—based on Federal Reserve decisions and market competition, so the exact rate you receive depends on when you open the account.

The rate you earn also depends on your account balance. Capital One does not tier rates by balance size the way some banks do, meaning you earn the same percentage whether you have $100 or $100,000 in the account. There are no monthly fees, no minimum balance requirement, and no penalty for withdrawals, which means you can move money in and out without losing the interest you have earned.

Interest compounds daily and deposits into your account monthly. This means if you have $10,000 earning 4.00% APY, you would earn roughly $33 per month, though the exact amount shifts slightly each day as interest accrues.

Key Takeaways

  • Capital One 360 Savings Account rates typically fall between 4.00% and 4.35% APY, with the Money Market Account paying the higher end of that range.
  • Rates change regularly based on Federal Reserve policy and market conditions, so you should check the current rate before opening an account.
  • Capital One does not require a minimum balance, charge monthly fees, or penalize you for withdrawals, so you keep all interest earned.
  • Interest compounds daily and deposits monthly, meaning your balance grows slightly each month even if you do not add new money.

How the rate compares to other online banks

Capital One's rates sit in the middle of the online banking market. Some competitors like Marcus by Goldman Sachs, Ally Bank, and American Express offer rates in the same 4.00% to 4.35% range. Others, particularly smaller online banks, occasionally offer slightly higher rates—sometimes reaching 4.50% or above—but these higher rates often come with strings: minimum balance requirements, account restrictions, or rates that drop after an introductory period.

The practical difference between 4.00% and 4.50% on $10,000 is about $50 per year. On $100,000, it is about $500 per year. For most people, the difference is small enough that other factors matter more: whether you already bank with Capital One, whether you want all your accounts in one place, or whether you value the mobile app and customer service experience.

What affects your actual earnings

Your interest earnings depend on three things: the APY rate, your account balance, and how long the money sits in the account. If you deposit $5,000 on the first day of the month and withdraw it on the last day, you earn interest on that $5,000 for roughly 30 days. If you leave it there for a full year, you earn 12 times as much interest.

Capital One calculates interest daily, which means every single day your balance earns a small fraction of the annual rate. On a $10,000 balance at 4.00% APY, you earn roughly $1.10 per day. This daily compounding is why leaving money untouched for longer periods produces noticeably higher returns than moving it frequently.

Inflation also affects what your interest earnings are actually worth. If inflation runs at 3% per year and you earn 4.00% APY, your real return—what your money can actually buy—is roughly 1% per year. This is why savings accounts work best for money you need within a few years, not for long-term wealth building.

How Capital One's rates have moved over time

Capital One's savings rates have risen and fallen with Federal Reserve policy. In 2021 and early 2022, when the Fed kept rates near zero, Capital One's savings account earned 0.40% APY or less. As the Fed raised rates through 2022 and 2023, Capital One raised its rates in response, reaching the current 4.00% to 4.35% range by late 2023. These rates have remained relatively stable since then, though they shift slightly month to month.

The pattern is predictable: when the Fed signals it will hold rates steady, bank savings rates stabilize. When the Fed hints at rate cuts, savings rates typically fall within weeks or months. If you are deciding whether to lock in the current rate, remember that rates can move down as easily as they moved up, and there is no way to predict Fed decisions more than a few months ahead.

When to move money into a Capital One savings account

A Capital One savings account makes sense if you have money you need to keep safe and accessible but do not need for the next few months or years. Examples include an emergency fund, money saved for a down payment on a house or car, or funds set aside for a known expense six months away. The interest rate is high enough that you earn meaningful money without taking on investment risk.

It makes less sense if you need the money within weeks, because the monthly interest deposit will be small. It also makes less sense if you are saving for retirement or a goal more than five years away, because stocks and bonds historically return more over long periods, even accounting for their ups and downs.

How to check the current rate before you open an account

Capital One publishes its current savings rates on its website under the 360 Savings Account and 360 Money Market Account product pages. The rate shown is the rate you will receive when you open the account—Capital One does not offer different rates to different customers based on credit score or other factors. You can also call Capital One at 1-877-383-4802 to confirm the current rate before opening.

When you open the account online, the rate locks in at that moment. If rates drop the next day, you keep the higher rate. If rates rise, you do not get the new rate unless you close the account and reopen it, which is not worth doing for a small rate increase.

Frequently Asked Questions

Do I have to keep a minimum balance to earn the advertised rate?

No. Capital One does not require a minimum balance for either the 360 Savings Account or the Money Market Account. You earn the full APY on whatever balance you maintain, whether it is $1 or $100,000.

Can the interest rate drop after I open the account?

Yes. Capital One can lower its rates at any time, and it typically does when the Federal Reserve cuts rates. You have no protection against rate drops, though you can move your money to another bank if rates fall significantly. You are not locked in.

How often does Capital One change its savings rate?

Capital One typically adjusts rates weekly or monthly, though not every adjustment is a change—sometimes the rate stays the same. The timing depends on Federal Reserve decisions and what other banks are offering. You can check the rate on Capital One's website anytime.

Is the interest I earn taxable?

Yes. Interest earned on a savings account is taxable income. Capital One will send you a 1099-INT form at the end of the year if you earned $10 or more in interest. You report this on your tax return as ordinary income.

What is the difference between the 360 Savings Account and the 360 Money Market Account?

The Money Market Account typically pays a slightly higher rate and allows you to write checks and use a debit card, though you are limited to six withdrawals per month. The Savings Account has no withdrawal limit but does not include check-writing. For most people, the Savings Account is simpler and the rate difference is small.
