Capital One 360 savings accounts do earn interest, but the rate changes with the market

Capital One 360 savings accounts earn variable interest, meaning the rate the bank pays you goes up or down based on what the Federal Reserve does with its benchmark rate. You will not see a fixed percentage locked in for a year or more. The rate you earn today may be different next month.

The actual rate depends on which Capital One savings product you hold. Capital One 360 Money Market accounts and regular savings accounts both earn interest, but at different rates. You can see the current rate on Capital One's website before you open an account, and the bank will show you the rate on your account dashboard once you are a customer.

Interest deposits into your account monthly. You do not have to do anything to receive it—the bank calculates your balance at the end of each day, compounds the interest daily, and credits the total to your account once a month.

Key Takeaways

  • Capital One 360 savings accounts earn variable interest that moves with Federal Reserve rate changes, not a fixed rate you lock in.
  • Interest is calculated daily on your account balance and deposited once per month.
  • Money Market accounts and regular savings accounts earn different rates; check Capital One's website to compare current rates.
  • There are no monthly fees on Capital One 360 savings accounts, so all interest you earn stays in your account.
  • You can move money between your Capital One savings and checking accounts online without waiting periods or transfer limits.

How the interest rate is set and when it changes

Capital One does not announce rate changes on a schedule. Instead, the bank adjusts rates when it chooses, usually in response to Federal Reserve decisions. When the Fed raises its benchmark rate, banks typically raise savings rates within days or weeks. When the Fed cuts rates, banks often cut savings rates faster than they raised them.

You will not receive a notice before a rate drop, but you can check your rate anytime by logging into your Capital One account or visiting their website. The rate you see is the rate you are earning right now. If you want to track changes over time, write down the rate when you open your account and check it monthly.

Capital One publishes current rates on its website for both Money Market and regular savings accounts. The Money Market account typically earns a higher rate because it requires a higher minimum balance and has slightly different terms.

Minimum balance requirements and account limits

Capital One 360 savings accounts have no minimum balance requirement to open or maintain the account. You can deposit $1 and start earning interest immediately. There is also no monthly maintenance fee, which means the bank does not charge you to keep the account open.

The Money Market account does have a higher minimum balance to earn the advertised rate—check Capital One's current terms, as this minimum can change. If your balance drops below that threshold, you will earn a lower rate on the full balance.

Capital One does limit the number of transfers you can make out of a savings account to six per month (this is a federal rule, not a Capital One rule). Transfers include moving money to another bank, paying a bill through the savings account, or sending money to another person. Transfers between your own Capital One checking and savings accounts do not count toward this limit.

How interest compounds and when you see it in your account

Capital One compounds interest daily, meaning the bank calculates interest on your balance every single day, including interest you earned the day before. This daily compounding works in your favor because you earn interest on your interest.

The monthly deposit is when you actually see the money. On the last business day of each month, Capital One adds up all the daily interest it calculated and deposits the total into your savings account. If you have $10,000 earning 4.00% annual interest, you would see roughly $33 deposited at the end of the month (though the exact amount depends on the number of days in that month and the current rate).

You can reinvest that interest by leaving it in the account, or you can transfer it out. Either way, it is yours to keep.

Comparing Capital One savings to other banks

Interest rates across all banks move together because they all respond to the same Federal Reserve decisions. At any given moment, some banks offer slightly higher rates than others, but the differences are usually small—often less than 0.25% per year.

What matters more than chasing the highest rate is whether the account fits how you use money. Capital One 360 has no monthly fees, no minimum balance, and no transfer delays between your checking and savings. Some banks offer slightly higher rates but charge monthly fees or require larger balances. Over a year, the fee might cost you more than the rate difference saves you.

If you are comparing rates, use the Annual Percentage Yield (APY) number, not the interest rate. APY includes the effect of daily compounding and shows you the true return over a year.

What happens to your interest if you close the account

If you close your Capital One 360 savings account, you receive all interest earned up to the day you close it. The bank does not forfeit any interest or charge a penalty for closing early. You will receive the full balance—principal plus all accrued interest—in whatever way you request: transfer to another bank, check, or wire.

Interest accrues through the last day your account is open. If you close on the 15th of the month, you earn interest through the 15th, and that interest is included in your final payout.

How to track your interest earnings over time

Capital One shows your monthly interest deposit on your account statement. You can download statements from your online account or request them by mail. Each statement lists the interest earned that month and your running balance.

If you want to see how much interest you have earned since you opened the account, add up the monthly deposits shown on your statements, or log into your account and look at the transaction history. Capital One does not provide a year-to-date interest total on the dashboard, so you may need to calculate it yourself or request a statement that covers the full period.

For tax purposes, Capital One will send you a 1099-INT form at the end of the year if you earned $10 or more in interest. This form reports your interest income to the IRS, and you will need it to file your taxes.

Frequently Asked Questions

Can I earn interest on money in my Capital One checking account?

Capital One 360 checking accounts do not earn interest. Only the savings and Money Market accounts earn interest. If you want to earn interest on all your money, keep your checking balance low and move extra funds to savings.

What if the interest rate drops to nearly zero?

Interest rates can fall to very low levels during economic downturns, but you will still earn something as long as the rate is above zero. Your money is safer in a bank account than in cash, and you earn whatever the market rate is at that time. You can always move your money to a different bank if another offers a better rate.

Is the interest I earn taxable?

Yes. Interest earned in a savings account is taxable income. Capital One reports it to the IRS on a 1099-INT form if you earn $10 or more per year. You must report this interest on your tax return.

Do I have to do anything to keep earning interest?

No. As long as your account is open and has money in it, you earn interest automatically every day. You do not need to make deposits, meet activity requirements, or take any action.

What happens to my interest if I do not withdraw it?

Interest you do not withdraw stays in your account and earns interest itself the next month. This is how compounding works—your money grows faster over time because you earn interest on your interest.
