Move it to savings or a money market account to earn interest instead of letting it sit idle

Money in a checking account typically earns little to no interest, even at banks that offer interest-bearing checking. If you have more than you need for monthly bills and emergencies, moving the surplus to a savings account, money market account, or certificate of deposit (CD) lets that money work for you. The difference between 0% and 2% to 5% annual interest adds up quickly on larger balances.

The key decision is how soon you might need the money. If it's truly extra—beyond your emergency fund and next month's expenses—you have options that range from instantly accessible to locked away for higher returns. Each choice involves a trade-off between access and interest rate.

Key Takeaways

  • Checking accounts earn little or no interest, so balances above your emergency fund and monthly spending should move elsewhere.
  • A high-yield savings account at an online bank typically pays 4% to 5% annual interest and lets you withdraw money within one to three business days.
  • Money market accounts offer similar rates to savings but may require higher minimum balances and limit how often you can withdraw.
  • Certificates of deposit lock your money for a set term (three months to five years) in exchange for higher interest rates, usually 4% to 5.5%.
  • If you have $10,000 or more sitting idle, moving it to a high-yield savings account could earn $400 to $500 per year instead of nearly nothing.

High-yield savings accounts: fastest access with solid interest

A high-yield savings account is the simplest move for extra checking money. Online banks like Marcus, Ally, American Express Personal Savings, and Discover offer rates between 4% and 5.35% annually, compared to 0% to 0.01% at most traditional banks. You can open one in minutes, and transfers from your checking account arrive within one to three business days.

The catch is minimal: you can only withdraw six times per month without penalty (a federal rule that applies to most savings accounts), though most banks no longer enforce this strictly. For money you might need in the next few months, this is the right choice. A $10,000 balance earning 4.5% generates $450 per year—money you would not earn in checking.

You do not need to keep all your savings in one place. Many people keep one to two months of expenses in checking, three to six months in a high-yield savings account at their main bank, and additional savings elsewhere. This spreads your money across different institutions and interest rates.

Money market accounts: higher minimums, similar rates

A money market account combines features of checking and savings. It typically offers a debit card or checkbook for withdrawals, earns interest (currently 4% to 5% at online banks), and requires a higher minimum balance—often $2,500 to $10,000 to open or to earn the advertised rate.

Money market accounts are useful if you want check-writing ability on your savings without keeping everything in checking. However, they usually limit withdrawals to three to six per month, and rates vary more widely than high-yield savings accounts. If you have a large balance and want both access and interest, this works. For smaller amounts, a high-yield savings account is usually simpler.

Compare the minimum balance requirement and withdrawal limits before opening. Some banks advertise high rates but only pay them on balances above $100,000, while others have no minimums at all.

Certificates of deposit for money you will not need soon

A certificate of deposit (CD) locks your money for a set period—typically three months, six months, one year, or five years—in exchange for a may provide interest rate. Current CD rates range from 4% to 5.5% depending on the term, and longer terms usually pay more. If you have money you know you will not touch for a year or more, a CD often beats a savings account.

The trade-off is clear: withdraw early and you pay a penalty, usually three to six months of interest. A one-year CD paying 5% with a three-month early withdrawal penalty means you lose $12.50 per $1,000 if you pull money out at month six. This makes CDs wrong for money you might need unexpectedly.

Some banks offer no-penalty CDs that let you withdraw without penalty after a short waiting period (usually seven days). These pay slightly less than regular CDs but give you an escape route. If you are unsure whether you will need the money, a no-penalty CD or high-yield savings account is safer than a traditional CD.

How much should stay in checking versus move out

A common rule is to keep one to two months of expenses in checking and the rest in savings. If your monthly bills are $3,000, keep $3,000 to $6,000 in checking for immediate needs and move anything above that. This covers unexpected expenses without forcing you to wait for transfers.

Your emergency fund—typically three to six months of expenses—should live in a savings account, not checking. It earns interest there and stays separate from your daily spending, making it less tempting to dip into. Once your emergency fund is full, any additional money is truly extra and can go toward goals: a down payment, a vacation, debt payoff, or long-term investing.

If you receive a large deposit—a tax refund, bonus, or inheritance—do not leave it in checking. Move it within a few days to a savings account or CD. The longer it sits in checking earning nothing, the more interest you lose.

Moving money between accounts without fees

Transfers between your own accounts at the same bank are free and usually instant or next-business-day. Transfers between different banks take one to three business days through the ACH system (Automated Clearing House) and are also free. Never use a wire transfer for routine moves—wires cost $15 to $30 and are meant for urgent, large transfers.

Set up a transfer once and you can repeat it automatically. Many people move a fixed amount from checking to savings each payday, which removes the decision-making and builds savings without thinking about it. Your bank's app or website lets you schedule recurring transfers at no cost.

If your bank charges a monthly fee for checking, moving excess money out may help you avoid it. Some banks waive fees if you keep a minimum balance in checking, while others waive them if you have a linked savings account with a certain balance. Read your account agreement or call to confirm what triggers a fee.

Tax implications of interest earned

Interest you earn on savings accounts, money market accounts, and CDs counts as taxable income. Banks send you a 1099-INT form in January if you earned $10 or more in interest during the year. You report this on your tax return, and it is taxed at your ordinary income rate.

This does not mean you should avoid earning interest—the tax is small compared to the interest itself. A $10,000 balance earning 4.5% generates $450 in interest. If you are in the 22% tax bracket, you owe about $99 in tax, leaving you $351 ahead. That is still $351 you would not have earned in checking.

Keep records of your interest earnings if you have multiple accounts. Your bank reports the total to the IRS, but you need to track it yourself for your records and to catch errors on the 1099-INT.

Frequently Asked Questions

Is my money safe in a high-yield savings account at an online bank?

Yes, as long as the bank is FDIC-insured, which nearly all online banks are. FDIC insurance covers up to $250,000 per account holder per bank, so your balance is protected even if the bank fails. Check the bank's website for the FDIC certificate number to confirm coverage.

Can I move money back to checking if I need it?

Yes. Transfers from savings to checking take one to three business days through ACH, or you can use your bank's app to move money instantly if both accounts are at the same bank. Plan ahead if you know you will need the money on a specific date.

What if interest rates drop after I open a CD?

You keep the rate you locked in when you opened the CD. If rates fall, your CD still pays the original rate until it matures. If rates rise and you want a higher rate, you would need to wait for the CD to mature and open a new one, or pay an early withdrawal penalty.

Should I split my savings across multiple banks?

You do not have to, but some people do to maximize FDIC insurance or to separate money by goal. If you have $500,000 in savings, keeping $250,000 at one FDIC-insured bank and $250,000 at another protects all of it. For smaller amounts, one bank is simpler.

What if my checking account pays interest—should I keep money there?

Probably not. Interest-bearing checking accounts typically pay 0.01% to 0.5%, far below high-yield savings rates of 4% to 5%. The only reason to keep extra money in checking is if you need instant access without waiting for transfers, which is rare for truly extra money.
