Frequently Asked Questions
What is an online checking account?
An online checking account is a checking account that you primarily access through a website or mobile app rather than at a physical branch. Many are offered by online-only banks or fintechs, while others come from traditional banks that also have brick-and-mortar locations. Common features include mobile check deposit, free debit card, ATM access through partner networks, and Zelle or similar peer-to-peer transfers.
Are online checking accounts safe?
Yes, when the institution is FDIC- or NCUA-insured. FDIC insurance covers deposits at member banks up to $250,000 per depositor, per ownership category. NCUA insurance provides equivalent coverage at federally insured credit unions. Fintechs that are not banks themselves (such as Chime, SoFi pre-charter, or Upgrade) hold customer deposits at insured partner banks — the same FDIC coverage applies, but it flows through the partner. Always confirm the FDIC or NCUA status before opening an account.
Do online checking accounts pay interest?
Some do, some do not. Among the accounts in this guide, several pay interest on the checking balance — including Alliant, Ally, Axos, Capital One 360, Connexus Xtraordinary, E*TRADE Max-Rate, nbkc, SoFi, and U.S. Bank Smartly (at very low rates). Others, such as BMO Smart Advantage, Chime, PNC Virtual Wallet (Spend account), Upgrade, and Varo, do not pay interest on the checking balance itself. Several of the no-interest accounts pair with companion savings accounts that do earn higher APYs.
What are the typical fees on a checking account?
The most common fees are monthly maintenance fees (typically $5 to $25, often waivable), overdraft fees (historically $30 to $36, though many banks have eliminated or reduced these), out-of-network ATM fees (usually $2.50 to $3 per transaction plus the ATM owner’s surcharge), and foreign transaction fees (typically 1% to 3%). Wire transfers, paper statements, and stop-payment requests can also carry fees. Many of the accounts in this guide have eliminated overdraft fees entirely and waive monthly fees through balance, direct deposit, or paperless statement requirements.
How do I switch to a new online checking account?
The basic process: open the new account and fund it with a small initial deposit, update your direct deposit with your employer or income source, move any automatic bill payments and recurring debits to the new account, monitor your old account for at least one to two cycles to make sure no transactions are missed, then close the old account in writing. Some banks (including Upgrade and others) provide a switch kit that automates the direct-deposit and bill-pay updates.
Can I deposit cash into an online checking account?
It depends on the institution. Banks with branches and deposit-enabled ATMs (Capital One, U.S. Bank, BMO, PNC) make cash deposits straightforward. Online-only banks and fintechs typically rely on retail partners: Ally accepts cash deposits at Walmart for free, Chime allows free deposits at Walgreens (with fees at most other retailers), and SoFi, Varo, and Axos use Green Dot retail locations with fees up to about $5. nbkc allows cash deposits at its Kansas City branches and certain ATMs.
