An online savings account minimum balance determines how much money you need to open an account, avoid monthly fees, or earn interest. Fortunately, several U.S. banks offer savings accounts with a $0 opening deposit and no monthly maintenance charges.
However, not every account works the same way. Some banks require an initial deposit, charge fees for falling below certain balances, or reserve their highest interest rates for larger deposits.
Understanding these requirements can help you choose an affordable savings account, protect your money, and maximize interest earnings.
Quick Answer
The online savings account minimum balance can be $0, depending on the bank. Ally, Capital One 360 Performance Savings, American Express, and Marcus offer accounts without minimum opening deposits or monthly maintenance fees. CIT Bank Platinum Savings requires $100 to open and $5,000 to qualify for its higher standard APY tier.
Key Takeaways
- Several online savings accounts require $0 to open or maintain.
- Opening deposits and minimum balances to avoid fees are different.

What Does Online Savings Account Minimum Balance Mean?
The online savings account minimum balance is the amount a financial institution may require customers to deposit or maintain under its account terms.
Banks typically use three types of balance requirements.
Minimum Opening Deposit
This is the amount required to initially fund an account. Some banks allow customers to open accounts with $0, while others require $25, $100, or more.
A $0 opening deposit does not necessarily mean customers can leave the account unfunded indefinitely.
Minimum Balance to Avoid Fees
Some banks charge monthly maintenance fees unless customers maintain a specific balance or meet alternative conditions.
For example, an account might waive its fee when customers maintain $300 at the beginning of every day.
Other accounts use an average daily balance calculation.
Minimum Balance to Earn Interest
Some savings accounts pay the same annual percentage yield (APY) across eligible positive balances.
Others offer higher rates only when customers maintain a particular amount.
According to the Consumer Financial Protection Bureau, banks must disclose applicable minimum balances required to open an account, avoid fees, or earn the advertised APY.
Online Savings Accounts With $0 Minimum Balance

| Savings Account | Minimum Opening Deposit | Monthly Fee | Higher APY Balance Requirement |
|---|---|---|---|
| Ally Online Savings | $0 | $0 | No separate threshold |
| Capital One 360 Performance Savings | $0 | $0 | No separate threshold |

Requirements checked October 24, 2026. Banks may change account terms and interest rates.
Ally Bank Online Savings
Ally Bank offers a savings account with no minimum opening deposit and no monthly maintenance fee.
Its savings buckets help customers organize money for emergencies, vacations, and other goals without opening separate accounts.
Ally also supports automatic savings transfers and daily interest compounding.
The bank limits certain withdrawals and transfers to 10 per statement cycle. Repeatedly exceeding that limit can lead to account closure.
Capital One 360 Performance Savings
Capital One requires no minimum opening deposit or ongoing balance.
Customers can earn a variable APY, schedule automatic deposits, and manage their money through online banking.
However, newly approved customers generally have 60 days to fund the account.
American Express High Yield Savings
American Express offers no minimum opening deposit, monthly maintenance fee, or minimum balance to receive its disclosed APY.
Interest compounds daily and is credited monthly.
Customers must initially fund approved accounts within 60 days. Accounts remaining at $0 for 180 days are automatically closed.
Marcus by Goldman Sachs
Marcus offers online savings without a required opening deposit or monthly maintenance fees.
Customers can transfer money through linked external accounts and earn variable interest.
Marcus may close accounts remaining unfunded or without a positive balance for 60 days.
CIT Bank Platinum Savings
CIT Bank requires $100 to open Platinum Savings but does not impose a monthly maintenance fee.
Customers maintaining at least $5,000 qualify for its higher standard APY tier.
Those with smaller balances earn a lower rate, making this account particularly relevant for customers planning to maintain larger savings.
Can an Online Savings Account Stay at $0?
An online savings account minimum balance of $0 does not guarantee that customers can leave an account empty permanently.
Some banks impose funding deadlines or zero-balance closure policies.
| Bank | Funding or Zero-Balance Rule |
|---|---|
| Capital One 360 | Fund within 60 days after approval |
| American Express | Fund within 60 days; closes after 180 days at $0 |
| Marcus | May close after 60 days without a positive balance |
These policies differ from monthly maintenance fees.
An account may remain free while empty but eventually close under the institution’s terms.
Before withdrawing your entire balance, check whether the bank permits extended periods without funds.
Online Savings Account Minimum Balance at Traditional Banks
Traditional banks also allow customers to apply for savings accounts online, but some charge maintenance fees.
| Savings Account | Monthly Fee | Balance to Avoid Fee |
|---|---|---|
| Chase Savings | $5 | $300 at the beginning of each day |
| Bank of America Advantage Savings | $8 | $500 minimum daily balance |
Chase Savings offers additional fee waivers through qualifying automatic transfers, linked accounts, or an account owner under age 25.
Bank of America also provides alternative fee waivers, including qualifying banking relationships and age-based exemptions. It generally waives the fee during the first six months after account opening.
A $5 monthly charge costs $60 annually, while an $8 fee totals $96.
For customers maintaining small balances, these fees can eliminate much of their interest earnings.
How Minimum Balance Requirements Affect APY
Annual percentage yield represents the annual return on savings, accounting for compounding.
Some banks use balance tiers that determine which APY customers receive.
For example, CIT Bank Platinum Savings publishes the following standard variable rates.
| Account Balance | Published APY |
|---|---|
| Below $5,000 | 0.25% |
| $5,000 or more | 3.75% |
Rates effective July 1, 2026 and subject to change.
CIT applies the rate associated with the customer’s balance tier to the entire account balance.
Consequently, a customer with $1,000 pays no monthly maintenance fee but does not qualify for the higher APY.
This illustrates why comparing interest requirements is just as important as checking maintenance fees.
How Much Interest Can You Earn?
Consider a hypothetical account paying a constant 4.00% APY without fees.
| Savings Balance | Estimated Annual Interest |
|---|---|
| $500 | $20 |
| $1,000 | $40 |
| $2,500 | $100 |
| $5,000 | $200 |
| $10,000 | $400 |
These figures assume the balance remains unchanged for one year. They are illustrative rather than actual bank offers.
For example, a $1,000 balance earning $40 annually would still produce a net loss of $20 if the bank charged $60 in yearly maintenance fees.
Therefore, consider both interest earnings and account expenses before choosing a savings product.
Do Promotional Savings Rates Require Minimum Balances?
Some banks advertise promotional APYs that exceed their standard interest rates.
These offers may require a promotional code, qualifying deposit, minimum balance, or enrollment before a deadline.
For example, as of October 24, 2026, CIT Bank advertises a limited six-month APY boost of 0.50 percentage points for eligible Platinum Savings accounts using the promotional code BOOST50.
The advertised boosted APY is 4.25% for balances of at least $5,000, based on the published standard rate.
Promotions can end or change without notice.
Before applying, check the eligibility conditions, promotional duration, and APY that applies after the bonus period.
What Fees Can Online Savings Accounts Charge?
An account without monthly maintenance fees may still charge for certain services.
| Fee Type | When It May Apply |
|---|---|
| Monthly maintenance | Failure to qualify for a fee waiver |
| Outgoing wire transfer | Sending funds through a wire |
| Excess transactions | Exceeding bank-specific transaction limits |
| Paper statements | Requesting mailed statements where applicable |
| Dormancy | Extended inactivity where permitted |
| Early closure | Closing within a restricted initial period |
Not every bank charges these fees.
Reviewing the complete account agreement helps identify expenses that may not appear prominently in advertisements.
How Easily Can You Withdraw Money?
Convenient access matters when comparing accounts with low minimum balances.
Most online savings accounts support electronic transfers to linked checking accounts. However, some do not provide debit cards or direct ATM withdrawals.
For example, Capital One 360 Performance Savings does not support direct ATM withdrawals. Customers can transfer funds to checking or use another supported withdrawal method.
Bank-to-bank transfers can take several business days, and deposited funds may be subject to holds.
Are Savings Withdrawals Limited?
In April 2020, the Federal Reserve removed its former six-per-month limit on convenient savings transfers under Regulation D.
However, banks can still establish their own transaction restrictions.
Customers should check the bank’s withdrawal policy, transfer times, and any associated charges before using the account for emergency savings.
Are Online Savings Accounts With No Minimum Balance Safe?
Eligible savings deposits at FDIC-insured banks receive federal deposit insurance protection.
The standard limit is $250,000 per depositor, per insured bank, per ownership category.
For example, someone holding $100,000 in savings and $50,000 in checking under the same individual ownership category at one insured bank generally has $150,000 in combined insured deposits.
Opening multiple accounts at the same bank does not automatically increase coverage.
Customers can verify an institution through the FDIC BankFind directory.
Are Fintech Savings Apps FDIC-Insured?
Some fintech companies offer savings products through partnerships with insured banks.
However, fintech businesses are not necessarily FDIC-insured institutions.
Deposits placed through these companies may qualify for pass-through insurance when applicable requirements are met.
FDIC insurance protects eligible deposits against the failure of an insured bank, not the bankruptcy of the fintech provider itself.
Review the FDIC’s guidance on third-party banking apps before depositing money.
How to Open an Online Savings Account With $0 Minimum Balance
Opening a savings account online is usually straightforward.
- Compare banks: Review minimum deposits, monthly fees, APYs, and funding deadlines.
- Check deposit insurance: Confirm that the institution is FDIC-insured or an appropriately insured credit union.
- Prepare identification: Gather your name, address, date of birth, and accepted tax identification information.
- Apply online: Complete the application through the institution’s official website or app.
- Fund your account: Transfer money using an accepted method before any required deadline.
- Automate savings: Schedule recurring deposits to build your balance consistently.
For example, saving $10 weekly adds $520 over 52 weeks before interest.
You can often open a standalone savings account without opening checking at the same institution.
Minimum Balance Checklist Before Applying
Before opening an account, review these important conditions.
- Minimum opening deposit

Comparing these conditions can help prevent unexpected fees and ensure the account matches your financial needs.
Conclusion
Choosing an account with a $0 online savings account minimum balance can make saving easier, especially for beginners and customers building emergency funds.
However, opening requirements, interest tiers, monthly fees, funding deadlines, and withdrawal restrictions can affect the account’s real value.
Before applying, compare official bank disclosures and choose a savings account that offers affordable fees, competitive interest, accessible funds, and appropriate deposit insurance.
FAQs About Online Savings Account Minimum Balance
1. Does the online savings account minimum balance include linked checking funds?
Usually not. Savings balance requirements generally apply to the savings account itself unless the bank explicitly allows combined balances or linked accounts to qualify for a fee waiver.
2. Can the online savings account minimum balance affect a sign-up bonus?
Yes. Some banks require a qualifying deposit or a specific balance maintained for a set period to earn a welcome bonus, even when the account’s regular minimum is $0.
3. Is the online savings account minimum balance higher for joint accounts?
Not automatically. Minimum balance requirements usually apply to the account product rather than each owner. However, joint-account conditions may vary by bank.
