Credit Union vs Online Bank: Where Should You Keep Your Savings?
Both can be safe homes for savings. The differences are in who can join, how you get to your money, and what else comes with the account.
A federally insured credit union and an FDIC-insured online bank give your savings the same standard protection, $250,000 per owner, per institution, per ownership category, so the choice usually comes down to rates, access and the other services you want. Neither type always pays more, so you have to compare the actual accounts.
This guide explains how the two are insured, how credit union membership works, why credit unions say "dividends," and how to check that an institution is really federally insured.
The basic difference
A credit union is a not-for-profit financial cooperative owned by its members. When you open an account, you buy a share and become a member-owner. A bank, including an online bank, is a company owned by shareholders, and you are its customer.
An online bank usually has no branches. You open and manage the account on a website or app. Many credit unions have branches in their area, and many also offer online and mobile banking. Both can offer high-yield savings, and both can offer low ones. The structure does not set the rate.
Insurance: NCUA vs FDIC
This is where the two are closer than most people expect.
Credit union (NCUA)
- Covered by the National Credit Union Share Insurance Fund
- $250,000 per share owner, per insured credit union, per ownership category
- Backed by the full faith and credit of the U.S. government
Online bank (FDIC)
- Covered by FDIC deposit insurance
- $250,000 per depositor, per insured bank, per ownership category
- Backed by the full faith and credit of the U.S. government
Both programs cover deposit products like savings, checking, money market deposit accounts and certificates. Neither covers investments such as stocks, bonds or mutual funds, even if you buy them through the institution. Our FDIC insurance guide explains ownership categories in more detail. The same idea applies at credit unions.
Watch out: Not every credit union is federally insured. A small number of state-chartered credit unions carry private share insurance instead of NCUA coverage. Private insurance is not part of the federal system. Always look the credit union up before you deposit.
How to check that it is federally insured
- Get the full legal name and location. Many institutions have similar names, so note the city and state, or the charter number if it is listed.
- For a credit union, use NCUA's tool. Search Research a Credit Union on NCUA's site. Federally insured credit unions appear there with their charter details.
- For a bank, use FDIC BankFind. Search BankFind to confirm the bank is FDIC insured and see its official name.
- If it is an app, find the partner. Some savings apps are not banks or credit unions. Their disclosures should name the insured bank that holds your money. See how to verify a fintech's FDIC claim.
Credit union membership: who can join
Banks generally take any customer who passes their account-opening checks. Credit unions can only serve members within their "field of membership," which is the group the credit union is chartered to serve. According to NCUA, common ways people qualify include:
- Where you live, work, worship or go to school (community credit unions)
- Your employer or a group your employer belongs to
- Membership in an association or organization tied to the credit union
- A family or household member who is already a member
Each credit union's website explains its own eligibility rules. Read them before you apply, and note any one-time share deposit or membership fee in the account disclosure.
Dividends vs interest: same idea, different word
Credit union savings accounts are often called share accounts, and the earnings are called dividends because members are owners. In practice, a dividend on a share account works much like interest on a bank savings account.
Federal Truth in Savings rules apply to both. Banks follow Regulation DD (12 CFR part 1030) and credit unions follow NCUA's version (12 CFR part 707). Under both, institutions disclose an annual percentage yield, so you can compare a credit union's dividend APY directly with an online bank's APY. Our guide to what APY means covers how it is calculated.
Tip: Credit unions may label rates as "dividend rate" and "APY." Use the APY for your comparison, and check whether the dividend rate is set in advance or declared after the period ends, as the disclosure will explain.
Branches, loans and relationship perks
Beyond the rate, think about what else you want from the institution.
| What to check | Credit union | Online bank |
|---|---|---|
| Insurance | NCUA, $250,000 standard (or private; verify) | FDIC, $250,000 standard |
| Who can open an account | Members in the field of membership | Generally any eligible applicant |
| Earnings called | Dividends, shown as APY | Interest, shown as APY |
| In-person service | Often has local branches | Usually online and phone only |
| Cash deposits | Often at branches; ask about shared networks | Check the bank's options; many limit cash deposits |
| Loans and other products | Ask what members can access | Varies by bank |
| Rate conditions and fees | Read the disclosure | Read the disclosure |
Some credit unions tie better rates or loan pricing to having other accounts with them. Some online banks tie their best rates to direct deposit or balance tiers. Either way, look for the conditions behind the headline number. Our guide to tiered rate traps shows what to look for.

How to compare the two for your savings
You do not have to pick one type forever. Many people keep a checking account at a local credit union and savings at an online bank, or the other way around. To compare a specific pair:
- Confirm both are federally insured using the tools above.
- Write down each APY with the date, plus any balance tiers or conditions.
- Check fees and minimums in each account disclosure, including any membership share deposit.
- Check transfer speed and limits between the savings account and the checking account you use every day.
- Count your total at each institution so you stay within the insurance limits for your ownership categories.
You have $8,000 to save. A credit union offers a hypothetical 3.50% APY with a $5 membership share. An online bank offers a hypothetical 4.00% APY with no conditions. Over a year with no rate changes: $8,000 × 3.50% = $280 at the credit union, and $8,000 × 4.00% = $320 at the online bank. The $40 gap is what you would weigh against branch access or loan perks. Real rates may favor either one, which is why you check.
Frequently Asked Questions
Is my money as safe in a credit union as in a bank?
At a federally insured credit union, your shares are insured by NCUA up to $250,000 per share owner, per credit union, per ownership category. That matches the FDIC's standard coverage at banks, and both are backed by the full faith and credit of the U.S. government. Check that the credit union is federally insured, since a few are privately insured.
Do credit unions pay more on savings than online banks?
Not always. Rates vary by institution and change over time, so neither type always pays more. Compare the APY, conditions and fees for the specific accounts you are considering.
How do I know if I can join a credit union?
Each credit union has a field of membership, such as where you live or work, your employer, an association, or a family member who belongs. Its website or a branch can tell you whether you qualify.
What is the difference between dividends and interest?
Credit unions call savings earnings dividends because members are owners. For a savings account, they work much like interest, and both credit unions and banks disclose the yield as an APY.
How do I check whether a credit union is federally insured?
Search the credit union in NCUA's Research a Credit Union tool. For a bank, use FDIC BankFind. If you cannot find it, ask the institution directly before you deposit.
