Part of the Banking 101 guide.
The right bank depends on what you value most — in-person service, the highest possible interest rate, or the lowest possible fees. Here is how the three main options actually compare.
Comparison
| Type | Interest Rates | Fees | Access | Best For |
|---|---|---|---|---|
| Traditional bank | Typically low | Often has monthly fees unless waived | Branches, ATMs, full product range | People who want in-person service and a wide branch network |
| Online-only bank | Typically higher | Often minimal or no monthly fees | App and website only, wide ATM networks via partnerships | People comfortable managing money entirely digitally |
| Credit union | Often the most competitive | Often the lowest fees | Limited branches; membership eligibility required | People who qualify for membership and want the best overall rates |
Membership Eligibility for Credit Unions
Unlike banks, credit unions require membership, which is often tied to your employer, location, military service, or association with a specific group. Many credit unions have broadened eligibility significantly in recent years — some allow anyone to join by making a small donation to an affiliated nonprofit, so it is worth checking even if you assume you do not qualify.
What to Check Before Committing
- Fee schedule — monthly maintenance, overdraft, out-of-network ATM fees, and whether they can be waived.
- Minimum balance requirements — some accounts charge a fee if your balance drops below a set threshold.
- ATM network size — especially important for online banks, since you cannot deposit cash at a branch.
- Mobile app quality — since most day-to-day banking now happens on a phone regardless of bank type.
