Credit Unions vs Banks: Where Should You Park Your Savings?
The gap between credit union and traditional bank deposit rates can be stark. In 2024, top credit union CDs and savings accounts offered 5–5.5% APY, while the average traditional bank savings rate hovered near 0.5%. On a $10,000 deposit for one year, that's roughly $470 extra from a credit union.
Online banks (Marcus, Ally, SoFi, etc.) have narrowed the gap by cutting overhead. They typically offer rates close to credit unions but are open to anyone — no membership required. They are FDIC insured and function like any bank account.
Traditional brick-and-mortar banks remain the most convenient for in-person services, but their savings rates are consistently the lowest in the market. They rely on customer inertia — many depositors never shop around despite leaving hundreds of dollars per year on the table.
All deposits at federally insured credit unions (NCUA) and banks (FDIC) are protected up to $250,000 per institution per depositor — so there is no meaningful safety trade-off between them. The only deciding factors are rate, convenience, and membership eligibility.
Frequently Asked Questions
No. APY (Annual Percentage Yield) includes the effect of compounding, while the stated interest rate does not. APY gives a more accurate picture of what you actually earn over a year, especially for accounts that compound monthly or daily.
Rate is important, but also consider: minimum balance requirements, early withdrawal penalties (for CDs), accessibility, and whether the institution's services meet your needs. For emergency funds, a high-yield savings account beats a CD since you can access the money without penalty.
