A high APY is usually good for a savings account. It helps your money earn more interest, but the rate is only a good deal when the account is insured, the APY is not a short-term promotion, and fees or restrictions do not cancel out the extra return.
APY means annual percentage yield. It shows how much interest an account could earn over one year, including the effect of compounding.
For example, $10,000 at a 5% APY would earn approximately $500 over one year if the rate and balance stayed unchanged.
High APY: Good or Bad at a Glance
| Situation | Is a high APY good? | Why |
|---|---|---|
| FDIC-insured savings account | Usually good | You earn more interest while keeping deposit protection |
| Federally insured credit union account | Usually good | Deposits may receive NCUA share insurance up to applicable limits |
| Account with high fees | Potentially bad | Fees can reduce or eliminate the extra interest |
| Promotional APY | Only temporarily good | The rate may fall after the introductory period |
| High APY on cryptocurrency | High risk | The return may depend on lending, market conditions, platform stability or token prices |
| High APY with a minimum balance | Depends | You may not qualify for the advertised rate on your entire balance |
When Is a High APY a Good Choice?
A high APY works well for money you plan to keep in an emergency fund, house deposit, vacation fund or other short-term savings goal.
A high-yield savings account is usually worth considering when it offers:
- FDIC insurance at a bank or federal share insurance at a credit union
- No monthly maintenance fee
- No unusually high minimum balance requirement
- An ongoing rate rather than a short introductory offer
- Easy access to your money when needed
- Clear terms for how interest is calculated and paid
The FDIC generally insures eligible deposits, including savings accounts, money market deposit accounts and certificates of deposit, up to $250,000 per depositor, per insured bank, per ownership category.
Federally insured credit unions provide comparable NCUA share insurance, generally up to $250,000 for individual accounts.
When Can a High APY Be a Bad Deal?
A high advertised APY can be a bad deal when the account's conditions reduce your actual return.
Check the following before opening the account:
- Is the APY promotional? The account may pay the higher rate for only a limited period.
- Can the rate change? Banks can change the rate on variable-rate accounts, so today's APY may not last.
- Is there a minimum balance? You may earn the advertised rate only when your balance stays above a set amount.
- Are there account fees? A monthly fee can offset the interest you earn. The Consumer Financial Protection Bureau recommends comparing fees and account requirements with the interest you expect to receive.
- Does the rate apply to your entire balance? Some accounts use balance tiers, with different rates at different levels.
- Is the money insured? FDIC insurance does not cover stocks, bonds, mutual funds, crypto assets or other non-deposit investment products, even when a bank offers them.
Is a High APY on Crypto Good or Bad?
A high APY on cryptocurrency can be a bad deal even when the percentage is much higher than a bank savings rate.
Crypto platforms may generate yield through lending, staking, liquidity pools or other strategies. These activities can involve borrower default, platform failure, cybersecurity problems, smart-contract weaknesses and losses caused by changes in the value of the underlying crypto asset. The SEC has highlighted risks and investor protection issues associated with crypto-lending platforms.
A crypto APY of 10%, 20% or more may look attractive, but the asset could lose more value than the yield you earn. The advertised yield may also be paid in a volatile token rather than in U.S. dollars.
What APY Should You Choose?
For a standard savings account, choose the highest ongoing APY from a reputable, insured institution after comparing fees and account conditions.
Before opening the account, confirm:
- Who provides the account
- Whether the bank is FDIC-insured or the credit union is federally insured
- Whether the APY can change
- How long the advertised rate lasts
- Whether a minimum balance is required
- Whether monthly fees apply
- Whether the rate applies to your full balance
- How quickly you can withdraw your money
Bottom Line
Compare the return you keep, not just the number in the advertisement. For emergency savings and short-term cash, check insurance and access first, then compare the ongoing APY after fees.
