Choose a high-yield savings account by comparing its current APY and rate terms with fees, balance requirements, access, and deposit insurance—not by headline APY alone. A savings account’s APY is generally variable, so it describes the yield under a standardized calculation, not a promise that the rate will last for a year. If you can leave money untouched for a defined period, compare certificates of deposit (CDs) as well.
Compare the full account, not just its APY
Regulation DD requires disclosures for deposit accounts that include the APY, interest rate, minimum-balance requirements, account-opening terms, and fee schedules. Use those disclosures to compare offers on the same basis. The CFPB’s Regulation DD overview was most recently amended April 19, 2023.
- Record the APY and the date you checked it. Note whether the rate is variable or promotional, and how long any introductory rate applies.
- Check balance tiers. Find out whether the advertised APY applies to the entire balance or only a portion, and what APY applies at each tier. Regulation DD requires APY disclosures for applicable balance tiers.
- Read the minimums. Check the minimum opening deposit and any balance needed to earn the stated APY or avoid a fee.
- Compare fees with your likely balance and habits. A higher APY may not compensate for a monthly fee if you cannot meet the waiver conditions.
For introductory variable-rate offers, the APY calculation assumes the introductory rate lasts for its stated term, then uses the non-introductory rate that would otherwise have been in effect for the rest of the year. That calculation is not a forecast of future rates. See Appendix A to Regulation DD.
Understand what can change after you open the account
A quoted APY is an annualized calculation based on the account’s rate and compounding assumptions. For a variable-rate account without an introductory premium or discount, the CFPB’s calculation rule uses the initial interest rate and assumes it stays unchanged during the year solely to calculate the APY. The institution may change the rate, so the APY is not a fixed-rate promise.
#1 Best Overall
The reviewed Regulation DD provision says institutions need not provide notice under that section when the interest rate and corresponding APY change on a variable-rate account. Do not assume you will receive advance warning of a rate decrease. The CFPB’s request for information on variable interest rates describes a petition seeking timely disclosure; a petition is not an adopted rule.
Check the account’s current rate and terms before opening, and revisit them periodically—particularly after a broad rate move or when the account no longer seems competitive. This is a useful comparison habit, not a guarantee of a particular notice or a forecast of future rates.

Check fees and access requirements
Banks and credit unions may charge monthly maintenance fees. Common ways to avoid them include maintaining a specified minimum balance or arranging direct deposit. The CFPB says institutions must disclose the fee and how to avoid it when the account is opened. Review the CFPB’s guidance on account fees and confirm that any waiver condition fits how you actually use the account.
Also verify how money moves in and out. Check transfer timing, transaction limits, available withdrawal methods, and any minimum deposit. Terms differ by institution. The CFPB notes that money market deposit accounts, in particular, may limit some check, debit-card, or electronic transactions and may require a minimum deposit.
Verify deposit insurance and account ownership
Confirm whether the institution is a bank or credit union, and check how your ownership category and other deposits at that institution affect coverage. CFPB guidance says bank and credit-union money market deposit accounts are insured up to $250,000 per owner category, subject to applicable coverage rules. Use the FDIC or NCUA coverage tools linked from the CFPB’s money market account explanation to check your situation.
Do not confuse a money market deposit account with a money market mutual fund. The latter is an investment, not a savings or checking account, even if the fund offers check-writing. It is not equivalent to an insured bank or credit-union deposit.
Rank #4
Compare savings accounts with other cash options
| Option | Rate behavior | Access | What to compare |
|---|---|---|---|
| High-yield savings account | Variable APY may change; the current APY is not guaranteed for a year. | Designed for savings access, but verify the institution’s transfer and withdrawal terms. | APY and date checked, promotional period, balance tiers, minimums, fees, access, and insurance. |
| Money market deposit account | Rates and terms vary by institution. | May limit some checks, debit-card, or electronic transactions and may require a minimum deposit. | APY, transaction limits, minimum deposit, fees, and FDIC or NCUA coverage. |
| Certificate of deposit (CD) | Rate and term are set by the offer; compare the specific terms. | Funds are generally committed for a stated term; early withdrawal carries a penalty. | Term, rate, early-withdrawal penalty, maturity date, and insurance. |
| Money market mutual fund | Investment product; it is not a deposit-account rate offer. | Access and product terms vary. | It is not an insured savings account; evaluate its investment risks and protections separately. |
If liquidity is less important than locking in terms for a defined period, compare CDs by term, interest rate, and early-withdrawal penalty, then match the maturity date to when you expect to need the money. The CFPB’s CD guide explains these comparison points.

A practical account-selection checklist
- Set the access requirement. Decide how quickly you may need the money and whether transfer timing or withdrawal limits are acceptable.
- Compare current offers on the same date. Record each APY, rate type, promotional duration, balance tier, and minimum opening deposit.
- Calculate the fee trade-off for your circumstances. Identify monthly charges and waiver conditions, then check whether your balance or deposit behavior meets them.
- Check the institution and coverage. Verify the provider type and use the appropriate FDIC or NCUA tool to assess insurance based on your ownership category and other deposits.
- Consider a CD only if the term fits. Compare its rate and maturity with the savings account’s changing rate and more flexible access, including the early-withdrawal penalty.
- Recheck after opening. Review the current APY and terms periodically rather than assuming the opening rate will continue.
