A bank bonus can beat 4.5% APY for a smaller balance in the first year, but the payment is one-time and may come with deposit, timing, and fee requirements. A 4.5% APY account or certificate earns interest over time, while a bonus pays a fixed dollar amount after you meet its terms. For example, Wells Fargo's $325 Everyday Checking offer equals about one year of 4.5% interest on $7,222 before tax. That comparison changes for larger balances and for money you plan to keep earning interest beyond the first year.

Compare the dollar amount, not just the headline
Divide the bonus by 0.045 to find the balance that would earn the same amount in one year at 4.5% APY. Using that method, a $325 bonus matches roughly $325 of annual interest on $7,222. Below that balance, the $325 bonus can produce more first-year value than 4.5% interest.
Above it, 4.5% APY produces more than $325 over a full year, assuming the money remains deposited. The crucial difference is repeatability. Interest continues to accrue under the account's terms; a new-customer bonus does not.
A 4.5% APY offer may limit access to your money
CPM Federal Credit Union advertised a nine-month certificate at 4.50% APY, effective September 1, 2026. The offer requires at least $2,000 in new money. CPM Federal Credit Union's certificate special also states that early-withdrawal penalties may apply and that online certificates cannot be closed or withdrawn during their first 90 days.
That makes the offer a certificate, not a fully liquid savings account. A certificate can suit funds you can leave untouched for its term, but it is less flexible for emergency savings or a purchase you expect soon. Before choosing yield over a bonus, match the account's access rules to when you may need the cash.
Can you meet the bonus requirements naturally?
Wells Fargo's active Everyday Checking offer pays $325 to new customers who open with an offer code by October 13, 2026 and receive at least $1,000 in qualifying electronic deposits within 90 days. The offer is most practical when those deposits already fit your normal payroll or income flow. Wells Fargo's checking offer terms set out the deadline and deposit requirement. Other offers can demand more.
TD Bank's $200 Signature Savings bonus requires a $10,000 deposit within 20 days, followed by maintaining at least $10,000 for 90 more days; TD may pay the bonus by day 180 and may deduct it if the account closes within six months. American Express requires $7,500 in qualifying employer or government direct deposits within 90 days for its $300 Rewards Checking bonus. Transfers, checks, P2P payments, and most bank-to-bank ACH transfers do not qualify. Use this short checklist before applying:.
- Confirm the account-opening deadline and any required offer code.
- Identify which incoming payments count as qualifying deposits.
- Check the required balance and how long it must remain in the account.
- Note the expected bonus-payment date and account-closing restrictions.
Fees can turn a winning bonus into a weaker deal
A bonus should be compared with every fee you expect to pay while qualifying and afterward. Wells Fargo's Everyday Checking account has a $15 monthly service fee unless you qualify for a waiver, including through $500 in qualifying electronic deposits or a $1,500 minimum daily balance each fee period. Wells Fargo's offer page describes those waiver paths.
A $325 bonus can therefore lose value if the account stays open with monthly fees after the promotional requirement ends. Decide in advance whether you will continue meeting a waiver condition or close the account only after all bonus and account terms allow it. Also account for taxes. Wells Fargo says customers are responsible for taxes and reports bonuses as required, while American Express says its welcome bonus may be reported on Form 1099.
Choose the offer that fits the job for your cash
Choose a bank bonus when you can meet the requirements through normal deposits, avoid ongoing fees, and are comfortable tracking the payout date. It can be especially compelling when your eligible balance is well below the bonus-equivalent balance. Choose 4.5% APY when you want a stated return on a balance that can remain deposited and the account's access restrictions fit your plans.
CPM's certificate structure, for example, favors money you can set aside for nine months. Read the disclosures before opening. CFPB rules require advertised bonus offers to disclose the APY, time requirement, relevant minimum balances, and when the bonus will be provided. The CFPB's Regulation DD commentary explains those required bonus disclosures.
