A bank bonus is a one-time cash payment for opening an account and meeting set conditions, such as a minimum deposit or direct deposit. A 5% APY savings account pays ongoing interest. Which pays more depends on how much money you have, how long you must park it, and whether the rate holds. For modest balances over short periods, a bonus often wins.
For large balances held a long time, interest can catch up or pull ahead. APY, or annual percentage yield, is the yearly return including compounding. It is not locked in. Most high-yield savings rates are variable, so a 5% rate today can fall later. A fair comparison turns both options into dollars earned over the same period, after taxes and fees.

How to Compare the Two in Dollars
Start with the interest your money would earn during the bonus holding period. Take the deposit, multiply it by the apy, then scale it to the months required. For example, $5,000 at 5% APY earns roughly $250 over a year, or about $125 over six months. Then compare that to the bonus.
Suppose a checking account pays a $300 bonus but requires $5,000 kept there for six months at near-zero interest. The bonus beats the roughly $125 in savings interest you gave up, so you come out about $175 ahead before taxes. Now scale the deposit up. If the same $300 bonus requires $25,000 for six months, 5% savings would earn about $625 in that time. Here the savings account wins by roughly $325, even though the bonus looks bigger on the ad.
Opportunity Cost Is the Real Price of a Bonus
The money you move to chase a bonus stops earning elsewhere. That lost interest is the opportunity cost, and it is the number most bonus ads leave out. A bonus paid on a checking account with no interest costs you the full savings yield for every month the money sits there. Direct deposit bonuses often cost less.
Your paycheck flows in and can move back out soon after, so the balance stays low. When a bonus asks only for qualifying direct deposits and no minimum balance, the opportunity cost can be close to zero. Savings account bonuses sit in between. Some banks pay a bonus on a savings account that also earns interest. In that case you collect both, and the comparison is the new account's total return against your current account's return.
What to Verify Before Opening a Bonus Account
Bonus terms decide whether you get paid at all. Read the full terms page, not the headline, and check these points: Save a screenshot or PDF of the terms on the day you apply. offers change, and a copy helps if the bonus fails to post.
- **Qualifying activity:** what counts as direct deposit. Some banks exclude transfers from other banks or payment apps.
- **Deposit deadline:** how many days you have to fund the account or meet the requirement.
- **Holding period:** how long the balance must stay, and whether it is a daily minimum or an average.
- **Payout timing:** when the bonus posts, which can be weeks or months after you qualify.
- **Early closure fee or clawback:** whether closing the account within a set window costs a fee or takes the bonus back.
What to Verify About a 5% APY Account
A headline rate can come with limits that shrink what you actually earn. Check whether 5% applies to your whole balance or only up to a cap, such as the first few thousand dollars. Balances above a cap often earn much less. Look for conditions tied to the rate. Some accounts pay the top APY only with monthly direct deposits, a set number of debit card transactions, or a linked checking account.
Miss a condition and the rate may drop for that month. Confirm the rate is variable or promotional. A promotional rate may last only a few months before falling to a standard rate. Also confirm deposit insurance: FDIC coverage at banks or NCUA coverage at credit unions, generally up to $250,000 per depositor, per institution, per ownership category. For fintech apps, check which partner bank holds the funds.
Taxes, Credit Checks, and Other Hidden Costs
Both bank bonuses and interest are generally taxable income in the US. Banks typically report them on Form 1099-INT or 1099-MISC. That means taxes don't favor either option. Compare them on the same pre-tax or after-tax basis. Opening a checking account may trigger a ChexSystems report or, at some banks, a hard credit inquiry.
A hard pull can lower your credit score slightly for a while, which matters if you plan to apply for a mortgage or car loan soon. Check the bank's disclosures or ask before you apply. Count your time, too. Tracking deposit deadlines, holding periods, and fee waivers across several accounts takes effort. A missed step can turn a $300 bonus into a $0 bonus plus a closing fee.
When to Pick One, the Other, or Both
A bonus usually makes sense when the requirement is direct deposit or a small balance, the holding period is short, and fees are easy to avoid. A 5% savings account usually makes sense for large emergency funds or cash you want to leave alone without deadlines. You don't have to choose just one.
Many people keep their main savings in a high-yield account and route a paycheck to a bonus account only until they qualify. Once the bonus posts and the minimum holding period passes, the money can go back to earning interest. Before closing a bonus account, confirm the bonus has posted and the early closure window has passed. Closing a day early can trigger a fee or a clawback that wipes out the gain.
Frequently Asked Questions
Does a bigger deposit make a bank bonus less worth it?
Often, yes. The more money a bonus ties up in a low-interest account, the more savings interest you give up during the holding period.
Can I earn a bonus on a high-yield savings account?
Some banks offer bonuses on savings accounts that also pay interest. Compare the bonus plus that account's interest against what your current account would earn.
What happens if my rate drops during the holding period?
Variable savings rates can change at any time. Estimate conservatively, especially when you're comparing across six months or more.
Will closing a bonus account hurt my credit?
Closing a deposit account generally doesn't affect your credit score. Early closure can still trigger fees or a bonus clawback under the account terms.
