Why you might not earn that advertised savings APY

A practical guide to balance requirements, promotional rates and qualification rules, with steps to check the offer before opening an account and verify what you earn afterward.

Imagine comparing two savings accounts, one advertising 5% and another advertising 4%. You start with the higher rate, work out what it could earn on your savings, and click through to the application. Then the details begin to change the calculation. The 5% might apply only to the first $1,000, expire after a few months, or require you to leave several thousand dollars in a checking account that earns very little. Once you account for the rest of your money, the 4% account may leave you with more interest.

The difficulty is that those details may be scattered across the product page, a separate promotion and the account disclosures you encounter while applying. You can get quite far into opening an account before you have enough information to compare it properly. If the first time you put everything together is when the interest appears on your statement, you may already have moved your savings and redirected your paycheck.

I would bring that work forward, while choosing a different account is still easy. A qualifying deposit that arrives through your normal payroll may take little effort. A rate that depends on keeping extra money elsewhere or remembering a monthly list of transactions needs a closer look. Before committing, you should be able to follow your money through the offer: which dollars earn the advertised rate, what you must do to qualify, and what you will earn if your plans change.

Start with the exact account and save the terms

Start with HYSA's savings-account comparison tool. Enter the balance you expect to keep, select accounts to compare, and open their full key conditions and offer details. That gives you a place to examine the recorded balance requirements, fees, promotional terms and qualification rules alongside the headline APYs. Check the verification dates and any information marked unconfirmed. The interest estimates assume qualification and are before fees and taxes, so treat them as a starting point for your own calculation.

Compare savings accounts and examine their terms →

For an account you are seriously considering, follow through to the institution's own product page, rate sheet, account disclosures, fee schedule and any separate promotional terms. Match the exact product name across them. A bank can offer several similarly named savings accounts, and an advertisement for a new product does not establish the rate on an older account you already own. Confirm the terms that apply to you directly with the institution before opening.

Save dated copies or PDFs of the offer, its footnotes and the documents that apply to your application. Include the page address and any invitation or promotional code. A screenshot of the headline alone leaves out most of what you may need later. Keep these records privately, separate from anything you post in a public banking discussion.

Use the page's search function for terms such as “qualify,” “minimum,” “average daily,” “up to,” “new money,” “direct deposit,” “relationship,” “promotion,” “statement cycle” and “fees.” Then read the surrounding sections. Search helps locate conditions; it will not tell you whether two requirements must be met together.

U.S. bank account disclosures address rates, compounding, balance requirements and fees. The minimum to open an account, the balance needed to avoid a fee and the balance needed to obtain an APY can be different amounts. Write down all three, along with how each is measured.

Work through the offer before you apply

With the account details in front of you, use the following 13 checks to work out what you would actually receive. An offer can combine several of these conditions, so keep going after you find the first one. For each requirement that applies, record what you need to do, when you need to do it and the rate or cost if you miss it. A conditional offer can still be worthwhile; this process should tell you whether it fits the way you will use the account.

1. The attractive rate starts above a balance you cannot maintain

A small opening deposit does not necessarily qualify you for the advertised yield. A higher tier might require thousands more, tested against a daily balance or an average over a specified period. With a whole-balance tier, dropping below the threshold can change the rate applied to all the money in the account.

Check the offer at three balances: what you will deposit, what will remain after a likely withdrawal, and what you expect to hold later. Ask whether interest credited to the account counts toward the threshold and when a balance change affects the rate. If the account works only while your emergency fund remains untouched, include the lower-rate outcome in your decision. Needing your savings should not come as a surprise to the comparison.

2. The attractive rate stops after a small slice of your savings

“Up to” can conceal a ceiling on the dollars earning the top rate. A hypothetical account paying 5% on the first $1,000 and 1% on the remaining $9,000 produces about $140 on a $10,000 starting balance over a year, not $500. A flat 4% account would produce $400 under unchanged full-year assumptions. The tiered figure is a screening estimate; actual compounding and the treatment of interest crossing the cap affect the result.

Find the rate above the cap, and determine whether the cap applies per account, per owner or across a banking relationship. Also check whether crossing an upper balance limit removes a promotion entirely. “Only the excess earns less” and “the whole account loses eligibility” have very different consequences.

Use the institution's actual calculation method before making a final comparison. Our tiered-APY guide works through the distinction between separate balance slices and a rate selected for the whole balance.

3. You must leave money in another account to qualify

A relationship rate can require checking deposits, a continuing checking balance, or other eligible assets. That money belongs in the calculation even when the savings advertisement leaves it outside the frame. A requirement involving investments also deserves its own review of fees, access and risk; a savings-rate boost is a poor reason to make an investment you would otherwise avoid.

For a hypothetical example, suppose 5% APY on $10,000 in savings requires another $5,000 in checking at 0%. Over a full year with unchanged rates, retained interest and no fees, the two accounts earn $500 on $15,000, a combined return of about 3.33%. If all $15,000 could instead earn 4%, it would earn $600. This combined-return calculation is a household comparison, not the bank's disclosed savings APY.

There is a practical qualification here: you may need some checking money anyway. Compare realistic arrangements. If you already keep $2,000 in checking to pay bills, identify the additional $3,000 tied up by the offer and what that money would otherwise earn. Do not assume your entire checking balance is available to move into savings.

These requirements occur in actual offers. Axos ONE terms reviewed for this guide tied boosted savings interest to qualifying deposits and an average daily balance in its checking account. Before opening a bundle, get a written list of every required account, balance test and fee, then price the bundle at your own balances.

4. Your deposits do not count as qualifying direct deposits

Payroll, pension or government-benefit deposits may count under an offer's definition while transfers from your own bank, payment apps or deposited checks do not. A rule about a monthly deposit total is also different from one requiring a particular kind of income. Read the definition and the exclusions before redirecting anything.

Confirm which account must receive the money, the required amount and the measurement period. If you are changing payroll instructions, ask your employer when the change will take effect. Leave time for the first deposit to arrive and verify that the bank recognized it as qualifying. An instruction submitted to payroll is not evidence that the bank received an eligible deposit.

Varo's qualification guidance illustrates the distinction: it identifies eligible income deposits, excludes other payment types and explains how to check deposit recognition. It also bases the elevated savings rate on the prior month's qualifying activity. If your income is irregular, compare the account using the rate you would receive in months when you miss the requirement.

5. You must keep adding money or completing transactions

An account may require recurring deposits, net balance growth, debit-card purchases, bill payments or other activity. A requirement for fresh deposits does not necessarily require payroll, and a requirement for balance growth is not satisfied merely by moving the same money out and back. Check the offer's treatment of withdrawals, refunds, internal transfers and returned payments.

For purchase requirements, record the count, any minimum amount and which transactions are excluded. Find out whether purchases must post and settle by the deadline. A pending purchase on the final evening may be too late. Kasasa's materials explain that qualifications and cycle dates vary by institution; use the specific bank or credit union's disclosure rather than another customer's description.

Count the activity you already do. If you would need extra purchases to qualify, subtract that spending from the benefit. If you would move normal spending from a card that earns rewards, allow for the rewards you would give up. I would not buy things I do not need to earn more interest on the money I am trying to save.

6. A setup step or paid membership controls the rate

Electronic statements, online-banking enrollment, required logins or a separate rate-program opt-in can be part of qualification. Check these settings after opening and save the enrollment confirmation. Do not assume creating an online login also enrolls you in every relevant program.

A subscription creates a separate calculation. Suppose a hypothetical $10 monthly membership buys an extra 0.50 percentage points on your savings. On $10,000, that improvement is about $50 over a full year before the $120 subscription cost and taxes, assuming unchanged APYs and balance. An uncapped balance of about $24,000 would be needed just to cover that fee before taxes. A cap below that amount could prevent the interest alone from covering the cost at all.

Check for a qualifying route without a subscription, and give other membership benefits only the value they have to you. SoFi's terms, for example, distinguish paid membership from deposit-based qualification and explain what happens when a subscription ends. Record the renewal date, cancellation cutoff and rate afterward before relying on a trial or paid boost.

7. The promotion ends before your savings plan does

An introductory rate can last for days, calendar months or statement cycles. Find both the deadline to enroll and the date your own benefit ends. Those are separate clocks. Check whether the offer starts when you apply, when the account opens, when you fund it or when you first qualify. Delaying a deposit may leave less time to earn the promotion.

Compare the promotional period and the period afterward separately. Do not multiply a short-term headline by your balance and call the result a year's earnings. For a hypothetical $10,000 balance, APY-equivalent growth at 5% for 90 days and 2% for the next 275 days produces about $273 over a 365-day year with retained interest. A constant 4% produces $400. This is a planning illustration, not an advertised composite APY or a prediction of future rates.

Also distinguish a guaranteed total rate from a fixed boost added to a variable base. If only the boost is fixed, the total can fall during the promotion. Calendar a review before the benefit expires, leaving enough time to consider transfer limits and any remaining holding requirements.

8. A referral link, code or invitation is part of the offer

Some offers require a particular application link, a code entered before submission or an invitation addressed to you. Others reward successful referrals after you become a customer. Do not build a long-term interest estimate around recruiting people who have not agreed to open accounts.

Before applying, verify that the offer appears in the application and save its confirmation. If you leave and restart, check whether you must return through the original link. Marcus's referral terms, for example, specify the application route and state that a new account opened without the required referral link will not receive the referral boost. They also describe ownership restrictions and referral limits.

Check whether additional referrals increase the rate, extend the duration or do neither beyond a limit. Confirm whether the promotion combines with other offers. A bank's ordinary application may be perfectly functional while failing to enroll you in the benefit you wanted.

9. “New customer” or “new money” excludes you

New-customer rules may look back at closed accounts, apply across related brands or test more than one owner of a joint account. New-money rules may exclude transfers from other accounts at the institution or measure your increase over a prior relationship balance. Opening another account does not necessarily make either you or the money new.

Before submitting the application, ask whether your prior accounts, joint ownership and proposed funding source qualify. Give the relevant facts through a secure bank channel and request a written response identifying the applicable offer. If you already hold an account, ask whether moving to the advertised product requires a conversion or a new application, and whether doing so would affect eligibility.

10. Your location or opening method changes the offer

A national-looking advertisement can lead to terms that depend on your ZIP code, membership eligibility or the channel through which you apply. A branch, an online application and a partner invitation can carry different conditions. Credit-union membership can also involve a separate membership share or joining requirement.

Get the quote using your actual address and intended ownership type. Confirm individual versus joint eligibility and any restriction on trusts or business accounts. If joining requires a payment or a balance in a separate share account, include it in the cost and cash commitment. Save the final application disclosures, especially when they differ from the page that first caught your attention.

11. The qualification calendar works differently from yours

A calendar month, statement cycle and qualifying period can end on different dates. An offer may stop counting activity before month-end, apply this month's qualification to next month's interest, or treat the first partial cycle differently. Opening near a cutoff can reduce the number of promotional cycles you receive.

Put the dates in your calendar before funding: opening deadline, funding deadline, recurring qualification cutoff, first eligible interest period, promotional expiration and any required holding-period end. Include the stated time zone. Schedule routine deposits or payments with room for weekends, holidays and posting delays rather than aiming for the final day.

Use a bank's qualification tracker when available, but check what it measures. Save evidence of completed activity and the rate status. If a tracker disagrees with your records, ask while there is still time to correct the issue. Check the fallback rate and whether a missed month affects only that cycle, the next cycle or continued promotional eligibility.

12. Fees and exit conditions reduce the benefit

APY does not tell you what remains after all the costs of your arrangement. Review maintenance fees, membership charges, transfer fees and waivers you could lose at your current bank after moving money. Include every required companion account in that review.

Separate conditions for earning ordinary interest from those attached to a promotional payment. A cash bonus may require keeping the account open after the deposit period and may be recoverable if you close early. Check for an early-closure fee and whether closing before a crediting date forfeits accrued interest. Get the applicable dates and amounts rather than assuming all incentives follow the same rules.

Before moving, test the withdrawal route you intend to use and understand its limits. Keep upcoming bill money accessible. If the offer needs money you will probably withdraw during its holding period, calculate the consequences of that withdrawal now.

13. The advertised rate changes, or describes a different kind of return

A variable savings rate can change after you open the account. Regulation DD has an exception to its advance-notice rule for changes in rates and corresponding APYs on variable-rate accounts. Do not count on a warning before every rate reduction. Review the rate on your own account periodically, particularly after a promotion or a change in your qualification status.

CFPB: subsequent disclosures and the variable-rate notice exception ↗

Keep ordinary interest, temporary boosts and one-time cash bonuses separate. Do not add a sign-up bonus to APY as though it repeats each year. Check the date on a comparison page or search result, then verify the current terms directly with the institution. An old offer can remain easy to find long after it stops being available.

Also confirm that you are comparing bank deposits. A brokerage money market fund's seven-day yield, a projected investment return and a savings APY are different measures attached to different products. Verify where the money is held and how you can access it before treating the percentage as comparable.

Before applying, put the offer through a bad month

Write a short offer summary in your own words: “I will keep this much in savings and this much in required companion accounts. These deposits and actions qualify me. This amount earns the top rate until this date. The rest earns this rate. If I miss a requirement, this is what happens.” Fill every gap from the disclosures or a written answer before relying on the offer.

Then calculate three outcomes: you qualify throughout the period; you miss a requirement for a cycle; and the promotion ends while you still hold the money. For each, total the estimated interest across required accounts and subtract applicable costs. Compare those dollars with a simpler account over the same period. Add a cash bonus separately only when you have checked its eligibility, timing and conditions.

For a single constant APY, a useful planning estimate is balance multiplied by [(1 + APY as a decimal) raised to (days divided by 365), minus 1]. It assumes retained interest and APY-equivalent daily growth. It is not the bank's ledger calculation. Tiers, changing balances, qualification delays and actual crediting rules require adjustments; ask the bank for an explanation at your planned balance if its schedule is unclear.

Consider a month with a delayed paycheck, a necessary withdrawal or less card spending. If the advantage disappears under an ordinary interruption, decide whether the extra monitoring is worth the best-case benefit. I would rather choose an account whose requirements fit my routine than make the interest depend on remembering a routine I do not otherwise need.

After opening, verify that the account is doing what you expected

First, check the product name, offer enrollment, statement settings and qualification status in your account. Confirm that the first qualifying deposit was recognized and note the date the higher rate should begin. Keep the original disclosures alongside these confirmations so a later website change does not erase your reference point.

Next, review the first statement that covers a fully eligible period. Find the interest earned, the APY earned for the statement period, any fees and the period's dates. A current rate displayed in the app may describe a different period from the one on the statement. A partial first month, changing daily balances or a delayed qualification date can explain a smaller payment. Comparing the credit with one-twelfth of a headline annual amount is not enough to establish an error.

CFPB: periodic statements, interest earned and fees ↗

If the result still does not make sense, send a secure message identifying the offer, the period in question and the requirements you believe you met. Ask which rate was applied, which balance and dates were used, and which specific condition the bank considers unmet. Attach the relevant confirmation or statement through its secure channel, request a case number, and ask when to expect a response. A written explanation gives you something more useful than another reading of the advertisement.

If the bank has not resolved a suspected error or misleading offer, consider submitting a complaint to the CFPB or contacting the institution's appropriate regulator. Keep a concise timeline and copies of your evidence. A complaint does not guarantee a correction or suspend other deadlines. Do not put account numbers, statements or identity documents in public comments while seeking help.

CFPB: submit a consumer complaint ↗

Once the first eligible statement checks out, keep the recurring reminders that the account actually requires and a review date before any promotion ends. If the return is lower than expected, establish whether the cause is a bank error, a missed condition or an offer that no longer fits. Resolve outstanding payments and exit conditions before moving again. The next account should earn its place with a calculation you can verify on a statement.
