Best High-Yield Savings Accounts of September 2026: Up to 3.55% APY

Updated September 13, 2026. APYs below were re-verified against each provider’s own rate disclosure on September 6, 2026; the national-average comparison was verified against the FDIC on September 13, 2026.

The short version: Marcus by Goldman Sachs pays 3.50% APY with no conditions attached — no direct deposit requirement, no promotional period that expires, no minimum balance. That makes it the best default for most savers right now. If you’re parking a balance well above $250,000, Wealthfront’s Cash Account trades a tenth of a point for FDIC coverage up to $8 million.

The national average savings rate sits at 0.37% APY according to the FDIC. The accounts below pay roughly nine times that, on money that is insured the same way and carries the same zero risk to principal. Moving cash from a big-bank savings account to one of these takes about ten minutes and is among the highest-return, lowest-effort financial moves available.

Rates are variable and change frequently in a falling-rate environment. Verify the current APY on the provider’s own site before opening an account. This article is information and education, not financial advice.

The accounts compared

*SoFi’s 3.30% APY requires a qualifying direct deposit (any amount) or $5,000 per month in total deposits; new members can earn a promotional boost — advertised in the region of 3.80–4.00% — for a limited period. Without qualifying activity the rate drops to a fraction of a percent. APYs verified against provider disclosures September 6, 2026 and are subject to change at any time.

How we picked — and what we don’t do

We compared 14 nationally available savings accounts from online banks, brokerage cash accounts and large card issuers, and kept the six below. Each was assessed on five things: the APY and — more importantly — the conditions attached to it, the FDIC insurance ceiling, minimum balance and fee schedule, transfer speed and access, and whether the provider has historically held a competitive rate rather than spiking and quietly cutting it.

We do not test bank accounts. Nobody here opened six savings accounts and measured transfer times with a stopwatch, and any site claiming otherwise is worth a second look. Every figure in this article comes from the provider’s own published rate disclosure and fee schedule, or from a named public source — principally the FDIC’s monthly National Rates and Rate Caps, which is where the 0.37% national average comes from. Where a figure could not be confirmed at the source, it is marked with a tilde or a range rather than presented as exact.

Rates in this category move with the federal funds rate, so this page is re-verified monthly and re-dated only when something actually changes.

Our top picks, reviewed

1. Marcus by Goldman Sachs — best unconditional rate

APY: 3.50%  ·  Min. balance for APY: $0  ·  Min. deposit to open: $0  ·  Monthly fee: $0  ·  FDIC: $250,000

Why Marcus? The rate has no conditions attached to it. No direct deposit requirement, no promotional period that expires in six months, no minimum balance, no qualifying activity buried in the disclosure. In a market where the largest advertised numbers increasingly come with the most strings, an unconditional 3.50% is the number you will actually still be earning next year — and that is what moved Marcus to the top of this list. It is a Goldman Sachs product, so the balance sheet behind it is not a question.

Marcus does not offer a checking account, so you link an external bank and transfer money in, typically in one to three business days. For an emergency fund that mild friction is arguably a feature: it puts a speed bump between an impulse and a withdrawal.

What we like

• Unconditional rate — nothing to qualify for or maintain
• No minimum balance and no monthly fee
• Track record of staying near the top of the market rather than spiking and cutting
• Goldman Sachs institutional backing

Watch out for

• No debit card, no ATM access, no checking account — this is not a daily-use account
• External transfers take up to three business days
• FDIC coverage is the standard $250,000, which matters if you’re parking more

Best for: Emergency funds and short-term goals where you want the best reliable rate with nothing to maintain.
Skip it if: You want to spend directly from the account or need same-day access.

Weighing it against the other big online name? Our head-to-head Marcus vs Ally comparison settles it by use case.

2. Wealthfront Cash Account — best for large balances

APY: 3.55%  ·  Min. balance for APY: $1  ·  Min. deposit to open: $1  ·  Monthly fee: $0  ·  FDIC: up to $8 million

Why Wealthfront? The FDIC ceiling. Wealthfront sweeps deposits across a network of partner banks, which lifts coverage to as much as $8 million — against the standard $250,000 at a single institution. If you are holding the proceeds of a house sale, a business exit or a legal settlement while you decide what to do next, that one number is worth more than the tenth of a point you give up against Marcus. Achieving the same coverage manually means opening and tracking dozens of separate bank accounts.

The rate itself is unconditional — no direct deposit required, no minimum beyond a dollar — and applies from the day you fund the account.

What we like

• FDIC coverage up to $8 million through the partner-bank network
• Unconditional rate with a $1 minimum
• Integrates with Wealthfront’s investing side if you use it

Watch out for

• No debit card for the Cash Account — it is a savings vehicle, not a spending account
• Wealthfront is a fintech, not a bank; your money sits at partner banks, so read how the sweep works
• A tenth of a point below Marcus, which costs about $10 a year per $10,000

Best for: Balances above the $250,000 FDIC line, and freelancers without a regular paycheck to qualify elsewhere.
Skip it if: Your balance is comfortably under $250,000 and you simply want the top rate.

3. Ally Online Savings — best full banking ecosystem

APY: 3.00%  ·  Min. balance for APY: $0  ·  Min. deposit to open: $0  ·  Monthly fee: $0  ·  FDIC: $250,000

Why Ally? It is the most complete online bank on this list. Savings, checking, money market and CDs sit under one roof with no monthly fees and 24/7 phone and chat support — which is not a given among online-only banks. The savings account includes Savings Buckets, letting you partition one balance into labelled goals (vacation, car repair, down payment) without opening separate accounts, which in practice is the difference between an emergency fund that survives and one that gets raided.

Ally has also been consistent. It rarely leads a rate spike, and it has not cratered the way promotional-rate banks quietly do once a teaser period ends.

What we like

• Full product suite — you can move your entire banking relationship
• Savings Buckets for goal-based partitioning
• Round-the-clock human support
• Consistent rather than spiky rate history

Watch out for

• 0.40 points behind Marcus on pure yield, about $40 a year per $10,000
• No physical branches if in-person banking matters to you

Best for: Anyone who wants to move their whole banking relationship online, not just park savings.
Skip it if: Maximum yield is your only criterion.

4. Capital One 360 Performance Savings — best for branch access

APY: 3.10%  ·  Min. balance for APY: $0  ·  Min. deposit to open: $0  ·  Monthly fee: $0  ·  FDIC: $250,000

Why Capital One? It is the only account here you can walk into. Capital One operates physical branches and Cafés in a number of US cities, which for some savers is the difference between trusting an online rate and not. Transfers between Capital One accounts are effectively instant, and the account pairs naturally with the company’s checking accounts and cards.

One honest caveat on the rate: Capital One published 3.10% APY on its own 360 Performance Savings page when we read it on 24 September 2026, below several accounts here. Check the live rate on Capital One’s own page before you move money — it is the one number on this page we could not pin to a single value with confidence.

What we like

• Physical branch and Café access — unique on this list
• Instant transfers within the Capital One ecosystem
• No fees, no minimum, no conditions on the rate

Watch out for

• Reported APY varies by source right now — verify before opening
• Capital One has historically run separate “360” products at different rates; make sure you are opening Performance Savings

Best for: Existing Capital One customers, and anyone who wants a branch as a safety net.
Skip it if: You want a rate you can confirm to the basis point today.

5. SoFi Checking & Savings — best promotional rate

APY: 3.30% with eligible direct deposit, promo up to 4.20%  ·  Min. balance for APY: $0  ·  Condition: qualifying direct deposit  ·  Monthly fee: $0  ·  FDIC: up to $2 million

Why SoFi? It advertises the biggest number here. New members can capture a promotional boost in the region of 3.80–4.00% for a limited window, and the bundled checking-and-savings product means one card, one app and instant internal transfers. FDIC coverage runs to $2 million via the partner-bank network, which is well above the standard limit.

The catch is structural. The rate underneath the promo is 3.30%, and it requires a qualifying direct deposit or $5,000 a month in total deposits. Without that activity the rate falls to a fraction of a percent. SoFi topped this list when its with-direct-deposit rate led the market; today it is a promo-and-ecosystem play rather than the default.

What we like

• Highest advertised number on this list for new members
• $2 million FDIC coverage through partner banks
• Bundled checking and savings with instant internal transfers

Watch out for

• The promotional rate expires — put the end date in your calendar
• The rate cliff without a qualifying deposit is severe, not gradual
• Without the qualifying deposit the rate falls well below every other account here

Best for: New members who will actually capture the promo, and existing SoFi users consolidating.
Skip it if: You have no regular direct deposit to qualify with.

If you already use SoFi on the investing side, our SoFi Invest review covers how the two halves fit together.

6. American Express High Yield Savings — best known brand

APY: 3.10%  ·  Min. balance for APY: $0  ·  Min. deposit to open: $0  ·  Monthly fee: $0  ·  FDIC: $250,000

Why American Express? Familiarity, essentially. The rate is the lowest in this group and the product is plain — no checking, no debit card, no notable features. What it has is a brand most people already trust with money, which is a real consideration for savers who are wary of fintechs and partner-bank sweep structures. If you carry an Amex card and want your financial relationships consolidated under names you recognise, it is a perfectly sound account.

What we like

• Established bank brand with no fintech intermediary
• No fees, no minimum, no conditions
• Simple to open if you already hold an Amex card

Watch out for

• Tied with Ally for the lowest rate here — 0.40 points below Marcus, about $40 a year per $10,000
• No checking account or debit card; requires a linked external bank
• No features that distinguish it beyond the brand

Best for: Existing Amex cardholders who value brand familiarity over the last few basis points.
Skip it if: You are optimising for yield at all.

What didn’t make the list

Discover Online Savings. As of September 2026, Discover’s online savings page redirects to Capital One’s Performance Savings product following the two companies’ combination. There is no longer a separate Discover savings account to recommend, so it has been removed from this comparison rather than left in with a stale rate.

Accounts advertising above 4%. A handful of smaller banks, credit unions and fintechs advertise rates above 4% APY. Almost all of them attach one of three conditions: a balance cap (the headline rate applies only to the first $500 or $2,000), a direct-deposit or debit-transaction requirement, or a teaser period measured in months. They can be worth it if you will genuinely meet the condition, but they are not comparable to an unconditional 3.50% and are not listed alongside it here.

Chime, Current and Varo. These are popular, and two of them pay well, but it is worth being precise: Chime and Current are not banks — they are financial technology companies whose deposits are held at partner banks, and FDIC insurance applies through those partners rather than to the fintech itself. Varo does hold a national bank charter. The distinction matters for understanding where your money actually sits and what the insurance covers.

What actually matters when choosing

The conditions matter more than the headline rate

SoFi’s promotional number is the biggest on this page, and it is temporary and conditional. Marcus’s 3.50% has nothing attached. Before moving money, read the rate disclosure specifically for three things: what triggers the advertised APY, when any promotional period ends, and what the rate becomes if a condition is not met. In a falling-rate market, teaser rates are cut first and fastest — the unconditional number is the one you will live with. Balance tiers are the other string to look for: CIT Bank Platinum Savings pays 3.75% APY only when the balance is $5,000 or more, and 0.25% on the entire balance below that, as our CIT Bank Platinum Savings review explains.

FDIC insurance: the standard limit and the elevated ones

Standard FDIC insurance covers $250,000 per depositor, per insured bank, per ownership category. For most savers that is more than enough. Above it, the partner-bank sweep structures matter: Wealthfront’s $8 million and SoFi’s $2 million ceilings are genuinely different from the flat $250,000 at Marcus, Ally, Capital One and Amex. You can replicate the effect manually by spreading money across institutions, but tracking it becomes a job. The FDIC’s own rate and insurance material is the authoritative reference on how the limits apply.

Transfer speed and real access

Every account here is online-only or online-first, and external transfers generally take one to three business days. Capital One moves money instantly within its own ecosystem; SoFi does the same between its checking and savings. If your emergency fund needs to be reachable the same day, either keep a small checking buffer or favour an account whose transfers you have actually tested with a small amount before you rely on it.

“No fee” is not the same as “no cost”

None of these six charge a monthly maintenance fee — that is table stakes now. The costs that remain are wire transfer fees (commonly $15–$25), excess withdrawal fees at institutions that still enforce a monthly transaction limit, and outgoing transfer minimums. Read the fee schedule, not just the rate card.

What a rate difference is actually worth

It is easy to over-optimise. The gap between the best and worst account on this page is 0.40 percentage points, which on $10,000 is about $40 a year — real, but not worth switching banks twice for. The gap between any account here and a big-bank savings account at the 0.37% national average is roughly $300 a year on the same balance. The first move is the one that matters; the rest is fine-tuning. We worked the arithmetic out in full in how much interest $10,000 actually earns.

How much should you keep in one?

The standard guidance is three to six months of essential expenses. If rent, utilities, food and minimum debt payments come to $3,000 a month, that means roughly $9,000 to $18,000. The right end of that range depends on how replaceable your income is: a salaried worker in a deep job market can sit at three months, while a freelancer with lumpy income or a single-income household should lean toward six or beyond.

Once the emergency fund is fully funded, additional cash generally belongs somewhere with a higher expected return, because a savings account is guaranteed to lose to inflation over long periods. For the step-by-step version, read our guide on how to build an emergency fund, including how to automate contributions so it fills itself. Comparing vehicles instead? See the best CD rates right now, high-yield savings vs CDs and money market vs high-yield savings, or where to park $10,000 for the full decision tree.

If you are building the fund and starting to invest at the same time, the order matters — the emergency fund comes first. Our guide to starting to invest with $100 covers the sequence once the cash buffer is in place.

The harder part is usually leaving the money alone. Morgan Housel’s The Psychology of Money is the best-known treatment of why cash you never touch is worth holding even in a year when the rate looks unexciting.

Frequently asked questions

Is the interest taxable?

Yes. Savings interest is taxed as ordinary income at your marginal rate, and your bank reports it to you and the IRS on a 1099-INT once you earn $10 or more in a year. At 3.50% on $10,000 you would owe tax on about $350 of income — roughly $75 in the 22% bracket, leaving about $265 net. If you are self-employed and this account is where your quarterly tax money sits, the bigger number is usually on the other side of the return: see our comparison of the best tax deduction tracking apps.

Can the rate change after I open the account?

Yes, and it will. Savings APYs are variable and move with the federal funds rate — there is no rate lock on a savings account. That is precisely what a CD offers instead, at the cost of access. Banks that pay near the top of the market tend to keep doing so as the absolute number moves, which is why this page tracks the current leaders monthly rather than naming a permanent winner.

How often is interest paid?

Nearly all of these accounts compound daily and credit interest monthly. You will see one deposit land each month, and that deposit immediately begins earning interest itself.

Is my money safe in an online-only bank?

If it is FDIC insured, your deposits are protected to the same $250,000 standard limit as at any brick-and-mortar bank — the insurance does not care whether there is a branch. What to check is whether you are dealing with an insured bank directly or with a fintech that sweeps deposits to partner banks, because in the second case the coverage runs through those partners. Both structures appear on this page, and both are disclosed above.

Should I open more than one?

Usually not for the rate — chasing a tenth of a point across institutions costs more in attention than it returns. There is one good reason to hold more than one: exceeding $250,000 at a single bank. Otherwise, one account you actually leave alone beats three you actively manage.

Do I lose the rate if my balance drops?

Not at any of the six accounts here — none of them requires a minimum balance to earn the advertised APY. That is not universal, though. Tiered accounts elsewhere pay the headline rate only above a threshold, or only on the first slice of your balance, which is one of the main reasons an advertised rate above 4% often is not what it appears.

Bottom line

The choice in September 2026 comes down to Marcus versus Wealthfront: the best unconditional rate, or a tenth of a point less in exchange for FDIC coverage up to $8 million. Ally earns its place for anyone wanting a complete banking relationship rather than a parking spot. Capital One suits people who want a branch. SoFi is a promotional play for members who will meet its conditions, and Amex is the familiar-brand option at the cost of the lowest rate here.

All six beat a traditional savings account by a wide margin. If your money is sitting at the 0.37% national average, moving it to any account on this page is worth the ten minutes it takes — and in a falling-rate year, locking in today’s rate on money you genuinely will not touch is exactly what CDs are for.
