Yes, you can claim a $400 opening bonus on a new savings account today. As of July 2026, several major banks and financial institutions are actively offering $400 sign-up bonuses paired with competitive annual percentage yields, making this a legitimate way to boost your savings with fresh money or transfers. The catch is that these offers come with specific requirements—minimum deposits, promo codes, balance maintenance periods, and expiration dates—that vary significantly from bank to bank.
The current market shows $400 is actually in the middle range of what banks offer. While some institutions push bonuses up to $3,000, the $400 tier has become a common standard for savings and money market accounts because it rewards moderate deposits without requiring massive capital commitments. The actual value of each offer depends less on the bonus amount itself and more on the combination of that bonus, the APY rate attached to it, and how realistic the account requirements are for your financial situation.

Which Banks Currently Offer $400 Bonuses on High-Yield Savings Accounts?
E*TRADE’s Premium savings Account stands out as a direct play for the $400 bonus. You get the full $400 when you enter promo code SAVING26 at account opening, deposit at least $20,000 within 30 days, and maintain that balance for an additional 45 days after the deposit arrives. The account itself earns 4.00% APY for the first six months, which was strong relative to typical savings rates earlier in 2026. The offer expires September 30, 2026, so if you’re reading this close to that date, timing matters. SoFi takes a tiered approach rather than a flat $400 for everyone. If you set up direct deposits of $1,000 to $4,999.99, you get a $50 bonus.
Push that direct deposit to $5,000 or higher and the bonus jumps to $400. This structure rewards people who are actually moving meaningful income into the account, not just parking a single large deposit. The SoFi offer runs through December 31, 2026, giving you more runway than E*TRADE. Cambridge Savings Bank’s $400 bonus applies to their Relationship High-Yield Money Market account (not a savings account in the traditional sense, but similar function). This one requires a $25,000 minimum average monthly balance maintained for three full months. The offer window is May 1 through September 30, 2026, meaning if you’re reading this after that date, this specific offer will have expired.
What Makes These $400 Bonus Offers Competitive in Today’s High-Yield Savings Market?
The headline number—$400—means almost nothing without context. What matters is the relationship between the bonus, the APY you’re actually earning, and what you have to do to claim it. E*TRADE’s 4.00% APY is legitimate, but it’s only guaranteed for six months. After that period ends, the rate could drop, and you’d be left with a standard savings account offering. Check the fine print on what the APY becomes after the promotional period. The broader market context helps here. In July 2026, high-yield savings accounts typically offer APY rates between 4% and 5%, with some institutions pushing slightly higher for certain account tiers.
A $400 bonus on top of that APY is meaningful—that’s essentially free money—but it’s not unusually generous. Some banks push bonuses to $1,000 or beyond, particularly for checking accounts or when you maintain very large minimum balances. The $400 offers are positioned as accessible entry points that don’t require six-figure deposits. One important limitation: a $400 bonus on a $20,000 deposit equals just 2% of your deposited capital. If you’re earning 4.5% APY on that same deposit, you’re getting more money from the interest than from the bonus within the first year. The bonus is nice, but don’t let it overshadow the actual APY rate the account pays. An account with a $400 bonus and 3.5% APY might be a worse deal than an account with no bonus but 4.8% APY, depending on how long you’re keeping the money there.
How Do Deposit Requirements and Balance Maintenance Rules Affect the Real Value?
E*TRADE requires the full $20,000 deposit within 30 days of opening the account. If you don’t have that capital available, you can’t claim the bonus—there’s no halfway option. Plus, you need to keep the account at or above that $20,000 balance for 45 days after the deposit clears. For a 75-day total commitment (30 days to deposit plus 45 days to maintain), you’re locking up at least $20,000. If you were planning to save that money anyway, this is fine. If you’d normally keep it in a checking account or money market fund, moving it specifically to grab a bonus and then withdrawing it defeats the purpose. SoFi’s direct deposit requirement is perhaps the most practical filter. You need consistent deposits hitting your account—not a one-time transfer, but recurring payroll or income.
This is intentional on SoFi’s part: they want to see you actually using the account, not just parking money. The upside is that if direct deposit is already part of your routine, you satisfy the requirement naturally. The downside is that if you’re self-employed or paid irregularly, meeting the $5,000 deposit threshold might require bundling multiple payments together. Cambridge Savings Bank’s requirement is brutal if you don’t have $25,000 sitting idle or available to move. You have to maintain that as an average balance for three consecutive months. A single month where your balance dips below $25,000 could disqualify you. This isn’t a deposit-and-maintain situation like E*TRADE; it’s a rolling average that requires discipline. For someone with a typical emergency fund, this might mean basically freezing a quarter of your liquid savings for a quarter of a year.
Comparing APY Rates, Deposit Minimums, and Timeline Across the Three Offers
Let’s put these side by side for someone with $25,000 available to deposit. E*TRADE gives you $400 plus 4.00% APY on that $25,000 for six months, then the rate adjusts. In dollar terms, six months at 4% on $25,000 is roughly $500 in interest, so you’re looking at a combined benefit of $900 over that promotional period. SoFi, if you can trigger the $400 bonus through direct deposit, pays you the $400 plus whatever APY they’re currently offering on the balance (which you’d need to check their current website for). Cambridge Savings pays $400 plus their high-yield money market rate, also variable. The real tradeoff is flexibility versus reward. E*TRADE locks you in with a specific code and a specific deposit window. SoFi requires the direct deposit mechanism but is less stringent about the total amount.
Cambridge requires the highest balance but might offer a higher APY on that balance if you’re carrying it long-term. If you have $20,000 and only that much, E*TRADE is your path. If you have $25,000 and can keep it there, Cambridge might pay more in total interest. If you’re moving payroll deposits anyway, SoFi is the path of least friction. One major comparison point: promotional APY rates expire. E*TRADE drops after six months. You don’t know what your new rate will be until you call or log in. Before opening any account for the bonus, ask about the post-promotional rate and whether it’s competitive with what other banks offer. A 3.2% APY after the promotion isn’t a deal-breaker if you’re committed to the account long-term, but it’s essential information.
What Are the Common Mistakes People Make When Claiming a $400 Bonus?
The single biggest mistake is opening an account, claiming the bonus, and immediately withdrawing all the money. Most of these offers have explicit language about maintaining the deposit for a set period. E*TRADE requires 45 days of maintenance after the deposit clears. If you withdraw on day 44, you lose the bonus. The institution will claw back the $400 from your account balance or simply refuse to credit it in the first place. Read the full terms before you open the account, not after. A second mistake is misunderstanding promo codes. E*TRADE requires code SAVING26 at account opening.
If you open the account without entering the code, no bonus applies, and you may not be able to retroactively add it. This is user error, not the bank’s fault, but it happens frequently enough that it’s worth checking three times before submitting the application. Some banks also limit the code to new customers only—if you’ve ever had an E*TRADE savings account, you might be ineligible. A third mistake is forgetting about expiration dates and missing the window. Cambridge’s May 1 through September 30 window is now closed if you’re reading this after late September 2026. SoFi’s December 31, 2026 deadline might feel far away in January 2026, but banking moves slowly. It can take five to ten business days for a new account to be fully activated and ready to receive deposits. Wait too long and you’ll miss the deadline. Mark the date on your calendar.
How to Choose the Right $400 Bonus Savings Account for Your Financial Situation
If you have a steady paycheck and flexibility on how you distribute it, SoFi’s direct deposit requirement is actually an asset. You’re not stretching to meet a deposit minimum; direct deposits are already happening. The $400 bonus essentially pays for a nice lunch and leaves you with a high-yield account. The fact that you don’t have to lock in a specific large deposit makes this accessible even if your liquid savings are modest. If you have a lump sum of cash sitting in a regular savings account earning nothing, E*TRADE’s Premium Savings offers a faster path to the bonus.
You need just one deposit of $20,000, you wait 45 days, and the money is yours to deploy however you want after that. The four percent APY for six months also gives you a concrete rate you can calculate against. Just confirm that their post-promotional rate won’t be a downgrade you can’t live with. Cambridge Savings is the choice only if you have $25,000 of liquid capital you genuinely won’t need for three months and you want the highest possible yield during that window. The money market account might offer a higher APY than their savings products, making the total return superior to the other options even though the process is more restrictive. Call Cambridge directly and ask what the current money market APY is before committing.
When Will You Actually Receive Your $400 Bonus After Opening the Account?
E*TRADE credits the $400 bonus in your account after the balance maintenance period ends—so 45 days after your qualifying deposit clears. You’ll see it as a line item in your account activity. From the moment you open the account, you’re looking at roughly 75 days until the money is available: 30 days to deposit plus 45 days to maintain. SoFi processes the bonus sometime after you’ve hit the direct deposit threshold. You need to confirm with SoFi when that window resets, but typically it’s within a billing cycle or two of when the qualifying deposit hits.
Plan for 30 to 60 days from account opening to bonus posting. Cambridge Savings credits the $400 after the three-month maintenance period ends. If you open the account on May 15, your three-month window is May 15 through August 15. You’d see the $400 credit sometime in late August, pending their internal processing timeline. These banks don’t post bonuses instantly; there’s always a lag built in to confirm you didn’t violate the terms and are eligible.
