The high-yield savings account is one of the few corners of consumer finance where the basic shopping math is straightforward. Find an FDIC-insured account with a competitive yield and reasonable terms, deposit your cash, watch the interest accumulate. The complications are mostly in the terms — minimum balances, conditional rate tiers, transfer restrictions, fees that the marketing page does not feature — and in the slow drift of yields as each bank adjusts its rate to its own competitive logic.

We tracked five widely available high-yield savings accounts over the last six months and tested account-management workflows in two staff households. The headline finding is that the relative ranking of yields among the major HYSA brands has been more stable in 2026 than in some recent years, but that small differences in yield are still a less important shopping variable than account terms and customer-service responsiveness.

#1 Marcus by Goldman Sachs — Top pick

APY at writing: 4.50% (variable). Minimum balance: $0. Fees: none.

The Marcus Online Savings Account remains the most consistent pick in this category. The yield has been competitive across the six-month tracking window — slightly behind the leaders at some points, slightly ahead at others, but never far off the top of the field. The account terms are clean: no minimum balance, no fees, no tier conditions, no monthly maintenance charges.

Customer service has been responsive across our testing. We submitted a formal account-restriction inquiry as part of testing and received substantive replies within 24 hours each time. The mobile app is functional but not particularly polished; the desktop web experience is also functional but feels designed in 2018.

The notable absence is a checking account companion. Marcus does not offer a checking account, so a Marcus user must move money to and from an external bank. For most users this is fine — same-day ACH transfers cover the case — but for users who want a unified bank-and-savings experience, the absence is real.

This is the easy pick if you want a straightforward high-yield savings account.

#2 SoFi Money

APY at writing: 4.40% (with direct deposit) / 1.20% (without). Minimum balance: $0. Fees: none.

SoFi Money pairs a checking account with a savings account in a single product, with the high APY conditioned on the user setting up direct deposit through the account. For users who can use SoFi as their primary bank — receive their paycheck there, pay bills from there — the headline APY is competitive and the integration is genuinely useful.

For users who want only a savings account, SoFi is a worse choice than Marcus. The conditional APY is the catch: without direct deposit, the savings yield drops to about 1.20%, which is essentially a punishment for treating the account as savings only.

SoFi has expanded its broader product suite considerably over the last few years, and users who can take advantage of the integrated investment, loan, and credit-card products may find the bank’s overall ecosystem useful. For users who just want to park cash, the simpler Marcus account is the better answer.

#3 Ally Bank Online Savings

APY at writing: 4.35% (variable). Minimum balance: $0. Fees: none.

Ally has been a competent and consistent online bank for more than a decade, and the savings account is a perfectly serviceable choice. The mobile app is the most polished in this list, the customer service is reliable, and the bank’s broader product suite (checking, CDs, brokerage) is fully integrated.

The yield has been a little behind Marcus across the six-month tracking window — not by enough to matter for small balances, but the difference is real. For users who already bank with Ally for other products, the savings account is a sensible companion. For users opening a new account from scratch, Marcus’s slightly higher yield and equally good terms make it the slightly better choice.

#4 Capital One 360 Performance Savings

APY at writing: 4.25% (variable). Minimum balance: $0. Fees: none.

Capital One 360 is the option for readers who specifically want a high-yield account at a bank with physical branches. Capital One’s rate has been a step behind the leaders across our tracking, but the bank’s branch network and integration with Capital One credit card products will matter to some users.

If branch access matters and you want a competent high-yield account, this is a reasonable answer. If branch access does not matter, Marcus and Ally are paying meaningfully more.

#5 American Express High Yield Savings

APY at writing: 4.30% (variable). Minimum balance: $0. Fees: none.

The American Express HYSA is well-administered and tightly integrated with Amex’s existing credit-card account infrastructure. For Amex card users, the account-management experience is unusually clean — same login, same app, same customer-service routing.

The yield has been a step behind Marcus and Ally across the tracking window, and the user experience for non-Amex-card customers is somewhat clumsier (more verification steps at signup, less integration with general banking workflows).

This is a reasonable option for existing Amex card members. For everyone else, prefer Marcus or Ally.

What about the headline-rate accounts?

A handful of accounts in 2026 advertise APYs of 5.00% or higher — well above the rates in this roundup. These accounts almost always come with material restrictions: maximum balance caps (the rate applies only to the first $10,000 or $25,000), conditional minimum direct-deposit requirements, or various other tier-and-bonus structures.

For some users with the right account-flow patterns, these accounts can produce a real yield advantage. For most users, the friction of meeting the conditions exceeds the yield difference, and a simpler account at a slightly lower rate is the better choice. We have generally avoided featuring these accounts in our roundups for that reason.

What to actually do

For most readers: Marcus by Goldman Sachs. If you can use SoFi as your primary bank: SoFi Money. If branch access matters: Capital One 360. If you want a polished mobile experience and you do not mind a slightly lower yield: Ally Bank.

The yields will move over the year. The relative rankings will shuffle. The basic posture — keep cash in an FDIC-insured high-yield account at a major online bank, do not chase the headline-rate promotional accounts unless their conditions match your account flow — should hold up.
