Discover Online Savings review (2026): what existing customers should know after the Capital One merger

This is not a typical bank review. Discover Online Savings was, for years, one of the most straightforward high-yield savings accounts in the United States — no fees, competitive APY, solid FDIC insurance, and 24/7 customer support with a Spanish-language option. But the landscape changed permanently in May 2025 when Capital One completed its acquisition of Discover Financial Services, and again in January 2026 when Discover stopped accepting new deposit account applications entirely.

If you are reading this because you searched for a Discover savings account review, here is the most important thing we can tell you: you cannot open a new Discover Online Savings account. The application is closed. If you already have one, your account is in the process of migrating to Capital One 360 Performance Savings. This review is written for existing Discover customers who want to understand what is happening to their money — and whether they should stay through the transition or move it somewhere else.

What Discover Online Savings pays right now

As of April 2026, existing Discover Online Savings accounts earn 3.30% APY. There is no minimum balance requirement to earn this rate, no monthly fee, and no opening deposit minimum (though that last point is now moot since you cannot open a new account). Interest compounds daily and credits monthly.

• 3.30% APY on all balances. No tiers, no conditions.
• No monthly maintenance fee.
• Daily compounding, monthly crediting.
• FDIC insured — certificate #5649 (Discover Bank, Member FDIC). Note: since both Discover Bank and Capital One, N.A. are now under the same ownership, FDIC coverage limits may apply jointly if you hold accounts at both institutions.
• 24/7 phone support with Spanish-language option still available during the transition.

The merger timeline: what happened and what is coming

Capital One announced its intent to acquire Discover Financial Services in February 2024. The deal closed on May 18, 2025, making Discover a wholly-owned subsidiary of Capital One. For several months after the close, Discover deposit products continued operating under the Discover brand. Then, in late January 2026, Discover stopped accepting new applications for savings and checking accounts. The next step — and the one that will affect your day-to-day experience — is the full account migration to Capital One systems.

When the migration completes, your Discover Online Savings account will become a Capital One 360 Performance Savings account. Capital One has stated that account numbers may change, but your money, your balance, and your FDIC insurance will carry over. The 360 Performance Savings currently pays 3.20% APY — 10 basis points less than the current Discover rate. Whether Capital One will harmonize the rates before, during, or after migration is not yet clear.

What existing Discover customers should do

If you are happy with your Discover savings account and do not need to do anything complicated, the simplest path is to wait. Your money is FDIC insured. The transition to Capital One is being handled automatically. You do not need to close your account and reopen one — Capital One will convert it for you. Your login credentials will change at some point, but Discover and Capital One have committed to communicating the timeline well in advance.

However, there are a few situations where you should consider moving your money before the migration:

1. You already have a Capital One savings account. After the merger, both accounts fall under the same FDIC certificate. If your combined balance at Capital One exceeds $250,000 per ownership category, the excess is uninsured. Check your total exposure.
2. You care about the rate and 3.20-3.30% is not competitive enough. As of April 2026, several FDIC-insured HYSAs pay significantly more: Varo (5.00% on qualifying balances), BrioDirect (4.85%), Bask Bank (4.65%), UFB Direct (4.57%). If you have been with Discover out of inertia and the rate matters to you, this transition is a natural moment to shop around.
3. Spanish-language support is critical to you. Discover has offered strong Spanish phone support for years. Capital One also offers Spanish support and has an app with a Spanish language setting, so this should carry over — but the quality and wait times during transition are unpredictable. If Spanish support is non-negotiable, verify the experience after migration before committing long-term.

Discover vs the current HYSA market

At 3.30% APY, Discover sits in the lower half of the 18 accounts we track. It is 10 basis points above Ally and Capital One (both at 3.20%) but well below the market leaders. On a $25,000 balance, the difference between Discover's 3.30% and BrioDirect's 4.85% is approximately $387 per year. That is real money.

What Discover still has going for it — at least through the transition — is the combination of a clean no-fee structure, daily compounding, an established customer service operation, and Spanish phone support. For existing customers who value those things and have balances under the FDIC limit, staying put through the migration is a reasonable choice. But if you are evaluating Discover against a fresh HYSA opening, the comparison is moot: you cannot open a Discover account. Look at Capital One 360 Performance Savings (our review), Ally (our review), SoFi, or one of the higher-rate options on our comparison page.

The FDIC insurance question

Discover Bank's FDIC certificate number is #5649. Capital One, N.A.'s certificate is #4297. As of the merger close, both entities are under the same corporate umbrella. The FDIC has a six-month grace period rule: for six months after a merger, deposits at the acquired bank are separately insured from deposits at the acquiring bank, even though they are now one institution. After that grace period expires, the combined deposits are insured under the surviving bank's certificate.

In plain English: if you have $200,000 at Discover and $200,000 at Capital One in the same ownership category, you are fine during the grace period ($250K coverage at each). After the grace period, your combined $400,000 is insured up to $250,000 — the remaining $150,000 is uninsured. If this applies to you, act before the grace period ends.

FAQ

Can I still open a Discover savings account?

No. Discover stopped accepting new deposit account applications in late January 2026 as part of the Capital One merger integration. If you want an account with similar features, Capital One 360 Performance Savings is the closest option at the same parent company.

Will my Discover savings rate change?

Possibly. Discover currently pays 3.30% APY and Capital One 360 Performance Savings pays 3.20% APY. When your account migrates, the rate will likely align with Capital One's current offering. The difference is 10 basis points ($10/year per $10,000), which is small but worth noting.

Is my money safe during the transition?

Yes. Your deposits remain FDIC insured throughout the merger and account migration. Discover Bank (FDIC certificate #5649) is a Member FDIC institution. After full migration, your coverage falls under Capital One, N.A. (FDIC certificate #4297). The only risk is if your combined deposits at both institutions exceed the $250,000 FDIC limit per ownership category after the grace period.

Should I move my money to a higher-rate HYSA?

That depends on your priorities. If maximizing APY is your goal, several options pay 100-170 basis points more than Discover right now — BrioDirect (4.85%), Bask Bank (4.65%), Varo (5.00% with conditions). If you value the no-hassle transition and plan to stay in the Capital One ecosystem, waiting is perfectly reasonable. The merger is not a reason to panic, but it is a natural moment to evaluate whether your savings are working as hard as they could be.

Does Discover still offer Spanish-language support?

As of April 2026, yes — Discover's 24/7 phone line still offers a Spanish-language option. Capital One also provides Spanish phone support and a Spanish app setting. We expect Spanish support to continue after the full migration, but recommend verifying directly with Capital One if this is a deciding factor for you.
