eToro Cash ISA Review: Is 4.78% Too Good to Be True?

eToro is best known as an investment and trading platform, but its Cash ISA has quietly become one of the most competitive savings products in the UK market. For the 2026/27 financial year, it's offering 4.80% AER (updated 30/04/26) on easy access deposits — a rate that sits meaningfully above most high street banks and many of the digital challengers.

What you're actually getting

The 4.80% rate is a boosted variable rate, available for the first 12 months. After that initial period, the rate reverts — so if you open one now, you'll want a reminder in your calendar for early 2027 to review whether you should move your money elsewhere.

The account is flexible, which is relatively rare at this rate level. That means if you withdraw money during the tax year, you can re-deposit it without it counting against your £20,000 annual ISA allowance. For anyone who wants to keep their ISA topped up and might occasionally need to dip in, that flexibility has real value.

The minimum to open is £500. If you're transferring from an existing ISA, the minimum transfer is £10,000.

The triple access limit

This is probably the most important practical detail. The eToro Cash ISA is a triple access account — if you make more than three withdrawals in a 12-month period, your rate drops to 3.48% AER. That's still a reasonable rate, but it's a significant fall from 4.78%.

For most savers, three withdrawals a year is plenty. But if you're planning to use this account like a current account buffer — moving money in and out regularly — this product probably isn't the right fit.

Your money isn't held as a bank deposit

This is the most significant structural difference between eToro's Cash ISA and a traditional savings account, and it's one that often gets missed.

The money you put into eToro's Cash ISA is held in a Qualifying Money Market Fund (QMMF) — a type of very low-risk investment fund that tracks short-term interest rates. eToro uses this structure to deliver the interest rate rather than paying it as bank deposit interest.

In practice, the difference for most savers is minimal. QMMFs are considered extremely low risk, the returns are reliable, and you will receive the advertised rate. But it does have one material consequence: the FSCS protection you receive is different.

FSCS protection: £85,000, not £120,000

Standard cash savings accounts held with UK banks are currently protected up to £120,000 per person per institution under the Financial Services Compensation Scheme. Because eToro's Cash ISA uses a QMMF structure, it falls under investment-style FSCS protection — which caps at £85,000.

For the majority of savers, this difference is academic. If you're depositing £10,000 or £30,000, you're well inside either limit. But if you're a higher-balance saver — or you're planning to consolidate several years' worth of ISA transfers into a single account — the £85,000 cap is a real consideration. At that point, splitting across providers to stay within limits becomes the smarter play.

Every other easy access Cash ISA on our best-buy tables currently offers the higher £120,000 protection level.

Transfers in

eToro does accept transfers from existing Cash ISAs, which not all platforms currently support. The minimum transfer amount is £10,000. The transfer rate is the same as the new money rate — 4.78% — which is notably better than some competitors, where the transfer rate sits below the headline figure.

Transfers typically take 15 working days. You'll need to initiate the transfer through eToro's app; they handle the paperwork with your existing provider.

Watch out for the platform routing

eToro's primary business is investment and trading — contracts for difference, stocks, crypto. When creating an account, the platform will attempt to route you through its investment onboarding. Be deliberate: make sure you're selecting the Cash ISA specifically. If you're seeing references to portfolios, leverage, or trading features, you've ended up in the wrong part of the platform.

Customer support is app-based. There's no phone line, which is worth factoring in if you prefer to be able to speak to someone.

Who it's right for

The eToro Cash ISA makes strong sense if you're a new customer with at least £500 to deposit, you're comfortable with an app-only experience, you won't need to withdraw more than three times a year, and your total balance will stay below £85,000. At 4.78%, you'd be hard-pressed to find a better easy access rate right now.

It makes less sense if you need more than £120,000 of FSCS protection, you want unlimited access without any rate implications, or you'd prefer a traditional bank deposit structure with phone support.

The bottom line

4.78% is a standout rate and the eToro Cash ISA is a legitimate product. The QMMF structure and the lower FSCS limit aren't reasons to dismiss it — but they are reasons to understand what you're signing up for. For savers who fit the profile, it's the top easy access pick in the market right now.

Rate correct as of 3 April 2026. Variable rates can change. Always check the current rate before opening an account.
