Trading 212 vs Trade Republic vs Interactive Brokers: 2026 Comparison (UK & EU)

Disclosure. PieFolio AI is a portfolio tracker, not a broker. We receive zero commission from Trading 212, Trade Republic, or Interactive Brokers. Every fee, rate, and feature below reflects what each broker publicly advertises as of the Last updated date at the top — always reconfirm on the broker's own site before opening an account.

If you've spent any time researching brokers in 2026, you already know: the same three names come up in almost every "where should I open my account?" conversation. Trading 212, Trade Republic, and Interactive Brokers are the most-discussed self-directed brokers in the UK and Europe right now — and they're also wildly different products.

This is a side-by-side, table-heavy 2026 comparison built from a week of hands-on testing: opening live accounts at all three, executing real trades in EUR, GBP and USD, and pricing identical worked examples through each platform. Where the three brokers diverge most isn't headline commission — it's FX, execution venue, regulatory wrapper, and what happens when you actually want your money back in your home currency.

TL;DR — who wins for whom in 2026

At a glance

Numbers above are headline rates as of June 2026. The deep-dive sections explain the asterisks.

Fees in detail

The biggest myth in this comparison is that "all three are basically free." They're not — the invisible costs (FX, spreads, withdrawal, custody on some German tickers) are where the real difference lives.

Commissions and spreads

Honest read: for a UK investor buying VWRP every month in GBP, Trading 212 is genuinely free. For a German investor buying a €500 monthly ETF savings plan, Trade Republic is genuinely free. For someone moving $10k into US stocks and ever wanting it back in EUR, Interactive Brokers becomes the cheapest of the three within a single round trip because of the FX spread.

A worked example: €10,000 → 50 shares of AAPL → sell → back to EUR

This is why most experienced investors describe a clear tipping point: once you cross roughly €5,000 of US exposure, IBKR pays for its own learning curve.

Hidden cost: the spread you don't see

Trading 212 and Trade Republic both route to a market maker (Trading 212 to its own liquidity providers, Trade Republic to LS Exchange or gettex). That means the price you see already includes a small markup vs. the primary venue — typically 5–15 bps during European hours, but it can widen to 30+ bps outside Frankfurt hours or on illiquid US small-caps. IBKR routes directly to the primary exchange (SMART order routing in IBKR Pro), so what you see is what you pay. For an investor placing a single €10k trade at 22:00 local time, that invisible spread can quietly cost more than the commission they were avoiding.

Markets and instruments

If you only buy ETFs and large-cap stocks, all three cover you. The moment you want a Japanese ADR, a Norwegian small-cap, or a niche international ETF, only Interactive Brokers gets you there in one account.

Regulation, safety, and what actually happens if it goes bankrupt

This is the part most "best broker" articles hand-wave. Here's the unglamorous truth:

What this means in practice: Trade Republic's €20k EdW figure looks scary next to the others, but securities held in a German Wertpapierdepot are legally segregated client property — they don't become part of the broker's estate in insolvency. The €20k is the insurance ceiling on top of that segregation, not the cap on your portfolio's safety. Interactive Brokers' SIPC + excess insurance is the most generous on paper. Trading 212's FSCS £85k applies to UK clients only — Cypriot clients fall under the lower ICF €20k.

Interest on uninvested cash

Trading 212's rates only apply if you don't opt into stock lending, and they're tied to short-term central bank rates — they will drift. Trade Republic's 2.00% is bank-deposit (Solaris/Deutsche Bank), which makes it the most "set it and forget it." Interactive Brokers' rates are higher than they look once you cross the threshold, but balances under $10k earn nothing.

Platform and UX

If you've ever heard a friend say "I love my broker's app", they were almost certainly talking about Trading 212 or Trade Republic. If you've ever heard "my broker has a desktop platform that looks like Bloomberg from 2003", that's IBKR — and the people who use it daily love it for exactly that reason.

Worth flagging. Trading 212 shipped a free public REST + WebSocket API in 2024 covering account data, instruments, history, and order placement. It is rate-limited and requires opt-in from account settings, but it works — and a lot of older comparisons still incorrectly say it doesn't exist.

Who each broker is genuinely best for

After testing all three with the same capital, three clear profiles emerge:

Trading 212 fits best if you're a UK or EU investor who values simplicity over breadth, wants a free ISA wrapper (UK only), and plans to buy mostly large-cap stocks and mainstream ETFs in your home currency. The AutoInvest "pies" feature genuinely lowers the friction of monthly DCA to near-zero. The friction shows up only if you want options or to trade at unusual hours.

Trade Republic fits best if you're a eurozone investor whose investing life is "€500 into a global ETF every month, forever." Free savings plans, a clean mobile app, and the option to park idle EUR at 2.00% make it the lowest-friction option in continental Europe. It's a poor fit if you need a desktop platform, trade large US positions, or live outside its supported tax-reporting countries.

Interactive Brokers fits best if you take investing seriously enough to spend an afternoon learning the platform. The cheapest FX in the industry, real options, 150+ exchanges, and the strongest insurance stack on this list compound into massive savings once your portfolio grows past about €20k or once you start trading internationally. The cost is a UI that feels engineered for institutions — because it is.

Most experienced investors we spoke to (and most veteran Redditors) end up with two brokers: one neobroker for the convenience and one IBKR for the heavy lifting. There's no rule that says you have to pick one.

FAQ

Is Trading 212 safe? Yes for the amounts most retail investors hold. UK clients are FSCS-protected up to £85,000. Cypriot clients fall under the lower ICF €20,000. Securities are held in segregated nominee accounts.

Does Trade Republic have a desktop platform? No. It is mobile-first by design and there is no full-featured web app. You can view positions in a browser but cannot place trades from the desktop.

Is Interactive Brokers cheaper than Trading 212? For pure GBP or EUR trading in your home market, no — Trading 212 is free. For US trading or anything involving FX, IBKR is meaningfully cheaper once your trade size exceeds about €1,000.

Can I have all three? Yes. Many investors do — Trading 212 for the ISA, Trade Republic for EUR ETF savings plans, IBKR for everything international.

Which broker has the best interest on cash? Headline-rate wise, Trading 212. But Trade Republic's 2.00% is bank-deposit (more boring, more stable), and IBKR's tiered rates can beat both above the $10k threshold.

Which one is best for dividend investors? All three pay dividends correctly, but Interactive Brokers handles foreign withholding tax most cleanly. Trading 212's dividend tracking inside the app is the friendliest.

Do any of them offer a JISA, SIPP, or LISA? No. As of June 2026, none of the three offers a SIPP, LISA, or JISA. Trading 212 is the only one with an ISA.

What about Revolut or Lightyear? Different category — they're FX-first products that have added brokerage rather than self-directed brokers built around it. We cover Lightyear in the Best Stock Brokers in Europe & the UK pillar.

Does PieFolio AI receive money from any of these brokers? No. There is no affiliate, referral, or paid placement relationship with any broker mentioned.

When was this last verified? Fee schedules and interest rates were checked the week of the Last updated date at the top of this page. Brokers change pricing frequently — always reconfirm on their own site before opening an account.
