Best App for Fractional Shares 2026 — Europe

TL;DR

Data shows three apps consistently win for European investors who want true fractional share investing in 2026. Trading 212 is the top pick for casual investors thanks to zero commissions, 0.15% FX, and 13,000+ instruments available from £1 or €1. Lightyear ranks second for clean equity-only investing with $0.20 per US share and €1 per EU ETF, regulated by the Estonian FSA. Interactive Brokers wins for power users moving more than €20,000 with $0.0035 per share and access to 23,000+ stocks across global markets. The winning use case is monthly small-ticket investing in expensive US names like NVDA, MSFT, or BRK.B without forking out hundreds per share. Key tip: always check the FX spread, not just the headline commission — a "free" trade with 0.50% FX is more expensive than a $1 trade with 0.15% FX on any USD purchase above $200.

Why Fractional Shares Matter More Than Ever in 2026

Fractional shares used to be a curiosity — a Robinhood gimmick reserved for the US market. By 2026, they are a serious tool for European investors building diversified portfolios on modest budgets. Many investors consider them essential for three reasons.

First, single-share prices have ballooned. Berkshire Hathaway Class A trades north of $700,000. Even Class B is over $400. Costco, Eli Lilly, ASML, NVIDIA — all command share prices that would force a small investor to allocate disproportionate capital to a single name. Fractional shares let you put exactly €50 into NVDA every month regardless of what the share price does.

Second, dollar-cost averaging only works smoothly when you can buy any amount. If your monthly contribution is €200 and your target ETF is €95 per share, you either buy two shares and leave €10 uninvested or break the budget. Fractional buying invests every cent.

Third, diversification at small portfolio sizes becomes mathematically possible. With €1,000 you can buy meaningful slices of ten different stocks via fractional shares. The same €1,000 in whole shares of US blue chips might cover only two or three positions.

The catch: not every European broker offers true fractional shares, and the ones that do differ wildly in cost structure, instrument coverage, and execution quality. This is what we measured.

Top 5 Apps for Fractional Shares in Europe

1. Trading 212 — Best Overall for Casual Investors

Trading 212 has become the default fractional share platform for retail investors across Europe. It combines zero commissions, the lowest FX fee in its class (0.15%), and the broadest instrument list (over 13,000 stocks and ETFs). The Pies feature lets you build custom baskets and AutoInvest contributions in fractional amounts down to £1 or €1.

Regulation is split between the FCA in the UK and CySEC in Cyprus for EU clients, with deposit protection up to £85,000 (UK) or €20,000 (CySEC investor compensation). Onboarding takes under 10 minutes for most EU residents. The app is mobile-first but offers a usable web platform.

Limitations: Trading 212 holds shares in nominee structure (common in EU brokers) and does not pass on US tax forms automatically — you self-declare W-8BEN at signup. Cash interest on uninvested EUR is competitive but variable.

2. Lightyear — Best for Equity Purists

Lightyear strips away CFDs, crypto, and copy-trading distractions, focusing purely on stocks and ETFs. Fractional buying is supported on most US and EU equities. Pricing is transparent: $0.20 per US share, €1 per EU ETF trade, and 0.35% FX (slightly higher than Trading 212).

Regulated by the Estonian FSA with full MiFID II passporting, Lightyear offers around 5,000 instruments. The mobile app rates well on both stores and the platform pays interest on uninvested cash in multiple currencies. For investors who want a clean, focused interface and fee structure they can predict line by line, Lightyear is the cleanest choice.

3. Interactive Brokers — Best for Power Users

IBKR is overkill for €100/month investors but unbeatable once your portfolio crosses €20,000. Fractional shares are available on most US-listed stocks and many European ones. Commission is $0.0035 per share with a $0.35 minimum on US trades — meaning a €100 fractional purchase can cost just $0.35.

The IBKR Pro account adds tiered pricing that drops costs even further at scale. FX is exceptional at roughly 0.20% (versus 0.50% at Revolut Standard or 0.25% at Revolut Premium). Instruments available exceed 23,000 across 150+ markets. The downside is the learning curve — TWS and the mobile app are professional tools, not beginner playgrounds.

4. Scalable Capital — Best for German-Speaking Markets

Scalable Capital offers fractional shares within its PRIME+ subscription (€4.99/month), which also unlocks unlimited free trades on Gettex and ETF savings plans on 1,700+ ETFs. Regulation by BaFin gives German investors confidence and full deposit insurance up to €100,000.

Fractional buying is currently limited to a subset of stocks and ETFs (around 1,500 instruments at the time of writing) and is most useful inside savings plans rather than ad-hoc trades. For DACH-region investors who want a single platform combining ETF DCA and fractional single-stock investing, Scalable is well-positioned.

5. Revolut — Best for First-Timers Already in the Ecosystem

Revolut is not the cheapest fractional share platform, but it is the most accessible. Around 30 million European users already have the app for currency exchange. Standard accounts allow $1 per trade with 0.25% FX, and roughly 2,000+ US stocks and a limited ETF selection are available fractionally.

The trade-off is steep. Revolut's stock execution is via Revolut Securities (Lithuania) and FX above the monthly free allowance jumps to 1.0% for Standard. For investors moving more than €1,000/month, the costs compound quickly. But for someone making their first ever stock purchase from inside an app they already trust, the friction reduction is unmatched.

Comparison Table

Real-World Cost Example

Let's run two scenarios for a European investor in 2026.

Scenario A: €500 lump sum into NVDA (fractional, USD-denominated)

Assuming an FX rate of 1.08 USD/EUR and a notional NVDA share price of $140:

• Trading 212: €500 → $540 at mid-rate. FX cost 0.15% = €0.75. Commission €0. Total cost: €0.75, you receive ~3.857 shares.
• Lightyear: FX cost 0.35% = €1.75. Commission $0.20 (rounded to one share-equivalent unit). Total cost: ~€1.93.
• IBKR: FX cost 0.20% = €1.00. Commission minimum $0.35 = €0.32. Total cost: €1.32.
• Scalable Capital PRIME+: monthly fee amortized, spread-based FX roughly 0.30% = €1.50. Commission €0 for PRIME+. Total cost (excluding subscription): €1.50.
• Revolut Standard: FX cost 0.25% = €1.25. Commission $1 = €0.93. Total cost: €2.18.

Scenario B: €100/month DCA into VWCE (EUR-denominated ETF) for 12 months

VWCE is EUR-denominated so no FX is required.

• Trading 212: €0 commission per Pie/AutoInvest contribution. Annual cost: €0.
• Lightyear: €1 per ETF trade × 12 = €12 annually.
• IBKR: €1.25 per trade × 12 = €15 annually.
• Scalable Capital PRIME+: €0 commission, but €4.99 × 12 = €59.88 subscription. Worthwhile if you make many other trades; expensive for one €100 ETF/month.
• Revolut: ETFs limited; if available, £1 per trade × 12 = ~€14.

For pure ETF DCA in EUR, Trading 212 wins handily. For mixed US stock + ETF investing, Trading 212 still wins below ~€20,000 portfolio size, then IBKR takes over.

Best for European Investors Specifically

Country availability matters because not every fractional broker passports into every EU/EEA country. As of early 2026:

• Poland: Trading 212, IBKR, Lightyear, Revolut, XTB (no fractional ETFs but fractional US stocks). Scalable Capital limited.
• Germany: All five major platforms available; Scalable Capital and Trade Republic dominate locally.
• France: Trading 212, IBKR, Revolut, Lightyear, Scalable Capital. Fractional shares not eligible for PEA tax wrapper — use whole shares in PEA, fractional outside.
• Netherlands / Belgium: Trading 212, IBKR, Lightyear, Revolut. Belgian TOB (transaction tax) applies regardless of fractional status.
• Italy / Spain: Trading 212, IBKR, Revolut, Lightyear; Scalable Capital available in Italy via Fineco partnerships.
• Nordics: IBKR universally; Trading 212 and Lightyear in most; Revolut everywhere.

Tax wrappers are the biggest catch. The French PEA, UK ISA (post-Brexit, not relevant for EU residents), and Italian PIR all impose restrictions on fractional shares or non-domiciled instruments. Always verify before assuming you can hold a fractional US stock inside a tax-advantaged account.

Common Pitfalls

FX bleed on every transaction. The single biggest hidden cost. Buying a $200 fractional NVDA share through Revolut Standard costs €0.50 in FX alone. Over 12 monthly purchases that is €6 — more than the platform's apparent zero commission saved you.

Dividend handling on fractional positions. Some brokers reinvest fractional dividends as cash, others as fractional units. Trading 212 reinvests automatically; Revolut credits cash. The difference compounds over decades.

Voting rights and corporate actions. Most brokers do not pass through voting rights on fractional positions. If voting matters to you (rare for retail), verify the broker's policy.

Sale execution. Fractional shares typically cannot be transferred to another broker. You must sell before transferring, triggering a taxable event in most jurisdictions. Treat fractional positions as somewhat illiquid for portability.

Hidden inactivity fees. IBKR previously charged inactivity fees but removed them in 2021. Some smaller platforms still charge €10/month if you make no trades for a quarter. Read the fee schedule.

Slippage on small fractional buys. Brokers aggregate fractional orders and execute at end-of-bar prices. For volatile stocks during opening minutes, the price you see and the price you get can differ noticeably.

How We Ranked

Our methodology weighed five factors:

1. Total cost of ownership (35%) — Commission + FX + spreads + subscription, modeled across €100/month and €1,000 lump-sum scenarios.
2. Instrument breadth (20%) — Number of fractional-eligible stocks and ETFs, with bonus weight for non-US instruments.
3. Regulatory strength (15%) — Tier-1 EU regulator status, deposit protection size, segregated accounts.
4. User experience (15%) — App store ratings, onboarding time, language coverage, support responsiveness in tests.
5. Country availability (15%) — How many EU/EEA countries can actually open an account.

We then ran identical purchase scenarios on each platform and verified actual fees against published schedules. Fees and features change frequently — verify on the broker's site before opening an account.

Alternatives if These Don't Work

If none of the top five fits — perhaps you live in an underserved country, prefer a local-language platform, or need a specific instrument none of them offer — consider these niche alternatives:

• eToro for fractional shares with social copy-trading. Higher implicit costs (spreads), but unique social features.
• Bunq Investing for Dutch and German investors who want banking and fractional ETF investing in one app, with strong UX but limited instrument range.
• XTB for Polish, Czech, and Hungarian investors who prefer a local regulator (KNF) and zero commissions on stocks below €100k/month volume.
• DEGIRO for whole-share investors who can live without fractional buying but want the cheapest custody. DEGIRO added Auto-Invest fractional support in 2024 but it remains limited.
• Fineco for Italian residents who want a full-service Italian bank with fractional capabilities inside savings plans.

FAQ

Are fractional shares the same as the underlying stock? Economically yes — you receive proportional dividends and benefit from price appreciation. Legally, you typically own a beneficial interest held by the broker rather than direct registered shares. Voting rights and corporate-action handling vary.

Can I transfer fractional shares to another broker? Almost never. Most brokers require you to sell fractional positions before transferring the rest of your portfolio. This can trigger capital-gains tax events.

Are fractional shares taxed differently? No. They are taxed identically to whole shares — capital gains apply on disposal, dividends on receipt. Polish 19% Belka tax, German 26.375% Abgeltungsteuer + Soli, and so on apply normally.

Can I buy fractional shares of any stock? Each broker maintains a list. Trading 212 covers most US and many EU stocks fractionally. Lightyear covers a curated 5,000+. IBKR covers most US-listed and a growing EU list. Always check the broker's instrument page before assuming fractional eligibility.

Is there a minimum purchase amount? Yes, usually €1 or $1. Some brokers (IBKR) require slightly more for non-US instruments. The minimum applies to the order size, not the share fraction itself.

Track Your Fractional Holdings Across Multiple Apps

If you spread fractional positions across two or three brokers — common when one offers better FX and another better instrument coverage — you'll need a way to see your true cost basis and total exposure. Freenance lets you track positions across multiple brokerage apps and consolidates cost basis, dividends, and FX impact in one dashboard, which is essential when fractional shares from different platforms make manual spreadsheets unreliable.
