Choosing the right brokerage platform is one of the most critical decisions for any retail investor. In Europe, two platforms dominate the conversation for self-directed portfolios: DEGIRO and Interactive Brokers. While both offer highly competitive fee structures compared to traditional retail banks, they cater to fundamentally different types of investors. This comprehensive degiro vs interactive brokers analysis breaks down their regulatory frameworks, fee structures, platform features, and market access to help you determine which platform aligns with your financial strategy.
When evaluating a broker, it is easy to get lost in complex fee schedules and technical jargon. DEGIRO has built its reputation on simplicity and a user-friendly interface designed for European retail investors. Interactive Brokers (IBKR), on the other hand, is a global powerhouse known for institutional-grade trading tools, advanced order routing, and unparalleled market access. In this review, we look past the marketing claims and analyze the specific, verifiable data points that define these two brokerage giants.
Regulatory Framework and Investor Protection
Before depositing capital, understanding the security of your assets is paramount. Both DEGIRO and Interactive Brokers are highly regulated, but their corporate structures and investor compensation schemes differ significantly due to their geographic origins and operational setups.
DEGIRO Regulatory Setup
DEGIRO merged with the German flatex AG in 2020, forming flatexDEGIRO Bank AG. This merger transformed DEGIRO from a pure investment firm into a regulated German bank. Consequently, DEGIRO operates under the direct supervision of the German Federal Financial Supervisory Authority (BaFin).
- Cash Deposits: Because DEGIRO accounts are hosted by flatexDEGIRO Bank, your uninvested cash is held in a personal bank account with a German IBAN. These cash deposits are protected up to €100,000 under the German Deposit Guarantee Scheme (Entschädigungseinrichtung deutscher Banken).
- Investment Protection: Your financial instruments (stocks, ETFs, mutual funds) are held in a separate legal entity (SPV) to segregate them from DEGIRO’s corporate assets. If DEGIRO were to face insolvency, your investments remain safe. In the rare event of asset administration irregularities, the German Investor Compensation Scheme covers up to 90% of lost investment assets, capped at €20,000.
Interactive Brokers Regulatory Setup
Interactive Brokers Group is a massive, publicly traded US corporation (NASDAQ: IBKR) with multiple regional subsidiaries. For European clients, IBKR historically routed accounts through its UK entity. However, post-Brexit, European clients are assigned to specific EU subsidiaries, primarily Interactive Brokers Ireland Limited (regulated by the Central Bank of Ireland) or Interactive Brokers Central Europe (based in Hungary and regulated by the Magyar Nemzeti Bank).
- Investor Protection Schemes: The protection limits depend on which regional subsidiary hosts your account:
- IBKR Ireland: Covered by the Irish Investor Compensation Scheme, which protects 90% of lost assets up to a maximum of €20,000.
- IBKR Central Europe (Hungary): Protected by the Hungarian Investor Protection Fund, which offers coverage up to €100,000 (with a sliding scale of coverage for amounts above €20,000).
- IBKR US (for eligible international clients): Protected by the Securities Investor Protection Corporation (SIPC), which covers up to $500,000 (including a $250,000 limit for cash).
Both brokers enforce asset segregation, meaning client assets are kept separate from the broker’s operational funds. From a regulatory perspective, both are highly secure, but IBKR’s status as a publicly traded company with a massive capital reserve adds an extra layer of corporate transparency.
Market Access and Supported Asset Classes
The range of available financial instruments determines how effectively you can diversify your portfolio. In this category, the contrast between the two brokers is stark.
DEGIRO Market Coverage
DEGIRO offers access to approximately 30 exchanges across Europe, North America, and parts of the Asia-Pacific region.
- Supported Assets: Stocks, ETFs, Options, Futures, and structured products.
- Limitations: DEGIRO does not support direct forex trading (you can only convert currency to buy assets), nor does it support contract for difference (CFD) trading, cryptocurrencies (except via ETPs/ETFs), or physical precious metals. Fractional shares are not supported, which can make dollar-cost averaging into high-priced stocks difficult for smaller portfolios.
Interactive Brokers Market Coverage
Interactive Brokers is widely considered the industry leader in market access. It provides entry to over 150 markets across 33 countries, supporting 26 different currencies.
- Supported Assets: Stocks, ETFs, Options, Futures, Forex (spot FX trading at institutional rates), Bonds (government and corporate), Mutual Funds, CFDs, and direct Cryptocurrency trading (via Paxos Trust Company).
- Fractional Shares: IBKR fully supports fractional shares for US and eligible European stocks, allowing you to invest exact cash amounts regardless of the share price.
For investors seeking global diversification, emerging markets access, or complex derivative instruments, Interactive Brokers is the clear winner.
Trading Platforms and User Experience
The interface you use daily can significantly impact your execution speed and overall satisfaction. Here, the choice depends on your technical expertise.
DEGIRO: Simplicity and Intuitive Design
DEGIRO’s platform is designed with the retail investor in mind. Available via a web browser and a mobile app, the interface is clean, uncluttered, and easy to navigate.
- Usability: Placing an order takes only a few clicks. The search functionality is straightforward, allowing you to find assets by name, ticker, or ISIN.
- Tools: Charting tools are basic. While you can apply standard technical indicators (like moving averages or RSI), the platform lacks deep analytical capabilities. There are no paper trading accounts (demo accounts) available to practice strategies risk-free.
Interactive Brokers: Professional Power and Complexity
Interactive Brokers offers a suite of platforms tailored to different experience levels:
- Client Portal: A web-based platform suitable for basic portfolio management and simple trades.
- IBKR Mobile: A highly capable mobile app that includes advanced charting and order types.
- Trader Workstation (TWS): IBKR’s flagship desktop platform. TWS is an institutional-grade software package that offers advanced charting, algorithmic trading options, real-time risk scanners, and deep API integrations.
- IBKR GlobalTrader: A simplified mobile app launched specifically to compete with modern neo-brokers, offering a clean interface for basic stock and ETF trading.
While TWS has a notoriously steep learning curve that can overwhelm beginners, it provides unmatched analytical power. IBKR also offers a fully functional paper trading account, allowing you to test the platform with virtual money before committing capital.
Fee Structure and Currency Conversion
Fees are the most critical factor affecting long-term portfolio returns. When comparing the transaction costs of degiro vs interactive brokers, you must look beyond the headline commission rates and analyze currency conversion fees, connectivity fees, and financing rates.
Transaction Fees
- DEGIRO: Operates on a flat-fee or low-variable commission structure. For example, trading US stocks costs a flat fee of €1.00 per trade (plus a €1.00 handling fee). Trading on local European exchanges typically costs between €2.00 and €5.00 plus a handling fee.
- Interactive Brokers: Offers two fee models: Fixed and Tiered.
- Fixed Pricing: A flat rate per share or a flat percentage of the trade value (e.g., $0.005 per share for US stocks, minimum $1.00).
- Tiered Pricing: Commissions decrease as your trading volume increases. For low-volume retail traders, Tiered pricing is often cheaper, with US stock trades costing as little as $0.35 per trade.
Currency Conversion Fees
For European investors purchasing US assets, currency conversion is often the largest hidden cost.
- DEGIRO: Charges a steep 0.25% fee on currency conversions via its automatic AutoFX system. If you buy €10,000 worth of US stocks, you will pay €25 just for the currency swap.
- Interactive Brokers: Charges an exceptionally low spot FX rate of 0.002% of the trade value, with a minimum fee of $2.00 per transaction. Converting €10,000 to USD on IBKR costs only the minimum fee of $2.00 (€1.85), making it dramatically cheaper than DEGIRO for international traders.
Connectivity and Maintenance Fees
- DEGIRO Connectivity Fee: DEGIRO charges a €2.50 annual connectivity fee per exchange for every exchange you trade on during the calendar year (excluding your home exchange). If you hold stocks on the NYSE, NASDAQ, and Xetra, you will pay €5.00 annually in connectivity fees.
- IBKR Inactivity Fees: Interactive Brokers officially eliminated its $10 monthly inactivity fee in July 2021. There are no account maintenance fees, making it completely free to maintain an idle account.
| Fee Category | DEGIRO | Interactive Brokers (Tiered) |
|---|---|---|
| US Stock Commission | €1.00 commission + €1.00 handling fee | $0.0035 per share (Min. $0.35, Max. 1.0% of trade value) |
| European Stock Commission | €2.00 to €4.90 depending on exchange | 0.05% of trade value (Min. €1.25 to €3.00 depending on country) |
| Currency Conversion (FX) | 0.25% of transaction value | 0.002% of transaction value (Min. $2.00) |
| Connectivity / Inactivity Fee | €2.50 per year per non-home exchange | None ($0.00) |
Margin Accounts and Interest Rates
For advanced investors who utilize leverage (borrowing against their portfolio), margin rates are a crucial differentiator.
Interactive Brokers is globally renowned for offering some of the lowest margin rates in the financial industry. For IBKR Pro accounts, margin rates are calculated dynamically based on benchmark interest rates plus a small markup (typically ranging from 1.5% to 2.5% depending on the borrowed amount).
DEGIRO’s margin lending (referred to as “Debit Money”) is significantly more restrictive and expensive. DEGIRO requires you to pre-allocate your margin requirements to receive a lower rate (which is still generally higher than IBKR’s base rate). Unallocated margin usage on DEGIRO incurs steep interest charges, often exceeding 5.25% to 6.00% per annum.
If margin trading or short selling is a core part of your strategy, Interactive Brokers is the industry-standard choice.
Conclusion: Which Broker Fits Your Use Case?
Both platforms are highly secure, reputable, and capable of hosting your long-term investments, but they serve different profiles.
Choose DEGIRO if:
- You are a beginner or intermediate investor based in Europe who prefers a clean, simple, and jargon-free interface.
- You primarily buy European-listed ETFs or local stocks in your home currency (Euro), which avoids DEGIRO’s 0.25% currency conversion fee.

Choose Interactive Brokers if:
- You are an active trader or advanced investor who requires institutional-grade platforms like Trader Workstation (TWS).
- You regularly trade US-listed stocks, options, or foreign assets, as IBKR’s currency conversion fees are vastly superior to DEGIRO’s AutoFX rates.
- You want to utilize low-cost margin leverage or require access to global emerging markets.
- You want to automate your strategies using APIs or trade fractional shares.
