How to Buy US Stocks from Europe Without Paying Hidden Currency Fees

Buying US-listed shares as a European investor is now easier than ever—if you know how to avoid hidden costs. The largest of these? Currency conversion fees and spreads. In this tutorial, we’ll show you step-by-step how to buy US stocks from Europe with low fees, compare popular brokers (Trade Republic, DEGIRO, Interactive Brokers), and help you avoid nasty surprises. For a broader introduction to European investing, see our Ultimate Beginner’s Guide to European Stock Investing in 2026.

Step 1: Choose a Broker Optimized for Low FX Fees

What to do: Research and select a broker that offers transparent, low-cost currency conversions and direct access to US markets for EU residents.

• Trade Republic: Simple app, €1 flat trade fee, but all US stocks are bought in EUR only—no USD sub-account. FX conversion is automatic at their rate.
• DEGIRO: Low commissions, allows USD sub-account. Manual currency conversion possible, with explicit FX fee.
• Interactive Brokers (IBKR): Professional-grade, ultra-low FX fees (as low as 0.003% per trade), full multi-currency accounts, direct USD holdings.

Why it matters: Every time you buy a US stock in EUR, your broker converts your euros into dollars. Most brokers charge both a visible FX fee and an invisible “spread”—the difference between the wholesale and retail exchange rate. Over years, this can reduce returns by hundreds or thousands of euros.

What can go wrong: Many “zero commission” brokers bake in wide FX spreads, offsetting their low trade fees. If you don’t check the FX rate, you could pay 1–2% extra per trade. On €10,000 invested, that’s €100–€200 lost instantly.

Step 2: Fund Your Account in EUR—But Plan Your FX Conversion

What to do: Transfer euros from your SEPA bank account to your chosen broker. Decide whether you should let the broker handle FX automatically, or manually convert at a better rate.

• Trade Republic: Only accepts EUR. All US stock purchases are converted at their in-app rate (typically 0.5%–0.7% above interbank rate).
• DEGIRO: Accepts EUR. You can let DEGIRO auto-convert on each trade (0.25% fee), or use their “Manual FX” function (0.25% + €10 per conversion, but you can convert larger amounts at once to save).
• Interactive Brokers: Accepts EUR. You can hold both EUR and USD. Convert EUR to USD yourself inside the platform at the spot rate + $2 fee (on amounts up to $100,000).

Why it matters: Manual FX conversion lets you control timing and rates. If you plan to buy several US stocks, convert a larger amount once to minimize fees. Automatic conversion is simpler, but pricier per trade.

What can go wrong: If you use auto-conversion for every small trade, cumulative FX fees can eat into returns. Also, avoid sending USD directly from a European bank—most brokers reject or auto-convert at poor rates.

Step 3: Buy US Stocks—Compare Real EUR Costs

What to do: Place your order for a US-listed stock. Here’s how it works on each broker:

• Trade Republic:
  • Tap “Search” → Find your US stock (e.g. Apple, AAPL).
  • Tap “Buy” → Enter amount in EUR (e.g. €1,000).
  • Confirm order. The app shows estimated shares and their EUR cost, including FX.
• DEGIRO:
  • Go to “Products” → Search “AAPL” → Click “Buy”.
  • If you have USD in your account, select “Use USD balance” for zero FX fee.
  • If not, DEGIRO will auto-convert EUR at 0.25% fee. For large amounts, use “Manual FX” in “Account” → “Convert Currency”.
• Interactive Brokers:
  • Convert EUR to USD: Go to “Transfer & Pay” → “Convert Currency” → Enter amount (e.g. €1,000). Confirm at real-time rate + $2 fee.
  • Go to “Trade” → Search “AAPL” → Enter order in USD (e.g. $1,050, which is about €1,000 at 1.05 EUR/USD).
  • Place trade. You pay $0.35 commission per share (tiered, min $1). No FX fee if USD already in account.

Example calculation:

• Buy €1,000 of Apple (AAPL):
  • Trade Republic: €1,000 x (1 – 0.7% FX fee) = €993. €1 trade fee. Effective cost: €8 lost in FX, €1 fee.
  • DEGIRO: €1,000 x (1 – 0.25% FX fee) = €997.50 (if auto), plus €0.50–€1.00 trade commission.
  • Interactive Brokers: Convert €1,000 to $1,050 at spot rate + $2 fee (~€1.90). Trade AAPL: $1 commission (~€0.95). Total cost: €2.85.

Expected outcome: You should now see your first US stock purchase confirmed in your portfolio, with the EUR value and the number of shares visible. On IBKR and DEGIRO (with USD account), you’ll also see a USD cash balance.

Step 4: Understand Dividend Withholding Tax and Reporting

What to do: Check your broker’s handling of US dividend withholding tax (WHT) and ensure you submit the correct tax forms (W-8BEN) to benefit from reduced treaty rates.

• Trade Republic, DEGIRO, Interactive Brokers: All support W-8BEN form submission in-app. This reduces US dividend WHT from 30% to 15% for EU residents.
• Process: When you open your account, look for “Tax Information” or “W-8BEN” in your profile settings. Follow the prompts to submit electronically.

Why it matters: Without the W-8BEN form, you’ll pay 30% US withholding on dividends (e.g. €100 dividend = €70 received). With the form, only 15% is withheld. You can usually reclaim some or all of this tax in your local tax return, depending on your country’s rules.

What can go wrong: If you skip submitting the W-8BEN, you lose 15% of every dividend. Also, check if your broker passes on the full treaty rate—some (rarely) fail to do so.

Step 5: Monitor and Minimize Ongoing Costs

What to do: Review your broker’s ongoing fees: custody, inactivity, and FX on dividends. Reassess if your investment strategy changes or if your broker alters its fee structure.

• Trade Republic: No custody fee. All dividends paid in EUR (converted at their FX rate).
• DEGIRO: No custody fee (since 2021), dividends paid in EUR or USD depending on your account currency.
• Interactive Brokers: No inactivity or custody fee for most EU clients. Dividends paid in USD, no FX until you convert.

Why it matters: Over time, even small recurring fees (like automatic FX on each US dividend) can compound. For large portfolios, brokers with true multi-currency support (like IBKR) usually offer the lowest long-term cost.

What can go wrong: If your broker auto-converts every dividend to EUR, you’ll pay FX fees on each payment. For frequent dividend stocks, this adds up—especially at higher amounts.

Common Mistakes

• Ignoring FX spreads: Only looking at visible FX fees, not the true difference from the interbank rate.
• Choosing a “free” broker with hidden FX costs: Some platforms offer zero commissions but charge 1–2% on currency conversion.
• Not submitting W-8BEN: Missing out on reduced US dividend withholding tax.
• Frequent small trades: Triggering repeated FX conversions and higher cumulative fees.
• Neglecting tax reporting: Failing to declare US holdings or dividends, risking fines in your home country.

Next Steps

• Review your current broker’s FX and fee structure—request a cost breakdown if needed.
• Consider opening a multi-currency brokerage account (e.g. Interactive Brokers) if investing >€5,000 in US shares.
• Set up currency alerts for EUR/USD to optimize your next conversion.
