How to Track Your Multi-Broker Portfolio as a European (2026 Tutorial)

Managing investments across several brokers is increasingly common for Europeans seeking low fees, product diversity, and access to global markets. But tracking your multi-broker portfolio can get messy—especially if you hold EUR, USD, and crypto assets. This tutorial will walk you through the exact steps to consolidate your holdings, monitor performance, and avoid common pitfalls using tools and workflows available in 2026.

Step 1: List All Your Brokers and Asset Types

What to do: Create a simple inventory of every broker and platform where you hold investments. Include traditional brokers (e.g., Trade Republic, DEGIRO), international brokers (e.g., Interactive Brokers), and crypto platforms (e.g., Bitpanda, Kraken). For each, note:

• Platform name
• Account currency (EUR, USD, GBP, etc.)
• Asset types held (e.g., stocks, ETFs, crypto, cash)

Why it matters: This inventory is your foundation. Without a full list, you’ll miss assets or duplicate them, leading to inaccurate tracking and reporting—especially crucial for tax purposes in Europe.

What can go wrong: Forgetting small or legacy accounts (old brokerages, dormant crypto wallets) is common. Missing these can skew your net worth calculation and tax reporting.

Step 2: Export or Collect Your Holdings Data

What to do: For each broker, download your current holdings as a CSV or Excel file. Here’s how on major European platforms:

• Trade Republic: Tap Portfolio → Export → Download CSV
• DEGIRO: Go to Portfolio → Export → Excel
• Interactive Brokers: Click Portfolio → Reports → Portfolio Analysis → Export
• Bitpanda: Navigate to Wallet → Export Portfolio

For brokers that don’t offer easy exports, manually note down:

• Asset name (e.g., “iShares Core MSCI World UCITS ETF”)
• Ticker (e.g., IWDA)
• Number of units
• Currency
• Market value

Why it matters: Accurate, up-to-date data is essential for aggregation. If you skip this step or use outdated data, your portfolio overview will be misleading.

What can go wrong: Some brokers only show positions in account currency, hiding underlying asset currency. For example, DEGIRO may show your US ETF position in EUR, even if the ETF is USD-denominated.

Step 3: Choose Your Tracking Method (App vs. Spreadsheet)

What to do: Decide between an automated portfolio tracking app and a custom spreadsheet. Here are the best options for Europeans in 2026:

• justETF (Europe-wide): Free and paid plans, supports manual and automated syncing, handles EUR/USD/GBP, and most European brokers.
• Portfolio Performance (desktop): Open source, advanced analytics, supports multi-currency and custom asset classes.
• Finary (France and EU): Connects to most European banks/brokers, supports crypto, real estate, and alternative assets.
• Spreadsheet templates: Google Sheets or Excel, fully customizable. Try the “Multi-Broker Portfolio Tracker” template from justETF or build your own (see workflow below).

Why it matters: Apps save time and reduce manual data entry but may have limited coverage for certain brokers or asset types. Spreadsheets offer total control and transparency but require more ongoing effort.

What can go wrong: Some apps only support popular brokers (Trade Republic, DEGIRO, Interactive Brokers). If you use a niche platform or have complex crypto holdings, you may need to supplement with manual entries or a spreadsheet.

Step 4: Import and Consolidate Your Holdings

What to do:

• In a portfolio app: Use the “Add Account” or “Connect Broker” feature. For example, in Finary, tap Add Account → Broker → Select your broker → Connect (using secure APIs or read-only access).
• In justETF: Go to Portfolio → Import Holdings → Upload CSV or enter manually.
• In a spreadsheet: Create columns for Broker, Asset, Ticker, Units, Currency, Value (EUR), Original Currency, and Exchange Rate. Paste your exported data in, and use =GOOGLEFINANCE() or similar functions to fetch live prices and FX rates.

Why it matters: Consolidation lets you see your full asset allocation, risk exposure, and performance across all platforms. This is vital for rebalancing, tax reporting, and understanding your true net worth.

What can go wrong: Double-counting assets (e.g., if you forget to update a sold position), mixing up currency conversions, or accidentally omitting an account can all distort your overview.

Step 5: Manage Multiple Currencies (EUR, USD, Crypto)

What to do: Standardize all values to EUR for a unified view. For each holding:

• Identify the asset currency (e.g., USD for S&P 500 ETFs, EUR for European stocks, BTC or ETH for crypto)
• Fetch the current exchange rate (e.g., =GOOGLEFINANCE("CURRENCY:USDEUR") in Google Sheets)
• Convert each position’s market value to EUR
• For crypto, use a reputable source like CoinGecko or your app’s built-in rates

Why it matters: Without converting to a single currency, your asset allocation and performance metrics are distorted. This is especially critical for rebalancing and for calculating your tax base in your country of residence.

What can go wrong: Using outdated or inconsistent FX rates can cause significant errors, especially for large USD or crypto positions. Some apps update rates daily; others require manual refresh.

Step 6: Visualize and Analyze Your Portfolio

What to do: Use your app or spreadsheet’s built-in visualization tools (pie charts, allocation graphs, performance over time) to:

• See your asset allocation by asset class, region, and currency
• Track performance (total return, annualized return, volatility)
• Spot concentration risk (e.g., too much in US tech stocks or a single crypto)

Why it matters: Visual feedback helps you spot imbalances, react to market changes, and make informed rebalancing decisions. It also makes reporting (e.g., for tax or financial planning) much easier.

What can go wrong: If your data isn’t updated regularly, your analytics become unreliable. Also, be careful with chart settings—some tools default to showing only certain accounts or currencies.

Step 7: Secure Your Data and Privacy

What to do:

• Enable two-factor authentication (2FA) on all broker and tracker accounts
• For apps: Check their privacy policy and data storage (EU servers preferred, GDPR-compliant)
• For spreadsheets: Store in a secure cloud (Google Drive, OneDrive) with strong passwords and sharing restrictions
• Regularly back up your data (especially if you use local software like Portfolio Performance)

Why it matters: Portfolio data is sensitive. Breaches can lead to financial loss or identity theft—especially if you store account numbers or balances.

What can go wrong: Using weak passwords, reusing credentials, or sharing files carelessly can expose your entire financial picture to hackers or third parties.

Common Mistakes When Tracking a Multi-Broker Portfolio

• Forgetting to update your data after trades, deposits, or withdrawals—leading to misleading overviews
• Ignoring currency effects, especially if you hold significant USD or crypto assets
• Double-counting assets when transferring between brokers (e.g., moving ETFs from DEGIRO to Interactive Brokers)
• Neglecting tax implications of crypto or foreign holdings—see our Crypto Tax 2026 guide for more
• Relying solely on apps that don’t support all your brokers, leaving gaps in your tracking

Next Steps

• Review your tracking setup monthly and after major trades or deposits
• Explore automation—see our guide to automating savings and investing for European fintech tools
• Consider advanced analytics or robo-advisors as your portfolio grows—see our comparison of European robo-advisors
• Stay informed about new tools and regulations—2026 brings ongoing changes in European investment platforms and reporting standards

By following these steps, you’ll gain a clear, actionable view of your entire investment picture—no matter how many brokers or currencies you use. This empowers you to make smarter decisions, rebalance effectively, and avoid costly mistakes as a European investor.
