Comparison of brokers for people starting to invest in Poland. XTB, mBank, Bossa, DEGIRO — fees, market access and ease of use.
9 min czytaniaWhy Does Broker Choice Matter?
Your broker is your gateway to financial markets. A bad choice means high fees, limited access to instruments and a frustrating interface. A good broker makes investing simple and cheap.
As a beginner, you don't need advanced tools. You need low costs, simple operation and access to ETFs.
What to Look For?
Fees and Charges
- Transaction fee — on GPW (Warsaw Stock Exchange) typically 0.19–0.39%
- Spread — difference between buy and sell price
- Account maintenance fee — some brokers charge for inactivity
- Currency conversion fee — crucial for foreign ETFs
Available Markets and Instruments
A beginning investor should have access to:
- GPW (Polish stocks)
- Foreign ETFs (Vanguard, iShares)
- Government bonds (though these are bought directly)
IKE and IKZE
Check if broker offers IKE/IKZE accounts — tax benefits accelerate capital building.

Which Broker to Choose — Decision in 3 Steps
Step 1: Define Strategy
- Only GPW + IKE/IKZE → mBank or Bossa
- Global ETFs without fees → XTB
- Wide access to foreign markets → DEGIRO or Interactive Brokers
Step 2: Check Costs for Your Scenario
Calculate real costs for planned transactions. If you invest PLN 500 monthly in one ETF, 0.39% fee is only PLN 1.95 — difference between brokers is minimal.
Step 3: Open Account and Start
Don't search for perfect broker for months. Choose a good one and start investing. Portfolio transfer is always possible.
Common Beginner Mistakes
- Choosing broker by advertisement — check real costs, not marketing slogans
- Ignoring currency conversion costs — with foreign ETFs, currency spread can eat savings on fees
- No IKE/IKZE — if investing long-term, tax benefits make huge difference
- Trading instead of investing — as beginner focus on regular ETF purchases, not speculation
