Side-by-Side Comparison

Which Broker to Choose? Recommendations

Beginner investor (up to 10,000 PLN)

→ XTB. Zero commissions, fractional shares, and an intuitive app. With small amounts, the minimum commission at competitors (5 PLN) eats too much of your investment.

mBank customer seeking convenience

→ mBank eMakler. Banking integration, instant transfers, everything in one app. Zero commissions on selected ETFs are sufficient for building a DCA portfolio.

Experienced GPW investor

→ Bossa. Broadest Polish market access, futures, Catalyst. Advanced analytical tools that competitors lack.

Long-term investor (IKE/IKZE)

→ XTB — zero commissions on ETFs within IKE/IKZE make it the ideal choice for DCA strategies. Alternatively, Bossa if you want to invest in Polish bonds.

FAQ

Can I have accounts at multiple brokers simultaneously?

Yes. There are no restrictions — you can have accounts at XTB, mBank, and Bossa simultaneously. The only limitation applies to IKE and IKZE: you can have only one IKE and one IKZE (but at different brokers). Transferring IKE/IKZE between brokers is possible.

Which broker is the safest?

All three platforms are regulated by KNF (Polish Financial Supervision Authority). Client funds are segregated from broker funds and covered by the KDPW compensation system (up to 20,100 EUR equivalent). XTB, as a publicly listed company, is subject to additional transparency requirements.

Does XTB really charge zero commission?

Yes, up to 100,000 EUR monthly turnover, the commission is 0 PLN on stocks and ETFs. Above this limit, a 0.2% commission applies (min. 10 EUR). For most individual investors, the limit is more than sufficient — 100,000 EUR equals over 430,000 PLN in monthly turnover.
