How do we calculate commissions?

The analyzer extracts your transactions from the CSV file and recalculates them using each broker's official fee schedule. We account for trade commissions, FX fees, minimums and maximums. The result is a realistic cost comparison.

Frequently Asked Questions

  • Where does the fee data come from?

    We source data from official broker pricing pages. Each fee schedule includes a last-verified date.

  • How accurate are the calculations?

    For brokers with transparent commissions (IBKR, DEGIRO, XTB) — 100% accurate. For spread-based brokers (eToro) — we provide estimates marked with ~.

  • Is my data safe?

    Yes. Your CSV file is processed securely on the server to prepare the analysis. Data handling depends on the selected mode and account settings described in the Privacy Policy, and we do not share your data with third parties for their own marketing purposes.

  • How often do you update the fees?

    We check broker pricing pages weekly. When a change is detected, we update our data within 24 hours.

  • Why aren't all brokers available?

    We currently support 6 of the most popular brokers in Poland. More are being added gradually.
