What this ZUS calculator covers

The calculator gives a quick monthly estimate based on your ZUS regime, tax form, costs, and contribution settings. It is designed for practical planning rather than abstract theory.

  • Social ZUS contributions
  • Health contribution
  • PIT advance estimate
  • Estimated net profit
  • Suggested percentage to set aside from each invoice

Who should use it

This page is useful for freelancers, consultants, and sole proprietors operating in Poland who want to understand how much ZUS they may owe in 2026 and how that affects monthly profit.

Why the calculator is only the starting point

A one-off estimate is useful, but real admin work continues after that. You still need deadlines, monthly tracking, invoice visibility, and a cleaner operating system for recurring finance tasks. That is where Rozlio fits in.
