Calculate full contract-of-mandate cost for the client and net pay for the contractor. Social contributions and tax advance included.
The calculator estimates the cost of a contract of mandate for the principal (gross pay + employer ZUS) and net pay for the contractor (gross minus employee ZUS, PIT advance, health contribution). If exempt from ZUS (e.g. student under 26), ZUS = 0 — higher net, cost = gross.
| Contribution | Rate |
|---|---|
| ZUS — employee part (pension + disability + sickness) | 13.71% |
| ZUS — principal part (pension + disability + accident) | 17.93% |
| Min. contribution base (approx.) | 5,652 zł |
