Gross vs net on employment contract
On a Polish employment contract, job ads usually show monthly gross salary. The amount paid to your bank account is lower because social contributions, health contribution and income tax are deducted.
Example: a mid Backend in Warsaw, Krakow or Wroclaw has a source range of PLN 14,500–19,000 gross/month. A useful central benchmark is approximately PLN 16,750 gross/month, which is roughly PLN 10,215–13,282 net under simplified ZarobTo assumptions.
Brutto vs netto explained simplyB2B invoice vs estimated take-home
Backend B2B benchmarks are monthly net invoice amounts, excluding VAT. This is not personal take-home pay. From a B2B invoice you still need to cover taxes, ZUS, accounting, business costs, unpaid vacation, unpaid sick leave and downtime.
Example: a mid Backend B2B benchmark in the largest cities is PLN 18,000–23,500 net of VAT/month on an invoice. A useful central benchmark is approximately PLN 20,750 net of VAT/month. The real take-home amount depends on tax form, ZUS, costs and unpaid breaks.

PHP can still be competitive in senior product roles, but the market is narrower than Java, .NET or Node.js in many enterprise and scale-up environments.
