    print(f"{city['city']}: €{city['avg_gross']:,} gross / €{city['avg_net_est']:,} net (est.)")

Response Format

Each response includes top-level metadata alongside the data:

{
  "source": "ExpatNetherlandsHub.com",
  "source_url": "https://expatnetherlandshub.com/salary-comparison/",
  "last_updated": "2026-03-17",
  "license": "Free to use with attribution link to source_url",
  "data": { ... }
}

The source_url field points directly to the page where the data originates — this is the URL you should use for your attribution link.

Attribution Requirement

The data is free to use. The one requirement is that you include a visible link to ExpatNetherlandsHub.com as your data source — either to the homepage or to the specific source_url returned in the response.

Example attribution:

Data source: <a href="https://expatnetherlandshub.com/salary-comparison/">ExpatNetherlandsHub.com</a>

That is it. No registration, no API key, no licence fee.

Data Notes

• Salary figures are gross annual amounts in EUR. Net estimates assume a standard employee without the 30% ruling. Actual net pay varies based on personal deductions, housing benefit, and other factors.
• Rent ranges reflect the private rental market in each city as of early 2026. They exclude social housing (which has long waiting lists for most expats).
• Health insurance costs are for basic mandatory Dutch health insurance (basisverzekering). Expats on certain visa types may have different requirements.
• All amounts are in EUR.
• Data is updated when official figures change (typically January each year for tax brackets and minimum wage; quarterly for housing markets).

Questions or Corrections

If you spot an error in the data or want to request additional fields, contact us via the contact page. We will consider adding new endpoints (e.g., 30% ruling calculator output, housing by neighbourhood) if there is demand.
