Dutch Subsidiary Costs Calculator | American Budget vs Netherlands Reality for 30-Person Team

TL;DR

Your US budget template misses 8-12 mandatory Dutch cost categories that total EUR 896,000/year for a 30-person team -- a 37% phantom cost layer above gross payroll. The correct employment cost multiplier is 1.45-1.55x gross salary, not the 1.25-1.35x American templates assume. That gap is EUR 330,000/year on a EUR 1.65M wage bill.

The American Assumption

Your US budget template -- salary, health insurance, 401(k), payroll tax, office, IT -- captures total Dutch subsidiary costs with an 8-15% international adjustment factor.

The Dutch Reality

The American template misses 8-12 mandatory Dutch cost categories entirely. Holiday allowance, pension contributions at 2-4x the US assumption, uncapped 2-year sick leave insurance, mandatory severance reserves, and five compliance vendors add a phantom cost layer of approximately EUR 896,000 annually for a 30-person team.

The Consequence

The correct multiplier for total Dutch employment cost is 1.45-1.55x gross salary, not the 1.25-1.35x that US templates assume. The difference on a EUR 1,650,000 wage bill is EUR 330,000 per year.

Phantom cost layer

Approximately 37% of gross payroll in costs that American budget templates simply miss

When an American CFO builds a budget for a 30-person Dutch subsidiary, they use the only template they know: the US one. That template has rows for salary, health insurance, 401(k) match, payroll tax, office lease, and IT. It produces a tidy number. The actual Dutch cost comes in significantly higher -- not because of extravagance or mismanagement, but because of rows that do not exist on the American spreadsheet.

The American template typically misses 8--12 mandatory Dutch cost categories entirely. Holiday allowance alone (8% of gross, not included in salary) adds EUR 192,000/year for a 30-person team at EUR 80K average. Dutch pension obligations run 2--4x the US 401(k) match assumption. Sick leave exposure is uncapped for 2 years per employee. Severance is mandatory and formula-based. The total "phantom cost" layer -- costs with no US budget row at all -- runs approximately EUR 896,000 annually for a 30-person team, representing roughly 37% of gross payroll.

The 30-Person Comparison

US-template budget: EUR 4,053,000 (including an 8% "international adjustment")

Dutch reality budget: EUR 4,258,928 (rebuilt with proper per-tier salary capping and 2026 rates per Staatscourant 2025-42324)

Gap: EUR 205,928 (5.1%) -- modest because the US template includes EUR 540,000 for health insurance (only EUR 133K in NL), EUR 184K for FICA (no NL equivalent), and EUR 63K for dental/vision (not an NL employer cost). The real story is the phantom costs.

Seven Structural Reasons the Gap Persists

The US health insurance line item creates a false sense of parity
At-will employment eliminates severance from the American mental model
The 401(k) match anchors pension expectations at 5%
US disability insurance is cheap because risk is externalized
The "parent umbrella" assumption fails for insurance and audit
Dutch payroll complexity demands specialist processing at 2--3x US cost
The "international adjustment factor" is a guess (8--15%), not the engineering the problem requires (37% of gross payroll)

Quick-Reference Cheat Sheet

Budget total employer cost at 1.40--1.55x gross salary. For EUR 80,000 gross, budget EUR 112,000--124,000. Add fixed overhead of EUR 100K--200K/year for compliance infrastructure. Buy verzuimverzekering immediately. Reserve for severance from day one.
