A Netherlands hourly-rate calculation answers one practical question: which euro rate covers your desired net income, business costs, Dutch income tax, the self-paid Zvw contribution, and the hours you can actually declare to clients. KVK's guidance uses that structure for entrepreneurs who work with hourly rates, including zzp'ers using uurtje-factuurtje billing or hourly rates in quotes.
The denominator matters as much as the annual target. KVK starts with 1,840 available hours from 230 working days of 8 hours, then notes that a starting entrepreneur may bill only 50-60% because acquisition, networking, administration, and idea development are not invoiceable. Knab's 2026 survey reports 28 declarable hours per week as the average across Dutch zzp'ers.
Use this formula: `(net income + business costs + income tax + Zvw) ÷ declarable hours = hourly rate excluding VAT`. The Netherlands uses the euro, so keep the full calculation in euros. VAT belongs on the invoice according to the applicable VAT treatment, not inside the base income target, unless you are deliberately modeling the client-facing price including VAT.
For example, a Dutch freelancer who wants €58,000 in net income, expects €15,000 in business costs, estimates €21,250 in Dutch income tax, and adds €3,250 for the self-paid Zvw contribution needs €97,500 before VAT. With 1,300 declarable hours, the required rate is €75.00 per hour excluding VAT. That figure is a pricing base, not a complete tax return.
Dutch entrepreneurs paying income tax in 2026 face Box 1 rates of 35.75% up to €38,883, 37.56% from €38,883 to €78,426, and 49.50% above €78,426. Freelancers and entrepreneurs also pay the income-dependent Healthcare Insurance Act contribution themselves by assessment in 2026, at 4.85% on contribution income capped at €79,409.
VAT changes the invoice amount and cash flow. Dutch resident businesses generally charge VAT at 21%, 9%, or 0%. The KOR can exempt businesses with turnover below €20,000 per year from charging VAT and filing VAT returns, with no input-VAT deduction. For Dutch-only established businesses selling EU B2C digital services or distance sales, the €10,000 threshold affects whether Dutch VAT or the customer's EU country VAT applies.
A calculator is enough when you need a single Dutch hourly quote, a rough client proposal, or a quick check against Knab's 2026 average zzp rate of €83 per hour excluding VAT. It also works when your hours, costs, and tax assumptions stay stable for one engagement and the invoice structure is simple.
A managed workflow is better when several projects share one client budget, billable and non-billable work must stay separate, or recurring retainer periods need spending limits. Everhour Project Budgeting tracks hour-based and money-based budgets, recurring periods, threshold alerts, budget protection, expense inclusion controls, multiple billing methods, and client-level budgets.

The main inputs are desired net income, business costs, Dutch income tax, the self-paid Zvw contribution, and realistic declarable hours. KVK's formula uses those categories directly. VAT treatment, KOR eligibility, and the customer type affect the invoice and cash flow, but the base hourly rate usually starts before VAT.
Dutch B2B hourly quotes are commonly stated excluding VAT, then VAT is added on the invoice when the business must charge it. Dutch resident businesses generally use 21%, 9%, or 0%, depending on the supply. KOR participation changes this because eligible businesses below €20,000 turnover do not charge VAT and cannot deduct input VAT.
Use the hours you can actually bill or declare, not all working hours. KVK starts from 1,840 available hours and notes that starters may bill only 50-60% of that time. Knab's 2026 survey gives another practical benchmark: Dutch zzp'ers average 28 declarable hours per week.
The self-paid Zvw contribution is easy to miss because it sits outside the invoice rate and arrives by assessment. In 2026, freelancers and entrepreneurs pay 4.85% on contribution income capped at €79,409. A rate that covers income tax but omits Zvw understates the annual amount the freelancer needs to collect.
Wet DBA does not change the arithmetic, but it changes the assignment risk. Dutch clients and contractors must assess whether a zzp assignment is genuine self-employment. If the relationship is false self-employment, post-tax assessments can apply, and fines may apply from 2026. A long-term engagement should be checked before pricing it like independent contract work.
Everhour Project Budgeting lets teams apply hour-based or money-based budgets to Dutch client work after the hourly rate is agreed. Recurring budget periods, threshold alerts, budget protection, and client-level budgets help keep retainers and ongoing assignments aligned with the quote.
Everhour tracks billable and non-billable time through project billing status, task-level non-billable controls, custom task rates, and member-rate exceptions. Reports can show billable time, non-billable time, billable amount, and cost by member or task.
Turn a calculated hourly rate into project limits, recurring budget periods, and client-level controls. Everhour gives teams budget visibility as time and expenses accumulate against Dutch client work.
