Dutch Employer On-Costs Worksheet: Salary, Premiums, Benefits and ICS Payroll Fees

Why Gross Salary Alone Understates a Dutch Hire

A common approach is to convert an offer letter into a budget starting from the gross salary alone. In the Netherlands that leaves out the largest part of the difference between what an employee is promised and what the company actually pays out. ICS Payroll frames the problem with a worked example: a gross monthly salary of €5,000, with sick-leave insurance included, produces a total monthly cost of €8,271 in its calculator. Over a year that is about €99,256, or €59.22 per hour, at a cost factor of 1.654. Put differently, every euro of gross salary in that example carries roughly another sixty-five cents of cost around it.

The worksheet below is built to make those extra cents visible, line by line, so that a budget owner can see which numbers are fixed, which move with salary and which depend on the contract. It assumes you are hiring through an EOR like ICS Payroll, which is the situation the remote-hire route is designed for, but the same logic applies if you are only checking a quote from someone else.

The Worksheet Lines and Where Each Number Comes From

Before any arithmetic, sort every cost into one of three buckets. Some lines are a percentage of gross salary. Some are passed through at whatever they actually cost. One is a flat monthly fee for the service itself. Mixing the buckets is the most common reason two quotes for the same hire look incomparable.

Read the table from the top. Salary is yours. Burden is the statutory layer, and ICS Payroll gives a range rather than a single figure because the exact percentage depends on the facts of the case. Benefits are the discretionary layer. The fee is the only line that does not move when the salary moves.

Percentage-Based Costs: Employer Burden and Its Range

Employer burden is the cost that scales with pay. ICS Payroll puts it at about 22-28% of gross and invoices it at cost rather than adding a margin on top. The width of that range matters for budgeting. On a salary of any size, the difference between the low and high end is real money, so a careful worksheet carries two columns, one calculated at each end, rather than picking the midpoint and hoping.

The wider industry gives a similar picture. ICS Payroll notes that mandatory employer premiums typically add 20 to 30 percent to an employee's gross salary, which is a useful sanity check on any quote that seems either suspiciously light or unusually heavy. If a proposal shows a burden far outside that band, ask what has been bundled into it or left out.

Costs Billed at Cost: Benefits and Supplementary Pension

Benefits sit in their own bucket because they are not a fixed percentage of anything. ICS Payroll invoices them at cost, which means the worksheet line should be filled from the actual benefit terms in the offer, not from a rule of thumb. If the offer includes a mobility allowance, a device budget or any other agreed extra, list each one separately so that a later change to one does not disturb the rest of the sheet.

Supplementary pension deserves a careful note rather than a number. Business.gov.nl explains that supplementary pension is compulsory where an applicable collective agreement includes a compulsory pension scheme, where a sectoral pension fund is compulsory for the industry, or for certain professions with an occupational scheme. Employers must also tell employees which scheme applies and where to find pension information. The practical consequence for a worksheet is that pension cannot be filled with zero just because no collective agreement has been identified. Leave the line marked as unresolved until the sector question is answered, and only then attach a cost. For the payroll side of that question, see the guide on Dutch pension obligations.

Where the EOR Management Fee Enters the Calculation

The management fee is the easiest line to get right and the easiest to double count. ICS Payroll's remote-hire service charges €299 per employee per month, flat. Because it is flat, it should be entered once per person per month, outside the percentage calculations. It is not part of the burden and it does not grow with a raise.

Context helps when you compare providers. ICS Payroll's research shows industry-wide EOR service fees in the Netherlands ranging from €175 to over €650 per month. A wide spread like that means a headline fee tells you little until you know what sits beside it. A cheaper fee with separately itemised insurance and tax lines may cost more in total than a higher fee that covers them. The comparison that matters is the all-in monthly total for the same salary, not the fee alone.

Turning the Lines Into an Annual Budget With a Tolerance

With the buckets filled, the annual figure is straightforward: twelve months of salary, plus burden at each end of the range, plus benefits at their actual cost, plus twelve payments of the flat fee. Then apply the tolerance. ICS Payroll states that its calculator output is indicative and can deviate by plus or minus 5% depending on the facts of the case, and that a written quote confirms the exact numbers. Treat that as a design rule for your own sheet. Show a base case and a band, and do not present the base case as a promise.

ICS Payroll also states that its pricing is a fixed price with no hidden fees: one agreed rate covers payroll, taxes, insurances and its service, with no surprise line items. In worksheet terms, that is a claim you can test. Ask for the written quote, which confirms the exact figures, and check that every line on your sheet has a matching line on theirs. Any line on your sheet with no partner on the quote is a question to raise before signing. Providers vary in how they present risk cover, so the quote review is also the moment to look at the certification and liability position described in the article on SNA certification and chain liability.

Common Worksheet Errors to Catch Before Approval

A few mistakes recur. First, adding the burden percentage to a figure that already includes it, which happens when a quote's total is used as the starting salary. Second, treating the flat fee as a percentage, which understates it on low salaries and overstates it on high ones. Third, dropping benefits because they feel discretionary, even though they are invoiced at cost once agreed. Fourth, entering a single-point estimate with no tolerance, which turns a forecast into a commitment.

One item is easy to overlook when the conversation is about a mandatory versus optional payment. If the role might come with an extra month of pay through a contract or sector agreement, model it as its own line and confirm it in writing. The separate guide on whether a thirteenth month is mandatory walks through that decision. Once the sheet is complete, share it with your provider and ask for reconciliation against the quote, line by line.
