What it costs per month

A fractional CMO is usually priced per day. A simple way to estimate the monthly cost is: day rate × days per week × 4.33 weeks. Rounded to the nearest €100:

Day rate	1 day a week	2 days a week	3 days a week
€690 (Phil Ruttens, starting rate)	about €3,000	about €6,000	about €9,000
€1,000	about €4,300	about €8,700	about €13,000
€1,300	about €5,600	about €11,300	about €16,900
€1,600	about €6,900	about €13,900	about €20,800

Holidays, a lighter month or a fixed monthly retainer can change the real total. VAT comes on top for business clients.

Fractional, interim or permanent: how the cost compares

Fractional CMO: you pay for one to three days a week. The cost scales with the time you actually need, and you can review it at set intervals.
Interim CMO: close to full-time for a fixed period, often three to twelve months. Higher monthly cost, but no recruitment fee, notice period or severance.
Permanent CMO: a full-time salary plus employer costs, recruitment fees and months to hire. In the Netherlands, DWDA puts a full-time CMO at €140,000 to €200,000 a year including employer costs (source).

What drives the price

Days per week: the biggest factor. One day a week suits direction and decisions; two to three days suit a team that also needs hands-on leadership.
Scope: owning strategy only costs less than owning strategy, team and execution.
Interim or fractional: an interim mandate is closer to full-time and usually priced higher per month.
Sector and complexity: deep-tech, regulated or international markets tend to sit at the top of the range.
Direct or via an agency: an interim firm adds its margin to the day rate.
Location and travel: on-site days far from the consultant's base can add travel time or costs.
