In-House vs Outsourced SDR Cost Calculator (Benelux)
What an SDR really costs in Belgium and the Netherlands once you add employer charges, tools, recruitment, ramp time, and management. Then compare it to an outsourced program, month by month.
Want Benelux pipeline without the headcount?
We run outbound for B2B software companies growing in Belgium and the Netherlands with native senior SDRs. No recruitment, no scarce-talent hunt, no management load. You get meetings, not a hiring project.
What this calculator does
This tool shows the true cost of an in-house SDR in Belgium and the Netherlands and compares it to an outsourced sales program over 18 months. Salary alone is a poor guide. It leaves out employer charges, tools, recruitment, management, and the ramp period where you pay full cost for partial output. In Benelux the employer charges in particular are among the highest in Europe.
What an SDR really costs in Benelux
Belgium has some of the heaviest employer social charges on the continent, around 27% for white-collar staff. The Netherlands is lighter at roughly 20%, but Dutch hiring leans heavily on contractors, which changes the cost and flexibility picture. We use 25% as a Benelux mid-point.
Why the salary-vs-fee comparison is misleading
1. Belgian charges are among the highest in Europe
At around 27% for white-collar employees, Belgian employer charges turn a 60,000 package into roughly 76,000 before tools or management. An agency fee already has the equivalent built in.
2. The Netherlands trades charges for contractor complexity
Dutch employer charges are lower, but much of the market runs on contractors (ZZP). That looks cheaper until you account for the lack of commitment, the chain rules around fixed-term contracts, and the transition payment owed on dismissal.
3. You pay full cost during the ramp
A new SDR takes three to five months to reach full productivity. Salary, charges, and tools run at 100% the whole time. An outsourced team with the process already built starts producing in four to eight weeks.
4. These are small markets with scarce talent
Belgium and the Netherlands are small. Finding native SDRs who can sell in Dutch, French, and English is hard, which lengthens hiring and pushes up cost. An agency that already has the people removes that bottleneck.
When in-house still makes sense
In-house gives you focus and full-time dedicated capacity. If Benelux is your core market and you can find and keep the talent, building can work. Outsourcing tends to win when you want speed, when native multilingual coverage is the blocker, or when you would rather buy pipeline than fight a tight labour market.
Frequently asked questions
Why blend Belgium and the Netherlands?
Most companies treat Benelux as one region for go-to-market. The charge rates differ, Belgium around 27% and the Netherlands around 20%, so we use 25% as a working mid-point. Adjust the salary input to match the country you are hiring in.
What about Dutch contractors?
Hiring a ZZP contractor in the Netherlands shifts cost and risk. It can lower employer charges but reduces commitment and runs into tightening rules on contractor status. The comparison here assumes an employed SDR, which is the like-for-like against an agency program.
What outsourced monthly cost should I use?
Enter the retainer you would pay per equivalent unit. A senior SDR program targeting Benelux typically runs 3,500 to 5,000 per month. Use a real quote if you have one.
Does outsourced really start faster?
When the agency has native Benelux callers and knows your kind of sale, yes. Meetings can start in four to eight weeks against three to five months for a fresh hire.
Where do these numbers come from?
Salary ranges come from Benelux market data. Charge rates come from current Belgian and Dutch employer contribution guidance. The cost structure and ramp timelines come from the Profitbl whitepaper and from running these campaigns for clients.
