"Should we hire a full-time events manager or stick with the agency?" — the question that haunts every L&D, HR, and Comms director once company headcount crosses 200. The agency costs €6k an event but feels expensive; an FTE costs €85k loaded but only makes sense if you

Quick answer: An in-house events team typically costs €60k-€110k/year per FTE in Europe. Agency fees average 10-15% of total event spend, or €4k-€12k flat per event. The breakeven is usually 5-8 events/year: below that, an agency is cheaper; above 10+, in-house wins on cost and consistency.

run 8+ events. Most companies guess. This calculator shows the real breakeven based on your specific event count, mix of internal/agency, and scope — so the decision becomes math, not vibes.

How to read your result

If breakeven is below your current event count, in-house is the long-term winner — but only if you can guarantee that volume for 18+ months (FTE recruitment + ramp). Above breakeven, agency wins on flexibility. A hybrid model (1 FTE + agency overflow at peak) often beats both in cost-per-event for 6-12 event/yr companies.

Frequently asked questions

What's a typical agency fee in Europe?

10-15% of total spend for retainer/percentage models, or €4k-€12k flat per medium-complexity event. Source: range from European MICE planner interviews.

What's a loaded FTE cost for an events manager?

€60k-€110k/year in Western Europe including salary, benefits, employer taxes, equipment, training. Junior coordinators £40k-€60k; senior managers €100k+.

Does the agency fee include hotel commission?

Many agencies also take a 5-10% commission from the hotel — this doesn't show on your invoice but inflates your rates. Ask explicitly.

When does in-house break down?

If event volume is <5/year, hiring an FTE means they're idle most of the time. If >15/year, one FTE can't keep up — you need 2 or hybrid.

Should I include software cost on both sides?

Yes — agencies pass through tools too. Use the same €2-3k/yr tool stack baseline on both sides for fairness.
