A developer with an €80,000 salary actually costs you €12,600-€15,200 per month.

Productive working time

Of 365 days per year, after subtracting weekends, vacation, holidays, and sick leave, only about 205-210 productive working days remain.

Factor out the 20% non-productive work time (meetings, admin, Slack), and you're left with 164-168 truly productive days.

Cost per productive day: €900-€1,100

Internal developer vs. Subscription

Internal

Full control and integration into the team
Long-term knowledge building in the company
Culture and identification with the product

Risks

€12,600–15,200 total monthly cost
4–6 months recruiting + 2–3 months onboarding
Downtime risk (vacation, sick leave, resignation)
30% bad hire rate within the first 12 months

The risk of a bad hire

30% of all new hires fail within the first 12 months. The cost of a bad hire:

Recruiting costs: lost (€10,000-€25,000)
Onboarding investment: lost (€13,000-€20,000)
Team productivity loss: €5,000-€10,000
Recruiting again: + another €10,000-€25,000
Total cost of a bad hire: €38,000-€80,000

Conclusion

A developer doesn't cost €80,000 per year, but €150,000-€183,000. Knowing this number enables informed decisions. Subscription development starts at €2,495/month and offers predictable costs without recruiting risk.

The question isn't whether internal hiring is more expensive. The question is whether you can afford the risk and the wait.
