The verdict in three sentences
The headline day rate says nothing about total cost of ownership: an in-house developer on a 45,000 EUR salary actually costs 65,000 to 75,000 EUR/year including charges and management. On a 3-to-6-month project, the outsourced agency is often 30 to 50 % cheaper than in-housing while removing recruitment risk. The real trade-off is duration: beyond 18 months of continuous load, in-house becomes competitive again.
Day rate and hidden costs per model
Comparing gross day rates is misleading. Here are the 2026 ranges and what they hide.
| Model | Day rate / daily cost | Hidden costs | Start-up time |
|---|---|---|---|
| In-house hire | 300-350 EUR equiv. | 45 % charges, turnover, management | 8-12 weeks |
| Freelancer | 350-700 EUR | Bus factor, availability, VAT | 1-3 weeks |
| France agency | 500-900 EUR | Margin, less flexibility | 2-4 weeks |
| Nearshore agency | 250-500 EUR | Coordination, quality audit | 1-2 weeks |
The equivalent daily cost of an in-house hire (loaded salary / working days) is around 300-350 EUR, but recruitment, training, leave and departure risk add on top.
TCO on a 100 person-day project
Typical project: a business application, 100 person-days over 5 months. 2026 orders of magnitude.
| Item | In-house | Freelancer | France agency | Nearshore |
|---|---|---|---|---|
| Production cost | 34,000 EUR | 52,000 EUR | 70,000 EUR | 38,000 EUR |
| Recruitment / sourcing | 8,000 EUR | 500 EUR | 0 EUR | 0 EUR |
| Management / coordination | 6,000 EUR | 4,000 EUR | 2,000 EUR | 3,000 EUR |
| Risk / rework | 5,000 EUR | 6,000 EUR | 2,000 EUR | 3,000 EUR |
| Estimated TCO | 53,000 EUR | 62,500 EUR | 74,000 EUR | 44,000 EUR |
For a one-off need, nearshore and in-house come out ahead, but in-house assumes a lasting need to amortise recruitment. The freelancer stays flexible but exposes you to the bus factor.

FAQ
Is outsourcing always cheaper?
Not in the long run. For a continuous need beyond 18-24 months, an in-house team ends up cheaper. Outsourcing wins on one-off projects and load peaks.
How do I avoid the bus factor with a freelancer?
Require up-to-date documentation, repository access and ideally a second contact. A lone freelancer remains a single point of failure on a critical project.
What criteria beyond price?
Real seniority, verifiable references, contractual clarity on intellectual property, post-delivery maintenance capacity and communication quality.
Fixed-price or time-and-materials?
Fixed-price secures the budget on a defined scope; time-and-materials suits evolving needs. A poorly scoped fixed-price project generates costly change orders.
