Realistic Scenarios
Scenario 1: Consistent Full-Time Work (220 days)
Employee:
- Cost: £65,000
- Available: 219 days
- Cost per day: £297
Freelancer:
- Cost: £400 × 220 = £88,000
- Employee saves: £23,000/year
Scenario 2: Part-Time Work (100 days)
Employee:
- Cost: £65,000
- Utilization: 100/219 = 46%
- Wasted cost: £35,000
Freelancer:
- Cost: £400 × 100 = £40,000
- Freelancer saves: £25,000/year
Scenario 3: Variable Work (120-180 days)
Employee:
- Fixed cost: £65,000
- Predictable
Freelancer:
- Low month (20 days): £8,000
- High month (30 days): £12,000
- Average year (150 days): £60,000
- Freelancer saves: £5,000/year with more flexibility
But Wait: Productivity Differences
Employee effective productivity: 70-80%
219 working days × 75% productivity = 164 productive days
Freelancer effective productivity: 95-100%
You only pay for work done. No meetings, no admin time.
220 freelance days = 220 productive days
Adjusted comparison:
Employee: £65,000 ÷ 164 productive days = £396/day
Freelancer: £400/day
Almost identical on a per-productive-day basis.
Quality & Expertise
Employee:
- Learns your business
- Available for ad-hoc tasks
- Builds institutional knowledge
- May lack cutting-edge skills
Freelancer:
- Brings external expertise
- Works on many projects (more experience)
- Stays current (must to stay competitive)
- Less context on your business
Management Overhead
Employee:
- Needs 5-10 hours/week of your time
- Performance reviews
- Career development
- Team integration
Your time cost: 8 hours/week × 48 weeks × £50/hour = £19,200
Adjusted employee cost: £65,000 + £19,200 = £84,200
Freelancer:
- Needs 1-2 hours/week (briefing, review)
- Self-managing
Your time cost: 2 hours/week × 48 weeks × £50/hour = £4,800
Adjusted freelancer cost: £60,000 (150 days) + £4,800 = £64,800
Freelancer is £19,400/year cheaper when you include management time.
Risk & Flexibility
Employee:
- 1-3 month notice period
- Potential tribunal risk
- Redundancy liability after 2 years
- Harder to scale up/down
Freelancer:
- Instant scale up/down
- No notice period
- No liability
- Can use multiple freelancers for peaks
The IR35 Problem
If your freelancer:
- Works only for you
- Uses your equipment
- Works your hours
- Is supervised like an employee
HMRC may classify them as "disguised employee."
Result:
- You pay employer NI (£5,644)
- Freelancer loses limited company benefits
- Effective rate increases to £520/day
New freelancer cost: £78,000/year (150 days)
Now employee is cheaper.
The Hybrid Approach
Smart businesses do both:
1 core employee (£50k, £65k true cost)
- Handles 180 days of work
- Builds culture and knowledge
Freelancers for peaks (£400/day)
- Extra 40 days for busy periods: £16,000
- Total: £81,000
vs all-freelancer:
- 220 days @ £400 = £88,000
Hybrid saves £7,000 and gives stability + flexibility.
Decision Matrix
Choose employee if:
- You need 180+ days/year consistently
- Building a team/culture matters
- Long-term projects (2+ years)
- Want someone fully invested
Choose freelancer if:
- You need <150 days/year
- Work is project-based or variable
- Want flexibility to scale
- Need cutting-edge specialized skills
Choose hybrid if:
- You need 180+ days but with variable peaks
- Want flexibility + stability
- Growing but uncertain of growth rate
The Bottom Line
Employee costs £65,000/year but provides 164 productive days = £396/day
Freelancer costs £400/day with zero overhead
Financial difference is minimal. The decision comes down to:
- Workload consistency
- Management capacity
- Flexibility needs
- Long-term vision
