Employee vs Contractor: Which Costs Less?
By James Blanckenberg · Published May 11, 2026
Hire an employee or contract a freelancer? The contractor's day rate is always higher, so freelancers look more expensive. Once you account for the real cost of an employee — taxes, benefits, equipment, ramp time — the answer often flips. Here's the side-by-side.
Apples-to-apples scenario
A growing London-based product company needs senior frontend development for an upcoming launch. Two paths:
- Hire a senior frontend engineer on £75,000 salary
- Contract a senior freelance frontend at £600/day
Employee true cost (annual)
| Gross salary | £75,000 |
| + Employer NIC (13.8%) | £9,094 |
| + Pension (5%) | £3,750 |
| + Private medical, life, perks | £1,500 |
| + Equipment / software / training | £2,500 |
| + Office desk allocation | £3,500 |
| + Hiring cost (recruiter fee 15%) | £11,250 |
| Year-1 total | £106,594 |
| Year-2 onward (no recruiter) | £95,344 |
Contractor true cost (annual equivalent)
At £600/day, full-time-equivalent (220 working days/year) = £132,000 if used continuously. But contractors rarely work full-time-equivalent for a single client. Real scenarios:
| Engagement | Days/year | Annual cost |
|---|---|---|
| 3-day/week engagement | ~150 | £90,000 |
| Full-time-equivalent for 6 months | ~110 | £66,000 |
| Project basis (~4 months total) | ~80 | £48,000 |
No employer NIC, no pension, no medical, no office desk, no long-term commitment.
Verdict by scenario
| Need | Cheaper option | Why |
|---|---|---|
| Ongoing 5-day-a-week role for 2+ years | Employee | Daily contractor cost compounds; employee cost flattens |
| 3-day/week for ≤18 months | Contractor | Avoids the £30k+ overhead premium |
| Specialist skill needed for 4 months | Contractor | Hiring + ramp time exceeds project length |
| Permanent specialist role | Employee | Continuity, institutional knowledge, no rate inflation |
| Uncertain workload | Contractor | Easy to ramp up/down without redundancy costs |
The break-even calculation
Rule of thumb: a contractor at day rate £X equals an employee at roughly £X × 130 salary (year 1). So £600/day ≈ £78,000 salary equivalent for a year of continuous engagement, accounting for all the employee overheads.
Employee-equivalent salary ≈ Contractor day rate × 130
£600/day × 130 = £78,000 salary equivalent
£500/day × 130 = £65,000 salary equivalent
£400/day × 130 = £52,000 salary equivalent
Non-cost factors
- Commitment / loyalty. Employees stay; contractors leave when the project ends.
- Institutional knowledge. Long-term employees know the "why" behind decisions.
- Flexibility. Contractors scale up/down without redundancy procedures.
- Risk allocation. Contractors absorb their own sick leave, holidays, equipment failures.
- IR35 risk (UK). Disguised employment can attract back-taxes if the engagement looks too employee-like.
Run your own numbers
Use the Employee Cost Calculator to compute the all-in cost of a hire, then compare against contractor day rate × expected days/year for an apples-to-apples comparison. The Freelance Rate Calculator shows what the contractor needs to charge to cover their own overheads.
Bottom line
- Employee true cost is ~130% of salary; contractor headline rate is the full cost.
- For continuous 2+ year roles, employees usually win on cost.
- For specialist, project-based, or uncertain workloads, contractors win.
- Day rate × 130 = rough employee-salary-equivalent break-even.
