Contractor vs Permanent Salary: Which is Better in 2025?
One of the most common career decisions UK professionals face is whether to work as a contractor or take a permanent role. This guide compares both options from a financial perspective.
The Basic Comparison
Permanent employees get a salary with benefits, job security, and paid leave. Contractors typically earn higher daily rates but don't get paid holidays, sick leave, or pension contributions from their clients.
Converting Day Rate to Annual Salary
A general rule of thumb: multiply your day rate by 220 (approximate working days per year accounting for holidays and bank holidays).
- £300/day: ~£66,000 per year equivalent
- £400/day: ~£88,000 per year equivalent
- £500/day: ~£110,000 per year equivalent
- £600/day: ~£132,000 per year equivalent
Tax Differences
Contractors often pay tax differently than employees:
- Inside IR35: You're taxed similarly to an employee through your limited company or umbrella company
- Outside IR35: You can pay yourself a mix of salary and dividends, potentially reducing your tax bill
- Dividend tax: Outside IR35, profits taken as dividends are taxed at 8.75% (basic rate), 33.75% (higher rate), or 39.35% (additional rate)
Benefits to Consider
Permanent roles typically include:
- Pension contributions: Typically 3-8% employer contribution
- Paid holiday: 28 days minimum including bank holidays
- Sick pay: Statutory Sick Pay after 3 days
- Maternity/Paternity pay
- Training and development
- Job security
Making the Decision
When comparing a contract rate to a permanent salary, remember to:
- Subtract 20-30% from your contract income for holidays, sick days, and bench time
- Add the value of benefits (typically 15-25% of salary) to the permanent side
- Consider the tax implications of your contracting structure
- Factor in pension contributions and other long-term benefits
A contract rate of £400-500/day is roughly equivalent to a permanent salary of £60,000-80,000 when all factors are considered.
