When most employers think about hiring costs, they focus on the salary. But the true cost of bringing someone on board includes recruitment expenses, statutory obligations, equipment, training, and ongoing overhead. For many businesses, the first-year cost of a new hire is 30-50% above the salary figure.
Understanding these costs helps you budget accurately and make informed decisions about when and how to grow your team. Use our employee cost calculator for instant figures on the statutory costs.

Before an employee starts, you will typically incur significant recruitment expenses:
Recruitment Method
Typical Cost
Job board advertising (Indeed, Reed)
£200-£500 per posting
LinkedIn job posting
£300-£700
Specialist job boards
£500-£2,000
Recruitment agency fee
15-25% of annual salary
Internal time (screening, interviews)
15-30 hours of management time
Background/DBS checks
£25-£60
Using a recruitment agency for a £30,000 role could cost £4,500-£7,500 in fees alone. Even without an agency, expect to spend £500-£2,000 on advertising and several days of management time.
Software licenses: Microsoft 365, Slack, industry tools — £500-£2,000/year
Induction training: 1-4 weeks of reduced productivity
Mentor/buddy time: senior staff hours spent supporting the new hire
Training courses: £500-£3,000 for professional development
Research suggests it takes 3-6 months for a new employee to reach full productivity. The cost of this ramp-up period is often overlooked in hiring budgets.

The year 1 cost is significantly higher due to one-off recruitment and setup costs. From year 2 onwards, expect the ongoing cost to be approximately 15-20% above salary.
A bad hire can be extremely expensive. Industry estimates suggest a failed hire costs 1.5-3x the annual salary when you factor in:
Wasted recruitment fees
Training and onboarding costs
Lost productivity during the role being vacant
Impact on team morale
Potential legal costs if dismissal is disputed
Repeating the entire recruitment process
Some businesses consider using freelancers or contractors instead. Here is a comparison:

Be aware of IR35 rules: if HMRC determines that a contractor is effectively an employee (based on control, personal service, and mutuality of obligation), both parties may face significant tax liabilities.
Claim Employment Allowance: save up to £10,500 on your NI bill. See our Employment Allowance guide for details
Use salary exchange for pensions: save NI for both employer and employee on pension contributions
Hire apprentices or under-21s: no employer NI on earnings up to £50,270
Recruit directly: using your own networks, LinkedIn, and employee referral schemes can save thousands in agency fees
Invest in retention: keeping existing staff is far cheaper than replacing them
As a general rule, hiring makes sense when:
You have consistent, ongoing work that justifies a permanent role
The revenue generated by the employee exceeds their total cost (not just salary)
You need more control over the work than a contractor arrangement allows
The role requires significant company-specific knowledge or training
For project-based or short-term work, contractors may be more cost-effective despite higher day rates, as you avoid NI, pension, holiday pay, and equipment costs.
Key Takeaways
Year 1 hiring costs are typically 30-50% above salary
Ongoing costs (year 2+) settle at 15-20% above salary
Recruitment agency fees (15-25% of salary) are the biggest one-off cost
Employment Allowance can eliminate NI for small employers
A bad hire costs 1.5-3x the annual salary — invest in getting recruitment right
