Hiring your first employee feels exciting until you realize salary is just 60-70% of the actual cost. Here's everything you need to budget for.
Category 1: Direct Payroll Costs

The obvious one. What you agreed to pay them annually.
Example: £30,000/year
2. Employer National Insurance (NI)
13.8% on earnings above £9,100/year (2024-25).
Example: (£30,000 - £9,100) × 13.8% = £2,884/year
3. Pension Contributions
Minimum 3% employer contribution (usually on qualifying earnings £6,240-£50,270).
Example: £30,000 × 3% = £900/year
Many employers offer 5-10% to be competitive.
4. Statutory Costs
- Sick pay (if applicable)
- Maternity/paternity pay
- Holiday pay accrual (5.6 weeks = 10.8% of salary)
Example holiday cost: £30,000 × 10.8% = £3,240/year

One-off cost, amortized over expected tenure (2-3 years):
£5,000 ÷ 2 years = £2,500/year
19. Onboarding & Training
First month is typically 50% productive while they learn.
Cost: £30,000 salary ÷ 12 months = £2,500 × 50% loss = £1,250 one-off

20. Management Time
You (or a manager) will spend 5-10 hours/week managing this person.
Example: Your time is worth £50/hour.

*This is the hidden cost people forget.*
Running total: £60,761/year

A £30k employee actually costs you ~£60k when you include everything.
*That's 2× the salary.*
What If You Skip Some Costs?
Bare minimum (no benefits, no office, minimal setup):
£30,000 + £2,884 (NI) + £900 (pension) + £3,240 (holiday) = £37,024
This is ONLY if:
- They work from home (their own equipment)
- No benefits beyond statutory minimum
- You handle payroll yourself
- You don't value your management time
Even the "cheap" option is 23% more than salary.
Break-Even Calculation
If this employee costs £60,000/year, how much revenue must they generate?
At 30% profit margin: £60,000 ÷ 0.30 = £200,000 revenue
At 50% profit margin: £60,000 ÷ 0.50 = £120,000 revenue
Your new hire must generate 2-4× their salary cost in revenue just to break even.
Should You Hire?
Hire if:
- You have consistent revenue to support £60k annual cost
- You're turning down work because you're too busy
- You can afford 6-12 months of losses while they ramp up
- The role generates clear revenue or saves you time worth >£60k
Don't hire if:
- Revenue is unpredictable
- You're hoping they'll "bring in clients"
- You can't afford 6 months of payroll if sales drop
- You could outsource the work for less
Alternative: Contractor at £400/day
2 days/week = £800/week = £38,400/year
No benefits, NI, equipment, or management overhead.
Often cheaper and more flexible than hiring.
The Bottom Line
Budget 1.8-2.0× the salary to cover the true cost of employment.
If you're thinking "I'll just pay them £30k," you're actually committing to £54k-£60k/year.
Plan accordingly. Many businesses fail because they underestimate employment costs and run out of cash.
