At a glance

An employee on a £55,000 gross salary costs your business significantly more than their headline pay:

3% pension	5% pension	8% pension
Employer NI	£7,500	£7,500	£7,500
Pension	£1,320.9	£2,201.5	£3,522.4
Total cost	£63,820.9	£64,701.5	£66,022.4
Above salary	16.0%	17.6%	20.0%
Cost per hour	£32.73	£33.18	£33.86

At £55,000, pension qualifying earnings are capped at £50,270, so the pension contribution is lower as a percentage than for lower salaries. However, employer NI (with no upper cap) is the dominant on-cost.

Employer National Insurance: £7,500

Employer NI is charged at 15% on all earnings above the Secondary Threshold of £5,000:

• Earnings above threshold: £55,000 - £5,000 = £50,000
• Employer NI: £50,000 x 15% = £7,500
• Monthly employer NI: £625

This is an effective rate of 13.6% on the gross salary. Unlike employee NI, there is no upper earnings limit for employer NI — it's a flat 15% on everything above £5,000.

Pension auto-enrollment: £1,320.9

UK employers must auto-enroll eligible workers into a workplace pension. The minimum employer contribution is 3% of qualifying earnings.

Qualifying earnings are the portion of salary between £6,240 and £50,270:

• Qualifying earnings (capped): £50,270 - £6,240 = £44,030
• 3% contribution: £44,030 x 3% = £1,320.9/year

Qualifying earnings are capped at £50,270, so the pension contribution doesn't increase for higher salaries. At 5%, this would be £2,201.5/year. At 8%, £3,522.4/year.

Monthly and hourly cost

Period	Salary	+ NI	+ Pension	Total cost

Weekly	£1,057.69	£144.23	£25.4	£1,227.33

Based on 1,950 working hours per year (37.5 hours/week), the cost per hour is £32.73. This is the figure to use when pricing projects or comparing against contractor day rates.
