Most owners hire on a feeling. The team is stretched, a good candidate turns up, and the salary looks affordable against last month’s sales.
Six months later payroll is up. The owner is working the same hours. Nobody can say for certain whether the new person has paid for themselves.
Here is the real cost of employing someone in the UK in 2026, built up line by line. Every rate comes from HMRC or gov.uk pages current at the time of writing. Then comes the part most guides skip: the margin maths. It tells you what gross profit the role has to generate, and by when. Use it as a template and put your own numbers in.
The statutory layer: what every employer pays in 2026/27
Start with the costs set by law. Owners get these wrong most often, because they remember an older year.
Employer National Insurance. HMRC’s rates and thresholds for employers 2026 to 2027 put employer Class 1 National Insurance at 15%. It’s charged on earnings above the secondary threshold of £96 a week, £417 a month or £5,000 a year. On a £32,000 salary that’s 15% of £27,000. So £4,050 a year.
Employment Allowance. The same HMRC page sets the Employment Allowance for 2026/27 at £10,500, offset against your total NI bill. Gov.uk’s eligibility guidance says that since April 2025, employers with more than £100,000 of Class 1 liabilities can also claim. In a firm of five to fifty people, the existing team usually uses up the allowance already. So a new hire carries the full 15%.
Auto-enrolment pension. Gov.uk’s workplace pension guidance sets the minimum total contribution at 8% of qualifying earnings. The employer pays at least 3% of that. The Department for Work and Pensions’ review for 2026/27 keeps the qualifying band at £6,240 to £50,270. On £32,000, the employer’s 3% applies to £25,760. That’s £772.80 a year. If your scheme pays more, use your own rate.
National Living Wage. HMRC’s page gives the rate from April 2026 as £12.71 an hour for workers aged 21 and over, and £10.85 for 18 to 20 year olds. On a 37.5-hour week, £12.71 comes to roughly £24,800 a year. That’s the floor for a full-time adult hire.
Holiday. Gov.uk’s holiday entitlement guidance gives full-time workers 5.6 weeks of paid leave a year. That’s at least 28 days on a five-day week, and bank holidays can count within it. Holiday sits inside the salary. What it changes is how many working days you get for the money.
Sick pay. HMRC’s April 2026 Employer Bulletin covers absences starting on or after 6 April 2026. Statutory Sick Pay is now paid from the first full day. The rate is 80% of average weekly earnings or £123.25 a week, whichever is lower, and the lower earnings limit has gone. Employers fund it themselves.
The costs that never appear on a payslip
The statutory layer is the easy part. The costs below are where an “affordable” salary quietly grows by a third. There are no official rates for these, so use your own figures.
- Recruitment. Job board fees. An agency percentage if you use one. Days of senior time reading CVs and interviewing.
- Equipment and software. Laptop, phone, tools or vehicle access. A seat on every system the business runs. Licences are per head and recur monthly.
- Space and overhead. A desk, or a share of the workshop, van, insurance and utilities.
- Training and management. Induction, compliance training, and the manager hours spent answering questions and checking work in the first quarter.
- The ramp-up period. Full salary from day one. Full output later. The gap between those two lines is a real cost. In most established businesses it’s the biggest hidden one.
The real cost of employing someone: a £32,000 hire, line by line
Here’s the build-up for one full-time employee on £32,000 in 2026/27. The statutory lines use the rates above. Every other line is an illustrative round number. Swap in your own.
| Cost line | Basis | Year one |
|---|---|---|
| Salary | Agreed | £32,000 |
| Employer NI | 15% on £32,000 minus £5,000 (statutory) | £4,050 |
| Employer pension | 3% on £32,000 minus £6,240 (statutory minimum) | £773 |
| Payroll cost | £36,823 | |
| Recruitment | Illustrative: adverts plus senior time | £3,000 |
| Equipment | Illustrative: laptop, phone, kit | £1,500 |
| Software licences | Illustrative: £100 a month | £1,200 |
| Desk and overhead share | Illustrative: £200 a month | £2,400 |
| Training and induction | Illustrative: courses plus manager time | £1,000 |
| Cash cost, year one | £45,923 |
So a £32,000 salary is a £45,900 commitment in year one. That’s roughly 43% above the headline.
From year two the one-off lines drop away. The running cost settles at around £40,400, still 26% above salary.
Now the days. A five-day week gives about 260 working days a year. Take off 28 days of holiday and a few for sickness and training. A realistic figure is around 225 productive days. Divide the payroll cost by that and each productive day costs about £164.
Then the ramp-up. Say, for illustration, three months at half output. That’s a quarter of the year at 50%, or about six and a half weeks of payroll. Roughly £4,600 paid for output that never arrived.
Add that to the cash cost. The effective year-one investment is close to £50,500, for roughly nine months of full contribution.
The margin maths: what the role has to generate, and by when
Gross profit pays for a new employee. That’s what’s left after the direct costs of delivering the work.
A pound of extra revenue covers a pound of cost only once materials, subcontractors and other direct costs have come out of it.
Take the example above in a business running a 40% gross margin. That’s common in trades, professional services and light manufacturing. The role needs to add £50,500 of gross profit in year one to stand still.
At 40%, that’s about £126,000 of extra revenue. Roughly £14,000 a month once the person is up to speed. At a 60% gross margin the revenue hurdle falls to around £84,000. At 25% it rises to just over £200,000.
Three things follow.
- Set the hurdle before the advert goes out. Write down the gross profit the role must generate, in pounds, by month six and month twelve. If you can’t see where that number comes from, the hire is a hope.
- Know your gross margin per role. The same salary is a comfortable decision at 60% and a hard one at 25%. Owners who only watch overall net profit misjudge this all the time.
- Price support roles in owner hours. An administrator or coordinator pays for themselves by freeing up the owner or a senior fee-earner. Say a £36,800 payroll cost frees 15 hours a week of an owner whose time is worth £150 an hour. That’s about £108,000 a year of capacity. The question is what you’ll do with those hours.
What the Employment Rights Act changes for a small employer
The Employment Rights Act 2025 received Royal Assent on 18 December 2025. It’s being switched on in stages. The cost of getting a hire wrong is about to rise, so it pays to know what’s live and what’s coming.
In force since 6 April 2026, according to HMRC’s April 2026 Employer Bulletin: Statutory Sick Pay from day one, with the lower earnings limit removed. Paternity leave and unpaid parental leave from the first day of employment. A new bereaved partner’s paternity leave.
Pinsent Masons’ implementation timeline, updated 1 September 2026, adds a holiday record-keeping duty and the Fair Work Agency from the same date.
Scheduled for October 2026, per the same timeline: employment tribunal time limits extended from three months to six, and a stronger duty to prevent workplace harassment.
Scheduled for 1 January 2027, confirmed in both sources: the qualifying period for unfair dismissal falls from two years to six months. The compensation cap is removed. New protections against fire and rehire take effect. Measures on zero-hours and low-hours contracts, flexible working, bereavement leave and collective redundancy are due later in 2027.
For a small business, the six-month unfair dismissal period is the big one. From January 2027, a hire who is wrong for the role has to be spotted, managed and, if necessary, exited through a fair process inside six months. That puts a hard deadline on ramp-up.
This is the position as at September 2026. Check it with an employment adviser before you act.
The hire is usually right. The structure around it is usually missing
Owners in Liverpool and across the North West tell us “we hired and it made no difference”. The decision to add a person was almost always sound. What was missing was the structure that turns a salary into a return.
A KPI for the role. One number, reviewed weekly, that tells everyone whether the role is doing its job. Jobs completed. Quotes converted. Invoices raised within 48 hours. Owner hours released. Most new roles start without one.
A one-page job scorecard. The purpose of the role in one sentence. The three to five outcomes it exists to deliver. The KPI. Write it before you recruit, use it at interview, and review it at 30, 60 and 90 days. With a six-month qualifying period on the way, it’s also your evidence that expectations were clear from day one.
An onboarding plan. Who trains them, on what, in which week, and what “fully effective” looks like. This is what shortens ramp-up. In the example above, taking it from three months to six weeks is worth over £2,000 on its own.
Building that structure is the team and systems part of our business coaching programmes. Define the outcome the role serves. Give it a scorecard and a number. Then build the systems so the business runs on the team’s output.
In 1-2-1 coaching, the scorecard for a new role is often the first document we write together. Alexander Myerson & Co, a Liverpool accountancy practice, grew net profit by 80% in 15 months working this way on pricing, team and systems. Individual results vary.
Before the advert goes live
Employing someone in 2026 is a £46,000 decision on a £32,000 salary, before ramp-up.
Build the cost line by line. Write down the gross profit the role has to generate by month six and month twelve. Give the role a scorecard and a KPI before you advertise.
Then look back at your last hire. What gross profit should that role have added by now?
