The Real Cost of Your Next Hire
The short answer: the cost of hiring an employee in the UK is roughly 1.4 times their salary in the first year. A £50,000 hire comes to about £70,500 once you add employer’s National Insurance, pension, a recruitment fee and equipment, before you count anyone’s time spent training them or the months before they’re fully productive.
The short version
- A £50K salary costs about £70,500 in year one: £6,750 employer NI, about £1,310 minimum pension, a £10,000 recruitment fee and around £2,500 of kit.
- New hires usually do a quarter to a half of the job in their first couple of months, and take three to six months to reach full speed.
- Notice periods push start dates back, often by a quarter, and any revenue planned on the back of the hire slips with them.
- Fee earners pay back fastest, sales hires slowest (often nine to twelve months), and capacity hires only if someone more expensive actually stops doing the work.
- Before signing off a hiring plan, work out the month each hire covers its monthly cost, and whether your cash can carry the gap until then.
Some time in the next few weeks, a line will go into your 2027 budget that reads something like “Account Director, £50K, from April”. It looks like a decision that’s been made. There’s a salary and a start date, and everyone round the table nods.
That £50K is the smallest number the hire will ever cost you. Once you’ve paid the recruiter, the payroll taxes and the pension, bought the laptop and found someone with time to train them, the first year comes to something closer to £70K. And for the first few months you’ll be paying full whack for someone doing a fraction of the job, because nobody arrives knowing your clients, your systems or the way you do things.
None of that is a reason not to hire. But a hire is an investment with a payback period, and if you budget it as a salary, you’ll find out about the difference in your bank balance rather than in your plan.
What is the true cost of hiring an employee on £50,000?
Here’s the first-year bill for a £50K salary in 2026/27, using the legal minimums and a fairly ordinary recruitment fee:
| Cost | How it’s worked out | Year one |
|---|---|---|
| Salary | £50,000 | |
| Employer’s National Insurance | 15% on pay above £5,000 | £6,750 |
| Employer pension | 3% legal minimum on qualifying earnings (£6,240 to £50,270) | about £1,310 |
| Recruitment fee | 20% of salary (agencies typically charge 15% to 25%) | £10,000 |
| Laptop, phone, licences and kit | Estimate | around £2,500 |
| Total | About 1.4 times salary | about £70,560 |
That’s before anyone else’s time has been counted. If you pay pension on full salary, offer health cover or pay a bonus, it goes higher. And for most businesses your size, the Employment Allowance was used up long ago, so it won’t take the edge off the NI. (Rates from HMRC’s rates and thresholds for employers 2026 to 2027 and the automatic enrolment thresholds for 2026/27.)
Then there’s the cost nobody invoices you for. Someone has to show the new person how things work, and that’s usually one of your best people rather than one of your spare ones. Four hours a week from a senior manager for the first three months is over fifty hours that would otherwise have gone on clients.
How long before a new hire is fully productive?
The bigger cost is the ramp. A new hire is usually doing somewhere between a quarter and a half of the job in their first couple of months, and it’s often three to six months before they’re doing all of it. Senior roles take longer, because there’s more to learn before their judgement is worth much.
Then put the notice period in front of that. The person you agree to hire in January often starts in April, and that gap catches out more budgets than anything else I see. Any revenue you planned on the back of the hire slips by a quarter with it.
How does each kind of hire pay for itself?
When our CFOs build a headcount plan into a budget, the first question for each role is which of three kinds of hire it is, because they pay back in very different ways.
Fee earners. These are people whose time you bill: consultants, account managers, engineers on client work. They pay back fastest because the arithmetic is simple, billable days a month multiplied by the rate you actually achieve. A £50K fee earner billing twelve days a month at £600 a day covers their monthly cost comfortably once they’re up to speed. If you can’t name the clients whose work they’ll be doing, it isn’t a fee-earning hire yet. (For agencies and consultancies, people costs as a share of fee income is the number to watch.)
Sales hires. These take longest, and they’re where hiring plans most often go wrong. On top of the ramp there’s the sales cycle. If your deals take four months to close, a new salesperson won’t bring in a pound of margin until month six or seven at the earliest. Budget for nine to twelve months before a sales hire covers their cost, and make sure you have the cash to wait that long.
Capacity hires. Operations, finance, HR, an office manager. They don’t bring revenue in. They pay back by taking work off someone more expensive, and very often that someone is you. It only works if the more expensive person actually stops doing the work. A capacity hire pays for itself in hours released, so decide in advance whose hours, and what those hours will go on instead.
How hiring plans go wrong
A few versions of this come up again and again.
The sales hire is budgeted to bring in new revenue from the second quarter. They start in April because of their notice period, close their first proper deal in October, and are let go in November for not working out, when it was the plan that didn’t work.
The senior hire is brought in to sort out the mess, with no time set aside to bring them up to speed. They spend their first six months rediscovering things the founder could have told them in a fortnight.
The operations manager is hired to free up the founder, who carries on approving every purchase order anyway. The business is now paying twice for the same work, and the founder is still working on Sunday nights.
And if the hire was made on the back of one unusually good month, Next’s approach to a good summer is worth reading first.
Six questions before you sign off your 2027 hiring plan
Take the next hire in your plan and give it ten minutes with these questions, in this order:
- What will they cost in their first year, all in? Start with the salary times 1.4 and adjust from there.
- Which of the three kinds of hire are they?
- When will they actually start, once they’ve worked their notice? Move the start date in your budget to match.
- How many months until they’re fully up to speed, and who is going to train them?
- In which month does what they bring in, or free up, cover what they cost each month?
- Can your cash carry the gap until they’ve earned back everything you spent getting there?
People tend to stop at question five. But the month a hire covers their own cost and the month you’ve earned back the recruiter, the kit and the slow early months can be a year apart, and your bank balance feels every month in between.

Frequently asked questions
How much does it cost to hire an employee in the UK?
As a rule of thumb, budget about 1.4 times the salary for the first year. On a £50,000 salary in 2026/27 that is around £70,500, made up of employer’s National Insurance (£6,750), the minimum employer pension (about £1,310), a typical 20% recruitment fee (£10,000) and equipment (around £2,500). Training time and the ramp-up period come on top.
How much is employer’s National Insurance in 2026/27?
Employers pay 15% on each employee’s earnings above the secondary threshold of £5,000 a year. On a £50,000 salary that is £6,750. The Employment Allowance can reduce the bill by up to £10,500 a year, but growing businesses have often used it up already.
What is the minimum employer pension contribution?
Under automatic enrolment, employers must pay at least 3% of qualifying earnings, which for 2026/27 is the band between £6,240 and £50,270. On a £50,000 salary that is about £1,310 a year. Paying on full salary, or above the minimum, costs more.
How long does it take a new employee to become productive?
Typically three to six months to do the full job, with only a quarter to a half of the role covered in the first couple of months. Senior roles and sales roles usually take longer, and sales hires often need nine to twelve months to cover their own cost.
How do I calculate the payback period on a new hire?
Estimate the full first-year cost, set a realistic start date after notice, and model output month by month as the person ramps up. The payback month is when cumulative contribution (revenue they generate, or the cost of time they free up) exceeds everything spent hiring and carrying them.
