A year ago, most cafe owners were still trying to work out what the employer NI changes would actually mean for their wage bill. The rate going from 13.8% to 15% was one thing. The secondary threshold dropping from £9,100 to £5,000 was another. But very few people had done the maths on both at the same time.

Now we have twelve months of payroll data. The numbers are in. And for most hospitality businesses, the hit was worse than the headlines suggested.

The Headline Number

For a full-time employee on the National Minimum Wage, employer NI jumped roughly 60% year-on-year.

Before April 2025, you paid around £1,617 per year in employer NI on a full-time NMW worker. After the changes, that same employee costs you £2,583 per year in NI alone. That's an extra £966 - per person, per year - that didn't buy you a single extra hour of work.

Two things drove that increase:

The rate increase: 13.8% to 15% (a 1.2 percentage point jump)
The threshold drop: from £9,100 to £5,000 per year (meaning NI kicks in £4,100 earlier for every employee)

The threshold change was the bigger factor. It dragged part-time workers who were barely over the old threshold firmly into NI territory, and added cost to every employee above it.

What It Actually Cost a Typical Cafe

Let's look at two real-world scenarios. These are based on standard hospitality team structures - not edge cases.

Scenario 1: Small cafe, 5 staff

Three full-time employees on NMW (40 hrs/week) and two part-time (16 hrs/week).

	Before April 2025	After April 2025	Increase
3 x full-time NI	£4,851	£7,749	+£2,898
2 x part-time NI	£882	£1,796	+£914
Total employer NI	£5,733	£9,545	+£3,812

That's an extra £3,812 per year - or roughly £317 a month - just in NI. No new hires. No pay rises. Same team, same hours, same output.

Scenario 2: Busier operation, 10 staff

Five full-time, five part-time. Same rates.

	Before April 2025	After April 2025	Increase
5 x full-time NI	£8,085	£12,915	+£4,830
5 x part-time NI	£2,205	£4,490	+£2,285
Total employer NI	£10,290	£17,405	+£7,115

That's over £7,100 a year in extra NI. To put it in cafe terms: at a 70% gross margin on a flat white, you'd need to sell an extra 27 flat whites every single day just to cover the NI increase. Every day. For the entire year.

The Compounding Problem

The NI rise didn't happen in isolation. It landed alongside NMW increases in both April 2025 and April 2026, SSP reforms, and the end of business rates relief. Each one feeds into the others.

Here's why that matters: every time the NMW goes up, your employer NI goes up too - because you're paying 15% on a larger base. And because the threshold is frozen at £5,000 until at least April 2028, each future wage increase hits harder than it would have under the old threshold.

This compounding effect is what caught so many operators off guard. It wasn't one big cost increase. It was three or four increases, each one amplifying the others. We mapped the full picture in The April 2026 Cost Cliff - and the NI piece is the thread running through all of it.

How Operators Adapted

Over the past year, we've spoken to dozens of cafe and bakery owners about how they responded. The strategies fell into a handful of categories.

Reduced hours, not headcount

The most common move. Rather than letting someone go, operators trimmed hours across the team - cutting a shift here, shortening an overlap there. This reduces NI liability (fewer earnings above the threshold) but puts pressure on service levels and staff morale.

Restructured rotas around the threshold

Some operators restructured shifts so that more employees sat just below the £5,000 annual earnings threshold - effectively creating micro-roles to avoid triggering NI. It works on paper, but it's fragile. One extra shift and you're back over the line. If you're managing your rota and labour costs this tightly, you need real-time visibility into what each hour actually costs you.

Absorbed the cost

Plenty of operators simply absorbed it - eating into already thin margins. For some, that meant the difference between a profitable month and a loss-making one. This was especially common in businesses where prices were already at the ceiling of what customers would accept.

Passed it to customers

Some raised prices. A 10-15p increase on a cup of coffee doesn't sound like much, but it adds up - and in a market where customers are already stretched, every increase carries a risk. The operators who did this well tied it to visible quality improvements, not just cost absorption.

Invested in efficiency

A smaller group used the NI rise as a trigger to seriously look at their operations. Tighter scheduling. Better forecasting. Automating the admin that was eating into productive time. This is the group that came out ahead.

How to Calculate Your True NI Cost Per Employee

If you want to know exactly what you're paying, here's the formula for 2025/26 and 2026/27:

Employer NI = (Annual earnings - £5,000) x 15%

For a full-time NMW employee from April 2026 (£12.71/hr, 40 hrs/week):

Annual earnings: £26,437
Minus threshold: £26,437 - £5,000 = £21,437
Employer NI: £21,437 x 15% = £3,216 per year

For a part-time employee (16 hrs/week):

Annual earnings: £10,575
Minus threshold: £10,575 - £5,000 = £5,575
Employer NI: £5,575 x 15% = £836 per year

But NI is only one piece. You also need to factor in:

Employer pension (3% on qualifying earnings above £6,240)
Holiday accrual (12.07% of base pay for statutory entitlement)
SSP liability (now from day one - see the SSP changes breakdown)

The true cost of employment for a full-time NMW worker is now over £33,400 per year. That's the number you should be measuring against - not the hourly rate on the job advert.

What to Plan for in 2026/27

The NI rate and threshold aren't changing this April - the 15% rate and £5,000 threshold carry forward. But that doesn't mean your NI bill stays flat.

Here's what's moving:

NMW to £12.71/hr means higher earnings, which means more NI on each employee
The threshold freeze continues until at least April 2028 - so each wage rise pushes more of your payroll above the line
Business rates relief is gone, meaning many operators have less headroom to absorb employment costs
SSP from day one adds a new cost layer that sits alongside NI

If you haven't recalculated your labour costs since the original April 2025 changes, now is the time. The numbers have shifted again.

Three things to do this month

Recalculate the true cost of every employee. Not just wages - include NI, pension, holiday, and SSP. If you're still using a spreadsheet from last year, the numbers are wrong.
Model your scenarios. What happens if the NMW goes up again next April? What if you hire one more person? What if you cut Friday afternoon shifts? Run the numbers before you make the decision, not after.
Track it automatically. The problem with manual calculations is they go stale the moment something changes. StaffBrik tracks the true cost of every employee in real time - NI category, pension status, holiday accrual, the lot. When the rules change, your numbers update. When you add someone to the rota, their full cost appears alongside everyone else.

The Bigger Picture

The employer NI rise was sold as a one-off fiscal adjustment. A year on, it's clear that it's a structural shift in the cost of employing people in the UK. The rate is higher, the threshold is lower, and both are frozen in place while wages keep climbing.

For hospitality - where labour is typically 30-35% of turnover and margins are already thin - this isn't something you can just absorb and forget about. It needs to be a number you know, track, and plan around. Every rota you build, every hire you make, every price you set should factor in the true cost of the people delivering the work.

The operators who are navigating this well aren't the ones who found a clever trick to dodge NI. They're the ones who know their numbers - properly, in real time - and make decisions based on what things actually cost, not what the payslip says.

That's the difference between surviving April and planning for the next twelve months.
