Ask a café owner what a barista costs and most will say £12.71 an hour — the National Living Wage. It's the wrong answer, and pricing your rota off it is one of the quietest ways coffee shops lose money.
The real number, once employer National Insurance, pension and holiday land, is over £15 an hour. For every hour actually worked behind the counter, it's higher still. Here's the honest build-up, and then the part that matters more: how to plan labour against revenue so the biggest cost line in your business stays under control.
The true hourly cost of a barista in 2026
Take a full-time 21-year-old barista on the National Living Wage of £12.71/hr (the rate from 1 April 2026), working 40 hours a week.
For business owners who want to take this further, the full finance guide for UK coffee shops can help you put it into practice.
Wages. £12.71 × 40 hours × 52 weeks = £26,437 a year.
Employer National Insurance. For 2026/27, employers pay 15% on earnings above the secondary threshold of £5,000 a year. So: (£26,437 − £5,000) × 15% = £3,216 a year — about £1.55 for every paid hour. Note how low that £5,000 threshold is: NI now starts almost from the first shift. UKHospitality calculated that 774,000 workers were brought into employer NIC for the first time by these changes.
Pension. Auto-enrolment requires a minimum 3% employer contribution on qualifying earnings — roughly £600 a year for this barista.
Running total: £26,437 + £3,216 + £600 = £30,253 a year, or £14.54 per paid hour. Add employer's liability insurance, uniforms, training and the odd staff meal and you're at £15+ an hour — a fifth more than the headline wage. (And no, tips can't subsidise any of this: tips never count towards minimum wage. How they're taxed — and the NI saving a proper tronc creates — is a whole subject of its own, covered in our tips and tronc guide.)

And there's one more step most owners never take. Your barista is entitled to 5.6 weeks' paid holiday, so of those 2,080 paid hours, only about 1,856 are actually worked. £30,253 ÷ 1,856 = £16.30 for every hour someone is actually behind the counter. That's the number your prices need to carry.
The direction of travel is the point as much as the level. UKHospitality put the October 2024 Budget's cost to hospitality at £3.4bn a year from April 2025, with the cost of employing a full-time staff member up by at least £2,500. Same barista, same shifts, £2,500 more per head than two years ago. If your prices haven't moved since then, your margin paid for it.
The £10,500 that softens the blow
Before you despair: the Employment Allowance knocks £10,500 a year off your employer NI bill, and most independent cafés qualify. On our numbers above, that covers the employer NI of roughly three full-time staff. It's claimed through your payroll software, not applied automatically — if you've never checked, check today. A café with four or five staff might see its true blended cost drop meaningfully once it's in.

The 18–20 rate: real arbitrage, real trade-offs
The 18–20 minimum wage is £10.85/hr, £1.86 less than the 21+ rate, and the NI and pension on top shrink proportionally. Over a 40-hour week that's roughly £75 a week, call it £3,900 a year per full-timer before on-costs (illustrative). For weekend and holiday-cover shifts, hiring younger staff is genuine arbitrage, and plenty of good cafés use it.
Be honest about the trade-offs, though. Younger staff typically need more training and more supervision, turnover tends to be higher, and a two-tier floor can grate in a small team doing identical work — some owners pay everyone the 21+ rate on principle and treat it as a retention investment. There's no universally right answer; there is a wrong one, which is building your whole staffing model on the discount and then wondering why you're permanently recruiting. (Under-18s and apprentices are £8.00/hr, with similar caveats amplified.)

Holiday pay for variable-hours staff
Casual and zero-hours staff accrue holiday too, and this is where cafés get tripped up. For staff with no fixed hours, holiday pay is based on average earnings over a 52-week reference period. The practical point: an extra roughly 12% sits on top of every casual hour you rota, whether you account for it weekly or get surprised by it in August. Build it into your hourly cost assumption from the start — it's the difference between the £15 figure being honest and being flattering.
Rota-to-revenue: the habit that keeps labour under 30%
Now the part that separates profitable cafés from busy ones. Labour typically runs at 30–35% of sales in a café (typical industry benchmark). The good operators plan it, weekly, against forecast revenue — and aim for 30% or under.
The method is simple enough to run on one sheet of paper:
- Forecast next week's sales from the same week last year, adjusted for weather, events and trend. Say £7,000 excluding VAT (illustrative).
- Set the labour budget: 30% × £7,000 = £2,100.
- Convert to hours at true cost: £2,100 ÷ £15 = 140 staff hours for the week — including you, if you're on the machine.
- Build the rota to the curve, not the clock. Those 140 hours belong where the revenue is: double-staffed for the 8–11am rush, skeleton mid-afternoon on a wet Tuesday. Flat rotas — same staffing at 3pm as 9am — are where labour percentage quietly drifts to 38%.
- Check the actual every week. Labour ÷ sales, one number, every Monday. Three weeks above 33% is not bad luck; it's a rota that needs rebuilding.
Notice what step 3 does: because it uses the true £15 cost rather than the £12.71 wage, the budget self-corrects. Owners who rota at headline wage rates think they're at 30% when they're really at 35% — and at typical café margins of 3–8%, those five points are frequently the entire profit.
Overtime vs another head
When you're stretched, overtime feels expensive and hiring feels safer. Usually it's the other way round. Occasional overtime for an existing trained barista costs you the marginal hours only. A new hire costs recruitment, training weeks at full pay and low productivity, another pension enrolment, and — the killer — the temptation to fill a rota to justify the hire. The time to add a head is when the revenue forecast sustains the extra hours at under 30%, not when a busy fortnight makes everyone tired. Run the numbers both ways first; it's a ten-minute exercise that regularly saves four figures.
The hours nobody costs: yours
One more honesty check. If you're working 40 hours a week on the machine and paying yourself little or nothing, your labour percentage is a fiction. Put your own hours into the rota at the going rate and see what the business really earns. Plenty of "profitable" cafés are actually paying their owner £4 an hour.
We saw this with a coffee shop owner in Gloucestershire — the best barista in her own business, and its prisoner, working near enough full-time behind the counter. Planning labour against revenue (with her own hours costed in, then deliberately rota'd out) was one of the changes that took her from operator to owner. The rota isn't just a cost control; it's how you buy your life back.
Staff costs are the biggest line on your P&L and the most controllable — but only weekly, in advance, against a forecast. Unlike traditional accountants who file your returns once a year and disappear, we work with you month by month, and labour percentage is on the scorecard every single week.
