5 Financial Reports Every UK Restaurant Owner Should Review Monthly

You know what most independent café owners use as their financial dashboard? Their banking app.
If there's enough in the account to cover payroll, they exhale. If there isn't, they panic. And everything in between is guesswork.
With the National Minimum Wage now at £12.71, employer NI at 15%, day-one SSP obligations, and food inflation still biting, guesswork isn't good enough any more. The operators who survive - and actually thrive - are the ones who sit down once a month with five reports and ask: what are my numbers really telling me?
This isn't about becoming an accountant. It's about building a simple review habit that takes two hours a month and saves you from nasty surprises. Here are the five reports that matter.
1. Profit & Loss Statement - The Big Picture
Your P&L is the single most important report in your business. It answers one question: are you actually making money, or just turning over cash?
We've written a full guide to reading your café P&L if you want the deep dive. But for your monthly review, focus on three things.
What to look at
- Net profit percentage. This is your bottom line after everything - COGS, labour, rent, rates, utilities, the lot. For a healthy independent café, you're aiming for 5-15%. Below 5% and you're working for free. Above 15% and you're running a very tight ship.
- Month-on-month trends. One bad month isn't a crisis. Three in a row is a pattern. Plot your net profit percentage across the last six months and look at the direction.
- Seasonal patterns. Compare this month to the same month last year, not last month. January will always look worse than December. That's not a problem - that's weather.
What "good" looks like
| Metric | Healthy range |
|---|---|
| Net profit margin | 5-15% |
| Gross profit margin | 65-72% |
| COGS as % of revenue | 28-35% |
If your gross profit margins are within range but your net profit is weak, the problem isn't your recipes - it's your overheads or labour. The P&L tells you where to dig.
Red flags
- Net profit below 3% for two consecutive months
- Gross margin dropping while revenue holds steady (costs are creeping)
- Revenue growing but profit shrinking (you're selling more but making less per sale)
How often
Monthly minimum. Weekly if you have real-time data from your POS and accounting software.
2. Food Cost Report - Are Your Ingredient Costs Creeping?
Your food cost is the cost you have the most direct control over. But it's also the one that drifts fastest, because supplier prices move constantly and most operators don't notice until the quarterly accounts land.
If you haven't got a handle on how to track this number, our guide on how to calculate food cost percentage covers the basics.
What to look at
- Theoretical vs actual food cost. Your theoretical food cost is what your recipes say it should cost, based on current ingredient prices. Your actual food cost is what you really spent, divided by what you really sold. The gap between these two numbers is where your money disappears - through waste, over-portioning, theft, or unrecorded stock.
- Variance analysis. If your theoretical food cost is 29% but your actual is 34%, that 5% gap on a £25,000 weekly turnover is £1,250 a week walking out the door.
- Supplier price drift. Your butter was £2.80/kg in January. Now it's £3.15/kg. Did you notice? Did you adjust your menu prices? Recipe costing that tracks supplier prices catches this automatically.
What "good" looks like
| Metric | Healthy range |
|---|---|
| Food cost percentage | 28-35% |
| Theoretical vs actual gap | Under 2% |
| Supplier price variance | Flagged within 7 days |
Red flags
- Actual food cost more than 3% above theoretical (waste or portioning problem)
- A single supplier's prices increasing more than 5% without discussion
- Food cost rising while menu prices stay flat
How often
Monthly deep dive, with weekly spot-checks on actual vs theoretical if you have the data. Flag any supplier price increase over 3% immediately.
3. Labour Cost Report - Your Biggest Controllable Cost
Labour is almost certainly your largest single cost line, and after the April 2026 NMW and NI changes, it just got more expensive for every hospitality business in the country.
The mistake most operators make is looking at payroll in isolation. Your wages bill tells you what you paid people. It doesn't tell you whether that spend was efficient, or whether you're overstaffed on Tuesdays and understaffed on Saturdays.
What to look at
- Labour as a percentage of turnover. Total employment cost (not just wages - include employer NI at 15%, pension, holiday accrual, SSP provision) divided by revenue. For a café, target 25-35%. For a full-service restaurant with a kitchen brigade, expect 30-38%.
- Cost per cover. Total labour cost divided by the number of customers served. This normalises for volume and tells you whether your staffing scales sensibly with demand.
- Overtime tracking. Overtime is expensive - often 1.5x or more. If your rota regularly generates overtime, the rota needs fixing, not the team.
- The true cost post-NI/NMW increases. A staff member on £12.71/hour doesn't cost you £12.71. With employer NI, pension, and holiday accrual, the true cost is closer to £15.80-£16.20/hour. If you're not calculating this, your labour percentage is understated.
What "good" looks like
| Metric | Healthy range |
|---|---|
| Labour as % of turnover | 25-35% |
| Cost per cover | £3.50-£6.00 (café), £6.00-£10.00 (restaurant) |
| Overtime as % of total hours | Under 5% |
If your labour cost is running high, building a rota that controls labour costs is the first lever to pull - before you start cutting shifts and burning out your team.
Red flags
- Labour above 38% of turnover for two consecutive months
- Cost per cover increasing while average transaction value stays flat
- Regular overtime in the same roles (indicates a headcount or scheduling problem)
- Agency or temporary staff costs exceeding 5% of total labour
How often
Monthly review of the full picture. Weekly rota-vs-actual comparison if your system supports it. StaffBrik shows true employment cost per team member, so you can see the real number, not just the payslip figure.
4. Sales Mix Analysis - What's Actually Making You Money
You know your best seller. But do you know your most profitable item? They're rarely the same thing.
A flat white might be your top seller at 240 a week. But if your smoked salmon bagel sells 30 a week at a £4.20 contribution margin, those 30 bagels are contributing almost as much profit as 240 flat whites at £0.55 margin each.
This is where your POS data meets your recipe costing - and where the real insights live.
What to look at
- Stars vs dogs. In menu engineering terms, a "star" is high popularity and high margin. A "dog" is low popularity and low margin. You want more stars, fewer dogs, and a clear plan for everything in between.
- Contribution margin by item. Not just the percentage - the actual pounds and pence each item contributes after ingredient cost. A 60% margin on a £2.80 Americano is £1.68. A 55% margin on a £9.50 brunch plate is £5.23. The brunch plate wins.
- Category performance. How are your drinks doing vs food? Hot food vs cold? Retail vs eat-in? Looking at this by category shows you where growth or decline is happening.
What "good" looks like
| Metric | What to target |
|---|---|
| Top 20% of items | Should contribute 60%+ of total gross profit |
| Menu dogs | No more than 10-15% of your menu |
| Category GP margin | Drinks: 72-80%. Food: 60-70%. Retail: 45-55% |

Red flags
- Your best seller has one of your lowest margins
- More than 20% of your menu items are "dogs" (low popularity, low margin)
- A category's gross profit is declining while its revenue holds (prices haven't kept pace with costs)
- Promotional items cannibalising higher-margin alternatives
How often
Monthly deep dive. Review whenever you change the menu or adjust prices. If you're using POS data, a weekly glance at your top and bottom performers takes five minutes and often reveals surprises.
5. Cash Flow Forecast - The Report Most Operators Skip
Here's a fact that surprises people: profitable businesses go bust. It happens more often than you'd think, and it almost always comes down to cash flow.
Your P&L might show a £4,000 net profit for March. But if you have £8,000 of supplier invoices due next week, a quarterly VAT bill landing, and a staff member owed holiday pay, you can be profitable on paper and overdrawn in reality.
Cash flow and profit are different things. Your P&L records income and expenses when they happen. Cash flow tracks when the money actually moves.
What to look at
- The 13-week rolling forecast. Project your expected cash inflows and outflows for the next 13 weeks. Include everything - revenue (be conservative), payroll, supplier payments, rent, rates, VAT, PAYE, loan repayments, equipment purchases. Update it weekly and roll it forward.
- Seasonal planning. If you know January is quiet, start planning in November. If summer brings higher revenue but also higher casual staffing costs, model that. The forecast removes the surprise.
- Minimum cash buffer. How many weeks of fixed costs can you cover if revenue dropped 30% tomorrow? Two weeks' cover is uncomfortable. Four weeks is sensible. Eight weeks is solid.
What "good" looks like
| Metric | Target |
|---|---|
| Cash buffer | 4-8 weeks of fixed costs |
| Forecast accuracy | Within 10% of actual, consistently |
| VAT/PAYE provision | Set aside monthly, not scrambled quarterly |
Red flags
- Cash balance trending down over three consecutive months
- Regularly dipping into overdraft in the same weeks each month (a timing problem you can fix)
- No provision set aside for VAT or PAYE (these aren't optional and HMRC doesn't wait)
- Delaying supplier payments to cover payroll
How often
Update your 13-week forecast weekly. It takes 15 minutes once the template is set up. Review the full cash position monthly alongside your P&L.
Building the Monthly Review Habit
Five reports sound like a lot. But once you have the data flowing, a monthly review takes about two hours.
Here's a simple system that works.
Block the first Monday of every month. Put it in your calendar. Protect it. This is a non-negotiable meeting with your business.
The two-hour agenda:
- P&L review (30 minutes) - Net profit %, month-on-month comparison, same-month-last-year comparison. Are you on track?
- Food cost deep dive (20 minutes) - Theoretical vs actual. Top 10 ingredients by spend. Any supplier price jumps?
- Labour check (20 minutes) - Labour as % of turnover. Cost per cover. Any overtime patterns?
- Sales mix scan (20 minutes) - Stars and dogs. Category performance. Any items that need repricing?
- Cash flow update (30 minutes) - Roll the 13-week forecast forward. Check your buffer. Any lumpy payments coming up?
You don't need all five reports to be perfect from day one. Start with the P&L and food cost report. Add labour and sales mix in month two. Bring in the cash flow forecast by month three. Within a quarter, you'll have a complete picture of your business, and you'll wonder how you ever managed without it.
When You Want All Five in One Place
The monthly review works with spreadsheets. Plenty of great operators have run their businesses this way for years.
But pulling the numbers together manually - reconciling invoices, calculating actual food cost, working out true labour cost with NI and pension, running sales mix from your POS - takes time. Time that most café owners spend behind the counter, not behind a desk.
That's what PulseBrik is designed for. It pulls your P&L, food cost, labour, and sales performance into a single dashboard - updated in real time from your CostingBrik recipes, StaffBrik rotas, and POS data. The five reports in this post, in one place, without the spreadsheet gymnastics.
Your numbers are already there. PulseBrik just makes them visible - so your first Monday review takes 30 minutes instead of a full morning.
