You check your bank balance on a Thursday morning. There's £4,200 in the account. You think: we're doing alright.

Then rent goes out on Friday. VAT is due next week. Your flour supplier's invoice just landed. Suddenly that £4,200 looks a lot less comfortable.

This is the bank balance trap - and almost every independent café owner I know has fallen into it. Your bank balance tells you how much cash you have right now. It tells you nothing about whether your business is actually making money.

That's what a P&L does. And it's simpler than you think.

What a P&L Actually Is

A profit and loss statement - sometimes called an income statement - is just a summary of money in versus money out, over a period of time. Monthly, quarterly, or annually.

The basic structure is this:

Revenue - Costs = Profit (or Loss)

That's it. Everything else is detail about which costs go where. But that detail matters, because it tells you where your money is going - not just that it's going.

If you're using accounting software like Xero, Sage, or QuickBooks, your P&L is already being generated from your bookkeeping. If you're not sure where to find it, we've written about how these tools connect to your café operations. The point of this post is helping you actually read it.

The Four Numbers That Matter

You could spend hours analysing every line on your P&L. Or you could focus on the four numbers that determine whether your café is healthy.

1. Revenue (Turnover)

This is the total money coming in from sales, excluding VAT. Not what hits your bank account - what you actually sold. If you took £1,200 on a Saturday including VAT at 20%, your revenue for that day is £1,000.

2. Cost of Goods Sold (COGS)

This is what it costs you to make the things you sell. Ingredients, packaging, disposables - everything that goes into or around the product.

Your COGS is directly tied to your recipe costing. If you haven't costed your recipes, you're guessing this number. And guessing is expensive.

For a café, healthy COGS sits between 28% and 35% of revenue. If you're a restaurant with a bigger kitchen operation, expect 30-38%.

3. Labour Cost

This isn't just wages. It's wages plus employer National Insurance, pension contributions, holiday accrual, and any other employment costs. The true cost of an employee is typically 25-30% more than what appears on their payslip.

Healthy labour cost for a café is 25% to 35% of revenue. If you're heavily service-led (table service, kitchen brigade), you'll be at the higher end. If you're counter-service with a small team, you should be lower.

4. Overheads

Everything else. Rent, business rates, utilities, insurance, equipment maintenance, marketing, accountancy fees, subscriptions, repairs, cleaning supplies - the list goes on.

Healthy overheads for a café sit between 20% and 30% of revenue. Rent alone is often 8-12% in the UK, and in high street locations it can be more.

Gross Profit vs Net Profit

These two get mixed up constantly - and the difference is important.

Gross profit is your revenue minus COGS. It tells you how much money you have left after paying for the things you sell, before you pay for anything else.

Revenue £350,000 - COGS £108,500 = Gross Profit £241,500 (69%)

Net profit is what's left after everything - COGS, labour, overheads, depreciation, interest, the lot. This is your actual profit.

Gross Profit £241,500 - Labour £98,000 - Overheads £84,000 = Net Profit £59,500 (17%)

Gross profit tells you whether your pricing and recipes work. Net profit tells you whether your business works.

What "Good" Looks Like

Here are realistic benchmarks for a well-run independent café in the UK. These aren't aspirational - they're achievable with proper costing and cost control.

Line Item	% of Revenue	On £350K Turnover
Revenue	100%	£350,000
COGS (food + packaging)	28-35%	£98,000 - £122,500
Gross Profit	65-72%	£227,500 - £252,000
Labour	25-35%	£87,500 - £122,500
Overheads	20-30%	£70,000 - £105,000
Net Profit	5-15%	£17,500 - £52,500

Net profit of 5-15% is typical for a well-run indie. If you're consistently above 10%, you're doing well. If you're below 5%, something needs attention - and the P&L will tell you what.

Restaurants tend to run tighter. Higher food costs (30-38%), heavier labour requirements, and the margins get squeezed from both sides. A restaurant doing 8% net profit is performing well.

A Worked Example: The Fictitious Flat White Café

Let's say you run a café doing £350,000 turnover (ex-VAT). Here's what a healthy monthly P&L might look like.

	Monthly	Annual	%
Revenue	£29,167	£350,000	100%
COGS	£9,042	£108,500	31%
Gross Profit	£20,125	£241,500	69%
Wages + NI + pension + holiday	£8,167	£98,000	28%
Rent	£2,500	£30,000	8.6%
Business rates	£500	£6,000	1.7%
Utilities	£917	£11,000	3.1%
Insurance	£250	£3,000	0.9%
Repairs + maintenance	£333	£4,000	1.1%
Marketing + subscriptions	£250	£3,000	0.9%
Accountancy + legal	£208	£2,500	0.7%
Depreciation	£417	£5,000	1.4%
Sundries + other	£333	£4,000	1.1%
Total Overheads	£5,708	£68,500	19.6%
Net Profit	£6,250	£75,000	21.4%

That 21.4% net profit looks excellent. But here's the catch - if the owner hasn't paid themselves a salary and they're showing up six days a week, that £75,000 isn't profit. It's their wage. Which brings us to the most common mistake.

Common P&L Mistakes Indie Operators Make

Not including owner's wages

If you work in the business, your time has a cost. If you'd have to pay someone £35,000 a year to do your job, your P&L should reflect that. Otherwise your "profit" is just unpaid wages.

In our worked example, once you deduct a £35,000 owner's salary, net profit drops from £75,000 to £40,000 - still healthy, but a very different picture.

Ignoring depreciation

That £12,000 oven doesn't last forever. If it lasts ten years, you're using up £1,200 of value each year. Your P&L should capture this as depreciation - otherwise you'll be caught short when the equipment needs replacing.

Mixing personal and business expenses

Your car, your phone, your home broadband. If they're running through the business but they're partially personal, your costs are overstated and your profit is understated. Keep them clean.

Looking at it once a year

A P&L is most useful when you look at it regularly - monthly at minimum. Quarterly reviews are fine for trend-spotting, but monthly lets you catch problems before they compound.

Seasonal Patterns in Your P&L

Café P&Ls aren't flat. They follow patterns, and understanding those patterns stops you panicking in the quiet months.

January and February are typically the quietest. Lower revenue, but your fixed costs (rent, rates, insurance) stay the same. Expect tighter margins.
Summer months bring higher footfall but potentially higher labour costs if you're staffing up for the season.
December can be strong for retail and gift sales, but often dips after Christmas.
Easter and bank holidays can swing either way depending on your location.

The mistake is comparing January to July and worrying. Compare January 2026 to January 2025. That tells you whether you're improving, not whether January is quieter than summer - because of course it is.

How Recipe Costing Feeds Into the P&L

Your COGS line on the P&L is only as accurate as your recipe costing. If you haven't costed your recipes, or you costed them two years ago and haven't updated since, your P&L is telling you a story that may not be true.

Here's the connection: every ingredient price change flows through to your COGS. When your butter goes up 15%, every recipe that uses butter costs more. When your coffee supplier switches origin, your flat white margin shifts. With the volume of cost increases hitting cafés right now, staying on top of this matters more than ever.

If you're updating recipes manually in a spreadsheet, you're always behind. By the time you've recalculated everything, prices have moved again.

Making It Practical

You don't need an accounting degree to read your P&L. You need four numbers, a monthly habit, and the willingness to look at what the numbers are telling you - even when it's uncomfortable.

Here's a simple checklist:

COGS under 35%? Your pricing and recipes are working.
Labour under 35%? Your team structure is sustainable.
Overheads under 30%? Your fixed costs are controlled.
Net profit above 5%? The business is viable. Above 10%? You're running a tight ship.

If any of these are out of range, you know where to look. That's the power of a P&L - it turns "we feel busy but we're not making money" into "our labour cost is 38% and here's why."

When You Want the Numbers to Update Themselves

Reading your P&L monthly is the right habit. But pulling the numbers together manually - reconciling invoices, tracking ingredient costs, calculating labour percentages - takes time most operators don't have.

That's what PulseBrik does. It pulls your revenue, COGS, labour, and overheads together automatically and surfaces the numbers that matter - in real time, not six weeks after the month ends when your accountant sends the management accounts. It connects the recipe costing from CostingBrik and the labour costs from StaffBrik, so your P&L picture is always current.

No spreadsheets. No waiting for your accountant. Just the four numbers that tell you whether your café is making money.
