How much money should a restaurant make?

You are busy. The room fills, the tickets print, the deposits land every morning. And at the end of the month there is nothing left. You typed the question because you wanted a number to hold yourself against — and every page the search returned gave you the same one.

The number in circulation

Three to five per cent. Some pages say six; one allows a range from nothing to fifteen. None of them says where the number comes from, and it does not matter, because the number is real. It is what the trade makes on average, and the average is restaurants flying without instruments: a menu priced by feel, a schedule built from habit, a P&L read once a year by an accountant who has never stood on the line. Three to five per cent is the margin of not measuring.

This firm does not work to that number, and it does not ask you to take that on faith. Two operations are on this site with a first full trading year in the open, and both sit above the top of the published range. One is a full-service room whose ledger is engineered line by line to a net operating income of 17.33%. The other is a fast-casual kitchen whose first year is measured from the partners' own books: $250,077 before financing, 16.2% of sales. The rest of this note walks that second record, all of it — the good year and the ugly half-year that followed — because the folklore has one number and a real restaurant has several.

What "make" means

"How much does a restaurant make" is three questions wearing one sentence, and a monthly statement answers each of them on a different line.

The first is operating earnings: sales less everything it costs to trade — food, beverage, fully burdened payroll, rent, fees, utilities, repairs — before financing, tax, depreciation and anything the owners take out. It is the number that says whether the machine works. In its first full year the fast-casual unit's operating cost ran 83.8% of sales, and 16.2% was left.

The second is financing: what the debt takes before anyone else does. In that first year it took $5,050.

The third is what the owners took: $245,027. That is the number you meant when you typed the question. It is the third line, not the first, and nothing on the first two lines tells you what it will be.

Basis, so the comparison is honest: cash basis, before tax and depreciation, from the partners' monthly workbook, not audited, and tying to the point of sale plus the wholesale invoices month by month. The survey figures on the other pages are net profit as their respondents defined it, after everything. Set the two side by side with that said, or not at all.

The ugly half

Then the second year began, and the same three lines tell a different story. Like for like, the first half of 2026 against the first half of 2025: sales up 8.6%, operating cost from 81.5% to 87.4%, the operating margin from 18.5% to 12.6%. Financing took $103,981. The partners took $961 — on $835,879 of sales. That last figure is not a misprint.

Two separate things happened.

The financing line is the partners' choice. The loan funds their next location and is repaid from this unit's card receipts, so the unit's whole first half of earnings went out of the door to open the next one. It is a below-the-line decision and it means exactly what it says: a forty-hour-a-week campus kitchen carried a second opening on its own cash. Nobody was surprised by the number. It was the plan.

The operating line is the trade, and that one bites. Food and beverage went from 28.8% of sales to 31.8%; the other operating lines from 15.3% to 18.0%, about half of it the rent that began in the second year. Under an agreement that fixes list prices about a fifth below the sister property's and does not let the operator lift them without consent, every point that ingredients rose came straight out of the margin. The fix is in flight — a 10% increase, timed to the landlord's budget cycle — and until it lands the margin is what it is, and the case study says so.

That is what "make" looks like from inside. It is three lines, a good year, a hard half, a cause on each line, and a decision against each cause. The folklore cannot show you that, because the folklore is an average of restaurants that never looked.

Where the number comes from

A margin above the published range takes three pieces of work, done in this order, and the record shows each one.

A concept, written all the way through. Before the kitchen was drawn, the unit had a projection on paper — $1,069,590 of first-year retail sales — and a price ceiling, a footprint and a service model to reach it with. The first full year came in 19.5% above it. A concept that is written down can be wrong in a measurable direction. One that lives in the owner's head can only be defended.

Implementation that does not drift. The concept said two minutes from order to hand-over. Across 74,755 tickets the kitchen display measured a median of 1 min 54 s, with 96% inside six minutes — and the line ran faster under load, not slower.

Adjusting while operating. The ugly half above. Cost moved, the books showed it the month it moved, and the operator is acting on the one line he can act on. An operation that cannot see its cost move until the year-end statement has no adjustment to make — only a loss to explain.

The thirty per cent rule

You will also have met the rule of thumb: thirty for food, thirty for labour, thirty for everything else, ten left over. It is a budget for an operation nobody has measured. This firm underwrites against one line instead — total operating cost never above 80% of sales — and lets the blocks fall where the concept puts them. In the fast-casual unit's first year the blocks were food and beverage 29.1%, payroll 38.5% with every tax inside it, everything else 16.2%: 83.8% all in, above the ceiling, and the case study says why. The full-service ledger holds prime cost — goods plus fully burdened labour — at 64.48%. Neither is thirty-thirty-thirty.

What a turnaround depends on

Nobody can tell you what your restaurant will make after it is fixed — not a search result, and not this firm. An audit produces an analysis and a recommendation. What happens next is yours: the findings have to be implemented quickly and completely, and then held, month after month, without drifting back to what the room was doing before. Nothing guarantees that anyone follows a recommendation. We have watched good ones die on a whiteboard.

What we can say is when it tends to work. Four conditions, in our experience, and they are about the owner more than the kitchen: an open mind; the means to carry the change through the months it takes to show; a customer base that will support the operation the numbers say you should be running; and an owner who is not married to anything already in the building — a dish, a price, a person, a habit. With those four in place there is a good chance of success. Without them, the distance between three per cent and sixteen is a number on someone else's website.

And it takes time. A margin is not found in a week.

The audit is where it starts: five days, a fixed fee, and four documents — the menu, the P&L, the point-of-sale export and the floor plan. The form on the front page asks for exactly those. If you are running a room that is full and a month that ends empty, that is the whole brief.
