Where a restaurant's money actually goes

The gap between busy and profitable

A restaurant can be full every Friday and still lose money. This is not unusual and it is not a mystery — it is arithmetic, and the arithmetic fits on one sheet of paper.

Most owners can tell you their daily sales to the rupee. Far fewer can tell you what percentage of those sales they keep. That second number is the one that decides whether you are building something or funding a hobby with good reviews.

This guide covers what a realistic margin looks like in India, how to work yours out from figures you already have, and which of the four levers is worth pulling first.

What a realistic margin looks like

Net margin is what remains after everything — food, staff, rent, utilities, licences, maintenance, marketing, software, your accountant, and your own salary.

Two warnings about these ranges.

First, if your calculated margin is above 20%, check what you left out before you celebrate. The usual omissions are your own salary and the depreciation on your fit-out. A ₹40 lakh interior does not last forever, and pretending it costs nothing per month makes every year look better than it was.

Second, if you are at 3% or below, you are one bad quarter — a monsoon, a road closure, a kitchen breakdown — from real trouble. That is a signal to act now while you still have options, not a number to average out over the year.

The four costs, in the order they matter

1. Food and beverage cost

Usually 28–35% of sales for a dine-in restaurant in India. It is the cost owners watch most and understand least, because the number on the recipe sheet and the number your kitchen actually produced are rarely the same.

The full method, with a worked example, is in how to calculate food cost percentage. The short version: use opening stock plus purchases minus closing stock, divided by sales — not your theoretical recipe cost. The gap between the two is your waste, over-portioning and pilferage, and it is where the money is.

2. Labour cost

Usually 20–30% of sales, including your own salary whether or not you draw it.

That last clause matters. An owner working sixty hours a week and not paying themselves is subsidising the business with unpaid labour, and every margin calculation that ignores it is fiction. Put a real replacement salary in the sheet. If the restaurant still works with that number in it, you have a business. If it only works because you are free, you have a job.

3. Prime cost — the one number to watch weekly

Prime cost = food cost + labour cost, as a percentage of sales.

This is the number to put on the wall. Food and labour trade off against each other — a kitchen that preps more in-house cuts food cost and raises labour; buying more prepared inputs does the reverse. Watching one in isolation lets you improve it while the total gets worse.

Check it weekly, not monthly. Monthly tells you what happened; weekly tells you in time to change something.

4. Rent and fixed overheads

Rent should sit under 10% of revenue. Ideally 6–8%.

This is the cost you cannot fix later. Every other lever on this page can be pulled next week. Rent is set the day you sign the lease and caps your margin for the length of it. A restaurant paying 15% of revenue in rent has to run everything else near-perfectly to reach an ordinary margin — and it has no room at all in a slow quarter.

If you are past this decision, the only remaining lever is revenue: rent as a percentage falls as sales rise. That is one of the few genuine arguments for pushing volume even at the cost of some margin per cover.

A worked example

A 28-seat casual dining restaurant, one month:

This restaurant is in good shape. Prime cost at 58% is healthy, rent under 9% leaves room, and 15.7% net is at the top of the realistic band.

Now change one thing. Suppose food cost drifts to 36% — a slow, invisible drift from over-portioning and a supplier price rise nobody renegotiated:

• Food cost becomes ₹3,45,600, up ₹38,400
• Net profit falls to ₹1,13,000, a margin of 11.8%

A four-point move in one cost line took a quarter of the profit. Nothing visible changed in the restaurant. The room looked identical.

Now the other direction. Raise prices 5% with no change in covers:

• Sales become ₹10,08,000
• Food cost stays ₹3,07,000 in rupees, falling to 30.5% of sales
• Net profit becomes ₹1,99,400 — a margin of 19.8%

Nearly the entire price rise landed in profit. This is why price is the first lever, not the last.

Common mistakes

Not paying yourself. Covered above, and the most common error by a distance. It makes a marginal restaurant look healthy for years.

Confusing gross margin with net margin. "We make 70% on food" is a gross margin on one dish. It says nothing about whether the business is profitable after rent and staff.

Discounting to fill quiet nights. A 20% discount on a dish with a 68% gross margin does not cost you 20% — it costs you nearly a third of the contribution from that cover. Filling Tuesday at a discount can lower your monthly profit while raising your covers. If the goal is to fill quiet nights, getting existing guests to return is almost always cheaper than discounting to strangers.

Cutting the wrong costs. Trimming staff during service to save labour cost slows table turnover, which cuts covers, which cuts sales — and labour as a percentage often goes up. Cut cost from waste, portioning and supplier terms, not from the people making the covers happen.

Reviewing annually. By the time a year's accounts arrive, the drift has been running for eleven months. Monthly on one sheet beats annually in detail.

What to do this week

1. Build the sheet. One row per cost line, one column per month. Sales, food, labour, prime cost, rent, utilities, other, net. It does not need to be sophisticated to be useful.

2. Put a real salary in the labour line — yours, at replacement cost, whether or not you take it.

3. Calculate prime cost. If it is above 65%, stop reading and work on that. Nothing else on this page matters until it comes down.

4. Check your rent percentage. Above 10%, your growth plan has to be revenue-led, because the cost side cannot save you.

5. Find your three least price-sensitive dishes and raise them 5–8%. Signature items guests come specifically for, not the recognisable value dishes they use to judge whether you are expensive.

6. Set a monthly date and keep it. The discipline of looking beats the sophistication of the tool.

If you want a broader dashboard once the margin sheet is running, the twelve numbers worth checking every week covers what to add next and what to leave out.

The short version

• A healthy Indian independent restaurant nets 8–15% after everything, including a real salary for you.
• Prime cost — food plus labour — is the one number to watch weekly. Above 65% of sales, most independents stop working.
• Rent above 10% of revenue caps your margin structurally and cannot be fixed after the lease is signed.
• A 5% price rise on the right dishes beats a 5% cost cut, lands immediately, and carries no execution risk.
• Discounting costs far more contribution than the headline percentage suggests. Repeat visits are cheaper than discounts.
• Monthly, on one sheet, with your own salary in it. That habit is worth more than any software.
