How to Read a Restaurant P&L Without an Accounting Background

Most operators receive their monthly accounts, look at the bottom line, feel either relieved or worried, and file them. The document is treated as a report card rather than a tool, which is a waste, because a properly built profit and loss statement will tell you what to do next week.

You do not need an accounting qualification to read one usefully. You need to know which four or five lines actually move, and what they should look like for a business like yours.

Start with prime cost, not with profit

Add your cost of goods sold to your total labour cost, including CPF and any levies. Divide that by your revenue. That percentage is your prime cost, and it is the most useful single number in the document.

It matters because it is the part you can influence. Rent is contracted. Depreciation is a schedule. Prime cost changes with what you put on the menu, how you buy, how you portion, and how you roster. If prime cost is drifting upward month on month, nothing further down the page will save you.

Look at it as a trend across twelve months rather than as a single figure. One bad month can be a stocktake timing issue. Six months of gradual movement in the same direction is a structural problem.

Read the percentages against covers, not against last year

Comparing this June to last June is comforting and often misleading. Volumes change, the menu changes, prices change, and public holidays fall differently.

A more useful comparison is per cover. What did you take per cover, and what did it cost you to serve that cover in food and in labour? When revenue rises but profit does not, the per cover view usually shows why: either the average spend fell while volume rose, or the labour hours grew faster than the covers did.

Know what is hiding in your cost of goods

Cost of goods sold is a single line, and it conceals several different things: what you bought, what you wasted, what you gave away, what walked out of the door, and how accurately you counted stock at each month end.

If your food cost percentage jumps in one month and returns to normal the next, the most likely explanation is a stocktake error rather than a sudden change in buying. If it climbs steadily and stays there, something real has changed: supplier prices, portion discipline, menu mix, or the volume of items being remade and thrown away.

This is why the P&L is only half the picture. It tells you that something moved. Finding out what moved usually requires standing in the kitchen.

Watch other operating expenses

The line that quietly grows in most food and beverage businesses is the one nobody owns. Delivery platform commissions, payment processing fees, software subscriptions, repairs, pest control, laundry, packaging, and marketing all sit there, individually small and collectively significant.

Once a year, print that section and go through it line by line. Operators routinely find subscriptions for systems they stopped using and service contracts that were never renegotiated after the first term.

One page, every month

The most useful reporting pack in food and beverage is short. One page, produced within a week of month end, showing revenue, covers, average spend, food cost percentage, labour percentage, prime cost, occupancy cost, and the resulting operating profit, each against the previous month and against the same period last year.

If your monthly reporting takes a fortnight to produce and runs to fifteen pages, it is a compliance exercise, not a management tool. By the time you read it, the month it describes is too far behind you to act on.

Salt and Ledger builds reporting that operators and their banks can both read. That means an operating model with sensitivities, a one page monthly pack that reduces month end to something you can review over a coffee, and a handover so your own team can maintain it once we step back.
