Restaurant profit margins explained

Gross margin, net margin, prime cost: the three profit metrics every restaurant owner needs to understand and the relationship between them.

Restaurant profitability is measured at several layers. Knowing which metric you are looking at — and what it does and does not include — prevents you from drawing the wrong conclusions about your business.

Gross profit margin

Gross profit margin = (selling price minus food cost) divided by selling price x 100

This is the simplest measure of per-dish profitability. It tells you how much of each sale remains after raw ingredient and packaging cost. A 70% gross margin on a $10 dish means $7 remains to cover labor, rent, utilities, and everything else.

Industry averages for gross margin in US restaurants: 60 to 75%. Fine dining and premium concepts often run higher (75 to 80%) because higher prices outpace ingredient costs. High-volume quick service tends to run 65 to 72%.

Prime cost

Prime cost = food cost + beverage cost + labor cost (wages, benefits, payroll taxes)

Prime cost is the most widely tracked operational metric in foodservice because food and labor together represent 55 to 65% of most restaurant's total revenue. If prime cost is under control, the business is usually profitable. If prime cost is high, everything else is harder.

Target prime cost benchmarks:

Full-service restaurant: 55 to 65% of revenue

Quick service and fast casual: 50 to 60% of revenue

Delivery kitchen: 45 to 58% of revenue (lower front-of-house labor)

Prime cost above 65% is a signal that either food cost, labor, or both are out of control and need attention.

Net profit margin

Net profit margin = net income divided by total revenue x 100

Net profit is what remains after all costs: food, labor, rent, utilities, marketing, insurance, equipment, and taxes. It is the actual profit of the business.

Restaurant net margins are notoriously thin. Industry averages in the US:

Full-service restaurants: 3 to 9%

Quick service: 6 to 12%

Delivery kitchens: 8 to 15% (lower overhead potential)

A 10% net margin is considered healthy. A 5% margin is viable but leaves little room for unexpected costs.

How the three metrics relate

Start with gross margin (food cost control). Then track prime cost (food plus labor). Then monitor net margin (total operational health).

You can have a healthy gross margin and still have poor net profit if rent is too high, labor is inefficient, or other overhead is unchecked. Work the layers in sequence.

What moves net margin most

Revenue volume: fixed costs (rent, equipment) do not rise proportionally with revenue. More sales spread fixed costs across more orders, improving net margin.

Labor efficiency: scheduling, cross-training, and limiting overtime affect prime cost more than most operators realize.

Occupancy cost: rent is often the hardest cost to change but has the biggest impact when it is too high relative to revenue.

Frequently asked questions

What is a good profit margin for a restaurant? Net margins of 5 to 10% are healthy. Below 3% leaves almost no buffer for unexpected costs or downturns. Above 15% is possible in well-run, high-volume, or delivery-focused operations.

Is gross margin the same as gross profit? No. Gross margin is a percentage. Gross profit is a dollar amount. A dish with $6.30 gross profit on a $9.00 sale has a 70% gross margin.

Does Dishboard calculate net margin? No. Dishboard calculates food cost, gross profit, and delivery channel margins. Labor, rent, and other overhead are outside its scope.
