Restaurant Margin Estimator

1. Enter sales
Use net sales for the period, after discounts and refunds if that matches your reports.

2. Enter food and beverage cost
Use the direct product cost associated with the same period.

3. Add operating expenses
Combine labor, occupancy, supplies, utilities, and other operating expenses not already in product cost.

4. Compare margin levels
Gross margin isolates product cost, while operating margin includes the broader operating expense base.

5. Test a scenario
Adjust sales or costs to see how sensitive each margin is to operational changes.

Gross margin % = (Sales − Food and beverage cost) ÷ Sales × 100
Operating margin % = (Sales − Food and beverage cost − Operating expenses) ÷ Sales × 100

Sales must be greater than zero for meaningful percentage interpretation. Expense classification should remain consistent across periods.

What the result means

Use the main result together with the supporting metrics to compare scenarios and identify the assumptions with the largest effect.

Sales must be greater than zero for meaningful percentage interpretation. Expense classification should remain consistent across periods.

Given
Given: $200,000 sales, $62,000 food and beverage cost, and $116,000 operating expenses.

Calculation
Gross profit = $200,000 − $62,000 = $138,000. Gross margin = $138,000 ÷ $200,000 × 100 = 69%. Operating profit = $138,000 − $116,000 = $22,000. Operating margin = 11%.

Result
The restaurant retains 69% after product cost and 11% after the entered operating expenses.
