Estimated restaurant operating profit is monthly sales minus the operating expense categories entered. Divide that estimate by monthly sales and multiply by 100 to calculate estimated operating margin.

Your restaurant estimate
A monthly operating estimate based only on the categories entered.
The estimate does not automatically calculate income tax, interest, depreciation, amortization, owner distributions, capital spending, or any category not entered. Use consistent accounting definitions and consult your financial records for formal reporting.
How is restaurant operating profit estimated?
Subtract food and beverage COGS, labor, occupancy, utilities, platform fees, technology, insurance, and other entered operating expenses from monthly revenue.
The remainder is an operating estimate based on those categories. It is not audited profit, cash flow, or automatically equivalent to net income because tax, interest, depreciation, amortization, capital spending, and omitted categories are not calculated for you.
The formula
- R
- Monthly restaurant sales or revenue
- OE
- Sum of the operating expense categories entered
- PC
- Prime cost = food and beverage COGS + labor
A $100,000 operating month
Suppose monthly revenue is $100,000. Entered expenses total $84,700: $30,000 COGS, $32,000 labor, $8,500 occupancy, and $14,200 across utilities, platforms, technology, insurance, and other operating expenses.
Estimated operating margin is 15.3%. Food and beverage cost is 30.0%, labor is 32.0%, prime cost is 62.0%, and occupancy is 8.5% of entered revenue. These are descriptions of the example, not industry targets.
Align every dollar to the same accounting period.
Use monthly sales and expenses from the same month. Enter zero when a listed category truly does not apply, and place costs not otherwise listed in other operating expenses. Avoid counting rent, fees, or software twice.
Be consistent about what labor includes and how COGS is measured. Comparing months is useful only when category definitions and timing stay comparable.
Each percentage isolates a different cost relationship.
Food cost percentage compares food and beverage COGS with revenue. Labor percentage compares entered labor with revenue. Prime cost percentage combines COGS and labor before dividing by revenue. Occupancy percentage compares rent or occupancy with revenue.
These ratios help locate changes, but none identifies a cause by itself. Sales mix, scheduling, purchasing, waste, pricing, fee mix, repairs, seasonality, and accounting timing can all move the result.
A positive estimate means entered revenue exceeds entered operating categories.
It does not prove the books are complete, the cash is available, or the business earned the same amount under formal accounting. Reconcile the estimate with your profit-and-loss statement and investigate missing or mistimed categories before acting on it.
Assumptions and limitations
This calculator assumes
- Revenue and every expense cover the same monthly period.
- Expense categories are entered in dollars and are not duplicated.
- Food and beverage COGS and labor use definitions consistent with your records.
- Other operating expenses captures applicable costs not listed separately.
Keep in mind
- The calculator does not automatically include tax, interest, depreciation, or amortization.
- It does not calculate cash flow, debt principal, capital purchases, or owner distributions.
- Missing accruals, inventory adjustments, or payroll liabilities can change formal results.
- This is an operating estimate, not audited profit or accounting advice.

Related questions
Is estimated operating profit the same as net income?
Not necessarily. This calculator subtracts only the visible operating categories you enter. Net income may also reflect interest, tax, depreciation, amortization, and accounting adjustments outside this tool.
What is prime cost in this calculator?
Prime cost is entered food and beverage COGS plus entered labor. The percentage divides that combined amount by monthly revenue.
Where should delivery commissions be entered?
Use delivery and platform fees for marketplace commissions and similar charges you want separated. Keep the definition consistent and do not repeat the same fees in other operating expenses.
Can the calculator show a negative operating margin?
Yes. When entered operating expenses exceed revenue, estimated operating profit and margin are negative. That is a valid mathematical result, not a calculation error.
