Restaurant Profit and Loss Statement: Six Numbers to Investigate
A restaurant profit and loss statement tells you how a period performed. The next job is tracing a variance to the records behind it. A group total can hide a location that needs attention; a location total can hide a particular shift or transaction.
Use these six checks alongside your P&L. Some belong in supporting operating reports rather than separate general-ledger lines.
Read the statement from sales to net income
This simplified monthly statement for hypothetical Location A illustrates the arithmetic. It is not a customer result, benchmark or recommended chart of accounts. Have accounting confirm classifications and reporting basis.
| Line | Hypothetical amount | How to read it |
|---|---|---|
| Net sales | $100,000 | Sales after the adjustments included in this example's definition |
| Cost of goods sold | ($30,000) | Inventory cost consumed during the period |
| Gross profit | $70,000 | Net sales minus COGS |
| Labor | ($32,000) | Agreed wage, tax and benefit categories |
| Other operating expenses | ($25,000) | Occupancy, utilities and other operating costs, excluding depreciation here |
| Depreciation | ($3,000) | Separate noncash expense in this example |
| Operating income | $10,000 | $70,000 − $32,000 − $25,000 − $3,000 |
| Interest | ($1,000) | Financing cost |
| Income tax expense | ($2,000) | Illustrative accounting provision, not a tax calculation |
| Net income | $7,000 | Result after the listed expenses |
Net income is not the bank-balance change. Debt principal, capital purchases and working-capital timing need separate analysis. Likewise, overtime details, cover counts and individual voids belong in supporting schedules; do not subtract them again when already included in labor or net sales.
Read the six checks below as explanations of statement lines, not six additional expenses.
For the percentage calculation behind the labor line, use the restaurant labor cost calculator. A gap to target is not proof of recoverable savings.
Labor cost: separate the numerator from the denominator
A higher labor percentage can reflect more paid hours, higher wage rates, lower sales, or a mixture. Compare labor dollars, hours and net sales before deciding staffing is the problem. Keep the definition consistent: wages alone and wages plus payroll taxes and benefits are different measures.
Break the variance down by location, role and daypart. Compare similar trading periods and account for training, opening activity and unusual service demands. A group-wide target is a starting point for questions, not proof that every location should perform identically.
Overtime: trace the hours and their cause
Review overtime separately in the supporting labor report even if the P&L combines it with wages. Compare scheduled hours, actual hours, coverage changes and edit history. Do not assume that overtime was avoidable or that a manager edit proves misconduct.
Changing future staffing cannot erase hours already worked. U.S. federal guidance requires covered employees to be paid for compensable work; state and local rules can add requirements. Department of Labor.
Voids and comps: check the POS definitions
Read reason codes, approval records and individual checks. POS definitions differ, and a voided item is not automatically cash that can be recovered. Avoid double-counting adjustments already included in net sales. Ask your accountant how the operational report reconciles to the ledger.
Cost of goods sold: inspect the inventory bridge
Purchases alone do not show everything consumed. Under an inventory-based calculation, beginning inventory and purchases are reconciled with ending inventory and relevant adjustments. The IRS describes the underlying inventory calculation in its small-business guide. IRS Publication 334.
Check count dates, transfers, credits and unit sizes before attributing a variance to waste or theft.
Revenue per cover: add operational context
Use this beside the P&L when cover data is reliable. Keep sales and cover definitions aligned across periods. A lower average check can reflect mix; an empty seat is a potential opportunity, not a receivable or guaranteed lost profit.
Use the cash-reconciliation workflow to follow a cash difference through its supporting records; the bank trail is separate from the P&L.
Cash over/short: keep unresolved items visible
Follow cash from the POS close through the count, deposit record and bank posting. A missing match may be a timing difference or recording error. Separate confirmed shortages from deposits in transit, and retain the evidence for each resolution.
Put the findings to work
Turn a supported P&L variance into an owned action and check the next comparable period. Marty is a managed profit-control layer using Find → Assign → Follow up → Verify. Its paid Cash Recovery Plan establishes the baseline; optional Managed Profit Control monitors agreed controls, alerts managers, follows up, escalates missed actions and verifies results.
