CMV is the Brazilian abbreviation for cost of goods sold (COGS). In an industrial kitchen, the indicator usually represents the cost of the food actually consumed in delivering the service. It is not the same as the amount purchased in the month, and it does not automatically include labour, rent or administrative expenses.
The sum is simple on paper, but it needs reliable stock, receipts with a value, recorded issues and revenue for the same period. Without these, the percentage can look exact and still lead to the wrong conclusion.
What COGS is in an industrial kitchen
Direct answer
COGS is the cost of the food consumed in the period or service being analysed. A purchase increases stock. The cost enters the result when the ingredient is consumed, written off or recorded as a loss, according to the policy adopted.
CPC 16 (the Brazilian accounting pronouncement on inventories) treats raw materials and supplies that have not yet been used as stock. This helps separate cash flow from consumption. Buying a large lot on the last day of the month should not, on its own, raise that month's COGS if the material stayed in storage.
The scope of the indicator must be identified. Food COGS is different from the full cost of the operation. If the analysis includes labour, utilities, depreciation and other items, the indicator must be presented as total cost or under another name defined by the company.
Periodic COGS formula
In the simplified periodic calculation, you start from opening stock, add net receipts and subtract closing stock. Returns, transfers, adjustments and losses must follow the accounting and operational policy adopted. The formula does not correct a poor physical count.
Opening and closing stock must be valued using the same method. A count in different units, an item with no conversion or an invoice recorded with the wrong cost will affect the result. For that reason, the calculation record must allow you to trace the movements that made up each balance.
COGS = opening stock + net receipts - closing stock
COGS percentage = food COGS / corresponding revenue × 100
Use the same accounting period and state whether revenue is gross or net.How the moving average cost works
The moving average cost is recalculated whenever a new receipt changes the value and quantity on hand. Later issues use the average cost in force at that moment. This method avoids arbitrarily choosing the price of one specific invoice for each consumption.
The valuation method does not replace lot and expiry control. The operation may physically pick the lot that expires first and, at the same time, use average cost as its valuation method. These are decisions with different purposes.
New average cost = (value of previous balance + value of receipt) / (previous quantity + quantity received)
Cost of issue = quantity issued × average cost in forceSources for this section: [1]
Theoretical COGS and actual COGS
Theoretical COGS comes from the recipe sheets, portions and reference quantities. It answers how much should be consumed according to the recorded standard. Actual COGS comes from recorded issues, losses and returns. It answers how much cost was recognized in execution.
The difference between actual and theoretical does not automatically identify the cause. It may reflect yield, ingredient substitution, portioning, price, loss, data entry error, a missed issue or an unrecorded return. The indicator guides the investigation; it does not replace analysis of the event.

| Measure | Source | Use |
|---|---|---|
| Theoretical COGS | Recipe sheet and planned quantity | Compare standard and execution |
| Actual COGS | Stock issues, losses and returns | Recognize the recorded consumption |
| Variance | Actual COGS minus theoretical COGS | Locate where to investigate |
How to interpret the percentage
A COGS percentage must be read together with revenue, volume, menu mix, ingredient prices, losses, data completeness and the recognition criterion. There is no ideal percentage that applies to all industrial kitchens.
A fall may indicate better use of ingredients, but it may also appear when issues were not recorded or when revenue includes amounts with no matching cost. A rise may come from price, menu, losses or an incomplete accounting period. The first question should be whether the numerator and the denominator represent the same period and scope.
- Compare the same Unit, accounting period and cost policy
- Confirm that revenue corresponds to the services that generated the consumption
- Check counts, issues, losses, returns and transfers
- Separate price variance from quantity variance
- Check data completeness before ranking Units
Example of a monthly calculation
A Unit started the month with R$ 18,000 in stock. It received R$ 42,000 in net receipts and ended with R$ 16,000. Periodic COGS is R$ 44,000. If the corresponding net revenue was R$ 110,000, the COGS percentage is 40%.
The example shows the formula and does not set a target. Before comparing this percentage, you would need to check the closing count, the recording of losses, the accounting period of the revenue and the method used in the other Units.
COGS = R$ 18,000 + R$ 42,000 - R$ 16,000 = R$ 44,000
COGS percentage = R$ 44,000 / R$ 110,000 × 100 = 40%Errors that make COGS unreliable
The most common mistake is to use purchases as consumption. Other problems appear when the count does not reconcile, the unit of measure is wrong or a return is treated as a new purchase. When an ingredient goes back to usable condition, this must be recorded so that the consumption cost does not stay inflated.
It is also risky to compare two Units that use different methods. One may recognize losses separately while another leaves them inside consumption. One may use net revenue and another gross revenue. Without reconciling the policies, the ranking does not measure comparable performance.
- Treating every purchase as COGS for the period
- Ignoring closing stock or using an unvalidated count
- Mixing units and conversions
- Not recording losses, returns and transfers
- Comparing different revenue and accounting periods
- Including indirect costs without changing the name of the indicator
How MEPO handles this topic
MEPO records receipts, issues, losses, returns, adjustments, transfers and counts. The moving average cost is recalculated on confirmed receipts. Profitability uses actual issues and keeps actual COGS, losses and theoretical cost separate. The screen shows when measurements, requisitions, costs or allocations are incomplete. MEPO is not presented as an accounting certification.
