Standard cost is how much a product is expected to be produced under normal conditions; The actual cost shows the cost actually incurred when production is completed. The difference between the two amounts is not just a result of "we produced expensively". The real reason for the difference cannot be found without separately examining the material price, consumption amount, labor time, wastage, capacity and general production expenses.
Standard Cost and Actual Cost Do Not Answer the Same Question
Standard cost: What should it be?
It is the control value determined before production with the assumptions of normal material price and quantity, expected labor time, normal waste, efficiency and capacity.
Actual cost: What was incurred?
The real purchase price is formed at the end of production based on the materials given to production, working time, wastage, solid quantity produced and distributed expenses.
How to Determine Standard Cost?
Standard cost is not just copying the average of the past period. The bill of materials, expected purchase price, operation times, normal wastage, labor charges, machinery usage and manufacturing overhead should be brought together with the same period assumptions.
standard material
bill of materials quantity, normal wastage and material price determined for the period.
standard workmanship
The equivalent of operating time and normal hourly labor costs.
standard machine
Expected machine share based on normal operating time and capacity level.
Standard overhead
Planned share of energy, maintenance, depreciation and other production expenses.
Where did the 110 TL Cost Difference for the Same Product Come From?
The amounts below are an explanatory example prepared for a single solid product. It is not a financial record or calculation tool.
| Cost component | Standard | Actual | Difference | First reason to examine |
|---|---|---|---|---|
| Raw material and supplies | 620 TL | 690 TL | +70 TL | Purchase price, excess consumption or wastage |
| direct labor | 180 TL | 195 TL | +15 TL | Processing longer than planned or working overtime |
| General production expense | 200 TL | 225 TL | +25 TL | Low capacity utilization or expense increase |
| Total unit cost | 1,000 TL | 1,110 TRY | +110 TL | Total negative cost variance |
In this example it is wrong to attribute the total variance solely to material price. The 70 TL on the raw material line must be broken down from purchase price, excess consumption or waste based on source movements. The distinction on the purchasing side in the purchase price difference guide and review it.
Why Does Actual Cost Differ From Standard Cost?
Material price difference
It is the difference between the standard price and the actual purchase and additional costs. Purchase condition, exchange rate, shipping or supplier change may have an impact.
Material quantity difference
It is the difference between the expected consumption in the bill of materials and the consumption realized in production. Waste, quality loss and wrong measurement unit are investigated.
Labor time difference
The standard operating time is compared with the actual working time. The process of waiting, reworking and learning can change the outcome.
Labor wage difference
It is the difference between the planned hourly rate and the actual rate that depends on shift, overtime or employee qualification.
General expense variance
Shows the deviation of energy, maintenance, depreciation and other production costs from the budgeted amount.
capacity difference
It is the increase in unit cost by distributing fixed production costs to fewer solid products than planned.
A negative variance is not always inefficiency
Higher quality requested by the customer, faster transportation or deliberate overtime selected for urgent orders may increase the cost. Whether the difference is acceptable or not should be evaluated based not only on the amount but also on the reason for the decision taken and the order result.
How to Find the Source of Cost Variance in Four Steps?
Make the difference visible
Juxtapose standard and actual amount by product, production order, operation, and cost component.
Separate price from quantity
Was material purchased at a high price, or was more consumed than planned? The same total variance can have two separate causes.
Go to the source record
Verify purchase invoice, consumable movement, labor time, wastage, downtime and solid production quantity.
Separate action and standard
Fix the repetitive operation problem; Update the standard in a controlled manner in case of permanent market or method change.
Saying "material cost increased" alone is not sufficient
+70 TL material
Standard and actual material cost are separated.
+25 TL purchase effect
The invoice price is compared to the standard price.
+45 TL consumption effect
bill of materials, actual consumption and wastage are checked.
Two different responsible processes
Purchasing price and production consumption are improved separately.
When Should Standard Cost Be Updated?
Standard cost is fixed enough to make variance visible; It must be vivid enough to represent current production conditions. It should not be changed after each one-time difference, but should be reviewed in a controlled manner for the following permanent changes.
In the TMS 2 statement of the Public Oversight Institution, it is stated that standard costs must take into account normal material, labor, productivity and capacity levels; be regularly reviewed and, if necessary, redefined according to current conditions. The accounting and valuation method to be used by the company should also be evaluated with the accountant or relevant experts.
What Records Should There Be in ERP for Standard and Actual Cost?
Product and bill of materials version
Standard quantity, wastage allowance, alternative material and validity date.
Purchasing and accepting goods
Standard price, order price, actual purchase, exchange rate, shipping and additional expenses.
Production order and consumables
Planned quantity, materials given to production and returned, wastage and intact product.
Operation and labor
Standard time, actual time, employee, shift, waiting and rework.
Machine and capacity
Planned work, actual work, downtime and solid quantity produced.
Cost period
Standard release, distribution key, closing date and deviation confirmation.
The reliability of the actual cost depends on the actual consumption and time records in the production order. record chain in the production order guide; components of the total product cost In the product cost calculation article; The machine share is in the machine hour cost guide and review it.
Common Mistakes in Standard and Actual Cost Comparison
Link every variance to a purchase
Even if the unit price remains the same, excess consumables, wastage or incorrect bills of materials may increase the material cost.
Never change the standard
A standard that works with old prices and times ceases to be the target to be achieved and makes the report meaningless.
Changing the standard after each production
If a temporary malfunction or one-time emergency purchase is immediately brought to the standard, the problem is normalized.
Just look at the total difference
The correct responsible person and action cannot be found without separating the price, consumption, time, wastage and capacity resources of the total 110 TL difference.
Leaving the actual record incomplete
If material consumption, intact product, wastage or working time are estimated later, the actual cost does not reflect the truth.
Turning the cost difference into a performance penalty
The deviation report is first to understand the process; Attributing unverified difference directly to individual performance degrades recording quality.
Frequently Asked Questions
Are standard cost and budget cost the same?
Not always. Can plan budget period totals; Standard cost is the control value that represents normal production conditions on the basis of product, bill of materials and operation.
When is the actual cost calculated?
Once the required material, labor, production result and expense records are completed, the production order can be calculated on a batch or period basis. If there are incomplete records, the result should be considered provisional.
Is positive cost variance always success?
No. Lower material consumption may result from incomplete processing or quality degradation, while lower labor time may result from incomplete registration. The result must be verified by quality and production quantity.
Can standard cost be used in the sales price?
It can provide a starting point for the offer and price decision; however, factors such as the current exchange rate, order-specific costs, discount, capacity, and target profit must be evaluated separately. The impact of these conditions on the sales outcome in the order profitability guide and review it.
