Standard costing is a management-accounting technique that assigns predetermined costs to materials, labour and production overhead before production takes place. Businesses then compare those standards with actual results to identify cost variances and investigate what caused them.
A variance does not automatically mean that a department performed well or poorly. A higher material cost, for example, could result from supplier-price changes, improved material quality, an inefficient purchasing decision or a combination of factors. Standard costing is most useful when businesses investigate the cause rather than looking only at whether the variance is favourable or adverse.
Standard costs can support budgeting, pricing, inventory costing and operational control. For financial reporting under IFRS, however, additional requirements apply when standard costs are used to measure inventory.
This guide explains how standard costing works, how to calculate standard costs and variances, when standards should be updated, and how Saudi manufacturers can use ERP data to strengthen cost control.
Standard costing is a management-accounting technique in which a business establishes predetermined costs for materials, labour and production overhead. Actual results are then compared with these benchmarks to identify and analyse variances.
For example, a manufacturer may establish that one unit should require:
Production data can then show whether the actual price, quantity, labour time or overhead differs from those standards.
Standard costing is primarily useful for planning, cost control, performance analysis and operational decision-making. An adverse variance does not automatically prove inefficiency, and a favourable variance does not automatically indicate good performance. The underlying cause must be investigated.
Yes, but with an important condition.
Under IAS 2, businesses may use the standard-cost method as a technique for measuring inventory when the resulting amount approximates actual cost. Standards should take into account normal levels of:
The standards should also be reviewed regularly and revised when current conditions make the existing assumptions inaccurate.
Inventory must still comply with the wider IAS 2 requirements, including measurement at the lower of cost and net realisable value.
But which industries or businesses can benefit most from adopting this method? Let’s explore.
Standard costing is most useful where businesses can define repeatable quantities, labour times, processes or overhead assumptions.
Common applications include:
Retail businesses may also use cost-measurement techniques, but standard costing should not be confused with inventory cost formulas. Under IAS 2, interchangeable inventory is generally assigned cost using FIFO or weighted average. LIFO is not permitted under IFRS.
To better understand how standard costing fits into your overall financial strategy, let's take a moment to compare it with a budget. Here's how they differ.
Standard costs and budgets work together, but they serve different purposes.
A standard cost represents the expected cost of a unit, activity or input. A budget translates expected activity levels into an overall financial plan.
For example, if the standard production cost of one unit is SAR 100 and the business plans to manufacture 10,000 units, the standard cost may help build the production-cost portion of the budget.
A budget may therefore use standard costs, but the two concepts are not interchangeable.
Standard costing relies on three main components to set accurate cost benchmarks. Let’s break them down:
This refers to the raw materials used in production. Businesses set a standard cost for materials based on expected prices and usage. For example, if you manufacture furniture, the standard cost for wood might be SAR 50 per unit, depending on supplier contracts and quality specifications.
By comparing actual material costs with the standard, you can identify if you’re overpaying or using more materials than planned.
Labor costs include wages paid to employees directly involved in production. The standard cost for labor is calculated based on the time required to produce a product and the wage rate.
For instance, if it takes 2 hours to make a product at a rate of SAR 25 per hour, the labor standard is SAR 50. Any difference between actual labor costs and the standard indicates efficiency or inefficiency.
Production overhead includes indirect manufacturing costs that cannot be traced economically to an individual unit.
These are generally divided into:
When standard costs are used for financial-reporting inventory measurement under IAS 2, fixed production overhead should reflect normal production capacity. Businesses should not increase the fixed overhead assigned to each unit simply because production was unusually low or the factory experienced abnormal idle time.
A product’s standard manufacturing cost is built from the expected quantity and price of each production input.
Standard material cost = Standard quantity × Standard material price
Standard labour cost = Standard labour hours × Standard labour rate
Production overhead is then added using the organization’s defined allocation basis.
The standard manufacturing cost per unit can be expressed as:
Standard cost per unit = Standard direct materials + Standard direct labour + Standard production overhead
For example, if one product requires:
The standard manufacturing cost is:
SAR 60 + SAR 45 + SAR 12 + SAR 18 = SAR 135 per unit
Standards should represent normal operating conditions rather than ideal conditions that employees cannot realistically achieve.
Let’s see how these standard costs apply in a real-world example to understand better.
Here’s an example of how to calculate the standard cost for manufacturing a custom metal chair:
Metal Sheets: 20 kg per chair at 2,700 SAR/ton (approx. 54 SAR).
Wood (for armrests): 2 kg at 500 SAR/ton (approx. 1 SAR).
Nails/Screws: Estimated at 5 SAR per chair.
Total direct materials = 60 SAR
Each chair takes 1.5 hours to produce.
Labor cost = 30 SAR/hour
Total labor cost = 45 SAR
Factory rent, utilities, equipment depreciation, and other costs average 30 SAR per unit.
Total overhead = 30 SAR.
Using the formula, Standard Cost = Direct Materials + Direct Labor + Manufacturing Overhead
Standard Cost per Chair = 60 + 45 + 30 = 135 SAR
Now, let’s explore how variance analysis helps you identify inefficiencies by comparing actual costs with expected ones. This is where you really get to see the impact of your cost management efforts.
Variance analysis compares actual performance with the standards established for the actual level of production. Instead of looking only at the total cost difference, finance and operations teams can break it into individual causes.
For a cost variance:
However, the label does not explain whether the underlying decision was good or bad.
For example, cheaper material could create a favourable material price variance while producing more waste, rework or defects and creating an adverse material usage variance.
Similarly, paying experienced employees a higher hourly rate could create an adverse labour-rate variance but improve labour efficiency.
Variance analysis should therefore answer three questions:
Corrective action should be based on those answers—not simply on whether the variance is favourable or adverse.
Having established how variance analysis works, let’s now explore the broader benefits of adopting standard costing in your business.
Adopting standard cost accounting can yield significant benefits for your business. Here’s how it can enhance your financial strategies:
Despite its advantages, businesses can face several challenges when implementing standard costing. Let’s look at some of the common obstacles.
Standard costing is useful only when the standards remain credible and the resulting variances are interpreted correctly.
Supplier prices, wage rates, production methods, freight costs and equipment capacity can change. If standards are not reviewed, management may spend time investigating variances caused by outdated assumptions rather than current performance.
Standards that assume perfect output, zero waste or unrealistic labour efficiency can create recurring adverse variances even when production is operating normally.
Standards should reflect normal operating conditions and should be revised where current conditions materially change.
A favourable purchasing decision may cause an adverse production variance. For example, lower-quality materials may cost less but increase waste or labour time.
Managers should therefore evaluate related variances together rather than assigning responsibility based on one number.
Businesses producing many product variants may need separate BOMs, routings, labour assumptions and overhead rates. Maintaining this level of detail can be difficult without integrated manufacturing data.
Standard cost may be used to measure inventory when it approximates cost, but inventory must still comply with the applicable accounting framework.
Recoverable taxes, such as recoverable input VAT, are generally excluded from inventory purchase cost under IAS 2. Abnormal waste and certain other costs are also expensed rather than included in inventory.
Employees may optimize the metric rather than the business outcome—for example, purchasing excessive quantities solely to obtain a lower material price.
Variance reports should therefore be considered alongside quality, delivery, inventory, throughput and customer-service measures.
Now, let’s move on to the steps to implement standard costing in your business.
Here’s a simple approach to successfully implementing standard costing in your business:
Decide what the standard will measure: a finished product, batch, work order, production stage or service.
Use the current BOM, routing, supplier information, labour rates, expected production time and normal production capacity.
For each product, define:
Actual results should come from the same underlying production process used to build the standard.
An integrated manufacturing system can connect:
This creates a stronger basis for comparing the expected and actual cost of production.
Calculate material, labour and overhead variances for the reporting period. Use the standard quantity or hours allowed for actual output, rather than comparing actual production costs with the original budget without adjusting for production volume.
Set thresholds so managers focus on differences large enough to require investigation.
Determine whether the cause relates to:
A variance should be investigated by the team able to influence its underlying cause. Avoid automatically assigning responsibility to purchasing or production based solely on the variance name.
Review standards regularly and whenever material changes occur in supplier pricing, product design, BOM quantities, labour requirements or manufacturing processes.
Do not revise standards merely to eliminate an adverse variance. Changes should reflect a genuine change in normal operating conditions.
Implementing standard costing can be challenging without the right tools. Luckily, there are software options that make it easier to track and manage costs in real-time. Let’s look at the popular ones.
Standard costing becomes much easier to maintain when financial and production data come from the same system.
For manufacturers, useful ERP capabilities include:
HAL Manufacturing ERP connects BOMs, production scheduling, inventory and financial information across the manufacturing cycle.
HAL currently documents:
These capabilities can support a standard-costing process by giving finance and production teams reliable operational data for establishing standards and investigating variances.
The accounting team should still determine the organization’s standard-cost methodology, overhead-allocation policy and financial-reporting treatment under the applicable SOCPA-endorsed accounting framework.
Standard costing gives businesses a structured way to compare expected production costs with what actually happened.
The process starts with realistic standards for materials, labour and production overhead. Variance analysis then helps explain differences in price, quantity, labour efficiency, overhead and production volume.
The key is not simply producing a favourable variance. Effective cost control requires understanding why the variance occurred and whether it represents a sustainable improvement.
For businesses applying IFRS, standard costs may also be used as an inventory cost-measurement technique when they approximate cost and are regularly reviewed against current operating conditions.
Manufacturers with complex BOMs, work orders and production flows can benefit from connecting costing data directly with production activity. HAL Manufacturing ERP provides work-order cost tracking, BOM management and planned-versus-actual production analysis to support this process.
Request a HAL ERP demo to explore how HAL can connect manufacturing, inventory and financial data for clearer production-cost control.
Yes. IAS 2 allows the standard-cost method as a technique for measuring inventory when the results approximate cost. Standards should reflect normal levels of materials, labour, efficiency and capacity utilisation and should be reviewed and revised when necessary.
Standard cost is the predetermined amount a product or activity is expected to cost under defined operating assumptions. Actual cost is the cost that was actually incurred.
The difference between them creates a cost variance that can be analysed further.
No. Standard costing normally establishes costs for a unit, input or activity. A budget combines expected costs with sales volumes, revenue, operating expenses, capital expenditure and other assumptions to create an overall financial plan.
Common variances include:
No. A favourable variance means the measured result is better than the standard from a cost perspective, but the reason still needs to be investigated.
For example, buying cheaper materials may create a favourable price variance but increase defects or waste.
There is no universal monthly or annual rule. Standards should be reviewed regularly and when material changes occur in prices, BOMs, labour requirements, capacity or production methods.
For inventory measurement under IAS 2, standards should be revised when necessary to reflect current conditions.
Businesses applying IFRS cannot use LIFO as an inventory cost formula. IAS 2 generally requires FIFO or weighted average for interchangeable inventory.
Standard costing is a measurement technique rather than an alternative cost-flow formula.
ERP systems can capture the material, labour, overhead and production data required for variance analysis. The precise functionality depends on the system configuration.
Manufacturing ERP is particularly useful when it connects BOMs, work orders, inventory transactions and accounting data in the same workflow.
