7 Expenses Businesses Pay but Fail to Include in Cost Calculations
Many companies are confident that they know the true cost of their products or services. They calculate raw materials, employee salaries, and delivery expenses, then add the desired profit margin to determine the selling price. However, at the end of the month, they often discover that although sales are growing and the team is busy, the actual profit is much lower than expected. One common reason is an incomplete cost calculation. Businesses incur many expenses but fail to connect them to a particular product, service, or customer order. These costs remain recorded under general accounting categories and are not taken into account when prices are determined. As a result, a company may achieve high sales volumes while earning very little profit from each transaction–or even selling at a loss. Below are seven expenses businesses frequently overlook when calculating the true cost of their products or services.
1. Management and Administrative Staff Time
The salaries of employees directly involved in production or service delivery are usually included in the cost calculation. However, the time spent by directors, sales managers, administrators, accountants, and other office staff is often treated simply as a general business expense. For example, to complete a customer order, the director may participate in negotiations, the sales manager may prepare a commercial proposal, the administrator may collect the necessary documents, and the accountant may issue an invoice and follow up on payment. All these activities require time and money. When administrative expenses are not allocated across orders or services, the company underestimates the real cost of its operations. A relatively simple allocation method can be used. The total monthly cost of administrative salaries may be distributed based on working hours, number of orders, revenue, or another indicator appropriate for the company’s business model.
2. Work Performed Before the Sale
Many companies begin calculating costs only after the customer confirms an order. However, by the time the contract is signed, the business may already have invested significant resources. These resources may include meetings, consultations, preliminary calculations, free samples, preparation of commercial proposals, price negotiations, and contract reviews. Moreover, not every negotiation results in a sale. Out of five potential customers, perhaps only one places an order. Nevertheless, the time and resources spent on the other four prospects must also be financed from the revenue generated by successful sales. Therefore, sales-related expenses and pre-contract work should be included either in the cost of successful transactions or, at a minimum, in the company’s profitability analysis.
3. The Cost of Errors, Rework, and Returns
When a product is manufactured incorrectly, an order must be redone, or a service has to be provided again, the business incurs additional expenses. However, these costs are rarely included in the original cost calculation. For example, a manufacturer may need to use additional raw materials, pay employees for extra work, and arrange delivery for a second time. A service company may spend several additional hours correcting a document, revising calculations, or resolving a customer issue. Even when the original error occurred during a previous month, the cost of fixing it may arise in the current reporting period. Unless such cases are tracked separately, management cannot know how much it actually costs to complete and support one order. Returns, free rework, warranty services, and employee hours spent correcting errors should therefore be recorded and monitored separately.
4. Equipment Depreciation and Maintenance
Many businesses include only expenses for which they have recently made a payment. If equipment was purchased two years ago, it may appear that using it today costs nothing. In reality, every piece of equipment has a limited useful life. It gradually wears out, requires maintenance, repairs, spare parts, and software updates. Eventually, it will need to be replaced. If the equipment’s cost is not allocated over its useful life, the selling price will not generate enough resources for the company to purchase replacement equipment in the future. The cost calculation should therefore include not only accounting depreciation but also the economic cost of equipment maintenance and future replacement.
5. Small but Recurring Expenses
Some expenses seem insignificant when considered individually, but together they can represent a substantial amount. Examples include bank fees, packaging materials, stationery, printing, telephone services, software subscriptions, online platform fees, courier services, and transportation expenses. Because these payments occur on different dates and are often incurred by different departments, companies do not always connect them to the products sold or services provided. However, if these small recurring expenses account for 4–5% of monthly revenue, ignoring them may significantly distort the company’s profitability figures. This is where properly organized accounting services in Armenia become especially important. Detailed analytical accounting helps businesses identify not only major payments but also small recurring expenses that gradually accumulate into a significant amount.
6. Unused Capacity and Downtime
A company may employ five people, rent production premises, and own equipment but use only 60% of its available capacity during a particular month. It still pays salaries, rent, utilities, and other fixed expenses for the remaining 40%. If cost calculations include only expenses directly related to completed orders, the cost of unused capacity remains outside the calculation. For example, a workshop may be capable of producing 1,000 units per month but actually produce only 500. If rent and management expenses are allocated across the theoretical production capacity of 1,000 units, the calculated cost per unit will be artificially low. In reality, the expenses must be financed by the 500 units actually produced and sold. Businesses should therefore distinguish between normal production capacity, actual capacity utilization, and the cost of downtime.
7. Post-Sale Customer Service Expenses
The work does not always end when the sale is completed. Customers may call with questions, request additional documents, ask for changes, require training or technical support, or seek an extension of the payment deadline. Some customers require significantly more attention than others, even though they pay the same amount. Nevertheless, businesses often apply identical prices without considering differences in the actual cost of customer service. This is particularly important for service companies. They need to evaluate not only the main service-delivery stage but also the customer’s entire service cycle–from the first meeting and proposal preparation to final payment and post-sale support. Experienced accounting companies in Armenia often recommend analyzing revenue and expenses not only by service category but also by customer, project, department, or responsible employee. This approach helps identify which customers are genuinely profitable.
How to Calculate a More Accurate Cost
To calculate costs correctly, expenses should generally be divided into three categories: direct costs, indirect costs, and hidden or regularly unallocated costs. Direct costs can be linked immediately to a particular order. These include raw materials, production labour, and direct delivery expenses. Indirect expenses–such as rent, management, accounting, and software—should be allocated using a reasonable and consistent method. The cost of errors, returns, downtime, and free customer support should be monitored separately. It is not enough to know how much money the company has spent. Management also needs to understand which product, service, customer, or project generated each expense. Once a business starts calculating its complete cost, it may discover that its best-selling product is not necessarily its most profitable one. A customer generating high revenue may require so much additional work that the actual profit from that relationship is close to zero.
Accurate cost calculation is not merely an accounting figure. It is an essential tool for pricing, expense control, profitability analysis, and the long-term financial stability of the business.
