Overhead costs refer to the expenses necessary to run a business, regardless of whether the company is handling a large number of orders or operating at a minimal pace. Properly managing these overhead costs allows businesses to offer better prices for their products or services and discover ways to reduce costs and streamline their business model. However, these benefits are only achievable if the accounting staff keeps detailed and accurate records. Read on to learn the best methods for calculating overhead costs.
Steps
Identifying Overhead Costs

- In our example, indirect expenses such as postage fees and insurance are necessary for the business to function but are not direct costs of producing the product.
- When calculating overhead costs, always consider whether the cost is fixed or variable. Fixed costs remain constant, while variable costs fluctuate depending on the company's activity level and production volume.

- The most common direct costs, as mentioned earlier, are wages and raw materials.
- Simply put, direct costs are paid for things that appear on the production line, while indirect costs are paid for the 'production line' itself.

- Set a fixed period for consistency. If you calculate indirect costs monthly, you should also calculate direct costs monthly.
- Consider using programs like QuickBooks, Excel, or FreshBooks to help manage your data more effectively and efficiently.
- Don’t worry about where to place each cost just yet. It’s essential to get an overall cost picture before calculating your overhead costs.

- Review past cost reports and invoices to ensure no expense is overlooked.
- Don’t forget about recurring costs, like renewing licenses or submitting forms. Although these costs may appear infrequently, they are still considered overhead costs.

- If you have past accounting data, you can use it for your budget for the coming year. The figures in your plan often remain the same from year to year, unless you make significant changes to your business plan.
- Take an average of the costs over 3 to 4 months to minimize the effect of any unusual costs.

- If you’re still confused about the categorization, think of overhead costs as those expenses you’d have to pay even if you stopped production immediately. So, which costs would be considered overhead?
- Keep this list updated whenever you encounter new costs.

Gain a deeper understanding of Overhead Costs

- First, divide the indirect costs by the direct costs. In this example, the overhead ratio is 0.35 (16,800 / 48,000 = 0.35).
- Next, multiply this number by 100 to get the percentage of overhead costs. In this case, the percentage is 35%.
- This means your company spends 35% of its total costs on overhead expenses like legal fees, administrative salaries, rent, etc., for each product produced.
- The lower the overhead costs, the higher the profit. Thus, a low overhead percentage is desirable.

Leverage Overhead Costs to Improve Business Performance

- If this ratio is low, it indicates that your company is managing costs effectively.
- If it's high, your company may be employing too many staff members.

- For example, if my company sells $100,000 worth of soap every month and I pay $10,000 to cover overhead, this means I'm spending 10% of revenue on overhead costs.
- The higher this percentage, the lower the profit margin.

- All industries and companies have overhead costs, but those who manage them effectively tend to generate higher profits.
- However, high overhead isn’t always negative. If you're investing in quality equipment or satisfying employees, you may achieve higher productivity and greater profits.
Advice
- If you're calculating past overhead costs, you can use existing data to perform the calculations. If you want to estimate future overhead, you'll need to use average figures. For example, to calculate future indirect costs, gather data from several past accounting periods to find the average indirect costs for each category that may arise in the future. Similarly, for direct costs, estimate the average cost based on current and past data. For instance, direct labor costs can be calculated by multiplying the average hourly wage by the average number of working hours over a period. The result may not be exact, but it will provide a close estimate.
- Continuously track the overhead cost ratio – monthly, quarterly, and annually – to mitigate the impact of fluctuations caused by cycles, buying psychology, and the availability/cost of raw materials.
Warning
- The steps outlined above are designed to assist you in better analyzing quantitative data. Each company has its own unique characteristics, so optimizing overhead costs is not an exact science.
