You’ve decided to set up a small business, and you’ve already identified some of the most profitable products to sell online. The next step is figuring out how much you’re going to charge for those items so that you can raise your profit margin, but also be competitive. Knowing how to calculate product cost is the key to any successful pricing strategy. This step-by-step guide will walk you through that calculation so that you can plan production more accurately and set prices based on facts rather than just estimates.

How to Calculate Product Cost: A Step-by-Step Guide
The core components of product cost
In simple terms, product cost is the total amount spent to make your product ready for sale. Most product costs fall into three main categories:
- Direct materials (DM): These are the raw materials that become a physical part of your finished product. For example, if you’re making wooden chairs, the wood is a direct material. If you run a bakery, flour, sugar, and butter are direct materials. In other words, if you can point to it in the final product and say, “That’s part of what I’m selling,” it likely belongs here.
- Direct labor (DL): Your direct labor costs are the wages you pay workers who are directly involved in the manufacturing process. This can include the people who are assembling products, operating machinery, or baking the bread. However, this does not cover things like employee benefits or administrative salaries. In addition, it would not cover indirect costs like wages for marketing staff or customer service reps. It’s only the wages for people who are directly involved in creating the products.
- Manufacturing overhead (MOH): The manufacturing overhead costs include all other expenses related to production that aren’t direct materials or direct labor. This might include different products like glue or screws, indirect labor like a factory supervisor’s salary, and other factory costs like rent, utilities, and equipment maintenance. Some of these components are fixed costs (like monthly rent), while others are variable costs that can change from month to month or even day to day, like electricity usage.
The product cost formula
Now that you know the expenses involved in creating a product, you can figure out the total costs of production with a simple formula:
Total product cost = Direct materials + Direct labor + Manufacturing overhead.
And from there, you can figure out what each unit really costs you to produce with the following formula:
Unit product cost = Total product cost ÷ Total number of units produced.
Your unit product cost is what you need to set the selling price of a product. Let’s say it costs you $12 to produce one item. If you decide the final price is going to be $13, that won’t leave you with much profit, especially when you take into account payment processing fees, shipping, or discounts. But if your unit cost is lower than expected, you’ll have more flexibility to compete on price or increase your margin.
It’s also worth noting here that product costs are not the same as period costs. Period costs include expenses like marketing, office rent, and administrative salaries. They’re important, but they aren’t part of the manufacturing calculation. The total cost of production is only about what it takes to make the item itself.
How to calculate product cost step-by-step
Now let’s walk through a simple example so you can see how this might work for your online store. Let’s say you produce 500 custom journals in one batch. Here are the steps you can take to determine the total product cost:
Step 1: Calculate the total direct materials.
Imagine each journal requires $4 worth of paper, $2 for the cover, and $1 for binding materials. That’s $7 in direct materials per unit. For 500 journals, your total direct materials cost is: $7 × 500 = $3,500.
Step 2: Calculate total direct labor.
Now, let’s say it takes 10 minutes of labor to assemble each journal. That works out to roughly 83 labor hours for 500 units. If your total hourly cost is $20 per hour, your total direct labor cost would be: 83 × $20 = $1,660.
Step 3: Allocate manufacturing overhead.
Moving on to manufacturing overhead, let’s assume that your rent for the workspace, the cost of utilities, equipment depreciation, and indirect supplies add up to $2,000. If this batch represents half of your monthly production, you allocate $1,000 of manufacturing overhead to the 500 journals.
Step 4: Add everything together.
Direct materials: $3,500
Direct labor: $1,660
Manufacturing overhead: $1,000
Direct materials: $3,500
Direct labor: $1,660
Manufacturing overhead: $1,000
Total product cost = $6,160.
Step 5: Calculate the per-unit cost.
$6,160 ÷ 500 units = $12.32 per journal.
Finding the true cost of your product
The product cost formula covers the essentials for a finished product, but you’re also going to have additional costs beyond that. Your total expenses can also include waste and spoilage, equipment setup time before a production run, and small consumables used during production. And if you import products from China or other countries, you also need to consider landed costs like shipping, duties, insurance, and customs fees.
It’s also smart to think about capacity. If one product ties up your equipment or team for long stretches while delivering slim margins, that has an opportunity cost. You don’t need to make this complicated, but it is important to keep these numbers in mind so that you have a clear picture of how much each product truly costs your business.
Common product costing mistakes to avoid
One of the most common mistakes small business owners make is using outdated data. The direct material costs can change over time. In addition, wages can increase, and the cost of utilities can fluctuate. If you’re still working off last year’s numbers, your margins may not be what you think they are.
Another issue is misallocating manufacturing overhead. Spreading costs evenly across products without considering actual time or resource usage can throw off your unit costs. It’s also easy to mix up product costs with period costs, which can inflate your production numbers. Finally, don’t ignore variable costs, which rise as output increases.
Tools to make product cost calculation easier
There are plenty of tools out there that can help you track your costs and calculate the total product cost. Many business owners use Excel or Google Sheets to organize their balance sheets. You can even set them up to automatically total your direct materials, direct labor, and manufacturing overhead. As your operation grows, you may want accounting or inventory software that tracks things like material usage, labor hours, and overhead more accurately.
Final thoughts
As a business owner, it’s vital to know the true cost of your products so you can set prices that make sense for your business. When you combine that with market research, you can set your target margin and plan production accordingly. Plus, having those numbers clearly laid out in a spreadsheet can help you spot problems early, whether that’s high material costs or inefficient processes.
And when you’re reviewing your costs, sourcing also plays into that. If you’re exploring new suppliers or looking for better pricing on materials, Accio can be a useful tool to have in your corner. It’s an AI-powered sourcing platform that helps businesses compare supplier options, spot pricing trends, and uncover new opportunities in the market. Instead of jumping between spreadsheets and supplier lists, you can see your options in one place and make decisions with better information.
