Key takeaways

• A direct cost is an expense you can trace to a specific product, service or job, such as materials or production wages
• Most direct costs are variable and rise with sales, though some, like salaried production staff, stay fixed
• Whether a cost is direct or indirect depends on what you’re costing, so choose one treatment and apply it every time
• Knowing your direct costs helps you set prices and track gross profit, and many count as allowable expenses for Irish tax

What is a direct cost?

A direct cost is an expense you can trace straight to a specific product, service or job you sell. Timber for a table, flour for a loaf and a plumber’s hours on a call-out are all direct costs.

For most small businesses, direct costs add up to your cost of sales, also known as cost of goods sold (COGS). Indirect costs, such as office rent or your accountant’s fees, sit separately because they keep the whole business running.

Examples of direct costs

Direct costs look different in every industry, but they always attach to what you sell. Depending on your business, they might include:

• stock you buy to resell, plus packaging and inbound freight, in a retail shop
• timber, fixings and subcontractors’ fees on a building or joinery job
• ingredients and kitchen staff wages in a café or restaurant
• staff hours and sales commissions tied to client work in a services business

Businesses often differ on whether workshop rent, warehousing or outbound delivery count as direct costs.

Pick a definition that suits how your business works, write it down and use it every month. Applying it the same way lets you compare margins across periods and gives your accountant a clear picture at year end.

Types of direct costs: materials and labour

Most direct costs fall into two groups: direct materials and direct labour. Together, they’re often called prime cost.

Direct materials are the physical inputs that become part of your product, such as flour in a loaf or steel in a gate. Direct labour is the pay for people who make the product or deliver the service, like a baker’s wages or an electrician’s hours on site.

Accounting standards count both towards what your stock is worth. Under IAS 2, the cost of inventory covers the purchase price of materials plus conversion costs, including direct labour. Anything else you can trace to one job, like a subcontractor’s fee, is often listed as a direct expense.

Are direct costs fixed or variable?

Most direct costs are variable, which means they rise and fall with how much you sell. Bake twice as many cakes and you’ll use roughly twice the flour and butter.

Some direct costs stay fixed over a period. A salaried production manager or a machine hired on a monthly contract costs the same whether you make 100 units or 500.

Knowing which direct costs flex helps you work out your marginal cost, the extra cost of making one more unit. That figure shows how low you can price a bulk order and still make money on it.

Direct costs vs indirect costs

Direct costs attach to a specific product, service or job, while indirect costs support the business as a whole. You’ll often hear indirect costs called overheads.

Here’s how the two compare.

• Direct costs usually change with sales volume; many indirect costs stay steady month to month
• Direct costs can be traced to a single unit or job; indirect costs are shared across everything you do
• Direct costs include materials, production wages and subcontractors; indirect costs include utilities, insurance, admin and marketing
• Direct costs determine your gross profit; indirect costs then come off gross profit on the way to net profit

Whether a cost is direct or indirect depends on what you’re costing. According to AccountingTools, the same cost can be direct for one cost object and indirect for another. A supervisor who runs one department, for example, is a direct cost of that department and an indirect cost of each product it makes.

Employees and premises often move between the two groups depending on your business. Choose the treatment that matches how you price and report, then stick with it.

How to calculate direct costs

You can total the direct costs for any product, job or batch in five steps.

1. Choose what you’re costing, such as one product line, a single job or a production batch
2. Add up the direct materials used, including packaging and freight to bring them in
3. Work out direct labour by multiplying the hours each person spent by their hourly pay rate
4. Add any other direct costs, such as subcontractor fees, equipment hired for the job or sales commissions
5. Total the figures, then divide by the number of units to get your direct cost per unit

Here’s a hypothetical example. A Galway joinery builds a batch of 10 oak dining tables and wants to know what each one costs to make. Its direct costs for the batch are:

• €3,000 for oak, including delivery to the workshop
• €500 for fixings, glue and finishes
• €3,000 for 120 hours of joiners’ time at €25 an hour
• €500 for a subcontractor to spray-finish the tables

That adds up to €7,000, or €700 per table. If the joinery sells each table for €1,200, it makes €500 gross profit per table before rent, insurance and other overheads.

Why direct costs matter for your business

Direct costs show what each sale really costs you. They feed into your prices, your profit, your cash planning and your tax return.

Setting prices that cover your costs

Your price should at least cover the direct cost of each item, which gives you a floor for every quote. Above that floor, add enough margin to pay for overheads and leave a profit.

Working out gross profit

Revenue minus cost of goods sold equals gross profit, as the Corporate Finance Institute explains. Dividing gross profit by revenue gives your gross profit margin, a quick check on whether your pricing and supplier costs are on track.

Planning cash for busy periods

More sales mean more direct costs, and you often pay suppliers and staff before customers pay you. A Cork bakery gearing up for Christmas, for example, needs cash for extra flour, butter and staff hours weeks before the takings arrive.

Building direct costs into a cash flow forecast shows how much you’ll need on hand before a seasonal peak or a big sales push.

Claiming direct costs as allowable expenses

In Ireland, many direct costs count as allowable expenses when you work out your taxable profit. The expenses you can claim, as Citizens Information sets out, include the purchase of goods for resale and employees’ pay.

The general test is that you incur the expense “wholly and exclusively” for your trade, as PwC’s Ireland tax summary notes. Capital items, such as a new van or machine, aren’t deductible as expenses, so ask your accountant how to handle them.

FAQs on direct costs

Here are quick answers to common questions about direct costs.

What’s another name for direct costs?

In your accounts, direct costs usually appear as cost of sales or cost of goods sold. Service businesses sometimes call them cost of services or cost of revenue.

Where do direct costs appear on a profit and loss statement?

They sit near the top, just below revenue, as cost of sales. Take them away from revenue to get gross profit, and overheads follow under operating expenses.

Do direct costs per unit change as you grow?

They can drop as you grow, because buying materials in bulk often earns supplier discounts. Your total direct costs still rise with volume, so keep an eye on both figures.

How can you lower your direct costs?

Start by comparing supplier quotes and checking how many labour hours each job really takes. Small savings per unit add up quickly across a busy year.

How often should you review your direct costs?

Review them whenever a supplier raises prices or wages change, and at least once a quarter. Regular reviews help you update prices while your margins are still healthy.
