Key takeaways

• Categorise construction expenses by asking whether you can see or touch the result - if yes, it's a hard cost (labour, materials, equipment), if it's a service or administrative expense, it's a soft cost (permits, design fees, insurance).
• Budget for hard costs to represent 70-80% of your total project cost and soft costs 20-30%, but expect commercial projects to have higher soft cost percentages due to complex regulations and design requirements.
• Build contingency into your soft cost budget since these expenses are harder to predict and can continue throughout the entire project lifecycle, unlike hard costs which typically end when construction finishes.
• Use job costing software to track both cost types separately throughout your project, as this helps you spot budget overruns early and maintain healthy cash flow.

What are hard costs in construction?

Hard costs are expenses directly tied to the physical construction of a building. These include labour, raw materials, and equipment — anything you can see or touch on the job site. Hard costs typically make up the largest portion of your project budget, so tracking them accurately is essential for profitability.

Examples of hard costs

Hard costs fall into three main categories:

General contractor costs:

• labour and wages
• site supervision and overhead

Subcontractor costs:

• electrical work
• plumbing installation
• HVAC systems

Equipment and raw materials:

• structural materials (concrete, steel, timber)
• finish materials (flooring, paint, tiles)
• fixtures and appliances
• furnishings and landscaping

What are soft costs in construction?

Soft costs are expenses not directly tied to physical construction but essential for completing the project. These include professional services, permits, insurance, and financing — costs that typically occur before, during, and after the build itself. Soft costs are often harder to predict than hard costs, making them a common source of budget overruns.

Examples of soft costs

Common soft costs include:

Professional services:

• architect and engineering fees
• landscape and interior design
• site surveys and soil analysis

Administrative and legal:

• permits and planning applications
• legal fees and contracts
• insurance premiums

Financial costs:

• loan interest and financing fees
• project management
• accounting and auditing

What's the typical breakdown of hard vs soft costs?

Hard costs typically represent 70–80% of a construction project's total budget, with soft costs making up the remaining 20–30%. However, these ratios vary depending on project type, size, and complexity.

Typical breakdowns by project type:

• Residential builds: hard costs often reach 75–80%, with simpler permit and design work keeping soft costs lower
• Commercial projects: soft costs can climb to 25–35% because they must comply with more complex regulations and have more complex design and financing needs
• Renovations: soft costs may represent a higher percentage because design and permit work can be disproportionately complex relative to construction scope

Knowing these benchmarks helps you estimate projects more accurately and spot potential budget issues early. If your soft costs are significantly higher than industry averages, review where the money is going.

When do these costs occur?

Hard and soft costs follow different timelines throughout your project.

Hard costs occur during:

• pre-construction (material orders, equipment hire)
• active construction (labour, ongoing material purchases)
• project completion (final installations, finishing work)

Soft costs span the entire project lifecycle:

• Planning phase: architect fees, permits, legal reviews, site surveys
• Construction phase: insurance, project management, financing interest
• Post-construction: inspections, certifications, property marketing

Hard costs typically end when construction finishes. Soft costs can continue until the project is fully handed over or sold.

How do these costs affect a construction project's cash flow?

Hard and soft costs affect your cash flow differently. Understanding this helps with project planning and profitability.

Hard costs are generally easier to forecast because material and labour prices are relatively predictable. To estimate them accurately:

1. List all materials and equipment needed for the project.
2. Get comparison quotes from local suppliers.
3. Research labour rates for similar projects in your area.

Soft costs are trickier to predict because they're more variable and span the entire project timeline. To prepare for them:

1. Identify every potential soft cost category before starting.
2. Build contingency into your budget for unexpected expenses (such as legal challenges or permit delays).
3. Forecast a range of prices using best-case and worst-case scenarios.

You can record what you estimate in a cash flow forecast template to track spending throughout your project.

How to track costs during a construction project

Tracking hard and soft costs throughout your project helps you stay on budget, spot overruns early, and maintain healthy cash flow.

Use job costing software from Xero to monitor expenses by project and cost category. For more detailed job management, you can integrate your data between Workguru and Xero to streamline cost tracking and reporting.

With this knowledge, you can budget more accurately, manage cash flow confidently, and deliver profitable projects. Ready to simplify your construction accounting? Get one month free and transform how you manage construction finances.

FAQs on hard vs soft costs in construction

Answers to common questions about categorising and managing construction costs.

Are project management fees considered hard or soft costs?

Project management is typically classified as a soft cost because it's a professional service rather than a physical construction expense. The same applies when external consultants supervise the site.

Can soft costs be financed the same way as hard costs?

Some lenders include soft costs in construction loans, but terms vary. Soft costs are often harder to finance because they're less tangible than physical construction work. Check with your lender about what's covered before finalising your budget.

How do I categorise ambiguous expenses?

Ask whether the expense is directly tied to physical construction. If you can see or touch the result (materials, labour, equipment), it's a hard cost. If it's a service, fee, or administrative expense that supports the project without creating something physical, it's a soft cost.
