Running an architecture or design firm is not just about creativity. It is also about making smart financial decisions to keep your practice sustainable. One of the most important steps is knowing your operating costs, which serve as the foundation for pricing your services fairly and ensuring profitability.

Operating costs refer to all expenses needed to keep your firm running. For architecture, interior design, landscape, or allied arts businesses, these include salaries, rent, utilities, marketing, and costs related to project delivery.

1. List Your Fixed Costs

These are the expenses you pay monthly or annually regardless of how many clients you have. For architecture and design firms in the Philippines, fixed costs usually include:

• Office Rent or Mortgage – Monthly payments for your studio or office space.
• Salaries of Core Staff – Administrative assistants, accountants, or full-time junior architects.
• Utilities and Subscriptions – Electricity, water, internet, phone lines, AutoCAD/SketchUp/Adobe licenses, cloud storage.
• Professional Fees and Insurance – Annual PRC license renewal, professional indemnity insurance, business permits, and BIR requirements.

2. Identify Variable Costs

Variable costs change depending on the number and size of projects you handle. These include:

• Project-Specific Expenses – Printing, plotting, models, and renderings.
• Consultant Fees – Payments to structural, MEPF, or specialist consultants.
• Travel and Site Visits – Transportation, fuel, and accommodation for out-of-town projects.
• Marketing and Business Development – Paid ads, social media promotions, or participation in design expos and competitions.

3. Include Semi-Variable Costs

Some costs may be fixed but can still fluctuate depending on workload, such as:

• Part-Time or Project-Based Staff – Draftsmen, renderers, or interns paid per project.
• Utility Bills – Electricity may increase if your team works overtime for deadlines.

4. Compute Your Total Operating Cost

Use this formula:

Operating Cost = Fixed Costs + Variable Costs + Semi-Variable Costs

Example (per month for a small firm in Davao or Cebu):

• Fixed Costs = ₱120,000 (office rent, admin salaries, software, permits)
• Variable Costs = ₱40,000 (printing, travel, consultant fees)
• Semi-Variable Costs = ₱15,000 (overtime utilities, project-based staff)

Total Operating Cost = ₱175,000 per month

5. Determine Your Cost Per Project

To know the minimum fee you should charge, divide your total operating costs by your average number of projects per month or total billable hours.

For example, if your firm handles 3 projects per month, your operating cost per project is around ₱58,333.
You should then add your desired profit margin (usually 20% to 40%) on top of this amount.

6. Factor in Local Business Requirements

Architecture and allied arts firms in the Philippines must also account for:

• BIR taxes and filings
• PhilHealth, SSS, and Pag-IBIG contributions for employees
• Annual business permit renewal fees

These government-mandated costs should be included in your fixed operating expenses.

7. Review Regularly

Prices of rent, utilities, and software licenses go up. It is best to review your operating costs quarterly or at least yearly to ensure your fees remain fair and sustainable.

Why This Matters for Architects and Designers

Knowing your operating cost prevents undercharging, which is a common problem for regional firms in the Philippines. It helps you:
✅ Price your design services realistically.
✅ Plan for growth (new hires, bigger office, upgraded software).
✅ Avoid financial stress while focusing on quality design.
