Embarking on an interior design project — whether it’s a cozy bedroom refresh or a complete home makeover — is an exciting journey. But before you start picking paint swatches or flipping through furniture catalogs, there’s one crucial question:
“How much will this cost?”
At Interiyo, we believe in giving you the right tools to make confident, informed decisions. That’s why we created the Interior Design Project Cost Estimator — a smart, user-friendly tool to help you plan your budget more effectively.
🧮 How Our Calculator Works
Our calculator simplifies the process of estimating interior design costs.
Just provide a few details about your project, and you’ll get an instant, tailored estimate based on key factors that impact total expenses.
📋 What You’ll Need to Enter:
- Property Type: Apartment, house, office, or commercial space
- Size: Total area in square feet or meters
- Cost Per Unit: Your estimated cost per square foot/meter (based on service quality or market rate)
- Number of Rooms: Total rooms included in your design
- Desired Style: From minimalist to Gothic, your aesthetic preferences matter
🧠 Understanding the Calculation Formula
Our calculator uses a multi-factor logic to calculate your estimate.
➤ The Base: Cost Per Unit
This is your chosen cost per square foot or meter (e.g., $50 per sq. ft. or $538 per sq. m). It reflects your preferred quality level and local market conditions.
➤ The Multipliers: Why They Matter
Each of the following factors adjusts your base cost to reflect real-world complexity:
🏠 Property Type Multiplier
- Why: Design complexity varies by property (e.g., a commercial space vs. an apartment).
- Example:
- Apartment: 1.0
- Commercial Space: 1.8
🚪 Number of Rooms Multiplier
- Why: More rooms mean more detailed planning and materials.
- Example:
- 1–2 Rooms: 1.0
- 5+ Rooms: 1.25
🎨 Desired Style Multiplier
- Why: Styles like Gothic or Art Deco often require bespoke items or premium finishes.
- Example:
- Modern or Boho: 1.0
- Art Deco: 1.3
- Gothic: 1.4
🔢 The Final Formula
Estimated Cost = Property Size × Cost Per Unit × Property Type Multiplier × Number of Rooms Multiplier × Style Multiplier
This approach ensures your estimate is as accurate and personalized as possible.
