Interior Design Startup Costs – How Much You Need to Get Started

Understanding Interior Design Startup Costs

Some of the most common interior design startup costs include attorney fees, insurance, accounting software, and marketing expenses. You may also need to invest in furniture, equipment, and supplies for your office or studio. Depending on your location and business model, you may also need to pay for rent, utilities, and other overhead costs.

However, as we discussed in this article, there are multiple things you actually don’t need when getting started in design.

Regardless of your budget, before you start your interior design business, it’s important to create a detailed budget and plan for your startup costs. This will help you determine how much money you need to raise or save before you can launch your business. By understanding the costs involved and planning ahead, you can set yourself up for success and avoid financial surprises down the road.

Why are Startup Costs Important?

Startup costs are the expenses you incur to get your interior design business up and running. These costs can include everything from office space and equipment to marketing and advertising. It’s important to understand these costs upfront so that you can budget accordingly and avoid any surprises down the road.

Here are some of the startup costs you may need to consider:

  • Office Space: Depending on the size of your business, you may need to rent or purchase office space. Consider the location, size, and amenities of the space when making your decision.
  • Equipment and Supplies: You’ll need a computer, printer, phone, and other office supplies to run your business. You’ll also need design software and tools to create your designs.
  • Marketing and Advertising: You’ll need to promote your business to attract clients. This can include creating a website, business cards, and brochures. You may also need to advertise in local publications or online.
  • Insurance: You’ll need liability insurance to protect your business in case of accidents or lawsuits.
  • Professional Fees: You may need to hire a lawyer or accountant to help you set up your business and manage your finances.

Initial Business Costs

Starting an interior design business requires some initial costs. Here are the main costs you should expect to incur when starting an interior design business:

Business Registration

Before starting your interior design business, you need to register your business with the appropriate authorities. You can register your business as a sole proprietorship, partnership, LLC, or corporation. The registration fees vary depending on your country or state and business structure.

Legal Fees

It’s important to consult with a lawyer when starting your interior design business. A lawyer can help you with legal documents, contracts, and other legal matters. The legal fees vary depending on the lawyer and the services you need. Many organizations offer free legal advisory for startups, you should check it out before you invest in expensive lawyers.


Insurance is an essential expense for any business, including interior design. You need to protect your business and your clients from any potential risks. The insurance costs vary depending on the coverage and location.

Office Space

Some years ago, you needed a space to work and meet with clients. But since Covid, it’s becoming more of a norm to work from home or utilize coworking spaces. Renting an office space can be expensive, especially in prime locations. This is a cost that you can happily skip, at least until you have some clients and start building a team.

Equipment and Supplies

You need equipment and supplies to run your interior design business. This includes a computer, software, phone, printer, furniture, and other supplies. The equipment and supplies cost vary depending on the quality and quantity.

Marketing and Advertising Costs

When starting an interior design business, marketing and advertising are crucial to reaching potential clients. Here are some of the key areas to consider when budgeting for marketing and advertising costs.

Building a Website

Building a website is essential for any business, and an interior design website can showcase your portfolio and services. You can use website builders like Squarespace or WordPress to create a professional-looking website without having to hire a web developer. The cost of a domain name and hosting can range from $10 to $50 per year, and website design costs can vary depending on your needs.

However, you really want to give a professional first impression, so unless you are experienced in web design, I’d recommend bringing in an expert who can do it for you!

Marketing Strategy Leveraging Social Media

Developing a marketing strategy is important to target your ideal clients. Market research can help you identify your target audience, understand their needs, and tailor your marketing efforts accordingly.

You can use social media platforms like Instagram and Pinterest to showcase your work and connect with potential clients.


Advertising can be an effective way to reach potential clients and increase your brand awareness. You can choose between print advertising in local magazines or newspapers, or online advertising on platforms like Google Ads or Facebook Ads. The cost of advertising can vary depending on the platform and your budget.

However – when starting out, I’d not recommend choosing print advertising but learning how to use digital platforms to build brand awareness and generate leads!

Professional Development Costs

When starting an interior design business, it’s important to consider the costs of professional development. These expenses can help you improve your skills, stay up-to-date on industry trends, and build your reputation in the field. Here are some of the professional development costs you should consider:

Education and Certification

If you’re just starting out in interior design, you may need to invest in education and certification to build your credentials. You can take courses or pursue a degree in interior design, which can range from a few thousand dollars to tens of thousands of dollars depending on the program and institution.

Certification programs, such as those offered by the American Society of Interior Designers (ASID), can also help you demonstrate your expertise to clients and employers.

Continuing Education

Even after you’ve completed your education and obtained certification, it’s important to continue learning and developing your skills. Continuing education courses will help you stay up-to-date on the latest trends, techniques, and technologies in interior design.

These courses can range from a few hundred dollars to several thousand dollars depending on the provider and the length of the course.

Professional Memberships

Joining a professional organization, such as the ASID or the American Institute of Architects, or SBID in the UK, can help you network with other professionals in the field and gain access to resources and events that can help you grow your business. Membership fees can range from a few hundred dollars to several thousand dollars depending on the organization and your level of membership.

Overall, investing in professional development can be a significant expense for interior designers and architects. However, it can also be a worthwhile investment in your career and your business. By improving your skills, building your credentials, and networking with other professionals, you can position yourself for success in the competitive field of interior design.

Project Costs

When starting an interior design business, one of the most important factors to consider is the cost of each project. Project costs can vary greatly depending on the scope of work, materials and supplies, contractors and vendors, furniture and accessories, and other factors. Here are some things to keep in mind when estimating project costs.

Materials and Supplies

Materials and supplies are a major cost factor in any interior design project. As an interior designer, you will need to purchase a variety of materials and supplies, such as fabrics, paint, wallpaper, flooring, and lighting. It is important to budget for these costs and to shop around for the best deals.

To save money on materials and supplies, consider purchasing in bulk or using remnant pieces. You can also negotiate with suppliers for better prices or look for sales and discounts. Keep in mind that high-quality materials and supplies will often result in a better end product, so it may be worth the investment.

Contractors and Vendors

When working on larger projects, you may need to hire contractors and vendors to help with installation, construction, or other tasks. These costs can add up quickly, so it is important to budget accordingly.

To save money on contractors and vendors, consider working with local professionals who offer competitive rates. You can also negotiate prices and ask for referrals from other interior designers or contractors.

Ongoing Business Expenses

As you establish your interior design business, you’ll need to factor in ongoing expenses to keep your business running smoothly. Here are some of the key ongoing expenses you’ll need to consider:

Accounting and Taxes

As your business grows, you’ll need to keep track of your finances carefully. This includes tracking your income and expenses, managing your tax obligations, and ensuring that you’re keeping accurate financial records.

You may want to consider hiring an accountant to help you manage your finances, or investing in accounting software to help you stay organized.

Liability Insurance

As an interior designer, you’ll be working with clients in their homes or businesses, and you’ll need to protect yourself from liability in case of accidents or damages. Liability insurance can help cover the costs of any damages or injuries that occur while you’re working on a project.

Software Expenses

To run your interior design business efficiently, you’ll need to invest in software to help you manage your projects and finances. This may include project management software, accounting software, and design software. Be sure to research your options carefully and choose software that meets your needs and budget.

It’s important to keep in mind that ongoing expenses will vary depending on your business model and the types of services you offer. For example, if you charge a project percentage fee, your ongoing expenses may be lower than if you charge a retainer or cost plus fee. Similarly, if you charge a cost per square foot or meter, your ongoing expenses may be higher than if you charge a flat fee.

Overall, it’s important to carefully consider your ongoing expenses as you establish your interior design business. By planning ahead and budgeting for these expenses, you can help ensure that your business is successful and profitable in the long run.

Interior Design Startup Costs – Sum Up

Starting an interior design business can be an exciting and rewarding venture. However, it is important to be aware of the startup costs and ongoing expenses that come with it. By understanding and planning for these costs, you can set your business up for success.

However, it’s important to thoroughly research and understand the terms and conditions of these options before accepting them.

Obtaining a certificate or passing an exam can also be beneficial in establishing your credibility and expertise in the field. However, it’s important to weigh the cost of these programs against the potential benefits they may provide.
