6-month runway
$11,140 to $62,300
Check the breakdown before using this figure: if upfront costs already include a working-capital reserve, this formula counts additional runway on top of it. Listed monthly costs may be incomplete.
Startup cost plus six months of burn: a rough floor for how much cash to have in hand before you open, since most businesses aren’t profitable from day one.
How to lower these costs
Working capital reserve (3-6 months covering client deposit gaps and refund risk) is one of the largest one-time costs ($5,000 to $20,000). Look for used or leased equipment, a smaller initial order, or a phased buildout to shrink the upfront check.
Home office setup or small studio lease is one of the largest one-time costs ($500 to $8,000). Look for used or leased equipment, a smaller initial order, or a phased buildout to shrink the upfront check.
Home office setup or small studio lease runs $0 to $1,500/month. Negotiate the rate up front, shop multiple vendors, or delay this line item until revenue can cover it.
Launch marketing (local ads, Houzz/Instagram presence, networking events) runs $200 to $800/month. Negotiate the rate up front, shop multiple vendors, or delay this line item until revenue can cover it.

Frequently asked questions
How much does it cost to start an interior design business?
Starting an interior design business in the US typically costs $8,000-$35,000 all-in for a home-based solo practice, covering formation, insurance, software, a sample library, portfolio photography, launch marketing, and a working-capital reserve. A leased studio adds $12,000-$25,000 in first-year occupancy costs.
What is the cheapest way to start an interior design business?
The cheapest credible entry into interior design is a home-based, hourly-billing practice at roughly $5,000-$8,000: LLC filing, basic liability insurance, a SketchUp subscription, a portfolio website, and free client acquisition through Houzz and local realtor relationships. Skipping professional liability insurance to save money is the one cut that backfires — a single procurement dispute can exceed $10,000.
How do you finance an interior design startup?
Most interior design startups are self-funded from savings because the capital need is under $35,000 and banks rarely lend against unproven service businesses. Common alternatives are an SBA microloan (up to $50,000), a 0% introductory business credit card for software and samples, or keeping a part-time job through the first 12-18 months.
What are the ongoing monthly costs of an interior design business?
Ongoing monthly costs for a solo interior design practice run $400-$2,000: design and project-management software ($110-$500), insurance ($50-$200), marketing ($200-$800), sample replenishment, and vehicle costs for site visits. A studio lease adds $800-$1,500/mo on top.
What hidden costs do new interior designers miss?
The most-missed hidden costs in interior design are freight and receiving fees on client furniture orders (often 10-15% of order value), restocking fees of 15-25% on returned trade goods, unpaid proposal time that can run 10-20 hours per lost bid, and annual trade-program minimums some vendors require to keep discount access.
