Business Startup Cost Calculator — United States 2026
What starting the business actually needs in the bank: one-time setup, the runway to carry monthly costs until it turns a profit, a safety buffer, and a contingency on top — with the split across setup, inventory, equipment, build-out and launch marketing.
Total capital is one-time costs plus runway plus buffer, then a contingency percentage on that subtotal.
| One-time | $15,000.00 |
|---|---|
| Runway | $96,000.00 |
| Buffer | $24,000.00 |
| Contingency | $13,500.00 |
| General setup | $15,000.00 |

How the startup costs works
Total capital is one-time costs plus runway plus buffer, then a contingency percentage on that subtotal. Runway is monthly operating costs times the months you expect to take to reach profitability — the number most first-time owners get wrong, because it is the money that keeps the doors open while revenue is still building, not the money that opens them. The buffer is extra months of the same costs held back for the thing you have not thought of; three months is the usual minimum. The contingency covers cost overruns on the one-time items, where 10% is optimistic and 20% is realistic for anything involving a build-out. On registration: an LLC is formed with a state and the fee varies widely by state, an EIN from the IRS is free, sales tax registration follows wherever you have nexus rather than where you are formed, and an SBA 7(a) loan — a bank loan the Small Business Administration guarantees — is the usual first outside money, which is why lenders will want to see this capital figure and the assumptions under it.
Formula: Capital = one-time + (monthly × months to profit) + (monthly × buffer months), then × (1 + contingency)
How startup capital is calculated
The formula
Total startup capital = One-time setup costs + Monthly runway + Safety buffer + Contingency
One-time setup costs
Everything you pay once to get the business operational: business registration, fitout, equipment, website, branding, initial legal fees, insurance deposits, franchise fees, and initial stock. These are not recurring — you pay them once at the start.
Runway
Monthly operating costs × months until profitability. This is the cash you need to cover rent, wages, utilities, subscriptions, and COGS while the business builds revenue. Most businesses take 6–18 months to reach cash-flow positive. If you reach profitability faster, leftover runway becomes working capital.
Safety buffer
Typically 3 months of operating costs held in reserve. This covers unexpected expenses, seasonal dips, or slower-than-expected revenue growth. Without a buffer, any unexpected cost can force the business to close even if it is otherwise viable.
Contingency
A 10–20% loading on the total for items you did not anticipate. Startup costs almost always exceed initial estimates. Research consistently shows first-time business owners underestimate costs by 20–30%. A 10% contingency is conservative — 20% is more realistic for complex setups.
Startup costs by business typeStartup cost ranges by business type — United States 2026
| Business type | Setup costs | Monthly costs | Months to profit | Typical total capital |
|---|---|---|---|---|
| Online/digital service | $2k–$15k | $2k–$8k | 3–9 months | $15k–$75k |
| Home-based trade/service | $5k–$30k | $3k–$10k | 3–12 months | $25k–$100k |
| Office-based professional | $20k–$60k | $8k–$20k | 6–18 months | $100k–$300k |
| Retail shop | $50k–$150k | $15k–$40k | 12–24 months | $200k–$600k |
| Cafe (small) | $80k–$200k | $20k–$50k | 12–24 months | $300k–$700k |
| Restaurant | $150k–$400k | $30k–$80k | 12–36 months | $500k–$1.5M |
| Manufacturing | $100k–$500k | $20k–$100k | 12–36 months | $400k–$2M |
Why costs vary so much
The three biggest drivers are: (1) physical premises — rent, fitout, and security bond; (2) staff — wages are usually the largest ongoing cost; and (3) stock/inventory — product businesses need to purchase before they can sell. Service businesses that can be run from home with no staff have the lowest startup costs.
Business registration costs in United States 2026
| Registration | Cost | Where | Notes |
|---|---|---|---|
| EIN (Employer Identification Number) | Free | IRS (irs.gov) | Needed to hire staff, open a business bank account, or file as an LLC/corporation |
| DBA / assumed name | $10–$100 one-time | State or county clerk | Required if you trade under a name other than your own or your LLC's |
| LLC formation | $50–$500 | State Secretary of State | One-off filing; annual report / franchise fee varies by state |
| Sales-tax permit | Free in most states | State dept of revenue | Needed once you have nexus — often $100k of in-state sales or a physical presence |
| Domain name (.com) | $15–$30/year | Various registrars | No special ID needed to register a .com |
| Trademark registration | $350/class | USPTO (uspto.gov) | Recommended if brand is central to business |
Sole proprietorship vs LLC — cost implications
A sole proprietorship is free and simple to run but gives no personal liability protection — you and the business are the same legal person. An LLC costs $50–$500 to form (varies by state) plus accountant fees and provides limited liability, so your personal assets are shielded if the business fails. For any business with meaningful risk or assets, an LLC (or S-/C-corporation) is generally recommended despite the higher setup cost.
How to fund your US startup
Personal savings (bootstrapping)
The most common funding source for US small business startups. No debt, no dilution, no reporting requirements. The downside: limits how fast you can grow and requires sufficient personal savings. Most financial advisers recommend having 6–12 months of personal living expenses saved separately from business capital before quitting employment.
Business bank loans
Most banks require 1–2 years of trading history before lending to a business, making loans difficult for genuine startups. Exceptions: equipment finance (asset-secured from day one), SBA-backed loans such as 7(a), 504, and microloans (the government guarantee reduces bank risk), and home-equity lending (if you own property). Fintech lenders (OnDeck, Fundbox, Bluevine) are more startup-friendly but charge higher rates.
Government grants
Competitive and targeted but worth exploring. Key sources: grants.gov for federal grants; the SBIR/STTR federal R&D grant programs for innovative small businesses; and your state's economic-development grant portal. Separately, the federal R&D tax credit lets a qualified startup (under $5M in gross receipts, less than five years old) offset up to $500,000 of payroll tax a year. Grants are not loans — you do not repay them.
Friends, family, and angels
Common for early-stage startups. Always document the arrangement in writing — whether it is a loan or equity investment. Angel investors provide capital in exchange for equity (ownership) — typically 5–25% for early-stage startups. You can find angels through networks and platforms such as AngelList, Tech Coast Angels, Golden Seeds, and Gust.
FAQFrequently asked Frequently asked questions
How much does it cost to start a business in the United States?
Startup costs vary enormously by type. A home-based online service business can be started for $5,000–$20,000. A retail shop typically requires $100,000–$400,000. A cafe or restaurant often needs $200,000–$700,000. The key costs are: one-time setup (fitout, equipment, registration), operational runway until profitability, and a safety buffer of 3–6 months of operating expenses.
How long does it take for a small business to become profitable in the United States?
Most US small businesses take 12–24 months to reach profitability. Service businesses with low overhead can achieve profitability in 3–9 months. Retail, hospitality, and businesses requiring heavy upfront investment typically take 18–36 months. Plan your funding runway generously — it almost always takes longer than expected.
Do I need a company or can I operate as a sole proprietor?
Operating as a sole proprietorship is free and simple — you report business income on your personal tax return (Schedule C). An LLC costs $50–$500 to form (varies by state) plus ongoing compliance costs ($1,500–$3,000/year with an accountant), but provides limited liability protection. For businesses with physical risk, employees, significant assets, or clients who require company contracts, forming an LLC is usually worth the extra cost.
What is a realistic startup budget for a cafe in the United States?
A small cafe typically requires $150,000–$400,000 in total startup capital. Breakdown: commercial kitchen equipment $60,000–$150,000; build-out and furniture $50,000–$120,000; security deposit and first month's rent $20,000–$60,000; initial stock and smallwares $5,000–$15,000; licenses and permits $2,000–$8,000; staff training and pre-opening marketing $5,000–$20,000; plus 6–12 months of operating costs as runway and buffer.

How to fund your US startup Savings, loans, grants, investors

|---|---|
| Business bank loan | Secured: 7–11% · Unsecured: 12–25%+ |
| Family and friends | Common — but document everything |
| Government grants | grants.gov — highly competitive |
| Angel investors | Equity for capital — give up ownership |
| Accelerators (Y Combinator, Techstars) | Equity + mentoring + small capital |
- SBIR/STTR grants Federal R&D grants for innovative small businesses
- R&D tax credit Qualified startups can offset up to $500k of payroll tax
- SBA loan guarantees Government-backed lower-rate loans (7(a), 504, microloans)
- Equity crowdfunding Via Reg CF platforms (Wefunder, StartEngine, Republic)
- Revenue-based finance Repay as % of monthly revenue
