Startup Cost Calculator for US Small Businesses (2026)

Methodology

This calculator estimates the total cash needed to launch a US small business by combining one-time launch costs with a working capital reserve sized to your chosen runway. All benchmark ranges reflect 2025-2026 US data drawn from the sources listed below the calculator.

How the benchmarks were built. For each of the seven business archetypes we cover, we compiled cost ranges from primary industry surveys, insurance data, government guidance, and 2025-2026 small business cost guides. Sources include the US Small Business Administration, Shopify's annual seller surveys, the US Chamber of Commerce Food Truck Nation Index, Insureon's published premium medians, the Federal Reserve Small Business Credit Survey, IBISWorld industry data, and multiple 2025-2026 industry guides. Where sources conflicted, we preserved the range rather than picking a single number, because startup costs vary genuinely by choice, location, and scale.

How to read the ranges. Every cost category shows a typical low-to-high range for your selected archetype. These ranges reflect the middle 60% of typical launches, not absolute floors and ceilings. It is possible to spend less than the low or more than the high, but the further you drift from the range, the more you should verify your assumptions.

What "typical" means for the funding score. The funding position score compares your total to the median startup cost for your archetype. "In line with typical launches" means your total is between 80% and 120% of the median. Below that range, you may be underfunded, which is the single most common reason viable businesses fail before becoming profitable. Above that range, you may be spending on items you don't actually need to prove the model.

Why we recommend generous runway reserves. Working capital reserve (months of monthly burn kept in the bank as a safety net) is the number most commonly underestimated by first-time founders. Our recommended runways range from six months for lean service businesses to twelve months for capital-intensive businesses like retail and food service. These numbers come from SBA guidance, Shopify Retail's published recommendations, and the pattern in the Federal Reserve Small Business Credit Survey showing that businesses under-funded on runway are disproportionately represented among the ones that don't survive their first two years.

A note on the One Big Beautiful Bill Act (July 2025). This law raised the Section 195 startup cost deduction cap from $5,000 to $50,000 in the year the business begins operations. This affects tax treatment, not cash outlay. If your qualifying startup costs are under $50,000, you can potentially deduct them in your first tax year rather than amortizing over 15 years. Consult a tax professional for your specific situation.

Limitations. This calculator is US-only. It does not include franchise fees, does not adjust for strongly seasonal businesses (like landscaping) beyond the runway lever, and treats state costs as three broad tiers rather than a full 50-state lookup. It also excludes variable costs that scale with revenue (payment processing, food COGS, inventory replenishment) from the monthly burn total, because those costs won't hit until the business is selling. Those variables are shown separately as awareness numbers. The output is a planning estimate suitable for taking to a lender or accountant. It is not a substitute for professional financial advice.

How much does it cost to start a US small business in 2026?

Starting a US small business costs anywhere from $500 to $750,000, depending on what kind of business you're launching. That range sounds unhelpful, but the numbers tighten fast once you specify the archetype. A home-based consultant launches for $500 to $15,000. A cleaning business runs $2,000 to $10,000 for a solo residential start. E-commerce sits between $1,000 for a dropshipper and $40,000 for a stocked Shopify store, with Shopify's own 2024 seller survey putting the average first-year total at about $40,000 across all their sellers. Brick-and-mortar retail costs $40,000 to $250,000, with industry averages landing around $39,000 to $48,000 depending on which 2025 survey you read (Shopify Retail cites $39,210; Lightspeed cites $48,000). Food service is the widest and most expensive category, spanning $50,000 for a used food truck to $750,000 for a full-service restaurant. The Federal Reserve's 2024 Small Business Credit Survey shows 50% of small employer firms applied for less than $100,000 in credit, which gives you a sense of where most real launches actually land.

What are the seven small business archetypes this calculator covers?

The calculator groups US small businesses into seven archetypes based on their cost profile. Home-based service covers consultants, freelancers, virtual assistants, and bookkeepers who deliver work from a home office. Field service covers cleaning, landscaping, HVAC, and handyman operations where the work happens at customer locations. E-commerce covers Shopify stores, WooCommerce sites, and marketplace sellers. Brick-and-mortar retail covers boutiques, gift shops, and specialty stores with a physical presence. Food service covers restaurants, food trucks, coffee shops, and bars. Professional services covers small firms (2-10 people) with an office: agencies, boutique law and accounting practices, design studios. Trade covers contracting, specialty trades, and small-scale manufacturing. These seven don't cover every possible business (franchises aren't a distinct archetype in version 0.1 because franchise fees vary too widely by brand), but they cover the vast majority of small businesses launched in the US each year. Pick the closest fit. If you're between two, pick the one with more physical overhead. It's better to over-budget than under-budget.

Which one-time costs surprise first-time founders?

Three categories consistently blow up first-time budgets. First, licenses and permits. The US Chamber of Commerce Food Truck Nation Index puts average first-year permits, licenses, and legal compliance costs at $28,276 for food trucks alone, and industry guides commonly cite $500 to $2,000 for restaurant health permits, $200 to $1,000 for contractor licenses, and $200 to $1,500 for state childcare licenses. Second, buildout. Retail buildout runs $147 per square foot on average across the US (Xero, 2025), $106 per square foot in the Midwest, and $216 per square foot in Northern California. A modest 1,000-square-foot boutique in an average US market starts at roughly $147,000 in buildout alone, before inventory or fixtures. Third, insurance pre-payment. Most insurance policies want the first year paid upfront or at least front-loaded, which puts a $500 to $2,000 spike in your first month that many founders plan as a monthly cost instead. A front-loaded first-year premium is one of the most common surprises new founders report. Ask your provider about payment terms before assuming monthly.

Which monthly costs get underestimated?

Payroll is the biggest one, and not for the obvious reason. Base salary is only about 70% to 80% of what an employee actually costs you. The SBA and NerdWallet both cite 1.25x to 1.40x base salary as the loaded cost multiplier, meaning a $50,000 employee actually costs the business $62,500 to $70,000 per year once payroll taxes, benefits, workers' compensation, and unemployment insurance are added. A team of three $50,000 employees runs $195,000 in loaded annual cost, not $150,000. The second underestimated monthly line is the software stack. What starts as $29 for Shopify Basic and $15 for email marketing quickly becomes ten to twenty subscriptions totaling $200 to $600 per month for a growing e-commerce store (Blackbelt Commerce, 2026). The third is insurance. Cleaning businesses budget $48 to $178 per month for basic insurance (Aspire, 2025), but that's before workers' compensation kicks in the moment you hire your first employee, which adds 0.75% to 2.74% of payroll depending on your state and industry.

Why does working capital reserve matter more than any other line item?

Working capital reserve is the cash you keep in the bank after opening to cover monthly costs while revenue ramps. It's not "extra" money. It's the money that keeps the doors open long enough to find your first customers and prove the model. Under-funded reserves are the single most common reason viable businesses fail before becoming profitable. The SBA recommends at least 3 to 6 months of operating expenses in reserve. Shopify Retail's guidance is 12 months for brick-and-mortar. The Federal Reserve's 2024 Small Business Credit Survey shows that businesses under-funded on runway are disproportionately represented among those that don't survive their first two years. Our recommended runways in this calculator range from 6 months for lean service businesses to 12 months for retail and food service. If you take one number from this page, take that one. Cutting your reserve to afford better equipment is a trade that consistently ends badly. Rent, insurance, and software will bill you every month whether or not customers have shown up yet.

How do state costs actually vary in the US?

State costs vary more than most guides admit, but the practical impact is smaller than the sticker prices suggest. LLC filing fees run $40 in Kentucky to $500 in Massachusetts, but California is the real outlier at $70 filing plus $800 annual minimum franchise tax, which makes it the most expensive LLC state to operate in by far. General business licenses run $50 to $400 per year in most cities. Workers' compensation rates vary by state and industry classification, ranging from 0.75% to 2.74% of payroll. Retail rents run $28.10 per square foot on average across US shopping centers, but prime urban locations in San Francisco, New York, and Los Angeles run 3 to 5 times that. This calculator uses three state tiers (low, mid, high) rather than a full 50-state lookup, which is a v0.1 tradeoff. It's directionally accurate for planning purposes but not a substitute for calling your specific state's Secretary of State office and city clerk to get exact numbers before you file. Do that before you write checks.

When should you use this calculator versus talking to an accountant?

Use this calculator when you're still deciding whether a business is even viable to launch given the capital you have or can raise. Use it when you're building a first-pass business plan and need a defensible ballpark to work from. Use it to check your gut assumptions against 2025-2026 industry data before you spend hours building a spreadsheet from scratch. Do not use it as your final loan application document. Do not use it as a substitute for tax advice or state-specific legal guidance. Once you have a specific location, a specific vendor list, and a specific team plan, walk through the numbers with an accountant who knows your industry. A good accountant will catch things this calculator can't, like specific state tax obligations, industry-specific deductions under the One Big Beautiful Bill Act's expanded Section 195 rules, and cash-flow timing issues around vendor payment terms and accounts receivable cycles. This calculator's job is to get you from "I have no idea" to "I have a defensible plan I can pressure-test with a professional." That's it.
