6-month runway
Startup cost plus six months of burn: a rough floor for how much cash to have in hand before you open, since most businesses are not profitable from day one.
$44,080 to $209,100
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.
How to lower these costs
Working capital reserve (6 months overhead — the #1 survival factor)
Working capital reserve (6 months overhead — the #1 survival factor) is one of the largest one-time costs ($15,000 to $60,000). Look for used or leased equipment, a smaller initial order, or a phased buildout to shrink the upfront check.
Work truck purchase or down payment (used pickup + tool storage)
Work truck purchase or down payment (used pickup + tool storage) is one of the largest one-time costs ($8,000 to $45,000). Look for used or leased equipment, a smaller initial order, or a phased buildout to shrink the upfront check.
Workers' compensation insurance (deposit + payroll-based premiums), monthly
Workers' compensation insurance (deposit + payroll-based premiums) runs $300 to $2,000/month. Negotiate the rate up front, shop multiple vendors, or delay this line item until revenue can cover it.
Marketing launch (branded truck wrap, website, Google Local Service Ads budget), monthly
Marketing launch (branded truck wrap, website, Google Local Service Ads budget) runs $300 to $1,500/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 a general contractor business?
Starting a general contractor business in the US realistically costs $35,000-$150,000 all-in: $3,000-$8,000 for licensing, bonding, and initial insurance; $11,000-$60,000 for a truck and tools; $3,000-$10,000 for software and marketing; and critically $20,000-$60,000 in working capital to float materials and payroll between client payments. The working capital, not the equipment, is where most new GCs under-budget.
What is the cheapest way to start a general contractor business?
The cheapest credible entry is starting as a project-manager-only GC from a home office with a used truck, leased or owned hand tools, and fully subcontracted labor — cutting startup costs to roughly $25,000-$40,000, mostly insurance, licensing, and working capital. You trade margin (no self-performed work markup) for survival odds, then add crews once cash flow stabilizes.
Can you finance a general contractor startup?
Yes — common financing routes for a general contractor startup include SBA 7(a) loans (typically requiring 10-20% down and a track record), equipment financing for trucks and tools, and business lines of credit sized to cover the receivables gap. Material supplier trade credit (Net-30 accounts at lumberyards) is effectively free short-term financing and should be established in the first 90 days.
What are the ongoing monthly costs of running a general contractor business?
A solo GC's fixed monthly overhead typically runs $1,500-$5,000: general liability and workers' comp ($400-$2,300), truck payment and fuel ($500-$1,500), software ($200-$900), and marketing ($300-$1,500). Variable job costs — labor, materials, permits — are passed through with markup but must be funded before client draws arrive.
What hidden costs do new general contractors miss?
The hidden costs that sink new GCs are: retainage (5-10% of every contract held until closeout), warranty callback labor on finished jobs, estimating time on bids you lose (win rates of 20-30% mean 3-4 unpaid estimates per win), insurance audit true-ups when payroll exceeds projections, and license renewal/continuing-education fees that vary by state.
