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
Used cargo van or service truck (upfitted with shelving/racks) is one of the largest one-time costs ($12,000 to $38,000). Look for used or leased equipment, a smaller initial order, or a phased buildout to shrink the upfront check.

Frequently asked questions
How much does it cost to start a plumbing business?
Starting a one-van plumbing business in the US typically costs $35,000-$80,000 all-in for a founder who already holds a license: $12,000-$38,000 for an upfitted used van, $7,500-$27,000 for tools, drain equipment and an inspection camera, $2,000-$6,000 in initial truck stock, plus licensing, insurance, software and a working-capital reserve. Operators who skip the sewer camera and jetter initially and rent them per job can land closer to $30,000.
What is the cheapest way to start a plumbing business?
The cheapest legitimate entry is a licensed plumber operating solo from home with a used van ($12,000-$18,000), hand tools only ($4,000-$6,000), a $200-$500 Google Business Profile-led marketing push and rented drain/jetting equipment per job — bringing launch cost to roughly $25,000-$35,000. The one cost that cannot be skipped is the license itself: operating unlicensed in states like California, Texas or Florida risks fines of $5,000+ per violation and voids insurance.
Can you finance a plumbing business startup?
Yes — the most common financing stack for a plumbing startup is a commercial vehicle loan or lease for the van (typically 10-20% down), an SBA Microloan or 7(a) loan of $25,000-$50,000 for tools and working capital, and equipment financing from vendors like Crest Capital or Balboa Capital for high-ticket items such as hydro-jetters and inspection cameras. Because a licensed plumber's revenue is relatively predictable, lenders generally view this category more favorably than restaurants or retail.
What are the ongoing monthly costs of running a plumbing business?
Ongoing monthly costs for a one-van plumbing operation typically run $1,500-$4,500: commercial auto insurance ($150-$400), liability insurance ($100-$300), field service software like Housecall Pro or Jobber ($65-$400), truck-stock replenishment ($300-$1,200), fuel and vehicle maintenance ($400-$800), and marketing spend of $500-$2,500 where Google Local Service Ads leads often cost $25-$75 each. Payroll is the variable that changes everything — the first employed journeyman adds roughly $6,000-$9,000 per month fully loaded.
What hidden costs do new plumbing business owners miss?
The hidden costs new plumbing owners most often miss are callback and warranty rework (budget 3-5% of revenue for free return visits), tool and inventory shrinkage from unmonitored truck stock, workers' compensation premiums which for plumbing commonly run $8-$15 per $100 of payroll given the trade's injury rates, and license renewal, continuing education and bond fees that recur annually. Owners also routinely underprice disposal fees for water heaters and old fixtures, which municipal transfer stations charge $20-$75 per load.
