Starting a Trades Business: Startup Costs and Break-Even Calculator

Startup Costs by Trade

Plumbing Business ($12,000–$30,000)

Electrical Business ($10,000–$25,000)

HVAC Business ($25,000–$50,000+)

General Contracting ($20,000–$50,000)

The Licensing Maze

Licensing requirements vary dramatically by state and municipality. According to data from the Bureau of Labor Statistics, nearly all states require electricians and plumbers to hold active licenses, while general contractor licensing requirements vary.

What you typically need:

1. Trade-specific license — Pass an exam (journeyman or master level)
2. Business license — Register with your city/county
3. Contractor's bond — $5,000–$25,000 (you pay a premium, not the full amount)
4. Insurance — General liability ($1M minimum), workers' comp (if hiring), commercial auto
5. LLC or S-Corp — Protects personal assets; S-Corp can save on self-employment taxes

There is no national fee schedule for any of this, and the numbers move every legislative session — get your figures from your own state licensing board and your city clerk rather than from any article. Two costs people routinely leave out of the startup budget: the exam prep and the exam itself (often $300–$700 all in, and a retake if the first attempt fails), and the continuing education hours required to keep the license, which recur every renewal cycle for as long as you hold it.

Setting Your Hourly Rate

The biggest mistake new trades business owners make is pricing too low. Your rate needs to cover:

• Your target salary
• Taxes (self-employment tax is 15.3% on top of income tax)
• Insurance and licensing
• Vehicle and fuel costs
• Tool replacement and maintenance
• Unbillable time (estimates, travel, admin, marketing)
• Profit margin for growth

The math: If you want to earn $80,000/year and you can bill 1,500 hours (about 30 billable hours/week), your base rate needs to be $53/hour just for salary. Add 30–40% for overhead and taxes, and your minimum charge-out rate should be $70–$75/hour. Most experienced tradespeople charge $85–$150/hour depending on trade and market.

Set the rate from your own target income and real billable hours with the contractor hourly rate calculator — the unbillable hours are the input people guess at, and guessing low there is what produces a rate that looks profitable and isn't.

How Long Until You Break Even?

Your break-even timeline depends on three factors:

1. Startup costs: How much you invested upfront
2. Monthly overhead: Insurance, vehicle, phone, software, marketing
3. Revenue ramp-up: How quickly you fill your schedule

Realistic scenario: $20,000 startup costs, $2,000/month overhead, billing $75/hour at 25 hours/week = $7,500/month gross. After overhead: $5,500/month profit. Break-even on startup costs: ~4 months.

Conservative scenario: Same costs, but only 15 billable hours/week for the first 3 months while building your client base. Break-even: 7–10 months.

The number both scenarios leave out is working capital. Startup costs buy the van and the tools; they do not float the job. On a $12,000 bathroom remodel you may buy $4,000 of materials in week one and invoice on completion in week four — and if the customer is a general contractor or a property manager, net-30 terms mean the money lands in week eight. That is two months of materials, fuel and your own wages funded out of your pocket. Budget one to two months of operating costs on top of the startup table for your trade, and treat a line of credit as a cash-flow tool rather than a startup expense. Undercapitalization, not lack of work, is what closes most first-year trades businesses.

Getting Your First Customers

The trades have a massive advantage over most businesses: demand is constant and local. People always need plumbers, electricians, and HVAC techs. Your challenge isn't creating demand — it's capturing it.

Week 1–4: Foundation

• Google Business Profile (free, critical for local search)
• Simple website with your services, service area, and phone number
• Business cards and vehicle lettering/wrap

Month 1–3: Network

• Introduce yourself to local real estate agents (they always need reliable contractors)
• Connect with property managers (recurring maintenance contracts)
• Join your local BNI or trade association chapter
• Post in neighborhood Facebook groups and Nextdoor

Month 3–6: Reviews and Referrals

• Ask every satisfied customer for a Google review
• Offer a referral bonus ($25–$50 per new customer referred)
• Consider Angi, Thumbtack, or HomeAdvisor for lead generation (be selective — track your cost per acquisition)

Month 6+: Scale

• SEO and content marketing for your website
• Consider hiring your first helper/apprentice
• Build maintenance contract revenue for steady monthly income

Solo vs Hiring: When to Scale

Stay solo if you want to keep things simple and maximize your hourly take-home pay. A solo plumber billing 30 hours/week at $100/hour can clear $120,000–$150,000/year with modest overhead.

Consider hiring when:

• You're consistently turning away work
• You want to grow revenue beyond what one person can generate
• You're ready to handle payroll, workers' comp, and management responsibilities

Each employee should generate 2–3x their cost in revenue. If you pay a helper $25/hour and bill their time at $65/hour, they're profitable from day one.

Sole Proprietor vs S-Corp: The Actual Numbers

"Form an S-Corp and save on taxes" is the most repeated advice in the trades and the least often quantified. Here is the arithmetic at $100,000 of net profit.

A sole proprietor pays self-employment tax of 15.3% on 92.35% of net profit — the 92.35% adjustment is what stops you paying the employer half on itself. An S-Corp shareholder-employee splits the same profit into a salary, which carries the full 15.3% in payroll tax, and a distribution, which carries none.

Three things decide whether that holds for you:

• The salary has to be reasonable. It is the one number the IRS actually audits in S-Corps, and "reasonable" means what you would have to pay someone else to do your job — for a licensed tradesperson doing the work as well as running the business, a token $20,000 salary on $100,000 of profit will not survive scrutiny.
• Profit level matters more than revenue. Below roughly $50,000 of net profit, the payroll and accounting overhead eats most of the saving. That is where the usual $40,000–$50,000 threshold comes from.
• The 2026 Social Security wage base is $184,500. Above that, only the 2.9% Medicare portion applies to further earnings, so the S-Corp saving on the Social Security half stops growing — which is why very high-profit years save proportionally less than people expect.

An S-Corp salary also reduces your qualified business income, and therefore the §199A deduction, which claws back part of the payroll-tax saving. Run your own profit figure through the self-employment tax calculator before paying anyone to file the election.

What These Numbers Don't Cover

The tables above are the cost of starting. Four things routinely turn a profitable-looking first year into a loss:

• Workers' compensation, the moment you hire. Premiums are quoted per $100 of payroll and vary enormously by trade classification and state — roofing and HVAC rate far above electrical. Get a quote before you make an offer, not after.
• Sales and use tax on materials. Whether you charge tax on materials, labour, or the whole invoice is a state-by-state rule, and getting it wrong on a year of invoices is an expensive thing to discover in an audit.
• Retainage on commercial work. General contractors commonly hold back 5–10% of each invoice until the whole project closes out, which can be months after your part is finished. On $200,000 of commercial work that is $10,000–$20,000 you have earned and cannot spend.
• Seasonality. HVAC lives on two peaks and two troughs a year; new-construction electrical follows the housing cycle. Your break-even calculation should use your slow quarter, not your average one.

FAQ

Do I need an LLC to start a trades business?

You don't legally need one, but you absolutely should form one. An LLC separates your personal assets from business liabilities. If someone sues your business, your house and savings are protected. Filing costs $50–$500 depending on your state.

How much should I save before leaving my W-2 job?

Save 6 months of personal living expenses plus your full startup costs. Start building your client base on weekends and evenings while still employed. Many successful trades business owners transition gradually rather than quitting cold.

Should I form an S-Corp?

Once you're consistently profiting over $40,000–$50,000/year, an S-Corp election starts to pay for itself. The table under "Sole Proprietor vs S-Corp" above runs it at $100,000 of net profit: about $4,950 of payroll tax saved, less $1,200–$2,500 a year of payroll service and extra return preparation. Below that profit level the overhead usually eats the saving, and at any level the salary you pay yourself has to be defensible as the market rate for your own labour.

What's the most profitable trade to start?

HVAC tends to have the highest revenue potential due to equipment costs and seasonal urgency. Plumbing has the steadiest demand. Electrical work has lower startup costs. The "best" trade is the one you're skilled at and enjoy — expertise drives profitability more than trade selection.

Run Your Own Numbers

Put your fixed monthly overhead, your charge-out rate and your materials cost into the break-even calculator to find the billable hours per month that actually cover your costs. That figure — not the startup total — is the one to check your schedule against every week. And if you are financing the van and the first tool package rather than paying cash, the SBA loan calculator prices the monthly payment and tests it against the cash the business is realistically producing in its first year.
