When to hire your first employee as a solo trade contractor

Running solo and booked three weeks out sounds like the dream — until it's Thursday and you're turning down a good job because there's no room in the calendar until next month. The question of when to hire your first employee is one of the hardest calls in a solo contractor's business life. Hire too early and you're paying someone out of savings while you scramble to keep their schedule full. Hire too late and your best customers get tired of waiting and call someone else. This post gives you the workload signals, the real cost breakdown, and the break-even math you need to make this decision with your eyes open.

Three signs you're ready to hire your first employee

A busy season and a business that needs more capacity aren't the same thing. These three signals tell them apart:

1. You're turning down profitable work at least two weeks a month.

Turning down one job in a crunch week happens to every solo operator. But if you're consistently declining work you'd otherwise take — not because the job is a bad fit, but because you genuinely can't get there — that's a capacity problem. Keep a log for 60 days. Every time you pass on a job for capacity reasons, note the type and approximate dollar value. If the total across those 60 days exceeds a month's overhead, you're already losing more than a hire would cost.

2. Your close rate is strong but revenue has plateaued.

A healthy quote close rate for solo trade contractors runs roughly 40–60% on service calls. If you're winning most of what you send and revenue is still flat, you've hit a ceiling on what one person can bill. More leads won't fix a ceiling; more hours will.

3. You're clearing $80K–$100K or more in solo revenue.

At that level, your personal hourly rate is high enough that callbacks, drive time, supply runs, and admin are costing you real money in foregone billable hours. That's work a helper or junior tech can absorb while you stay on the higher-value calls. It's not a hard floor — your trade, your margin structure, and your market all shift the number — but it's a reasonable place to start running the math.

None of these signals alone is a reason to hire. All three together means it's time to pull out a calculator.

What hiring an employee actually costs you per hour

Most solo contractors look at a wage number — say, $28 an hour for a helper — and think that's the cost. It's closer to the floor. The U.S. Bureau of Labor Statistics publishes the Employer Costs for Employee Compensation report quarterly. The December 2025 release shows that wages and salaries represent 70.1 percent of total employer compensation for private industry workers. The other 29.9 percent goes to legally required benefits, insurance, and employer-paid payroll taxes.

That ratio means for every dollar you pay in wages, you spend roughly 43 cents more before you've bought a single tool or put a mile on a truck for your new hire.

Part of that burden is fixed by law. The IRS sets the employer's share of FICA at 7.65 percent of wages in 2026 — 6.2 percent for Social Security and 1.45 percent for Medicare. Federal and state unemployment insurance adds another two to four percent depending on your state. Workers' compensation insurance compounds on top of that, and for trade contractors working electrical, HVAC, plumbing, or roofing jobs, it's one of the steeper line items in the burden stack because it's priced to the physical risk of the work.

The BLS Occupational Employment and Wage Statistics from May 2025 put median hourly wages at $34.37 for electricians, $34.70 for plumbers and pipefitters, and $32.75 for HVAC mechanics and installers. Apply the BLS compensation ratio — where wages are 70.1% of total cost — and the picture shifts:

These numbers don't include equipment, a second vehicle, phone plans, or the hours you'll spend managing and supervising someone new. They're just the payroll burden — the minimum floor of what a hire costs you per working hour.

The break-even formula for your first hire

Before you post a job listing, run this four-step calculation:

1. Find your true hourly labor cost. Take the hourly wage you plan to offer and multiply by 1.43. That's the BLS burden factor from the ECEC data — total compensation divided by wages. If you plan to pay $28/hr, your true payroll cost is roughly $40/hr.

2. Estimate realistic billable hours for year one. A new hire won't fill your calendar immediately. Training takes time, callbacks eat hours, and scheduling won't be seamless. Budget 1,200–1,500 billable hours in year one — roughly 60–75% of a full-time schedule. An experienced tech you can hand off to immediately may hit 1,500. A newer technician or apprentice may be closer to 1,000.

3. Calculate your annual labor cost. Multiply true hourly rate by projected billable hours. At $28/hr wage (× 1.43 = $40/hr true cost) over 1,300 billable hours, that's roughly $52,000 per year in payroll alone — before tools, insurance, or truck costs.

4. Calculate the revenue required to cover it. Divide annual labor cost by your net margin per billed labor hour. If you bill at $110/hr and your overhead allocates to $40/hr in combined material and overhead cost, your labor margin is $70/hr. To cover $52,000 in payroll, the new tech needs to generate at least $52,000 in labor margin — meaning they need to bill roughly 743 hours at your labor margin rate just to break even on payroll alone.

That's the test: is 743 hours of qualified work already waiting, or are you betting on generating it? If it's already in backlog or near-certain pipeline, the hire is fundable. If you're counting on growth to materialize after you hire, you're taking a cash flow bet.

Before running step four, check your current labor margin per hour using the free markup calculator. If you're unclear what you're actually netting per billed hour after overhead, your break-even estimate will be wrong before you start.

When raising your rates makes more sense than hiring

Here's a trap worth flagging before you commit to the overhead. If you're turning down work because you're booked out three weeks, you don't necessarily have a capacity problem — you might have a pricing problem.

A three-week backlog is a signal that your market will accept higher rates. Before you add fixed overhead, try increasing your service call rate by 15–20 percent. Higher rates will price out some of your lowest-margin calls, which frees up the slots that the rest of the backlog fills. You end up with fewer jobs, higher margin per job, and no new payroll burden.

The math usually works in your favor. A solo HVAC tech who raises rates 15 percent and loses 10 percent of call volume takes home more, drives fewer miles, and spends more time per job — which is often better for close rate and repeat business too. Hire when a rate increase alone can't close the gap, or when you have a specific category of work you can confidently delegate while you move up to higher-value calls.

How to test demand before you fully commit

If you're not certain the backlog is durable — not just a busy quarter — a full W-2 hire is a significant bet. Two lower-commitment ways to test first:

Use a licensed 1099 subcontractor for 90 days. A subcontractor handles overflow at a negotiated day rate. You pay per job, carry no payroll burden, and find out whether the demand actually holds through a slow period. Before you set a day rate you'll negotiate with a sub, calculate your minimum hourly rate so you know the floor below which the arrangement stops being profitable for you.

Start with an apprentice or helper at a lower wage. A helper at $18–$22/hr has a much lower break-even than a journeyman. You trade productivity per hour for lower cost per hour. This works well if you can delegate specific task categories — material pickups, site prep, cleanup, straightforward installs — while you stay on the diagnostic and technical calls that command your billing rate.

Track your job volume and backlog through at least three consecutive months, including one that covers your trade's slow season. Durable demand through a soft month is the signal that an employee will stay productive enough to justify the fixed cost.

Takeaways

• Hire when you're consistently turning down profitable work, your close rate is strong, and solo revenue is at $80K or more — not just when one month feels hectic.
• The BLS Employer Costs for Employee Compensation report shows wages are 70.1% of total employer compensation; budget roughly 43% above the wage rate for actual payroll cost.
• The IRS employer FICA share is 7.65% of wages; mandatory costs including unemployment and workers' comp routinely bring the total burden to 20–30% above wages before any discretionary benefits.
• Run the four-step break-even: (wage × 1.43) × projected billable hours = annual labor cost; divide by your labor margin per hour to find the revenue the hire must generate just to pay for itself.
• If your calendar is full, try a rate increase before committing to fixed overhead — a 15–20% rate increase often costs less than a hire and solves the capacity pressure.

What your quote volume tells you before you post that listing

The clearest early signal that you're ready to hire isn't a full calendar — it's a quote pipeline that outpaces your ability to execute. When you're sending 15–20 quotes a month, winning half of them, and still can't clear the backlog, your business has enough predictable demand to support a hire without relying on future growth to fund it.

That kind of visibility into your own quote volume — what you're winning, what's pending, and what margin you're actually making per job — is what makes the break-even math real instead of theoretical. JobEstimator gives solo contractors a running picture of their quote load, win rate, and billing targets without the spreadsheet work. If you're at the stage where your pipeline is outrunning your bandwidth, plans start at $39/mo.
