Contractor vs Employee for a Solo Founder: 2026 Math

Run the cost math, then let classification and the practical tradeoffs make the call: the cheapest structure on paper is often the wrong one once reclassification exposure, flexibility and continuity are counted. This is the classification-and-tradeoffs part of the hire-or-contract series. For the column-by-column cost build, see FTE vs contractor cost math; for the decision frame, start with how to decide: hire or contract.

1. The decision: $120k base, $95/hr contractor

The scenario: a solo founder hiring an engineer for close to full-time work. W-2 option: $120,000 salary. Contractor option: $95 an hour for 1,800 billable hours a year. For scale, the median annual wage for US software developers was $135,980 in May 2025^[4], so substitute your own market's salary and rate; the method does not change.

The employer costs used: employer social security and Medicare at 7.65%, federal unemployment of $42 after the standard state credit^[5], health insurance of $7,885 (the 2025 average single premium of $9,325 less the $1,440 average worker contribution)^[3], and a 4% retirement match. State unemployment ($540), workers' compensation (0.5% of payroll) and equipment ($2,400) are assumptions to replace with your state's rate, your insurer's quote and your own setup.

2. W-2: $145,447 fully loaded

The W-2 cost breakdown and the contractor comparison both come from one engine run:

$25,447 of costs on top of salary, 1.21 times salary. That is a little below the 1.24x to 1.29x that BLS compensation data imply for a salaried hire^[1] (derived in the true loaded cost of an employee), because this example leaves out items such as bonuses and life or disability insurance. Paid vacation and holidays are not added: the salary already pays for them.

3. Contractor: $171,000 at 1,800 hours

The contractor option is simpler: $95 × 1,800 hours = $171,000 a year, reported directly in the engine block above (contractorAnnualCost). That is $25,553 more than the employee, or 17.6%. The intuition that contractors are cheaper because there are no benefits fails once the hours approach full time: the employee's fixed costs are spread over a whole year of work, while every contractor hour is billed at the full rate.

4. The break-even: about 1,530 hours

The contractor costs the same as the employee at $145,447 ÷ $95 = 1,531 hours a year, about 29 hours a week across 52 weeks. Below that, paying for hours used beats paying a salary; above it, the employee is cheaper. The engine reports the same break-even the other way round: at 1,800 hours, a contractor charging $80.80 an hour would match the employee's cost.

The break-even moves with the rate: at $120 an hour it falls to about 1,210 hours, at $150 to about 970. The cheaper the contractor, the more hours it takes before employment wins on cost.

5. Classification decides before cost does

Whether a worker is a contractor depends on the relationship, not on the contract. The IRS looks at behavioral control, financial control and the type of relationship^[2]; the Department of Labor applies an economic-reality test for wage-and-hour law^[7]. A contractor billing 1,800 hours a year to one client, on that client's schedule and tools, with no end date, fits the employee pattern regardless of the paperwork.

The federal tax cost of getting it wrong is computable. If a worker is reclassified and the error was not intentional disregard, section 3509 sets the employer's liability for the taxes it failed to withhold at 1.5% of wages for income tax and 20% of the employee's share of social security and Medicare (3% and 40% if information returns were not filed), and the employer's own 7.65% share is owed in full^[6]. On $171,000 that is $13,082 + $2,565 + $2,616 = about $18,300 for one year, before unemployment taxes, interest, penalties and any wage or benefits claims under labor law.

So the order of the decision is classification first, then cost. If the work genuinely is independent and project-scoped, the cost math decides. If it looks like employment, hire an employee.

6. Flexibility, continuity and onboarding

• Flexibility. A contract can usually end at the end of its term with nothing else owed. Ending employment is more involved: US law generally does not require severance, but state final-pay rules apply, an unemployment claim can raise your state tax rate, and a badly handled termination carries legal risk. For a founder unsure the work will last, the contractor's reversibility is worth something even when it costs more.
• Continuity. Knowledge of your product, code and customers accumulates inside an employee. A contractor carries it out at the end of the engagement unless you pay for handover and documentation.
• Onboarding. Both structures pay for ramp time. A one-month contract of 168 hours at $95 where the first week runs at 50% and the second at 75% delivers 20 + 30 + 88 = 138 productive hours, an effective $115.65 an hour. Short engagements carry the ramp over fewer hours, so their effective rate sits well above the headline rate.
• Equity. Employees at early-stage companies often expect options. That is a non-cash cost on the employee side, borne by existing shareholders, so including it makes the employee more expensive in total even though it saves cash.

7. The decision rule for solo founders

• Independent, project-scoped work below the break-even hours: contractor. Cost favours it, and the work pattern supports the classification.
• Ongoing, close to full-time work integrated into your team: employee. Cost and classification point the same way.
• A specialist you need occasionally: contractor regardless of rate; the alternative is paying for a full-time role you cannot fill.
• Tight cash: narrow the scope to work a contractor can genuinely own, or hire part-time; do not run a full-time "contractor".

Many small companies end up with a mix: employees for the core roles that need continuity, and contractors for specialized or variable work such as design, accounting, legal and occasional development.

Frequently asked questions

Is a contractor at $95/hour cheaper than a $120k employee?

Not at 1,800 hours a year. With 2026 payroll taxes, the 2025 average employer share of a single health plan and a 4% match, the calculator puts the employee at $145,447 a year against $171,000 for the contractor, $25,553 more. The contractor would have to charge $80.80 an hour to match the employee's cost at 1,800 hours. And a contractor billing that many hours to one client fits the IRS and Department of Labor pattern of an employee, so the classification question usually settles it first.

When do contractors beat employees on cost?

When the work needs fewer hours than the employee's cost buys at the contractor's rate. In this example that is $145,447 ÷ $95 = about 1,530 hours a year, roughly 29 hours a week. Below that, paying the contractor only for hours used costs less than a full salary; above it, the employee costs less per hour. Part-time, project-scoped work is also where contractor classification is easiest to defend.

What are the W-2 hidden costs?

$25,447 above a $120,000 salary in this example: employer social security and Medicare $9,180, federal unemployment $42 after the state credit, state unemployment $540 (assumed), workers' compensation $600 (0.5%, assumed), health insurance $7,885 (the 2025 KFF average single premium of $9,325 less the $1,440 average worker contribution), a 4% retirement match of $4,800 and $2,400 of equipment. That is 1.21 times salary, a little below the 1.24x to 1.29x that BLS compensation data imply for a salaried hire, because the example leaves out items such as bonuses and life or disability insurance.
