A W2 agency assignment still makes you an employee of the staffing company. It is different from a corporation-to-corporation engagement and different from 1099 self-employment. Convert the full-time salary and agency wage to annual pay using paid hours, then compare employee insurance cost, paid time, retirement match, other benefits, and assignment gaps. Use the [W2 vs 1099 calculator](/calculators/w2-vs-1099) to enter either annual W2 salary or an hourly W2 wage and solve the agency break-even rate.
Start with the correct employment arrangement#
“Contract” describes a project or assignment, but it does not identify who employs the worker. In a W2 agency arrangement, the staffing firm generally pays wages and reports them on Form W-2. In a true C2C arrangement, a business supplies services to another business. A 1099 independent contractor is self-employed for the engagement. Those arrangements have different payroll, insurance, benefit, and administrative consequences.
Ask who will issue the year-end tax form, who controls payroll withholding, whether overtime rules apply, and which company provides benefits. If the proposal is actually C2C, use the W2 vs C2C calculator. The IRS worker-classification overview explains that the substance of the relationship matters; a label in an email does not settle classification.
Convert the full-time offer to comparable annual pay#
Suppose the full-time offer pays $100,000 a year. The agency offer pays $52 per hour for 40 hours a week. If all 52 weeks were paid, the agency gross would be $108,160. That simple multiplication is only a starting point.
Assume ten client holidays and ten personal days are unpaid. At eight hours a day, that removes 160 hours and $8,320 of wages. Agency gross falls to $99,840. The apparent $8,160 lead over salary has become a $160 shortfall before comparing benefits.
The calculator’s hourly W2 input makes the reverse conversion visible:
- Enter $52 as the W2 hourly wage.
- Enter 40 paid hours per week.
- Enter the paid weeks supported by the offer.
- Compare that annualized amount with the agency schedule and unpaid client closures.
Use the offer’s actual paid-time policy. Do not subtract vacation from an annual salary when the salary continues during that vacation, and do not add “PTO value” on top of the same salary. Both changes would count the same pay twice.
Add the benefits that change your cash flow#
Continue the example with these annual differences:
| Item | Full-time | W2 agency |
|---|---|---|
| Gross pay after unpaid agency days | $100,000 | $99,840 |
| Employee health premiums | $3,000 | $5,400 |
| Employer retirement match | $4,000 | $0 |
| Employer HSA contribution | $1,000 | $0 |
| Other employer-paid benefit value | $0 | $1,000 |
The agency option now needs to replace $2,400 of additional health cost and $4,000 of retirement match, partly offset by $1,000 of other benefits. That is a $5,400 annual gap before considering assignment risk. Across 1,920 paid agency hours, replacing the gap alone takes about $2.81 per hour. An approximate target becomes $54.81 per hour, with taxes and exact benefit treatment still to be modeled.
Price the gap between assignments#
An hourly offer can be attractive during a fully staffed year and weak when a project ends early. Model a central case and a conservative case. For example, four unpaid weeks reduce a 40-hour schedule by 160 hours. At $55 per hour, the reduction is $8,800 of gross pay.
Do not automatically demand payment for every possible risk. Decide which risk you can absorb, how much emergency cash you have, whether the staffing firm redeploys workers, and whether the assignment has a guaranteed term. The purpose of a buffer is to expose the tradeoff, not to create a universal markup.
Review the hourly rate and the complete offer#
Before accepting, compare the written terms for overtime, paid holidays, sick time, health-plan eligibility date, employer retirement contributions, bonus eligibility, equipment, training, travel, background checks, and termination notice. The U.S. Department of Labor overtime fact sheet provides federal context, but state law and the actual role can add requirements.
Run the worked numbers in the W2 vs 1099 calculator, then use the salary vs hourly calculator if expected overtime and actual worked hours are central to the choice. A useful target rate replaces the package you would really lose, not a generic percentage added to salary.
Checklist#
- Confirm the employer and tax form.
- Convert both offers to annual pay using paid hours.
- Keep employee premiums separate from employer benefit value.
- Treat paid leave as pay already included in salary.
- Test holidays, personal leave, and assignment gaps.
- Compare spendable cash and total benefit value separately.
- Get rate, overtime, benefits, and assignment terms in writing.
