Locum vs W-2 Calculator: The Complete Guide to Comparing Contract and Staff Pay for Healthcare Professionals in 2026

The Locum Decision: More Than Just an Hourly Rate

Dr. Chen is a hospitalist earning $260,000 per year as a W-2 employee at a community hospital in Ohio. A locum tenens staffing agency contacts her with an offer: $200 per hour for a 13-week assignment in rural Nebraska, with housing and travel covered. On the surface, $200/hour × 2,080 hours = $416,000 — a 60% raise. But Dr. Chen knows that locum rates and W-2 salaries are not directly comparable. The W-2 job carries benefits worth tens of thousands of dollars, while the locum role requires her to pay self-employment tax, buy her own health insurance, and fund her own retirement.

For locum tenens providers across all specialties — physicians, nurse practitioners, CRNAs, physician assistants, and dentists — the decision to go independent is not just about the hourly rate. It is about the full after-tax, after-benefits picture. That is where a locum vs W-2 calculator becomes essential. This guide explains exactly how the comparison works, what costs you need to account for, and how to use a calculator to make an informed decision.

Why Healthcare Professionals Need a Locum vs W-2 Calculator

Healthcare professionals face a unique decision that most other industries do not. The locum tenens market offers high hourly rates, flexible schedules, and geographic freedom — but it also strips away the stability and benefits of W-2 employment. A locum vs W-2 calculator helps answer the fundamental question: at what locum hourly rate do you actually break even with a W-2 salary?

The three biggest factors that a locum vs W-2 calculator accounts for are:

1. Self-employment tax: As a 1099 locum provider, you pay both the employer and employee shares of Social Security (12.4%) and Medicare (2.9%) — totaling 15.3% on your net self-employment income. A W-2 employer covers half of that cost.
2. Benefits gap: W-2 positions typically include health insurance, malpractice insurance, retirement matching, and paid time off. Locum providers must fund all of these independently.
3. Income variability: Locum assignments are temporary. Gaps between contracts mean unpaid time that a W-2 salary would cover.

How to Use a Locum vs W-2 Calculator

A proper locum vs W-2 calculator walks you through each cost category so you can see the true break-even rate. Here is the step-by-step process:

Step 1: Enter Your W-2 Compensation Details

Start with your current W-2 salary and the value of your benefits package. Include health insurance premiums paid by your employer, 401(k) match, PTO value, and any other employer-provided benefits.

Step 2: Estimate Your Locum Costs

As a 1099 locum provider, you will need to account for:

• Self-employment tax (15.3% on net earnings)
• Health insurance premiums (individual or family)
• Malpractice insurance (if not provided by the staffing agency)
• Retirement contributions (SEP-IRA, Solo 401(k))
• Unpaid time between assignments
• Licensing, credentialing, and CME costs

Step 3: Compare the Results

The calculator will show you the locum hourly rate needed to match your current W-2 total compensation. Anything above that rate is a genuine increase in take-home value.

Real-World Example: Hospitalist in Ohio

Let us return to Dr. Chen. Her W-2 package includes:

• Base salary: $260,000
• Employer health insurance contribution: $12,000
• 401(k) match (4%): $10,400
• PTO value (20 days): $10,000
• Malpractice insurance: $8,000
• Total W-2 compensation: $300,400

To match that as a locum provider, Dr. Chen would need to earn approximately $185-$195 per hour working 48 weeks per year, after accounting for self-employment tax, her own health insurance, malpractice coverage, and retirement savings. The $200/hour offer looks attractive, but the margin is thinner than the headline number suggests.

When Locum Makes Sense Despite the Math

Even when the hourly rate does not fully compensate for lost benefits, many healthcare professionals choose locum work for other reasons:

• Flexibility: Choose when and where you work.
• Geographic exploration: Try different cities before committing.
• Burnout prevention: Take extended time off between assignments.
• Skill development: Work in diverse clinical settings.
• Debt payoff: Aggressively pay down student loans during high-earning periods.

The key is going in with eyes open. A locum vs W-2 calculator gives you the financial clarity to make the decision that is right for your career and your life.

If you are also considering a W-2 role with a traditional paycheck, you may want to use a W-2 paycheck calculator to understand your take-home pay after federal and state withholdings.
