Locums or Employed: The Physician Trade-Off in Plain Numbers

Deconstructing the High Daily Rate

The initial appeal of locum tenens work for a physician is almost always the number. A daily rate of $2,200, $2,600, or even higher for in-demand specialties, creates a powerful illusion of wealth. When multiplied by five days a week, 48 weeks a year, the gross income figures seem to dwarf a standard employed salary. A hospitalist earning a $320,000 salary might see a colleague pull in a theoretical $528,000 working 220 shifts at $2,400 per day. This initial, simplistic math is the hook that draws many into considering the transition. However, this comparison is fundamentally flawed because it pits a gross, unburdened number against a fully loaded one. An employed physician's salary is only one part of their total compensation package, a package that the locums physician must replicate piece by piece out of their own pocket.

A more accurate analysis begins by breaking down the time component of that daily rate. A typical locums shift is not a nine-to-five day; it's often a 10- or 12-hour commitment. At $2,400 for a 12-hour shift, the hourly rate is $200. While still impressive, it reframes the compensation from a monolithic daily sum to a rate for time worked. Furthermore, that rate is paid only for days on assignment. Unlike an employed physician who receives paid time off for vacations, holidays, and sick days, the locums practitioner earns nothing on days they do not work. Taking a two-week vacation costs not just the price of the trip, but also ten days of lost income, a sum that could easily exceed $24,000. An unexpected illness or family emergency carries the same direct financial penalty.

The true financial picture only emerges when you begin subtracting the costs that an employer typically bears. The high daily rate is not just a payment for clinical services; it is a payment that must cover health insurance, disability insurance, retirement funding, the employer's share of payroll taxes, and professional licensing and credentialing fees. When these expenses are properly accounted for, the impressive gross income shrinks considerably. The locums physician is not an employee; they are a small business owner, and the daily rate is their business's gross revenue, not their personal salary. The failure to grasp this distinction is the single most common and costly mistake a physician makes when transitioning away from traditional employment.

The Benefits Black Hole You Fund Yourself

For an employed physician, benefits are often an abstraction, a series of automatic deductions and employer contributions that happen in the background. For the independent locum tenens physician, these benefits become concrete, expensive line items that must be sourced and paid for directly. Health insurance is the most significant of these. An employer-sponsored family health plan, even a high-deductible one, might cost an employee $600 per month in premiums. The employer’s contribution, which is invisible to the employee, is often another $1,500 to $2,000 per month. The locums physician is responsible for the entire premium, easily totaling $25,000 to $30,000 per year for a comprehensive family plan purchased on the open market. This single expense can erase the perceived income advantage of several weeks of work.

Beyond health insurance lies disability coverage, a non-negotiable protection for any physician whose income depends on their ability to work. Employer-provided long-term disability plans are a standard part of most compensation packages. As an independent contractor, a physician must purchase their own policy. A robust, own-occupation disability policy for a physician can cost between $6,000 and $10,000 annually, depending on their age, specialty, and health status. This is another significant expense that comes directly from the locums daily rate. Life insurance, while less expensive, adds another few thousand dollars a year to the ledger if a physician wants to provide the same level of security their family would have had under an employer's group plan.

These are not optional expenses. Going without health or disability insurance as a high-income earner is an act of extreme financial negligence. The risk of a single major health event or an accident leading to an inability to work could bankrupt a physician who has failed to secure this protection. The psychological comfort of knowing that an employer's human resources department has vetted and managed these plans is also gone. The locums physician must become their own benefits administrator, spending time and energy researching plans, comparing quotes from brokers, and managing enrollment and payments. This administrative time is unpaid, further chipping away at the true hourly value of their clinical work.

Malpractice and the Tail You're Chasing

Malpractice insurance is a cost every practicing physician bears, but the structure of that coverage differs dramatically between employed and locum tenens positions. Most hospitals and large practice groups provide their physicians with "occurrence-based" malpractice policies. This is the gold standard of coverage. It protects the physician from any incident that occurred during their employment, regardless of when a claim is filed. If a patient sues you five years after you’ve left a hospital for an event that happened while you were there, the occurrence policy from that former employer still covers you. You can leave the job and have permanent peace of mind. This type of coverage is expensive, so it is rarely offered in temporary assignments.

Instead, locum tenens assignments almost universally come with "claims-made" malpractice insurance. The staffing agency or hospital provides coverage, but it only protects you while the policy is active—that is, while you are working that specific assignment. The moment your contract ends, so does your protection. If a claim is filed six months after you leave, you are completely uninsured for that incident unless you have purchased a separate policy extension known as a "tail." This tail coverage is a one-time purchase that extends the reporting period for claims indefinitely, effectively converting your claims-made policy into the equivalent of an occurrence policy for that specific block of time worked.

The cost of tail coverage is the most overlooked financial time bomb in locum tenens work. The price is calculated as a multiple of the original annual premium, typically ranging from 150% to 300%. For a surgeon in a high-risk specialty, where the annual malpractice premium might be $25,000, the tail coverage for a year of work could be a one-time payment of $50,000 to $75,000. Some locums agencies may cover this cost after a physician works with them for a certain length of time, but many do not. The physician is then left with a difficult choice: pay the exorbitant fee out-of-pocket, go without coverage and hope no claims arise (a practice known as "going bare," which is professionally reckless), or string together continuous locums assignments with the same agency to keep the claims-made policy active, sacrificing flexibility. Forgetting to clarify who pays for the tail before signing a contract can lead to a five-figure surprise at the end of an assignment.

The Tax Man Cometh: 1099 vs. W-2

The shift from a W-2 employee to a 1099 independent contractor introduces a significant and often underestimated tax burden. As a W-2 employee, you pay your share of FICA taxes (Social Security and Medicare), which amounts to 7.65% of your income up to the annual Social Security wage base. Your employer pays a matching 7.65%, for a total of 15.3% contributed to the system. You only see your half deducted from your paycheck, making the employer's contribution invisible but very real. When you become a 1099 contractor, you are considered both the employee and the employer. Consequently, you are responsible for paying the entire 15.3% yourself, a tax known as the self-employment tax.

This doubling of the FICA tax rate creates an immediate, substantial reduction in take-home pay. For 2024, the tax is 15.3% on the first $168,600 of net self-employment income. This means a locums physician will pay an extra $12,898 in federal taxes compared to an employed physician with the same income, simply to cover the employer's portion of FICA. While one-half of the self-employment tax paid is deductible, this only slightly mitigates the impact. This is not an abstract accounting detail; it is a direct cash cost that must be factored into any income comparison. A locums physician grossing $450,000 is not simply in a higher income bracket; they are subject to a different and more burdensome tax structure on a foundational level.

Furthermore, the mechanics of paying taxes change completely. As a 1099 contractor, you no longer have taxes withheld from each paycheck. You are required to calculate your own tax liability and make estimated tax payments to the IRS and state tax authorities on a quarterly basis. This requires careful record-keeping of income and expenses, as well as the discipline to set aside a large portion of each payment—often 30-40% or more—into a separate bank account specifically for taxes. Failing to make these quarterly payments, or underpaying them significantly, results in financial penalties and interest charges from the IRS. The convenience of automated payroll deductions is replaced by a quarterly administrative chore with real financial consequences for mistakes.

Retirement on Your Own Terms (and Dime)

One of the most valuable long-term financial benefits of traditional employment is access to an employer-sponsored retirement plan, such as a 401(k) or 403(b), particularly one with an employer match. This match is essentially free money that significantly accelerates wealth accumulation. For instance, a hospital system offering a 50% match on the first 6% of an employee's contributions on a $350,000 salary provides an additional $10,500 in retirement savings each year. Over a career, this employer contribution, compounded by market growth, can amount to hundreds of thousands of dollars. When a physician opts for locum tenens work, they walk away from this powerful wealth-building tool.

As a 1099 contractor, the responsibility for retirement savings falls entirely on the physician's shoulders. While they gain access to powerful retirement vehicles designed for the self-employed, such as a SEP IRA or a Solo 401(k), they must fund these accounts entirely on their own. A SEP IRA allows for a contribution of up to 25% of net adjusted self-employment income, while a Solo 401(k) allows both an "employee" contribution up to the annual limit plus an "employer" profit-sharing contribution. These plans can enable a physician to save even more than they could in a standard employer plan. However, every single dollar comes directly from their gross locums revenue.

The critical difference is the absence of the match. To equal the retirement savings of an employed colleague receiving a $10,500 annual match, the locums physician must not only save their own portion but also an additional $10,500 just to break even. This is a direct reduction from the cash flow that could have been used for other goals. Many physicians new to locums work are so focused on the high gross income and the immediate costs of insurance and taxes that they neglect or underfund their retirement accounts. They fail to appreciate that the employer match is a core part of total compensation, and its absence creates a significant financial drag that must be actively overcome through higher personal savings rates.

The Unpaid Administrative Burden

A hidden cost of the locum tenens lifestyle is the significant amount of unpaid time spent on administrative tasks, chief among them being credentialing and licensing. For an employed physician starting a new job, a dedicated hospital department or administrative assistant typically handles the mountain of paperwork required to get them credentialed with the facility and enrolled with insurance payers. For a locums physician, this burden often falls on them, or requires constant follow-up with the staffing agency's credentialing specialist. Each new assignment at a different facility requires a new, full credentialing process. This involves completing lengthy applications, providing documentation for every phase of their education and career, and submitting to background checks, all of which can take dozens of hours.

The most financially dangerous aspect of credentialing is the lag time. A physician cannot begin work, and therefore cannot get paid, until the hospital's medical staff office grants privileges. It is a common and disastrous mistake to give notice at a permanent job based on a verbal agreement or even a signed locums contract, assuming a start date is firm. The credentialing process at a typical hospital takes 90 to 120 days, and sometimes longer if there are any complexities in the physician's history. A staffing agency might promise a 60-day turnaround, but they are not in control of the hospital's internal bureaucracy. A physician who quits their $300,000-a-year job expecting to start a locums assignment on July 1st might find that privileges aren't granted until September 1st, creating an unplanned two-month gap with zero income.

This downtime risk is a permanent feature of locums work. Assignments can be canceled at the last minute due to changing hospital census, leaving the physician with a sudden income gap. Finding and vetting the next assignment takes time and effort, all of which is unpaid. The locums physician must build a financial buffer to withstand these inevitable periods of uncompensated time. Thinking in terms of annual income requires planning not for 52 weeks of work, but perhaps 44 or 46, with the rest budgeted as potential downtime between contracts. This reality stands in stark contrast to the stability of an employed role, where the paycheck arrives every two weeks regardless of daily patient volume or administrative delays.

The Physical and Emotional Toll of the Road

While not a direct line item on a spreadsheet, the physical and emotional wear and tear of constant travel represents a real cost that impacts both quality of life and long-term earning potential. The typical locum tenens arrangement involves flying to the assignment location at the beginning of the work block and flying home at the end. For a physician working a Monday-to-Friday schedule, this means Sunday afternoon is lost to packing and traveling to the airport, and Friday evening is spent in transit, often arriving home late and exhausted. This effectively shortens the weekend at home to a single full day, placing significant strain on family relationships, parenting, and personal well-being. The novelty of travel quickly wears off, replaced by the monotony of security lines, flight delays, and rental car counters.

The financial costs of this lifestyle are also frequently underestimated. While the agency typically covers flights, lodging, and a rental car, the daily per diem for meals is often modest. A $50 per day food allowance may sound reasonable, but it rarely covers the cost of three healthy meals a day, especially in high-cost areas. Physicians often find themselves paying out-of-pocket for better food or resorting to unhealthy, convenient options. Living in a hotel for weeks or months at a time also creates ancillary costs, from laundry services to the temptation of on-demand movies and room service. These small expenses accumulate, creating a steady financial drain not present for the physician who goes home to their own kitchen every night.

This constant state of transit and temporary living can lead to burnout more quickly than in a stable role. The physician is perpetually the "new person" at the hospital, lacking the deep professional relationships and support systems that develop over time in a permanent position. They may feel isolated and disconnected from the hospital community. This emotional toll can impact clinical performance and job satisfaction, leading some physicians to leave locums work after only a year or two. The disruption and instability are a hidden price paid for the flexibility and high gross pay, a price that every physician must carefully consider before committing to this demanding career path.

The Three-Year Financial Showdown

To understand who truly comes out ahead, we must model a realistic three-year financial comparison. Let's consider a hospitalist. The employed physician accepts a position with a $350,000 annual salary. Their total compensation is much higher: add a $15,000 retirement match, and a benefits package (health, disability, life insurance) worth approximately $28,000 per year. Their total annual compensation value is $393,000. Over three years, this is a stable, predictable $1,179,000 in total value, with paid time off and the security of occurrence-based malpractice coverage. Their primary financial tasks are managing their budget and investing their 401(k) contributions.

Now, consider the locum tenens hospitalist. They secure a rate of $2,300 per day and plan to work 190 shifts per year, anticipating some downtime. Their gross revenue is $437,000 annually. From this, we must subtract the costs of being a business. First, the benefits: $28,000 per year to replicate the employer's plan. Next, the extra self-employment tax: approximately $13,000 more than their employed counterpart. Let's assume they wisely purchase tail coverage after a year-long assignment, a one-time cost of $25,000. They must also personally fund the $15,000 their employed peer gets as a retirement match. Finally, we'll budget for four weeks of unpaid downtime per year due to credentialing lags or contract gaps, representing about $35,000 in lost potential revenue. The "real" annual pre-tax income is closer to $346,000, and that's before accounting for the administrative hours. Over three years, the locums physician's net advantage may be negligible or even negative, despite a higher gross revenue.

The physician who comes out ahead in a locums career is the one who operates with extreme discipline. They negotiate rates that are high enough to cover all hidden costs, secure contracts that include payment for tail coverage, and maintain a significant cash reserve (at least 3-6 months of living expenses) to weather income gaps. They are masters of their own budget, maxing out a Solo 401(k) and working with accountants to optimize tax deductions. The physician who struggles is the one seduced by the gross daily rate, who fails to budget for benefits and taxes, and who lives paycheck to paycheck, leaving them financially vulnerable when a contract ends abruptly. The decision is less about pure numbers and more about your tolerance for risk and your willingness to become a meticulous business owner. For your first step this week, call an independent insurance broker to get a hard quote for a family health plan and an own-occupation disability policy. Then, find an accountant who specializes in 1099 income for a one-hour consultation. These two calls will replace abstract numbers with the concrete costs that will define your financial reality.
