Principal Financial Group is the second most commonly recommended disability insurance carrier for physicians — and for a specific reason that has nothing to do with marketing. Its application process is efficient, rates are competitive, and underwriting is fair.
The single most operationally significant advantage Principal holds over Guardian in 2026 is its female physician rate structure — the only Big 5 carrier with historically preferential rates for women. That advantage can represent $500 to $1,500 in annual premium savings for women physicians. But you must add the Regular Occupation rider — without it, you do not have true own-occupation coverage.
Principal Financial Group: Company Overview
Principal Financial Group is headquartered in Des Moines, Iowa, and was founded in 1879 — making it one of the oldest financial services companies in the country. Principal ranks among the FORTUNE 500 corporations and is a global investment management leader with a large U.S. insurance division focused on life and disability insurance.
Individual disability insurance through Principal is underwritten and issued by Principal Life Insurance Company, the primary insurance subsidiary within the Principal Financial Group family.
Financial Strength Ratings (2026)
| Rating Agency | Principal Rating |
|---|---|
| A.M. Best | A+ (Superior) — second highest possible |
| Moody's | A1 (Good) |
| S&P | A+ (Strong) |
| Fitch | AA- (Very Strong) |
Principal's A+ rating from A.M. Best is the second-highest possible — one notch below Guardian's A++ but still within the elite tier of carrier financial strength. For disability insurance coverage that may need to pay claims 20 to 30 years from the date of purchase, both A+ and A++ represent genuinely strong carriers. The one-notch difference is real but not practically decisive for most physicians choosing between Guardian and Principal.
The Principal Income Protector Policy: What's in the Box
Principal's current individual disability income policy for physicians is called Income Protector (Series 700). This replaced their earlier HH750 series and is the policy physicians receive quotes on today.
Core Policy Features
- •Non-cancelable and guaranteed renewable to age 65: Principal cannot cancel your policy, raise your premiums, or change your benefits as long as you pay your premiums. After age 65, the policy is conditionally renewable on an annual basis.
- •Elimination period options: 30, 60, 90, 180, or 365 days. The 90-day period is the most commonly selected and most cost-effective for physicians with adequate emergency reserves.
- •Benefit period options: 2 years, 5 years, to age 65, or to age 67. "To age 65" or "to age 67" is the appropriate selection for most physicians.
- •Monthly benefit maximum: Subject to underwriting. Principal can coordinate with other carrier policies — particularly relevant for physicians stacking multiple carrier policies to reach the IRS-approved maximum benefit level.
Built-In Benefits (No Additional Premium)
- •Presumptive disability benefit: If you suffer permanent loss of speech, hearing in both ears, sight in both eyes, or use of both hands, both feet, or one hand and one foot, benefits are payable immediately without an elimination period and continue regardless of your ability to work or earn income.
- •Rehabilitation benefit: If you are disabled and participate in an approved rehabilitation program, Principal provides an additional benefit to help cover program costs — an incentive structure designed to support return-to-work efforts.
- •Waiver of premium: Your disability insurance premiums are waived during a qualifying disability claim — standard across all Big 5 carriers.
- •Organ donor benefit: A built-in provision providing a short-term benefit if you are disabled as a result of donating an organ. Particularly relevant for physicians in clinical specialties where organ donation discussion is part of their practice culture.
Understanding Principal's Definition Structure: The Most Important Section
This is where Principal requires more careful reading than any other Big 5 carrier — because Principal offers multiple definition levels, and the base policy does not contain the true own-occupation definition that physicians require. Getting this wrong is the most common mistake physicians make when purchasing a Principal policy.
The Base Policy Definition: Own-Occupation, Not Working
Under the base policy definition of total disability, you must be unable to perform the substantial and material duties of your own occupation and you are not working. Own occupation is defined as your specialty if you are limited to a professionally recognized specialty in medicine or dentistry.
This is the “own-occupation, not working” definition — which pays benefits if you cannot perform your specialty AND you are not working in another occupation. If you become disabled and take another job — even in a completely unrelated field — benefits stop.
This is not the definition most physicians want. A neurosurgeon who develops essential tremor and cannot operate, but consults for a pharmaceutical company, receives zero benefit under this definition. The definition punishes physicians who stay productive and financially active after a disabling event.
The Regular Occupation Rider: True Own-Occupation
To access true own-occupation coverage from Principal, you must add the Regular Occupation rider to the base policy. This rider changes the total disability definition so that if you are unable to perform the substantial and material duties of your occupation, your benefit payment would not be reduced if you begin working in another occupation.
With the Regular Occupation rider in place: a neurosurgeon who cannot operate but takes a pharmaceutical consulting role at $300,000 per year receives their full monthly disability benefit — regardless of what they earn in the alternative occupation.
The worksite modification language — Principal's unique nuance:
Principal's definition states that there must be no reasonable job or worksite modifications that would enable you to perform your own occupation. In practice, most physician disability claims involve conditions that no worksite modification can remedy: essential tremor, chronic pain, psychiatric conditions, progressive neurological disease. For most physician disability claims, this distinction has no practical consequence. For a small number of borderline scenarios — a physician who could potentially continue with equipment modifications or schedule adjustments — this language creates an opening for Principal to contest eligibility that other carriers do not have.
The critical takeaway: Always add the Regular Occupation rider to a Principal policy. Without it, you do not have true own-occupation coverage. The rider is non-negotiable for any physician purchasing a Principal policy.
The Transitional Occupation Rider: The Alternative Path
The Transitional Occupation rider eliminates the worksite modification language — providing a cleaner true own-occupation definition without that caveat. The trade-off is an income offset provision: if you work in another occupation and your combined disability benefit plus new income exceeds your pre-disability income, your disability benefit is reduced accordingly.
The Transitional Occupation rider is most appropriate for physicians who:
- •Want to eliminate the worksite modification language
- •Are pursuing PSLF or expect to work in a lower-income capacity after disability
- •Prioritize unlimited mental/nervous coverage (available with the Transitional rider in many specialties)
- •Are willing to accept the income offset in exchange for the cleaner definition
The right rider choice between Regular Occupation and Transitional Occupation depends on your specialty, your anticipated post-disability work plans, and your mental/nervous coverage priorities. This is exactly where the guidance of an experienced independent broker matters — not because either choice is wrong, but because the optimal selection is specific to your situation.
Principal's Key Riders for Physicians
Maximize Your Benefit Rider (FPO): Principal's Most Distinctive Feature
Principal offers a unique future purchase option, the Maximize Your Benefit rider, that you will not find with other insurance carriers. Rather than fixed exercise dates, it allows coverage increases based on documented income growth — you can request an increase any time your sustained earnings have grown by at least 15 percent since your last increase, or when you experience a qualifying event such as losing group LTD coverage.
Your coverage can be reviewed every three years to ensure it is consistent with changes to your income. You can even request an advanced update in place of your next scheduled review if you have at least a 15 percent increase in sustainable earnings since the later of the policy issue date or last adjustment.
How this differs from standard FIO riders: Standard Future Increase Options at other carriers require you to exercise at fixed dates or lose the option. Principal's Maximize Your Benefit rider is income-triggered — you increase coverage when your income justifies it, not on a carrier-set schedule. For physicians with rapidly growing incomes — early attendings, those entering partnership, practice owners adding ASC income — this flexibility is materially more useful.
Residual Disability Rider
Pays proportional benefits when you are partially disabled — working but earning less than your pre-disability income due to your disabling condition. Principal's residual rider uses an income loss test: if your income loss from the disability exceeds a specified percentage of pre-disability income, you qualify for residual benefits proportional to the income loss.
The residual rider is essential for most physician disability policies because the most common physician disability scenarios involve partial rather than total loss of function. A physician managing chronic pain who reduces their schedule from 5 days to 3 days per week is partially disabled. Without a residual rider, these physicians receive zero benefit — the policy only pays when they cannot perform their specialty at all.
COLA Rider (Cost-of-Living Adjustment)
Principal's COLA benefit is increased on a compound basis, with options at 3 percent or 6 percent. A $10,000 monthly benefit growing at 3 percent compound reaches approximately $18,000 after 20 years, preserving substantial purchasing power against long-term inflation. Upon returning to work full time, you keep any increased disability benefit without having to provide evidence of good health — a meaningful consumer protection for episodic or recurring disabilities.
Catastrophic Disability Rider
Provides a monthly benefit of $5,000 in addition to your monthly disability benefit in the event you become catastrophically disabled — losing the ability to perform two or more activities of daily living without assistance, becoming cognitively impaired, or becoming presumptively disabled. This additional income layer stacks on top of the standard benefit for the most severe disability scenarios.
Lump Sum Benefit
A one-time lump-sum benefit of $60,000 is payable if you suffer a total loss of use without any possibility of recovery of the sight in one eye, or the use of a hand or foot. This benefit is payable in addition to any other benefit of the policy you qualify to receive — providing immediate capital to adjust lifestyle and environment following a catastrophic acute disability.
Mental/Nervous Disorder Coverage: The Two-Path Approach
Principal gives physicians the explicit option to have a policy with no limitation (benefit period matches your selected benefit period) or a 24-month limitation (with an additional 10 percent premium discount). For anesthesiologists and emergency room physicians, the 24-month mental/nervous limitation is mandatory under Principal's underwriting guidelines.
Important for anesthesiologists and EM physicians: These specialties face Principal's mandatory 24-month mental/nervous limitation — and also carry the highest documented burnout rates in medicine. Burnout, depression, anxiety disorders, and substance use disorders are documented physician disability risks. For these specialties, Guardian or Ameritas may be preferable, as they do not impose the 24-month limitation.
Principal's Female Physician Pricing Advantage
This is the most practically significant reason female physicians frequently choose Principal over Guardian and other carriers.
Most physician disability insurance carriers price women significantly higher than men. The industry standard justification is actuarial — women file more disability claims across most categories, particularly in the 30 to 50 age range, and carriers price accordingly.
Principal's underwriting approach to female physician pricing has historically been more favorable than competitors — in some specialty-age combinations offering rates that are 15 to 25 percent lower for women than comparable Guardian quotes. For a female physician purchasing a $10,000 monthly benefit with a to-age-65 benefit period and standard riders, the difference between Guardian and Principal in annual premium can range from $800 to $2,000 depending on specialty and age. Over a 30-year policy hold, that differential compounds to $24,000 to $60,000 in total premium savings.
Note: The female pricing advantage has varied over time and varies by specialty and state. Always obtain comparative quotes from both Principal and Guardian specifically before a female physician makes a carrier selection based on price. The advantage is real and consistent but not uniform across all specialty-state-age combinations.
Principal Disability Insurance Cost: What to Expect
Principal is generally priced in the middle tier of the Big 5 carriers — less expensive than Guardian for most physician profiles (particularly women), and more expensive than Ameritas. Here are illustrative 2026 annual premium ranges for male physicians — these are not quotes, and individual pricing requires a specific illustration from a licensed broker:
| Specialty | Monthly Benefit | Approx. Annual Premium (Male) |
|---|---|---|
| Family medicine / Internal medicine | $5,000 | $2,000–$3,200 |
| Emergency medicine | $5,000 | $2,800–$4,200 |
| General surgery | $7,500 | $5,200–$8,400 |
| Orthopedic surgery | $10,000 | $7,800–$12,600 |
| OB/GYN | $7,500 | $5,800–$9,600 |
| Anesthesiology | $7,500 | $4,600–$7,200 |
| Psychiatry | $5,000 | $1,600–$2,600 |
Ranges reflect 90-day elimination period, to-age-65 benefit period, with Regular Occupation rider and core riders. For female physicians, Principal's pricing may be 10 to 30 percent more favorable relative to Guardian.
Professional association discounts: Principal offers discounts through physician professional associations, state medical societies, and hospital systems that can reduce premiums by 10 to 30 percent. Always ask your broker what discount programs apply before accepting any initial quote.
Principal vs. Guardian: The Definitive Comparison
The two most common physician disability carrier finalists are Guardian and Principal. Here is a direct comparison on the dimensions that matter most for physician policy selection:
| Factor | Principal | Guardian |
|---|---|---|
| Own-occ definition | True OO with Regular Occupation rider (worksite modification language) | Enhanced True OO — strongest available |
| Base policy definition | Own-occupation, not working (weaker — add rider) | True own-occupation built in |
| Mental/nervous | Unlimited option available; 24-month mandatory for anesthesia & EM | Unlimited for most specialties built in |
| Female physician pricing | Most competitive of Big 5 | Standard gendered pricing (higher for women) |
| A.M. Best rating | A+ | A++ |
| Future increase flexibility | Maximize Your Benefit — income-triggered, more flexible | Standard FIO with fixed exercise dates |
| Cost vs. Guardian | Generally 10–25% less expensive | Most expensive of Big 5 |
| GSI for residents | Strong | Widest in industry |
| Lump sum benefit | Yes ($60,000) | Limited |
When Principal wins:
- Female physicians where the pricing advantage is material
- Physicians who want income-triggered FIO flexibility
- Physicians who want unlimited mental/nervous without Guardian's premium
- Most cognitive and non-procedural specialties
When Guardian wins:
- Surgical specialists with mixed procedure + clinic income
- Anesthesiologists and EM physicians (mandatory 24-month MN at Principal)
- Physicians whose training program only has a Guardian GSI
- Physicians prioritizing the absolute strongest claims definition
Who Should Buy Principal Disability Insurance
Principal is the strongest choice for:
- ✓Female physicians in most specialties. The pricing advantage at Principal is real and meaningful for women physicians who will hold this policy for 25 to 35 years. At the same coverage level, lower premiums over a multi-decade hold represent genuine financial value.
- ✓Physicians who want the Maximize Your Benefit rider's income-triggered flexibility. Physicians with volatile or rapidly growing income — early attendings, those entering partnership, practice owners adding ASC distributions — benefit from the ability to increase coverage based on documented income rather than waiting for fixed exercise dates.
- ✓Physicians who want unlimited mental/nervous coverage at lower cost than Guardian. The ability to elect unlimited mental/nervous protection at a lower premium than Guardian is a meaningful value proposition for physicians in high-burnout specialties (excluding anesthesiologists and EM physicians subject to the mandatory 24-month limitation).
- ✓Physicians comparing Principal vs. Guardian on price for non-procedural specialties where Guardian's Enhanced formula has limited practical value. For most cognitive specialties, Principal's true own-occupation definition with the Regular Occupation rider provides equivalent protection at lower cost.
Principal may not be the best fit for:
- ✗Anesthesiologists and emergency medicine physicians who face Principal's mandatory 24-month mental/nervous limitation. Given the documented burnout rates in these specialties, accepting a 24-month mental/nervous cap creates real exposure. Guardian or Ameritas may be preferable.
- ✗Surgical specialists with significant mixed income who benefit from Guardian's Enhanced source-of-earnings formula for ophthalmologists, OB/GYNs, urologists, and ENT surgeons with the specific income profile Guardian's enhanced definition addresses.
- ✗Residents at training programs where only Guardian has a GSI program — in which case GSI availability overrides the carrier comparison for the initial resident policy.

Frequently Asked Questions
Is Principal disability insurance good for physicians?
Overall, Principal is a good choice for physicians. With the Regular Occupation rider in place, Principal delivers a strong true own-occupation definition at generally competitive pricing. For female physicians in particular, Principal's pricing advantage makes it frequently the preferred carrier on a cost-adjusted basis.
What is the difference between Principal's Regular Occupation and Transitional Occupation riders?
The Regular Occupation rider delivers true own-occupation coverage — full benefits if you cannot perform your specialty, even while working in another occupation — but includes worksite modification language unique to Principal. The Transitional Occupation rider eliminates that language but introduces an income offset provision that reduces your benefit if other income plus the disability benefit exceed your pre-disability income. The right choice depends on your specialty, anticipated post-disability work plans, and mental/nervous coverage needs.
Does Principal disability insurance cover mental health disabilities?
Principal offers two options: unlimited duration (benefit period matches your elected benefit period) or a 24-month limitation (with a 10 percent premium discount). For anesthesiologists and emergency medicine physicians, the 24-month limitation is mandatory under Principal's underwriting guidelines. For all other specialties, unlimited coverage is recommended for most physicians in high-burnout fields.
How does Principal's Maximize Your Benefit rider differ from a standard Future Increase Option?
Standard FIO riders allow benefit increases at fixed exercise dates — typically annually or every 3 years. Principal's Maximize Your Benefit rider allows increases any time your sustained earnings grow by at least 15 percent, or upon qualifying events like losing group LTD coverage. This income-triggered structure is more flexible for physicians with variable or rapidly growing incomes.
Is Principal cheaper than Guardian for physician disability insurance?
Generally yes — Principal's pricing runs 10 to 25 percent below Guardian for most physician profiles, with the differential most pronounced for female physicians. Whether the price difference justifies choosing one over the other depends on whether Guardian's Enhanced definition has practical value for your specific specialty and income structure.
Can residents purchase Principal disability insurance?
Yes. Principal participates in GSI programs at many residency training programs — allowing residents to purchase individual disability insurance without individual medical underwriting. GSI availability varies by institution. If your training program does not have a Principal GSI program, a fully underwritten individual application is also available.
