What Is Disability Insurance?
Disability insurance (also called income replacement insurance or disability income insurance) pays a monthly benefit—typically 60–70% of your pre-disability income—if you become unable to work due to illness or injury. It protects the income that funds your life: your mortgage, your family, your retirement savings.
Statistic: The Social Security Administration estimates that 1 in 4 20-year-olds will become disabled before retirement. The average long-term disability claim lasts 31.6 months. Without disability coverage, that's nearly 3 years without income.
Short-Term vs. Long-Term Disability Insurance
| Feature | Short-Term Disability (STD) | Long-Term Disability (LTD) |
|---|---|---|
| Benefit period | 3–6 months | 2–5 years, or to age 65 |
| Elimination period (wait) | 0–14 days | 60–180 days |
| Benefit amount | 60–80% of income | 60–70% of income |
| Typical cost | 0.5–1% of annual salary | 1–4% of annual salary |
| Common source | Employer-provided | Employer or individual policy |
Own-Occupation vs. Any-Occupation Disability
This is the most important distinction in disability insurance—and the one most people overlook until claim time:
- Own-occupation ("own-occ"): Pays benefits if you can't perform the duties of your specific occupation. A surgeon who develops hand tremors and can no longer operate collects full benefits even if they could work as a medical consultant. This is the gold standard for professionals.
- Any-occupation: Only pays if you're unable to perform any occupation for which you're reasonably qualified. A surgeon with hand tremors who can work a desk job collects nothing. Cheaper, but provides far less protection.
- Modified own-occ (hybrid): Own-occ definition during the first 2–5 years, then converts to any-occ. Common in group policies.
Professionals—physicians, lawyers, dentists, architects—should only buy own-occupation disability insurance. The premium difference is modest; the claims difference is enormous.

How Much Disability Insurance Do You Need?
The general rule: replace 60–70% of your gross income. Benefits from an individual policy are typically tax-free (if you pay premiums with after-tax dollars), so 60% of gross often approximates your take-home pay.
| Annual Income | Target Monthly Benefit | Approximate Annual Premium |
|---|---|---|
| $75,000 | ~$3,750/mo | ~$1,500–$2,500 |
| $150,000 | ~$7,500/mo | ~$3,000–$5,000 |
| $300,000 | ~$15,000/mo | ~$6,000–$10,000 |
| $500,000 | ~$20,000–$25,000/mo | ~$12,000–$18,000 |

Frequently Asked Questions
Individual long-term disability insurance typically costs 1–4% of your annual income. A physician earning $300K might pay $6,000–$10,000/year for own-occupation coverage to age 65. Premiums vary by occupation, health class, benefit amount, elimination period, and policy features.
For most working adults who rely on their income—especially professionals, business owners, and anyone without substantial savings—disability insurance is among the most important policies they can own. The probability of a long-term disability before retirement is significantly higher than the probability of dying prematurely.
Own-occupation disability insurance pays benefits if you can no longer perform the specific duties of your own occupation—even if you could work in a different job. A surgeon with a hand injury who can no longer operate collects full benefits. This is the standard for professional coverage and is more expensive than any-occupation policies.
Yes. Individual disability insurance is available to self-employed individuals, and it's especially important since they have no employer-provided coverage or paid sick leave. Carriers underwrite based on net business income, typically covering up to 60–70% of documented income.
