Disability Insurance: The Coverage Most People Skip That They Need Most

Most people insure their car, home, and even their life. They don't insure their most valuable financial asset: their income. A 30-year-old has a 1-in-4 chance of being disabled for 90+ days before age 65. Without disability insurance, one health event ends your income — and most families are one paycheck from financial collapse.

The employer group LTD problem

Most employer LTD policies have features that sound good but severely limit protection:

Own-occupation vs. any-occupation is the most important distinction in disability insurance. "Own-occupation" pays if you can't perform the duties of your specific occupation — even if you could theoretically work in another role. This is the gold standard and is critical for high-income professionals (physicians, dentists, attorneys, engineers). "Any-occupation" is significantly weaker — and what most employer group policies use after 24 months.

How much individual disability coverage to buy

Target: 60–70% of your gross income in total disability income (employer LTD + individual policy). Steps:

  1. Calculate 60% of your monthly gross income
  2. Subtract your employer LTD benefit (check your benefits summary)
  3. The gap is the target benefit amount for an individual policy
  4. Your emergency fund determines your elimination period — 90 days if you have 3+ months saved; 60 days if less

Example: $120,000 annual income. 60% = $6,000/month target. Employer covers $4,500/month. Individual policy needed: $1,500/month.

What disability insurance costs

ProfileMonthly BenefitMonthly PremiumAnnual Cost
35yr male, office work, to age 65$3,000/mo$75–$120/mo$900–$1,440
35yr female, office work, to age 65$3,000/mo$100–$160/mo$1,200–$1,920
40yr physician, own-occ, to age 65$10,000/mo$400–$700/mo$4,800–$8,400

Women pay more — statistically higher claim rates. Occupation class matters significantly — manual labor classes cost more than office work. The best time to buy: when you're young and healthy. Premiums lock in at purchase; health deterioration later can't raise existing policy rates.
