Disability Income Insurance

Domain 4 tests income replacement: definitions of disability, timing, benefit calculation, offsets, and renewability.

Core mechanics

  • Benefit amount is a percentage of pre-disability income, typically 60–70%; insurers cap total benefits so they plus other income do not exceed a set share of income, preserving the incentive to return to work.
  • Elimination (waiting) period: 30–180 days on long-term plans; short-term plans commonly use 0–14 days with benefits lasting up to six months. A longer elimination period lowers premium.
  • Benefit period: 1, 2, or 5 years, to age 65, or lifetime (rare).
  • Own occupation pays if you cannot perform your own occupation - broader and more expensive, often limited to 2–5 years. Any occupation pays only if you cannot perform any occupation for which you are reasonably suited by education, training, or experience.
  • Residual/partial disability pays a proportional benefit when income falls but the insured still works; presumptive disability pays full benefits for loss of sight, hearing, speech, or two limbs without proof of income loss.
  • Renewability: noncancelable guarantees both premium and benefits; guaranteed renewable allows class-wide premium increases but no cancellation; conditionally and optionally renewable shift more risk to the insured.

Worked example

Monthly income $6,000; policy pays 60%; 90-day elimination period; Social Security offset $1,100.

  1. Gross monthly benefit: 60% × $6,000 = $3,600.
  2. Subtract the $1,100 offset → $2,500 payable.
  3. Disability beginning March 1 with a 90-day elimination period means benefits start about June 1, assuming continuous disability.

Tax and setting

Benefits are tax-free when the insured paid premiums with after-tax dollars; employer-paid premiums make benefits taxable. Occupational coverage pays for work-related injury (workers' compensation is usually primary); nonoccupational coverage excludes it. Business uses include key-person disability and business overhead expense (BOE) policies, the latter usually with short benefit periods.

Traps

  • Assuming own-occupation applies for the entire benefit period.
  • Ignoring offsets when computing the payable benefit.
  • Mixing up the elimination period (before benefits) with the benefit period (how long they last).
  • Forgetting that residual benefits require an actual income loss.
