Disability Insurance

Insurance that replaces a portion of your income if you become unable to work due to illness or injury — available in short-term (weeks to months) and long-term (years to retirement) forms.

Disability insurance provides income replacement when an employee is unable to work due to a non-work-related illness or injury. (Work-related injuries are covered by workers' compensation, a separate system.) It comes in two forms: short-term disability (STD) and long-term disability (LTD). STD typically begins after a brief elimination period (0–14 days of disability) and pays benefits for 3–6 months. LTD begins after STD is exhausted — typically after 90–180 days of disability — and may pay benefits for years or until retirement age, depending on the policy. Together, they're designed to provide a continuum of income protection for any disability lasting from a few weeks to the rest of a working life.

Disability is the most statistically likely major financial risk most working-age adults face, yet it's consistently underinsured. Social Security Disability Insurance (SSDI) exists as a federal fallback, but it's notoriously difficult to qualify for (most initial applications are denied), pays below most workers' pre-disability income, and has a 5-month waiting period before benefits begin. Many workers assume workers' compensation would cover them, but workers' comp only applies to workplace injuries — a heart attack, cancer diagnosis, car accident, or mental health crisis is covered by disability insurance, not workers' comp.

Employer-provided group disability insurance is typically inexpensive and may be partially or fully employer-funded, but comes with limitations: benefits are usually 60% of base salary, may not include bonus or equity income, and cease when you leave the employer. For higher earners and those with significant financial obligations, individual disability insurance policies purchased independently fill the gap — they're portable, can be structured to cover a higher percentage of income, and are guaranteed renewable. Own-occupation policies (which pay if you can't perform your specific occupation) are stronger protection than any-occupation policies (which only pay if you can't perform any work at all).

Short-Term vs. Long-Term Disability

Short-term disability (STD) covers the initial period of inability to work — typically the first 3–6 months. It usually begins after a brief waiting period of a few days to two weeks and pays 60–80% of your base salary. Long-term disability (LTD) takes over when STD is exhausted and the disability continues. LTD benefit periods range from two years to 'to age 65' depending on the policy — the longer the benefit period, the more valuable (and typically more expensive) the coverage. Most employer group plans provide STD and LTD, often at no or low cost to the employee. If your employer doesn't offer both, consider purchasing an individual policy — the income you're protecting is worth far more than the premium.

What to Look for in a Disability Policy

  • Benefit amount: typically 60% of base salary for group plans. Higher earners may need a supplemental individual policy to cover the full income gap.
  • Elimination period: how long you must be disabled before benefits begin. Shorter is better; 90 days is common for LTD.
  • Benefit period: how long benefits are paid. 'To age 65' is the gold standard for LTD; 2-year or 5-year benefit periods leave significant risk.
  • Definition of disability: 'own occupation' (can't do your specific job) is stronger protection than 'any occupation' (can't do any job at all). Own-occupation is standard in professional group plans.
  • Non-cancelable vs. guaranteed renewable: individual policies that are non-cancelable cannot be changed or priced up while you own them — important for long-term planning.
  • Social Security integration: some group LTD policies offset benefits by SSDI payments — understand whether this applies and by how much.

Example

A 38-year-old software engineer earns $160,000 and is diagnosed with a serious illness requiring six months of treatment. Her employer's STD plan pays 70% of base salary ($112,000 annualized) for the first three months, with a 7-day elimination period. Her employer's LTD plan then begins at 60% of base ($96,000 annualized) and will pay until she returns to work or reaches 65, whichever comes first. Without this coverage, she would have needed to drain savings within weeks.
