What Is Disability Insurance and Do You Need It?

Most people insure their car and home, but forget to insure their most valuable asset: their ability to earn income. A 35-year-old has a 50% chance of experiencing a disability lasting 90+ days before retirement. Disability insurance is the coverage most people overlook — until they need it.

What Is Disability Insurance?

Disability insurance replaces a portion of your income — typically 60–70% — if illness or injury prevents you from working. Unlike workers' compensation (which only covers workplace injuries), disability insurance covers any illness or injury, including cancer, heart disease, and mental health conditions — which cause the majority of long-term disability claims.

Short-Term vs Long-Term Disability Insurance

Short-term disability (STD) kicks in quickly — often after 7–14 days — and covers 3–6 months. Long-term disability (LTD) has a longer waiting period (the 'elimination period,' typically 90 days) but covers years or until retirement age. Most financial advisors recommend both, with STD bridging the gap until LTD begins.

• Short-term: covers 3–6 months, lower cost, shorter wait
• Long-term: covers years or until 65, higher cost, 60–90 day wait
• Elimination period: the wait before benefits begin (longer = cheaper premium)
• Benefit period: how long you receive payments (to age 65 is ideal)

Own-Occupation vs Any-Occupation Coverage

This distinction matters enormously. 'Own-occupation' pays benefits if you can't perform your specific job — a surgeon who injures their hand gets benefits even if they could work a desk job. 'Any-occupation' only pays if you can't work any job at all. Own-occupation coverage is significantly better but costs more. If you have a specialized profession, it's worth the premium.

How Much Coverage Do You Need?

Aim for 60–70% of your gross income. Most employer-provided plans cap at 60%. If you have significant savings or a working spouse, you might need less. Consider your fixed monthly expenses — mortgage, car payment, food — and make sure your benefit covers them.

What Does Disability Insurance Cost?

Expect to pay 1–3% of your annual income for a comprehensive long-term disability policy. A person earning $80,000/year might pay $800–$2,400/year. Factors that affect cost: age (younger = cheaper), health, occupation (riskier job = higher premium), elimination period, and benefit period.

Do You Really Need It?

If you live paycheck to paycheck, have dependents, or don't have 6+ months of expenses saved, disability insurance is not optional — it's essential. The Social Security disability program exists but it's notoriously difficult to qualify for and pays very little. Your emergency fund covers short gaps; disability insurance covers the long ones.
