Why Disability Insurance Matters

Your ability to earn income is your most valuable financial asset. A 30-year-old earning $75,000/year will earn approximately $2.6 million before retirement. Disability insurance protects this earning power. According to the Social Security Administration, 1 in 4 workers will experience a disability lasting 90+ days before age 65. Yet fewer than 40% of private-sector workers have long-term disability coverage. Most disabilities are not dramatic injuries — they are back problems, cancer, mental health conditions, and cardiovascular issues.

How Much Coverage You Need

Standard recommendation: replace 60-70% of gross income. This matches most policy maximums and, because disability benefits from individual policies are tax-free (if you pay premiums with after-tax dollars), 60% of gross approximately equals your take-home pay. Factor in: spouse income, employer coverage, Social Security Disability (SSDI), and savings runway. The gap between your essential expenses and guaranteed income sources is what your individual policy should cover.

Frequently asked questions
How much does disability insurance cost?
Individual long-term disability insurance typically costs 1-3% of your annual salary. For a $75,000 earner seeking $4,500/month in coverage: approximately $75-150/month. Factors affecting price: age, health, occupation (desk jobs cheaper than physical labor), benefit period, and waiting period. A 90-day waiting period (vs 30 days) cuts premiums 15-25%.
What is the difference between short and long-term disability?
Short-term disability (STD) covers the first 3-6 months of disability, typically at 60-70% of salary. Long-term disability (LTD) starts after STD ends and can last years or until age 65. Many employers provide STD but not LTD. If you only have one, prioritize LTD — a long-term disability is financially devastating without it.
