The Social Security Administration estimates that more than 1 in 4 of today's 20-year-olds will experience a disability before retirement. The percentage who carry private disability insurance: less than 1 in 5.
Disability insurance is the coverage that pays a portion of your income when you can't work due to illness or injury. For families who depend on a working person's paycheck, it's at least as important as life insurance — and far less commonly carried.
What disability insurance actually does
It replaces a percentage of your income (typically 60 to 70 percent) for as long as you're disabled and unable to work, up to the policy's benefit period. Some policies pay for 2 years, some until age 65 or 67.
It's not the same as workers' comp (which only covers work-related injuries) or Social Security disability (which has strict definitions and typical 6+ month approval delays). Private disability insurance pays for ANY disabling condition, regardless of cause, and usually starts paying after a short waiting period (90 to 180 days).
The two flavors: short-term and long-term
Short-term disability (STD)
Pays for the first weeks to months after a disabling event. Usually 3 to 12 months max. Often provided by employers as a benefit. California's State Disability Insurance (SDI) provides up to 52 weeks at 60 to 70 percent of wages, capped at a weekly maximum.
Long-term disability (LTD)
Picks up where STD ends. Pays until you can return to work or the policy's benefit period ends. The more important coverage for catastrophic situations — a back injury that ends a career, MS or other chronic illness, a stroke at 50.
California SDI: what it covers and doesn't
California's State Disability Insurance is funded through payroll deductions. It pays up to 52 weeks at a percentage of wages (currently up to 70 percent for lower earners, 60 percent for higher earners), but is capped at a weekly maximum that becomes inadequate for higher incomes.
For a California worker earning $100,000+, SDI alone replaces well under half of their income, for a maximum of one year. If a disability extends beyond that, there's no further SDI benefit. This is where long-term disability matters.
Employer-provided LTD: usually inadequate
Many employers offer group long-term disability as a benefit. Common structure: 60 percent of base salary, capped at a monthly maximum (often $5,000 to $10,000), with a 90- or 180-day elimination period.
Three common limitations
- Base salary only — bonus, commission, and equity income may be excluded
- Benefits taxed as income (because employer paid premiums) — your net replacement is more like 40 to 45 percent
- Ends if you leave the job — no portability
Individual disability insurance fills the gaps
Buying your own policy lets you:
- Increase your income replacement above the group cap
- Receive tax-free benefits (because you paid premiums with after-tax dollars)
- Keep the coverage if you leave your job or change employers
- Lock in coverage based on your current health for the long term
What to evaluate in a policy
Own-occupation vs any-occupation
'Own occupation' means the policy pays if you can't perform YOUR specific job, even if you could do something else. 'Any occupation' means it only pays if you can't do any reasonable work. Own-occupation is significantly more valuable, especially for professionals (surgeons, attorneys, engineers) whose specialized skills are what they're really insuring.
Elimination period
How long you wait before benefits start, after disability. 90 and 180 days are most common. Shorter = higher premium.
Benefit period
How long benefits last. 5-year, 10-year, and to-age-65 (or 67) are common. To-age-65 is most expensive but most valuable for catastrophic situations.
Cost of living adjustment (COLA)
Annual benefit increase to keep up with inflation. Worth the extra premium for long benefit periods — a flat benefit loses value over a 20-year disability.
Non-cancelable and guaranteed renewable
Both features prevent the insurer from canceling your policy or raising rates as long as you pay premiums. Both worth requesting.
Who needs it most
- Single-income families (no second earner to cover the gap)
- Self-employed and 1099 workers (no group coverage at all)
- Professionals whose income depends on specialized skills (surgeons, dentists, attorneys)
- Anyone whose lifestyle requires their full income
What it costs
Roughly 1 to 3 percent of annual income for a strong individual LTD policy. A $100,000 earner might pay $1,500 to $3,000 a year for a $5,000/month benefit to age 65 with own-occupation language.
Not cheap. But the protection is enormous and the probability of using it is much higher than people think.
