An educational estimate, not personalized financial advice. Insurers typically cap coverage at 60-80% of income to preserve work incentive - actual available coverage depends on the specific insurer and policy.

The formula

Target monthly benefit = (Annual Income / 12) x Income Replacement % Coverage gap = Target benefit - Existing employer/individual coverage
Example

$80,000 annual income at 60% replacement: a target monthly benefit of $4,000. If your employer already provides $2,000/month in long-term disability coverage, your remaining coverage gap is $2,000/month to fill with an individual policy.

Step-by-step guide

  1. Enter your annual pre-tax income.
  2. Choose a replacement percentage - 60% is the industry standard baseline; some people target 70% for tighter budgets.
  3. Enter any existing coverage from an employer group policy, and see your remaining gap to fill with individual coverage.

Why insurers cap coverage below 100% of income

Disability insurers deliberately limit coverage to 60-80% of income, even though your bills don't shrink when you can't work - this is intentional, not an oversight. Full income replacement would remove any financial incentive to return to work when medically able, so insurers cap benefits below full salary to preserve that incentive. There's an important upside, though: disability benefits are generally tax-free when you pay premiums with after-tax dollars, meaning a 60% benefit often replaces closer to 80-90% of your actual prior take-home pay once the tax difference is factored in.

Common mistakes

Assuming Social Security Disability (SSDI) will cover the gap - SSDI benefits are typically modest, average around $1,500-2,000/month, require a 5-month waiting period, and have a low initial approval rate, making it an unreliable primary source of income protection.
Not accounting for a group employer policy's group cap - high earners often find their employer's group LTD plan caps out around $10,000-15,000/month regardless of actual salary, requiring supplemental individual coverage for the excess.

Frequently asked questions

Is disability insurance really more important than life insurance?

Statistically, the odds favor it - the Social Security Administration estimates roughly 1 in 4 of today's 20-year-olds will become disabled before reaching retirement age, a meaningfully higher probability than dying during working years.

What's the difference between short-term and long-term disability insurance?

Short-term disability typically covers the first 3-6 months with a short waiting period, often provided free by employers. Long-term disability kicks in after that and can pay benefits for years, sometimes until age 65 - and is generally considered more financially important, since major disabilities tend to last far longer than a few months.

What does "own occupation" vs. "any occupation" mean in a policy?

"Own occupation" coverage pays out if you can't perform your specific job, even if you could theoretically do other work. "Any occupation" is stricter, requiring that you're unable to work in any job you're reasonably qualified for. Own-occupation coverage is more protective and typically costs more.
