How the disability insurance calculator works

Long-term disability replaces a portion of your income if illness or injury keeps you from working. The math is straightforward:

Recommended benefit = Gross monthly income × Replacement %
Coverage gap = Recommended benefit − Existing benefit

We target roughly 60% of gross income because individual policy benefits are usually tax-free when you pay the premium with after-tax dollars — so 60% of gross often equals close to 100% of your take-home pay.

The premium estimate uses the industry rule of thumb of 1–3% of income, adjusted for age, benefit period and elimination period.

Why your income is worth insuring

A 35-year-old earning $84,000 who works to 65 will earn roughly $2.5 million, more with raises. The Social Security Administration estimates more than one in four of today's 20-year-olds will experience a disabling condition before retirement. Yet disability is the coverage people most often skip.

How to optimize what you pay

  • Lengthen the elimination period. Moving from 90 to 180 days can cut the premium 10–20% if your emergency fund can bridge the gap.
  • Buy young. Rates rise steeply with age and any new diagnosis can add exclusions.
  • Use employer coverage as the base and add an individual policy for the untaxed top-up.
  • Add a future-increase option so you can raise the benefit as your income grows without new underwriting.
  • Skip the shortest benefit periods unless budget forces it — the point of the coverage is a long or permanent disability.

Disability insurance calculator FAQ

Short-term vs long-term disability?

Short-term covers weeks to a few months and is often employer-provided. Long-term is the one that protects against a career-ending event and is what this calculator sizes.

Are benefits taxable?

If you pay premiums with after-tax money, benefits are generally tax-free. If your employer pays, benefits are usually taxable. That is why the 60% target is used.

What is "own occupation"?

A definition that pays if you cannot perform your specific occupation, even if you could work in another field. It costs more but matters for specialized professionals.
