Last reviewed: July 23, 2026

This tool provides an illustrative income-replacement gap and cost estimate for long-term disability insurance — not a quote from any insurer.

How to use this calculator

  • Enter your income

    Monthly income and the percentage you'd want replaced if you couldn't work.

  • Add employer coverage

    The percentage of income your employer's group LTD plan already covers, if any.

  • Pick your occupation risk

    Office, field, or manual work — this is the biggest driver of the premium estimate.

  • Read the gap and cost

    See the monthly benefit gap and an illustrative annual/monthly premium to close it.

Inputs used

  • Age
  • Monthly income
  • Target income-replacement percentage
  • Employer-provided LTD coverage percentage
  • Occupation risk class

Formula basis

  • Coverage gap = (income × target replacement %) − (income × employer coverage %)
  • Estimated annual premium = annual coverage gap × 2% base rate × age multiplier × occupation multiplier

Assumptions and limits

  • 2% of the covered annual benefit is used as an illustrative base rate for individual LTD riders — real quotes commonly range 1–3%
  • Does not model elimination periods, benefit periods, or own-occupation vs. any-occupation policy definitions, which materially affect real pricing
  • Occupation risk is simplified to three broad classes; real underwriting uses detailed job-class tables

Frequently asked questions

Employer-provided long-term disability (LTD) often replaces only 50–60% of income and may be capped at a low dollar amount. Many people supplement it with an individual policy to close the gap, which is what the coverage-gap figure above estimates.

Insurers price disability coverage heavily on injury/illness risk tied to your job. Physically demanding occupations carry meaningfully higher premiums than desk jobs for the same benefit amount.

No — this estimates long-term disability (LTD) coverage, which kicks in after a waiting period and can last years. Short-term disability is a separate, usually employer-provided benefit for shorter absences.
