What This Calculator Does

This tool helps you estimate how much income you'd receive under short-term versus long-term disability insurance, based on your salary and benefit structure.

It's ideal for evaluating employer benefits or comparing private disability policies.

How the Comparison Works

Short-Term Disability (STD):

  • Covers temporary illnesses or injuries
  • Usually replaces 50–70% of income
  • Benefits last 6–26 weeks
  • Has little or no waiting period

Long-Term Disability (LTD):

  • Begins after a waiting/elimination period (90–180 days)
  • Replaces 50–70% of income
  • Can last 2 years, 5 years, or until retirement
  • May be offered through employers or private insurers

The calculator projects your total covered income, compares it to your living expenses, and estimates your coverage gap, the shortfall you may need to cover with savings or supplemental insurance.

Example Scenario

Scenario Details:

  • • Monthly income: $6,000
  • • Short-term coverage: 60% for 13 weeks
  • • Long-term coverage: 60% for 5 years after 90 days waiting period

If disabled for 1 year:

  • • Short-term benefit: $9,000 (13 weeks × $3,000)
  • • Long-term benefit: $27,000 (9 months × $3,000)
  • • Total income replacement: $36,000
  • • Uncovered loss: $36,000 (assuming 12 months total income = $72,000)

Result: The person maintains 50% of total income, adequate for basic needs but potentially requiring supplemental coverage.

Why Disability Insurance Matters
CauseAvg. DurationCommon Coverage Needed
Back or joint injuries2–6 monthsSTD + LTD
Cancer recovery6–18 monthsLTD
Heart conditions6–12 monthsLTD
Mental health conditions3–9 monthsSTD + LTD

Important: Nearly 1 in 4 working Americans will experience a disability before retirement (SSA, 2025). Having both STD and LTD ensures continuity of income protection.

Tips for Better Coverage
  • Check your elimination period, a longer waiting period can reduce premium cost.
  • Coordinate STD and LTD so LTD starts right after STD ends.
  • Review definition of disability (own-occupation vs. any-occupation).
  • Consider inflation protection riders for long-term policies.
  • Review employer benefits annually, many cover only short-term disability.
