What is disability insurance?

Disability insurance replaces a portion of your income (typically 50-70%) if you become unable to work due to illness or injury. It protects your most valuable asset—your earning power.

How much disability insurance do I need?

Most policies cover 50-70% of your gross income. Employer plans typically offer 60% of salary. Private policies may allow up to 70-80% of after-tax income to avoid over-insurance.

Is disability insurance worth it?

Yes. 1 in 4 workers will experience a disability lasting 90+ days before age 65. Without coverage, you'd have no income during recovery. It's especially important for high earners and those without large savings.

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

Short-term disability (STD) covers the first 3-6 months of disability. Long-term disability (LTD) kicks in after STD ends and can last until age 65. Most people need LTD more than STD.

How Disability Insurance Works

The Basics

Term	Definition
Benefit amount	Monthly payment you receive (50-70% of income)
Elimination period	Waiting period before benefits begin
Benefit period	How long benefits last
Definition of disability	What qualifies you to receive benefits

Example: $100,000 Salary with LTD

Policy Feature	Terms	Your Coverage
Benefit amount	60% of salary	$5,000/month
Elimination period	90 days	Wait 3 months before benefits
Benefit period	To age 65	Up to 27 years (if disabled at 38)
Monthly cost	2% of salary	~$167/month

Definitions of Disability

The definition determines when you get paid. This is the MOST important policy feature.

“Own Occupation” (Best)

Feature	Details
Definition	Unable to perform your specific occupation
Example	Surgeon can’t operate but could teach
Benefit	Receives disability even if working another job
Cost	Most expensive
Best for	Specialists, high earners

“Any Occupation” (Cheapest, Worst)

Feature	Details
Definition	Unable to perform ANY job you’re qualified for
Example	Surgeon can’t operate but could teach = NOT disabled
Benefit	Only if you can’t do any work at all
Cost	Cheapest
Avoid	Too restrictive

“Modified Own Occupation” (Common)

Feature	Details
Definition	Own occupation for 2-5 years, then any occupation
Example	Covered for your job initially, then must retrain
Benefit	Balance of coverage and cost
Cost	Moderate
Common in	Employer group plans

Coverage Amount: How Much Do You Need?

Standard Coverage Guidelines

Source	Coverage Amount
Employer group LTD	50-60% of base salary
Individual policy	Up to 60-70% of gross income
Combined maximum	Typically 70-80% of pre-disability income

Why Not 100%?

Reason	Explanation
Moral hazard	Incentive to return to work
Work expenses	You save on commuting, work clothes, meals
Tax treatment	Benefits may be tax-free (see below)

Tax Treatment of Benefits

Who Pays Premium	Are Benefits Taxable?
Employer pays	Yes, fully taxable
You pay with pre-tax $	Yes, fully taxable
You pay with after-tax $	No, tax-free

After-Tax Comparison

Scenario	Monthly Benefit	Tax	Net Benefit
Employer-paid, 60%	$5,000	22%	$3,900
You-paid, 60%	$5,000	$0	$5,000

Insight: A 60% benefit you pay for personally equals ~77% effective coverage due to tax-free status.

Key Takeaways

1 in 4 workers will have a disability — It’s more common than you think
Long-term disability is essential — More important than short-term
Definition matters most — Get “own occupation” if possible
Pay premiums with after-tax dollars — Benefits become tax-free
Employer coverage usually isn’t enough — Supplement with individual policy
SSDI is a safety net, not a solution — Benefits are low and hard to get
