Starting Out

Disability Insurance: The Coverage Most People Skip That They Need Most

Most people insure their car, home, and even their life. They don't insure their most valuable financial asset: their income. A 30-year-old has a 1-in-4 chance of being disabled for 90+ days before age 65. Without disability insurance, one health event ends your income — and most families are one paycheck from financial collapse.

The employer group LTD problem

Most employer LTD policies have features that sound good but severely limit protection:

Own-occupation vs. any-occupation is the most important distinction in disability insurance. "Own-occupation" pays if you can't perform the duties of your specific occupation — even if you could theoretically work in another role. This is the gold standard and is critical for high-income professionals (physicians, dentists, attorneys, engineers). "Any-occupation" is significantly weaker — and what most employer group policies use after 24 months.

How much individual disability coverage to buy

Target: 60–70% of your gross income in total disability income (employer LTD + individual policy). Steps:

  1. Calculate 60% of your monthly gross income
  2. Subtract your employer LTD benefit (check your benefits summary)
  3. The gap is the target benefit amount for an individual policy
  4. Your emergency fund determines your elimination period — 90 days if you have 3+ months saved; 60 days if less

Example: $120,000 annual income. 60% = $6,000/month target. Employer covers $4,500/month. Individual policy needed: $1,500/month.

What disability insurance costs

ProfileMonthly BenefitMonthly PremiumAnnual Cost
35yr male, office work, to age 65$3,000/mo$75–$120/mo$900–$1,440
35yr female, office work, to age 65$3,000/mo$100–$160/mo$1,200–$1,920
40yr physician, own-occ, to age 65$10,000/mo$400–$700/mo$4,800–$8,400

Women pay more — statistically higher claim rates. Occupation class matters significantly — manual labor classes cost more than office work. The best time to buy: when you're young and healthy. Premiums lock in at purchase; health deterioration later can't raise existing policy rates.

The risk is larger than people assume

Working-age adults are considerably more likely to face a spell unable to work than to die during their career, yet life cover is bought far more often. Most long-term absence is caused not by accidents but by ordinary conditions — musculoskeletal problems, cancer, cardiovascular disease and mental health — which is precisely why it is easy to discount.

Your income is the asset every other plan rests on. Insuring the house and not the thing that pays for it is the more common gap.

The definition is the policy

One clause matters more than price, and it is where cheap policies are cheap.

Some policies are own-occupation for an initial period and then switch. Check which you are buying, and when it changes.

The other terms that decide what you get

How the benefit is taxed

This decides how much cover you need, and it turns on who pays the premium. Where you pay from after-tax income the benefit is generally received tax-free; where an employer pays, the benefit is usually taxable. A taxable benefit of 60% of salary is worth far less than a tax-free one, so the two are not comparable at face value.

Insurers also cap cover at a proportion of earnings — commonly 50–70% — deliberately, so that returning to work always pays more than claiming.

Before buying

  1. Find out what you already have. Employer group cover, and any state provision. Group cover is cheap but ends with the job and is often any-occupation.
  2. Disclose fully. Non-disclosure is the main reason claims are declined, and it surfaces years later when the claim is made.
  3. Buy young if you will buy at all. Premiums are priced on age and health at inception, and a condition acquired in the meantime is excluded.

Frequently asked questions

What is the difference between own-occupation and any-occupation cover?
Own-occupation pays if you cannot do your job. Any-occupation pays only if you cannot do any job you are reasonably suited to. A surgeon who loses fine motor control is covered by the first and may receive nothing under the second. Some policies switch from one to the other after an initial period.

How much disability cover do I need?
Insurers typically cap cover at 50-70% of earnings, deliberately, so returning to work always pays more than claiming. How much you need depends on tax: where you pay the premium from after-tax income the benefit is generally tax-free, and where an employer pays it is usually taxable.

What is a deferred period?
How long you wait before payments start, typically 4 to 52 weeks. A longer wait cuts the premium sharply and has to be matched against your emergency fund and any employer sick pay.

Why are disability claims declined?
Non-disclosure is the most common reason, and it surfaces years later when you claim. Disclose fully at application, and buy young if you intend to buy at all — premiums are priced on age and health at inception, and any condition acquired later is excluded.
