Why disability insurance

Reviewed by licensed advisors, CLU®, ChFC®Last reviewed September 2026

Direct answer

For most high earners, future income is the largest asset they own, and the one least likely to be insured properly. Disability insurance replaces part of that income if illness or injury stops you from working in your field. The question is not whether to have it, but how much, under what definition, and from whom.

The evidence

Each figure links to its primary source. We update them when the source does.

Your career is the asset

A 35-year-old earning $350,000 will earn roughly $18 million before 67 with modest raises. Most people insure their house, car, and life, and leave the $18 million uninsured or covered by a capped employer plan they have never read.

Use the calculator to see your own figure, then check how much of it your current plan would replace.

Five things people get wrong

AssumptionWhat the contract says

My hospital plan covers me.

It covers 60% of base salary up to a cap, usually $10,000 to $15,000, before tax. Bonus and call pay are rarely counted. It ends when you leave.

Social Security will pay if I really cannot work.

SSDI requires inability to do any substantial work, pays a maximum near $3,800 per month in 2026, and denies most first applications.

I am healthy, so I can wait.

Premiums rise with age and any diagnosis can add an exclusion or a decline. The cheapest policy you will ever buy is the one you buy this year.

All own-occupation policies are the same.

Some stop paying when you take other work. Some switch to any-occupation after 24 months. The difference is in one sentence of the contract.

An advisor will push the most expensive option.

Prices are set by carriers and are identical whether you buy direct or through an independent advisor. Compensation is disclosed on this site.
