Disability insurance
Your ability to earn is your largest asset for most of your life. This is the policy that insures it, and most people either skip it or hold a version that will disappoint them.
A plain-language reference, not advice. Describes how long-term disability insurance works and why it is under-bought, with policy features to look for. Statistics on disability incidence are deliberately omitted pending a sourced figure. Employer plans and individual policies vary; read the actual contract.

The risk almost nobody insures properly
Ask people whether they have life insurance and most working parents say yes. Ask whether they have disability insurance and you get a pause. Yet for a working-age adult the odds of a long absence from work due to illness or injury are meaningfully higher than the odds of dying, and the financial consequence is arguably worse: you are still here, still have expenses, may have new medical ones, and the income is gone. Your ability to earn is your largest asset for most of your life. This is the policy that insures it.
Short-term versus long-term
Short-term disability covers weeks to a few months, often through an employer, and overlaps heavily with what an emergency fund is for. It is nice to have. Long-term disability — the subject of this guide — picks up after an elimination period of a few months and can pay until retirement age. That is the coverage that matters, because a multi-year or permanent loss of income is the scenario a family cannot self-insure.
Why it is under-bought
Three reasons, roughly. It is not top of mind the way death is. Employer coverage creates a false sense of adequacy. And it is genuinely more complicated to buy than term life, with more moving parts in the contract and more ways for a policy to disappoint you at claim time. That last point is the whole reason to read the next section.
The features that decide whether it pays
Definition of disability. The single most important clause. Own-occupation pays if you cannot do your specific job; any-occupation pays only if you cannot do any job you are reasonably suited for. A surgeon with a hand tremor is disabled under the first and possibly not under the second. Many employer policies start as own-occupation and convert to any-occupation after two years. Read which one you have.
Benefit amount. Typically capped at a percentage of income, often around 60 percent, sometimes with a dollar ceiling that high earners hit. Note whether the benefit is taxable: if your employer pays the premium, benefits are usually taxed; if you pay with after-tax dollars, they are usually not. That difference can be a third of the cheque.
Elimination period. How long you wait before benefits begin. Longer means cheaper; your emergency fund should be sized to cover it.
Benefit period. How long it pays. To age 65 or 67 is the standard for real protection; two- or five-year caps are much weaker than they sound.
Non-cancellable and guaranteed renewable. The insurer cannot cancel or raise premiums as long as you pay. Worth having.
Riders. Cost-of-living adjustments on benefits; future-increase options that let you raise coverage as income grows without new medical underwriting; partial or residual benefits for reduced capacity. Useful for younger professionals with rising income.
Employer coverage: the fine print
Group long-term disability is a good start and often the only affordable option for some. But it usually pays a modest percentage of base salary (not bonuses), is taxable, may switch to any-occupation after two years, and ends when you leave the job. If your household depends on your income, an individual policy layered on top — or instead — is the standard recommendation, especially for people whose skills are specific and whose earning power is high.
Social Security disability
Exists, is hard to qualify for, pays modestly, and takes a long time to approve. Treat it as a backstop of last resort, not a plan.
Who especially needs it
Anyone whose household would be in trouble within a few months of their paycheque stopping. Self-employed people, who have no employer coverage at all. Professionals with specialised skills and high income relative to assets — the gap between what they earn and what they have saved is exactly the exposure. Younger workers, who have the most earning years ahead and the least saved.
