Most people protect their home and their car and never insure the thing that pays for both: their income. Disability insurance does that. If illness or injury keeps you from working, it replaces a portion of your paycheck so your household keeps running while you recover.
Why income is the asset
Think about what your earning ability is worth over a career; for most people it dwarfs the house and the cars. Yet a disabling event during working years is more common than people expect, and when income stops, savings drain fast while the bills do not pause. Disability insurance turns that risk into a manageable plan.
Short-term and long-term
Short-term disability bridges the first weeks to a few months after a disabling event. Long-term disability picks up after that and can pay for years or to retirement age. Long-term is the more important protection for most people, because it covers the serious, lasting situations savings cannot absorb. Many households want both.
The terms that decide whether it pays
Three terms matter most. The definition of disability sets the bar: own-occupation pays if you cannot do your specific job, while any-occupation only pays if you cannot do any suitable work. The elimination period is the waiting time before benefits begin. The benefit period is how long payments last. Two policies with the same monthly benefit can differ enormously on these terms, which is why reading them, not just the price, is essential.
Why work coverage is not enough
Group disability through an employer helps, but it is often limited: it may replace less income, use a stricter definition, and disappear if you change jobs. An individual policy supplements it, stays with you, and can be structured to your actual need.
A coverage review sizes the benefit to your income and checks the definition and terms that decide whether a claim is paid.
