The short answer
Aim to replace enough of your income to cover your essential expenses if you could not work — generally your take-home pay rather than your gross salary. Insurers typically cap disability coverage at around 60 percent of gross income, partly because benefits from a policy you pay for are usually tax-free, so a capped benefit often lands close to your actual take-home. The goal is a benefit that keeps your household running without needing to work.
So the sizing target is your real cost of living, and the tax-free nature of most individual benefits helps a capped amount go further than it looks.
Why insurers cap replacement
Insurers limit how much of your income you can replace — usually to roughly 60 percent of gross — to preserve your incentive to return to work. Because benefits from an individual policy you paid for with after-tax dollars are generally received tax-free, that 60 percent of gross can approximate your take-home pay. Understanding this helps you avoid the mistake of thinking you are badly underinsured when a capped benefit may actually cover your needs. Our foundational guide to what disability insurance is covers the basics these caps build on.
The cap is deliberate, and its interaction with the tax treatment is why the coverage still works despite not replacing 100 percent.
How riders close the gap
If the standard cap leaves a shortfall, certain riders help: a cost-of-living adjustment rider keeps your benefit rising with inflation during a long claim, and a future-increase option lets you buy more coverage later as your income grows without new medical underwriting. These preserve the real value of your benefit over time. Our guide to own-occupation coverage covers the other clause that shapes what you collect.
The takeaway: size disability coverage to your take-home needs, expect a cap around 60 percent of gross, and use riders to protect the benefit's value over time.
