Most high earners are underinsured, and the reason is a single wrong assumption: that disability insurance replaces a flat 60 percent of income. It does not work that way. Carriers issue a maximum dollar benefit set by your documented income, and for a high earner that maximum is a substantial monthly figure worth securing in full. Any number here is illustrative; a current quote against your income is the only reliable read on your specific limit.
Sizing coverage correctly means starting from two anchors: the maximum dollar benefit the carriers will issue, which sets your ceiling, and your real obligations, which set your floor. The job is to secure as much of that ceiling as your income supports and to structure it so it actually pays.
Is the Benefit a Flat Percentage of Income?
No. Carriers set the maximum individual benefit as a dollar figure, using issue and participation schedules tied to your income. The major carriers track these closely, so the figures below are a reasonable carrier-agnostic read as of 2026. The maximum rises with income:
| Annual income | Maximum individual benefit (2026 issue limits) |
|---|---|
| $200,000 | ~$9,500 / month |
| $210,000 | ~$10,000 / month |
| $265,000 | ~$12,400 / month |
| $300,000 | ~$13,300 / month |
| $350,000 | ~$15,000 / month |
| $500,000 | ~$16,900 / month |
The number to anchor on is the dollar maximum for your income, not a percentage rule of thumb. The most a single carrier will typically issue tops out around $20,000 a month for the highest earners in the strongest occupation classes, and the exact ceiling moves with your state and specialty; larger total benefits are sometimes possible by combining carriers. Physicians, whose income often runs past a single carrier's cap, can see how this plays out in physician benefit sizing. Anyone who plans on a flat 60 percent will misjudge their protection, because carriers issue a specific maximum benefit and then the contract structure decides how much of it actually reaches you in a claim. That percentage rule is one of the disability insurance myths high earners fall for most often. Securing that maximum is the first move; structuring it is the second.
How Do You Size Your Own Benefit?
Work from two numbers. The ceiling is the income-based maximum from the schedule above, confirmed by a real quote against your documented income. The floor is your essential monthly spending plus fixed obligations such as a mortgage, debt service, and family support. The goal for most high earners is to secure the maximum the carriers will issue, because that maximum is the layer that protects your standard of living if your income stops.
Income documentation drives the ceiling. Carriers verify income at underwriting using tax returns and W-2s, and the benefit is sized to that documented income, so a clean, well-documented income picture is what supports the highest issuable benefit. For salaried professionals this is straightforward; self-employed and variable-income professionals should expect carriers to average across years.
Securing the maximum is only half the work. Because the benefit caps below your full income, the definition type and the residual coverage decide how much of that benefit you actually keep across a long or partial claim. A true own-occupation definition pays when you cannot perform your own occupation even if you work in another field, and residual coverage pays when a disability cuts your income rather than stopping it. Those two provisions are what make a maximum benefit hold up in practice.
How Does Group Coverage Change the Calculation?
If you have group long-term disability through an employer, factor it in before sizing individual coverage. Group plans are usually capped at $10,000 to $15,000 a month, are based on base salary only, are typically taxable when the employer pays the premium, switch from an own-occupation to an any-occupation test after roughly 24 months, and end when you change jobs. For a high earner the taxable nature matters: roughly 30 to 40 percent of a group benefit can go to tax in a top bracket, so a $10,000 group benefit nets closer to $6,000 to $7,000.
That combination, a cap, base-salary-only sizing, and tax, is why group coverage leaves a large gap for a high earner. Account for the after-tax group benefit first, then size individual coverage to close that gap up to the income-based maximum. Because individual benefits you pay for with after-tax dollars are generally tax-free, they do more work per dollar than a taxable group benefit of the same size. See group versus individual for how the two coordinate.
Do not count on Social Security to fill the remainder. Its standard is far stricter than a private own-occupation policy: under 20 CFR 404.1505, disability is "the inability to do any substantial gainful activity by reason of any medically determinable physical or mental impairment," measured against any work in the national economy. A high earner who can no longer perform their own occupation but could do other work generally will not qualify, and even an approved claim pays little against a professional income: per SSA's Monthly Statistical Snapshot, April 2026, the average disabled-worker benefit is $1,634.70 per month. That is why the income-based individual benefit, not Social Security, is the layer that has to carry the load.
What Happens as Your Income Grows?
Your benefit is sized to your income at issue, so an early-career professional whose income will climb faces future underinsurance if the benefit stays put. A future increase option addresses this by letting you raise coverage as income rises without new medical underwriting. Most new policies we place include a benefit-increase feature of this kind, and it is close to essential for anyone early in a high-growth career. It both keeps your benefit current and protects your insurability against later health changes.
How We Approach Sizing
We start by confirming your income-based ceiling across the five major carriers, because their issue and participation limits, occupation classes, and class caps differ enough to change the maximum issuable benefit. Running a case across all five is the practical advantage of an independent broker over buying direct from one carrier. Then we size and structure the benefit to your real obligations within that ceiling, document income to support the highest defensible amount, and add a future increase option where the income trajectory calls for it. The aim is to secure as much coverage as the limits allow and structure it so it pays, not to anchor on a percentage the math does not support.
To see your specific income-based maximum across all five carriers, start with a quote comparison.
