How Much Disability Insurance Do I Need?
This page will not hand you a flat percentage of income. A more useful approach starts with the obligations that would keep arriving if you could not work, then checks that figure against what your coverage would actually deliver.
Start from obligations, not a rule of thumb.
No amount, quote, or approval is promised anywhere on this page — coverage availability and cost depend on underwriting.
A common shortcut is to target a flat percentage of income, but that ignores debt structure, existing coverage, how benefits are taxed, other household resources, and the caps carriers place on total coverage. A more grounded approach compares your actual monthly obligations against what your current and available coverage would realistically deliver after any applicable taxes and waiting periods.
That comparison — obligations versus what actually reaches the household — is the gap. This page walks through how to estimate it using your own numbers, not a published statistic.
Work through the arithmetic with your own figures.
These are illustrative placeholders to show the structure of the calculation — not recommendations, averages, or typical figures.
Step 1 — List monthly obligations
Example placeholder: housing $[your figure], insurance premiums $[your figure], debt minimums $[your figure], care or dependent costs $[your figure]. Add them for a total monthly obligation figure — call it "Obligation Total."
Step 2 — Identify each coverage source's monthly benefit
Example placeholder: group plan monthly cap of $[plan figure], plus any individual policy monthly benefit of $[policy figure]. Confirm both directly from plan documents or your policy, not memory.
Step 3 — Adjust for taxation
If a benefit would be taxable, reduce the gross figure by an illustrative placeholder percentage to estimate what would actually reach the household. Confirm your own treatment with a tax professional rather than assuming either outcome.
Step 4 — Compare and note the gap
Subtract the after-tax benefit total from the Obligation Total. Add any elimination period bridge needed from savings. What remains is the gap worth discussing — not a number this page can calculate for you.
Where additional coverage could come from.
| Source | Tradeoffs to weigh |
|---|---|
| Employer group long-term disability | Often the least expensive source, but usually capped at a flat monthly benefit and may not be portable if you change jobs. |
| Individual disability income policy | Can be portable and more flexible on definitions, but subject to underwriting, cost, and carrier participation limits relative to income. |
| Association or specialty-society coverage | May offer additional capacity for certain professions, with its own terms, costs, and limits that should be read carefully. |
| Savings and emergency reserves | Can bridge an elimination period or a benefit shortfall, but is finite and may be needed for other goals at the same time. |
| A spouse's or partner's income | A real resource in many households, but should be evaluated for how reliable and sufficient it actually is, not assumed. |
Ask these before assuming a number is right.
- What is my group plan's actual monthly benefit cap, and where is that documented?
- How is each source of coverage taxed, and what would actually reach my household after tax?
- What is the elimination period on each policy, and how would we bridge it?
- What is the benefit period, and what happens if a disability lasts longer than that?
- What carrier participation limits would apply if I wanted to add individual coverage?
- If my income or job changes, does any of this coverage change or end with it?
Where the math quietly goes wrong.
- Using a flat percentage of income without checking it against actual obligations.
- Assuming a group plan's benefit equals a percentage of pay without checking the plan's actual dollar cap.
- Comparing a pre-tax benefit figure to after-tax obligations, overstating what coverage would deliver.
- Forgetting the elimination period, leaving no plan for the weeks or months before benefits begin.
- Assuming unlimited individual coverage can always be added later without underwriting or participation limits.
- Counting a spouse's income or savings without confirming those resources are actually available for this purpose.
