Insurance is one of the most-skipped financial-planning steps because the math is unpleasant: you pay premiums for coverage you hope to never use. But the unhedged version of "I'll skip this" is "if X happens, I lose the plan." This article walks you through a decision tree that surfaces the gaps most working-age households actually have.
We're focused on personal coverage — life, disability, health, long-term care, umbrella. (Auto and home are usually adequately covered through normal channels; the gap there is mostly umbrella.)
The 3-question test for any policy
Before deciding which insurance to buy, run the policy through three questions:
What event are we protecting against? (Death, disability, hospitalization, lawsuit, lawsuit, lawsuit.)
What does that event cost in dollars if it happens? (Lost income for X years, $200k of medical bills, $2M lawsuit verdict.)
Could I absorb that cost from savings? (If yes, you don't need the insurance. If no, you do.)
If the answer to (3) is "no" and the premium is reasonable relative to (2), buy the coverage. If the answer is "yes," you're "self-insuring" — also fine.
Decision tree
Walk through each branch in order.
1. Health insurance
Do you have employer or marketplace coverage?
Yes — confirm in-network providers cover your area, max out-of-pocket is under ~$10k/yr, and an HDHP+HSA is available if you're healthy. Done.
No — buy from the ACA marketplace immediately. Even bronze plans cap your annual exposure at the federal out-of-pocket max (~$9,500 in 2026). The "I'll just pay cash" plan is mathematically broken — a single surgery wipes most retirement accounts.
This is the only coverage where not buying is genuinely irrational for almost everyone.
2. Life insurance
Does anyone depend on your income? (Spouse, kids, dependent parents.)
No — skip life insurance. Funeral costs are real but coverable from savings.
Yes — go to the next question.
How many years until your dependents could replace your income themselves?
<5 years — small term policy ($250k–$500k) for funeral + transition.
5–25 years — substantial term policy. Common rule of thumb: 10–12× annual income. The Horizons insurance analyzer computes this from your specific numbers.
25+ years (parent of young kids) — 12–15× income, 20–30 year term.
Term or permanent?
Default = term. Cheaper, simpler, matches the period your dependents need protection.
Permanent only if you have estate-tax exposure (unlikely under the current $15M exemption) OR a special-needs dependent who'll need lifetime support OR a business buy-sell agreement that needs funding.
A 35-year-old non-smoker can typically get a 20-year, $1M term policy for $25–$40/month. A 35-year-old buying $1M of whole life pays $700+/month for the same death benefit. The spread is the cost of the savings component bundled in — and you can almost always invest the difference more efficiently yourself.
3. Disability insurance
Do you have employer LTD coverage?
No — buy a private LTD policy that pays at least 60% of income. This is the most-underweighted coverage in personal finance.
Yes — what's the benefit amount and who pays the premium?
Premium paid by employer → benefit will be taxable when paid out (rule: tax follows the premium dollar)
Premium paid by you (post-tax) → benefit tax-free
If your benefit minus tax is <60% of after-tax income, supplement with a private policy
Disability is statistically more likely than premature death for working-age adults. The Horizons insurance analyzer computes a target monthly benefit and the gap between it and your existing coverage.
4. Umbrella liability
Net worth above $500k OR significant exposure (rental property, teen drivers, swimming pool, dog, frequent guests)?
Yes — buy an umbrella policy of at least 1× net worth (commonly $1M–$3M). Annual premium is usually $200–$500 for $1M of coverage. This is the cheapest insurance in the entire personal-finance toolkit relative to what it protects against.
No — your home + auto liability limits are probably enough. Re-check at every net-worth doubling.
Umbrella is asymmetric: low premium for protection against a one-shot event (lawsuit, accident) that could otherwise wipe you out. Almost nobody who has it ever uses it; the few who do are very glad they did.
5. Long-term care
Are you over age 50 or have a family history that suggests long-term care needs?
Under 50 — wait. Premiums spike with age but quality coverage is overpriced before 50.
50–65 — evaluate now. Either traditional LTC (cheaper but use-it-or-lose-it) or hybrid life-LTC (more expensive but the unused premium goes to heirs).
Over 65 with no LTC — you may not qualify for new policies. Self-funding from a designated portfolio is the realistic path.
LTC is the hardest coverage decision because it sits at the crossroads of "you might never use it" and "if you use it, it's catastrophic" and "if you wait too long, you can't get it." The Horizons LTC modeling pages walk through specifics; this article only gates whether you should think about it.
6. Auto + home
Standard coverage with a major carrier?
Yes — done. Verify your liability limits aren't the state minimum. Bump them to $500k each if cheap.
No (rare) — fix this before next month's premium.
The umbrella step (#4) handles excess liability beyond auto/home limits.
When to re-run this tree
Annually as part of an insurance review
Within 30 days of: marriage, divorce, new child, job change, home purchase, business sale, retirement
After any net-worth jump of ≥30% (umbrella may need to grow)
What this tree doesn't cover
Disability for the self-employed — different rules; most existing employer-LTD math doesn't apply. Talk to a fee-only insurance specialist.
Group life through employer — usually too small to count toward your real coverage need; treat it as a small bonus, not the plan.
Permanent life as an estate-planning tool — only relevant for estates above the federal exemption ($15M per person in 2026). If you're there, this article isn't your right starting point.
Long-term care via Medicaid — possible but requires asset spend-down. Out of scope here.
The goal is coverage where you can't self-insure against the loss, at the cheapest premium that delivers the coverage. The Horizons insurance analyzer computes the dollar gaps from your specific profile; this article is the framework for interpreting the answer.
