This is part 2 of 3 of our guide to Insurance for Individuals and Families. It picks up where Types of Personal Insurance: Health, Life, Auto and Umbrella leaves off, and it is written to stand on its own: the key ideas are restated where you need them.
Whole life is not inherently a scam — its cash-value and permanent-coverage features serve legitimate purposes in specific estate-planning situations (Part 12). But for the large majority of households whose actual need is replacing income during working years while dependents are financially reliant on them, that need has a natural expiration date, which is precisely what term insurance is priced for — paying decades of whole-life premiums for coverage needed only for two or three of those decades is a mismatch between the product and the problem.
Year one (single, no dependents): close to nothing. Nobody relies on the $75,000 income, so beyond final expenses there is no income to replace, and the group coverage many employers include is usually enough.
Year eight (Part 14.3): a partner, a new $403,200 mortgage and — assumptions added for this example — a newborn child and a partner who has left paid work to care for it, so the household again lives on one income. The DIME method adds four needs:
D — debts and final expenses: assume $10,000 (no consumer debt; card balances are paid in full each month, Part 3).
I — income: replace the earner’s take-home pay from Part 1.6: Paychecks Decoded, $2,163.60 × 26 = $56,253.60 a year, for 18 years until the child is grown. Multiplying gives $56,253.60 × 18 = $1,012,565, but a lump sum invested at the ≈4% real return from 7.1 can fund that inflation-adjusted stream for less. Present value = $56,253.60 × [1 − 1.04−18] ÷ 0.04 = $56,253.60 × 12.659 = $712,131.
M — mortgage: $403,200.
E — education: assume $100,000, an illustrative placeholder in today’s dollars.
Total = $10,000 + $712,131 + $403,200 + $100,000 = $1,225,331. Subtract existing coverage — assume employer group life of one year’s salary, $75,000 — and the need is about $1,150,000, or $1,150,331 ÷ $75,000 = 15.3 times salary. A 20- or 25-year level term policy fits the shape of that need, which is largest now and shrinks as the mortgage is paid down and the child grows up.
The 10–12× income rule exists because most people will never run a DIME calculation, and for a mid-career earner with young children and a mortgage it often lands near the right range. It assumes dependents who rely on the income for many years, modest other assets and ordinary debts. It breaks in both directions:
- Too much. A single person with no dependents (year one above) needs little; a couple near retirement with a paid-off house and large savings may need none.
- Too little. One income, young children and a new mortgage: the year-eight household in the example above needs about 15× ($1.15 million) against the $750,000–$900,000 that 10–12 × $75,000 gives.
- Double counting. DIME pays off the mortgage and also replaces full take-home pay, part of which was paying that mortgage — $2,628.56 × 12 = $31,542.72 a year (Part 14.3). Removing the overlap would lower the need, one reason to treat any formula as a starting estimate.
- What it ignores. The surviving partner’s own income, Social Security survivor benefits (Part 10.8) and existing investments each reduce the need; neither the rule nor basic DIME counts them.
Disability insurance replaces a portion of income (typically 50%–70%) if illness or injury prevents working — and the risk it covers is, for most working adults, meaningfully more likely than the risk life insurance covers. The Social Security Administration has estimated that more than one in four of today’s 20-year-olds will become disabled before reaching retirement age, yet disability coverage is bought far less often than life insurance.
Short-term disability typically covers a few months, often for common events like recovery from surgery or childbirth; long-term disability can extend for years or until retirement age; a commonly quoted rule of thumb puts an individual policy at roughly 1%–3% of annual income per year, more for riskier occupations and richer policy terms (quotes vary by insurer).
Social Security Disability Insurance is built to pay only for severe, long-lasting disability. You qualify only if your condition stops you from doing any substantial work, not just your own job; it has lasted or is expected to last at least 12 months, or to end in death; and you have waited five months, since the first benefit is paid for the sixth full month. “Substantial” means earning more than $1,690 a month in 2026 ($2,830 if blind), or $1,690 × 12 = $20,280 a year: a $75,000 earner who can still earn $21,000 at another job generally does not qualify.
Private and group policies define disability more generously. An own-occupation clause pays if you cannot perform the main duties of your regular occupation; an any-occupation clause only if you cannot do any job suited to your education, training and experience. Many policies switch from the first to the second after two years, and Social Security benefits may reduce what they pay.
Life insurance protects a family’s finances if an income disappears entirely. Disability insurance protects the far more statistically likely scenario: the income-earner is still alive, but the income stops anyway. It’s the coverage most people skip precisely because it insures against something harder to picture than death — a long, ordinary illness or injury — even though it’s the more probable event during working years.
Assume the employer’s group long-term disability plan pays 60% of salary after a 90-day elimination period: $75,000 × 60% ÷ 12 = $3,750 a month. Today the household takes home $2,163.60 × 26 ÷ 12 = $4,687.80 a month (Part 1.6: Paychecks Decoded).
If the employer pays the premium, the benefit is taxable income. On $3,750 × 12 = $45,000 a year, a single filer’s taxable income is $45,000 − $16,100 = $28,900, and federal tax is 10% × $12,400 + 12% × $16,500 = $1,240 + $1,980 = $3,220, or $268.33 a month. That leaves $3,750 − $268.33 = $3,481.67: 74% of current take-home, a gap of $1,206.13 a month. Social Security and Medicare tax also apply to employer-paid benefits for the first six calendar months after the last month worked — another $3,750 × 7.65% = $286.88 a month during that stretch. State income tax is ignored here.
If you pay the premium with after-tax dollars (or the employer adds its cost to your taxable pay), the benefit is tax-free: the full $3,750 arrives, 80% of take-home, a gap of $937.80 a month. Premiums paid pre-tax through a cafeteria plan count as employer-paid.
The elimination period pays nothing for the first 90 days. At the essential-spending level behind Part 14’s six-month emergency-fund target ($14,063.40 ÷ 6 = $2,343.90 a month), three months draw $7,031.70 from the fund — one more reason to build the full fund (1.4, 1.8: The Financial Order of Operations: Where the Next Dollar Should Go).
The gap is smaller than it looks — a disabled worker stops the 6% 401(k) deferral and most commuting costs — but it is still a gap of roughly $940–$1,210 a month for as long as the disability lasts. Where the employer offers the choice, paying the premium with after-tax dollars narrows it — you pay a little tax on the premium now so that any benefit later arrives tax-free.
The standard homeowners form, the HO-3, bundles property and liability coverage in six parts; the dwelling limit you choose sets most of the others:
| Coverage | What It Pays For | Typical Limit |
|---|---|---|
| A — Dwelling | Repairing or rebuilding the house | You choose it: the cost to rebuild |
| B — Other structures | Detached garage, shed, fence | Normally 10% of A |
| C — Personal property | Furniture, clothes, electronics | Often 50%–70% of A; low sub-limits for jewelry and firearms |
| D — Loss of use | Extra living costs while you can’t live at home | Often 20%–30% of A |
| E — Personal liability | Injury or damage you cause others, plus your legal defense | Often $100,000 minimum; $300,000–$500,000 increasingly recommended |
| F — Medical payments | Guests’ medical bills, regardless of fault | A small fixed amount |
Replacement cost vs actual cash value. Replacement cost pays to repair or replace with like materials, with no deduction for wear; actual cash value (ACV) subtracts depreciation. The standard HO-3 settles the house at replacement cost but belongings at ACV unless you add a replacement-cost endorsement (roughly 10% more premium). The house gets full replacement cost only if you insure it for at least 80% of what it would cost to rebuild.
A windstorm destroys a 15-year-old roof expected to last 20 years. A new one costs $16,000; the deductible is $1,000. At replacement cost the policy pays $16,000 − $1,000 = $15,000. At ACV, depreciating evenly, the roof is worth $16,000 × (1 − 15 ÷ 20) = $4,000, so the policy pays $4,000 − $1,000 = $3,000 and you pay the other $13,000.
Now break the 80% condition. The house would cost $350,000 to rebuild but is insured for $250,000, below 80% × $350,000 = $280,000. The policy pays the greater of ACV or a proportion of the repair: $15,000 × $250,000 ÷ $280,000 = $13,392.86, which is $1,607.14 short. Insuring for $280,000 or more removes the penalty; $350,000 also covers a total loss.
What the policy leaves out. Standard policies exclude flood and earthquake. Federal flood insurance through the NFIP covers up to $250,000 for the building and $100,000 for contents, and renters can buy contents-only coverage. A new policy generally takes effect 30 days after purchase (no wait when bought with a new or refinanced mortgage), so buy it before a storm is forecast. In hurricane-prone states, wind damage often carries a percentage deductible, typically 1%–5% of the dwelling limit: 2% of $300,000 is $6,000, not $1,000.
Renters insurance covers your belongings, your liability and your extra living costs. The landlord’s policy covers the building, not your possessions. The latest NAIC averages, for 2022, were $171 a year for renters coverage and $1,569 for an HO-3, up 11.2% in a year; a separate NAIC analysis published Aug 5, 2026 found average premiums per policy up 18.3% to 43.3% by region from 2018 to 2024 after inflation. Keep a home inventory: a dated list with prices and photos, stored off-site or online.
Claims and future price. Insurers check a database (CLUE) holding seven years of claims on you and the house. A claim can raise your premium, and repeated claims can cost you the policy: Texas, for example, lets an insurer refuse to renew after three or more non-weather claims in three years. Save the policy for losses that would hurt and pay small ones yourself. Where no company will insure a home, a state FAIR Plan sells basic coverage at a higher price.
The year-eight household (Part 14.3) gets illustrative quotes: $2,000 a year with a $1,000 deductible, $1,760 with $2,500 and $1,580 with $5,000. In 2023, 5.3% of insured homes had a claim, and the average claim paid was $20,062, far above any of these deductibles. Expected yearly cost = premium + claim frequency × deductible.
| Deductible | Premium | Expected Deductible Paid | Expected Yearly Cost | Share of the Year-One $14,063 Fund |
|---|---|---|---|---|
| $1,000 | $2,000 | 5.3% × $1,000 = $53.00 | $2,053.00 | 7% |
| $2,500 | $1,760 | 5.3% × $2,500 = $132.50 | $1,892.50 | 18% |
| $5,000 | $1,580 | 5.3% × $5,000 = $265.00 | $1,845.00 | 36% |
Break-even. Going from $1,000 to $2,500 adds $1,500 of risk per claim to save $240 a year, so it pays unless you claim more than $240 ÷ $1,500 = 0.16 times a year, once every 6.25 years: three times the average. From $1,000 to $5,000 the flip point is $420 ÷ $4,000 = 0.105, once every 9.5 years. At the average frequency the $5,000 deductible saves ($2,053 − $1,845) × 10 = $2,080 over ten years, and small claims stay off your CLUE record. It is safe only if the fund can absorb it: $5,000 plus a $1,000 auto deductible the same storm could trigger is $6,000, well inside half of even the year-one six-month fund, $14,063.40 ÷ 2 = $7,031.70; the year-eight fund, built on about $6,500 a month of essential spending (Part 14.4: Case Three — Surviving Job Loss on Three Months of Runway), is far larger.
“Insure the house for what it’s worth,” or “enough to cover the mortgage,” mixes up three numbers. The dwelling limit should match the cost to rebuild. Land doesn’t burn, and a loan is not a building. The year-eight house in Part 14.3 cost $448,000 with a $403,200 loan. If, say, $330,000 would rebuild it, a $403,200 limit buys coverage no claim can use, because the policy never pays more than the rebuilding cost. The error also runs the other way: an older house in a cheap market might sell for $200,000 but cost $300,000 to rebuild, and insuring it at market value falls below 80% × $300,000 = $240,000.

Four questions on this chapter. Decide on your answer first, then click “Reveal Answer.”
1. A 33-year-old sole earner has a newborn and a new mortgage. The need for coverage is largest now and shrinks as the mortgage is paid down and the child grows. Which policy fits that shape?
- A whole life policy, which builds cash value while it covers the need
- A 20- or 25-year level term policy sized to the calculated need
- Employer group life equal to one year’s salary, kept as it is
- A 10-year term policy, since the mortgage balance falls fastest early on
Reveal Answer
Answer: B. Income replacement has a natural end date, when the child is grown and the mortgage paid, which is what term is priced for. Whole life costs 15–20 times more, and one year’s salary covers a fraction of a roughly 15× need. (Part 8.3)
2. Your house would cost $400,000 to rebuild but is insured for $300,000. A fire causes $25,000 of damage at replacement cost, the deductible is $1,000, and the proportional payment exceeds actual cash value. What does the policy pay?
- $23,437.50
- $22,500
- $24,000
- $18,000
Reveal Answer
Answer: B. The 80% requirement is $320,000, so the policy pays ($25,000 − $1,000) × $300,000 ÷ $320,000 = $22,500. Dividing by the full $400,000 rebuilding cost gives $18,000; ignoring the condition gives $24,000. (Part 8.5)
3. After an injury, a surgeon can no longer operate but could earn about $2,500 a month teaching. Under 2026 rules, which coverage is most likely to pay?
- Social Security disability, starting in the sixth full month
- An any-occupation policy, because the surgeon’s own job is lost
- An own-occupation policy, but not Social Security disability
- Both, because the injury will last more than 12 months
Reveal Answer
Answer: C. Social Security requires that you cannot do any substantial work, and earnings above $1,690 a month in 2026 count as substantial; $2,500 is above that line. An own-occupation clause pays when you cannot do your regular occupation, while an any-occupation clause does not if another suitable job is possible. (Part 8.4)
4. Worked problem: Using the DIME method: debts $200,000, income $70,000 for 10 years, mortgage $300,000 and education $100,000. How much term life cover?
Reveal Answer
Answer: Cover = $200,000 + $700,000 + $300,000 + $100,000 = $1,300,000.
