Term Life Insurance Explained: How Much Coverage, For How Long, and Why Term Usually Wins
August 17, 2026 · Guides · 12 min read
Life insurance is one of the few financial products where the right answer for most households is both cheap and boring: a level term policy, sized to actual obligations, lasting until those obligations end. The reason the product feels complicated is that the version that is simple to explain is also the version that pays the smallest commission.
This guide covers who needs coverage at all, how to size it from real numbers, why term and permanent policies differ so much in price, and the narrower set of situations where permanent coverage genuinely earns its cost.
Who Needs It
Life insurance exists to replace financial dependency. The test is narrow: if you died tomorrow, would someone suffer financially? If yes, coverage is warranted for as long as that dependency lasts.
That framing rules cases in and out cleanly:
Warranted: a household where one income supports a partner or children; a stay-at-home parent whose unpaid labor would have to be replaced with paid childcare; a co-signer on a mortgage that a survivor could not service alone; a business owner whose death would trigger a buy-sell obligation or a personally guaranteed loan.
Usually not warranted: a single adult with no dependents and no co-signed debt; a retired couple whose assets already cover the survivor's needs; a child. Insurance on a child's life is frequently sold and rarely defensible — a child produces no income to replace, and the argument for it is usually about future insurability, which is a small benefit at a high price.
Federal student loans are discharged at death. Private student loans may not be, and a co-signer can be pursued — worth checking the actual loan terms rather than assuming either way.
Sizing the Death Benefit
The common shortcut is "10 to 12 times income." It is a starting point, not a calculation, and it is wrong in both directions depending on circumstances — too high for a household with a paid-off house and nearly grown children, too low for a young family with a large mortgage and a decade of childcare ahead.
The better method builds the number from what the money actually has to do. A common structure, sometimes taught as DIME:
Debt. All non-mortgage debt that would survive: credit cards, car loans, private student loans with a co-signer, personal loans. Plus final expenses — a funeral commonly runs $8,000 to $15,000.
Income replacement. The gap between the survivor's income and the household's needs, multiplied by the number of years it must be covered. For a household needing $85,000 a year with a surviving partner earning $50,000, the gap is $35,000 a year. Covering it for 18 years is $630,000 in today's dollars — though see the note on lump sums below.
Mortgage. The outstanding balance, if the intent is for the survivor to own the home free and clear. Some households instead cover only enough to keep payments manageable, which is a smaller number.
Education. Projected costs for each child, if funding it is part of the obligation.
Then subtract existing resources: current savings and investments, existing group coverage through an employer, and any Social Security survivor benefits, which are substantial for a widow or widower with children under 16 and often overlooked entirely in this calculation.
A worked example
A household with two earners, ages 36 and 34, two children aged 4 and 7:
| Component | Amount |
|---|---|
| Mortgage balance | $310,000 |
| Other debt (auto, cards) | $28,000 |
| Final expenses | $15,000 |
| Income replacement ($35,000 × 18 years) | $630,000 |
| Education (2 children) | $200,000 |
| Subtotal need | $1,183,000 |
| Less: existing investments | −$145,000 |
| Less: employer group coverage (2× salary) | −$170,000 |
| Coverage gap | $868,000 |
Round to $900,000 of term coverage on the higher earner. A shorter, smaller policy on the lower earner covers the childcare replacement cost if that person dies.
Two refinements worth knowing. First, a lump sum invested generates returns, so the strict present value of an 18-year income stream is less than 18 × the annual gap — which argues for a somewhat smaller figure. Second, inflation raises the nominal gap each year, which argues for a larger one. These partly offset, and the unadjusted sum is a reasonable middle.
Why Term Costs So Little
Term life covers a fixed period — 10, 15, 20, or 30 years — at a level premium, and pays only if death occurs during that window. Most term policies expire without paying anything, which is precisely why they are cheap. The insurer is pricing a genuinely low probability.
Permanent life (whole life, universal life, variable universal life) covers the entire lifespan and accumulates a cash value. Because a permanent policy is certain to pay eventually, the insurer must fund the full death benefit — so the premium is dramatically higher and part of it goes into the cash value account.
The price difference is not subtle. A healthy 35-year-old non-smoker might pay somewhere in the range of $40 to $70 a month for $1,000,000 of 20-year level term. Comparable permanent coverage frequently runs ten to fifteen times that. Actual quotes vary substantially with health, state, carrier, and underwriting class, so those figures are illustrative of the ratio rather than a quote.
This gap is the entire basis of the "buy term and invest the difference" argument. Purchasing term coverage and directing the premium difference into a tax-advantaged account will, under most return assumptions, produce more wealth than the cash value accumulation inside a permanent policy — which typically carries higher internal costs and takes many years to break even. The argument has one real weakness: it depends on the difference actually being invested rather than spent, and many households do not invest it.
Where Permanent Coverage Earns Its Cost
Term is the default, not a universal answer. Permanent coverage has legitimate uses:
A lifelong dependent. A child with a disability who will require support after both parents die creates a need that never terminates. A term policy expiring at 65 does not address it.
Estate liquidity. With a 2026 federal estate tax exclusion of $15,000,000 per person, federal estate tax affects very few households — but several states impose their own estate or inheritance tax at far lower thresholds. Where an estate is concentrated in illiquid assets (a farm, a closely held business, real estate), a permanent policy can supply cash to pay the tax without a forced sale.
Business continuity. Buy-sell agreements funded with life insurance, and key-person coverage, are ordinary commercial arrangements with no term equivalent, since the need does not have a known end date.
A specific charitable or legacy intent where a guaranteed payout at an unknown date is the actual goal.
What is generally not a good reason: using permanent life insurance as a primary retirement savings vehicle. The internal costs are high relative to tax-advantaged retirement accounts, and the ordering in the financial order of operations puts a 401(k), HSA, and IRA well ahead of it.
Choosing the Term Length
The term should outlast the obligation. Working backward from the sizing exercise:
- Until the youngest child is financially independent. For a household with a 4-year-old, that is roughly 18 to 22 years, pointing to a 20- or 25-year term.
- Until the mortgage is retired. A 30-year mortgage taken this year points toward a 30-year term.
- Until retirement assets are sufficient. Once the portfolio can support the survivor, the dependency ends.
A common structure is laddering: stacking two or three policies with different end dates so coverage declines as obligations do. A $500,000 30-year policy plus a $400,000 15-year policy costs less than $900,000 for 30 years and matches the actual shape of the need, since the childcare-and-education component ends long before the mortgage does.
Level term versus decreasing term: level term keeps the death benefit constant; decreasing term reduces it over time, notionally tracking a mortgage balance. Level term is usually the better structure — it costs little more and does not assume the mortgage is the only obligation.
Riders and Features Worth Understanding
Convertibility. The right to convert a term policy to permanent coverage without new medical underwriting, up to a stated age. This is the most valuable rider on most term policies and often costs nothing. It functions as an option on future insurability — if a serious diagnosis arrives during the term, the conversion right preserves access to coverage that new underwriting would deny.
Waiver of premium. Premiums are waived if the insured becomes disabled. Modest cost, meaningful protection, since disability and the inability to pay premiums arrive together.
Accelerated death benefit. Access to part of the death benefit on a terminal diagnosis. Frequently included at no additional charge.
Return of premium. Refunds premiums if the insured survives the term. It sounds appealing and is generally poor value — the additional premium, invested instead, typically exceeds the refund, and the refund is an interest-free loan to the insurer in the meantime.
Employer Group Coverage
Most group life insurance through an employer provides one to two times salary, often free. Three limitations matter:
- It is rarely enough. Two times salary against the $868,000 gap in the example above covers a fraction.
- It is not portable. It typically ends at termination. Conversion options exist and are usually expensive.
- It ties coverage to employment — the same event, a layoff, removes both the income and the insurance.
Group coverage is a supplement. The core policy is generally best held individually, where it is portable and permanently priced at the health status at issue.
Underwriting, Briefly
Premiums are set by health class, and the spread between classes is large — a preferred-plus rating can cost half of a standard rating for the same coverage. Underwriting considers age, tobacco use (including cigars and nicotine replacement, which many applicants do not realize is tested), height and weight, blood pressure and cholesterol, family history, prescriptions, driving record, and hazardous activities.
Two practical points. Coverage priced at a younger age stays at that price for the whole level term — a 20-year policy purchased at 32 costs meaningfully less than the same policy purchased at 38, permanently. And no-exam policies trade convenience for price: they use algorithmic underwriting and are usually more expensive for a healthy applicant than a policy with a paramedical exam.
Material misstatements on an application matter. Most policies carry a two-year contestability period during which the insurer can investigate and deny a claim for misrepresentation. Suicide exclusions typically run two years as well.
Frequently Asked Questions
Does a stay-at-home parent need coverage? Frequently yes. The economic loss is the cost of replacing unpaid labor — childcare, transportation, household management — which can run tens of thousands of dollars a year for a household with young children. The death benefit is generally smaller than for the earning partner, but it is rarely zero.
Is mortgage protection insurance worth it? It is a decreasing-term policy that pays the lender rather than the family, usually at a worse price than an equivalent term policy the household controls. A larger level term policy naming the survivor as beneficiary generally provides more flexibility for less money.
What happens at the end of the term? The policy either ends or continues at a sharply increased annual renewable rate that rises every year. Most policyholders let it lapse, which is the intended outcome if the obligation has ended. Where the need persists, converting before the conversion deadline (often earlier than the term's end) preserves options.
Are death benefits taxable? Life insurance death benefits are generally received income-tax-free by the beneficiary. They may still be included in the taxable estate if the insured owned the policy, which is why irrevocable life insurance trusts exist for larger estates. Interest paid on delayed settlement is taxable.
How does this interact with disability coverage? Disability is statistically the more likely event during working years and is more often uninsured — covered in disability insurance explained. A household with substantial life coverage and no disability coverage has usually insured the less likely risk.
