Life insurance is a contract under which an insurer pays a tax-free death benefit to your named beneficiaries if you die while the policy is in force. The two main categories are Term life (the most affordable option, covering a fixed period) and Permanent life (Whole Life or Universal Life, which last for life and accumulate cash value). For a healthy 30-year-old non-smoker, a $500,000 20-year term policy typically costs about $15 to $30 per month in 2026.
Key Takeaways
- Most people need term, not whole life. Term insurance is pure protection at the lowest cost, while permanent policies bundle insurance with a savings component that consumers can usually outperform by investing the premium difference.
- A common rule of thumb is 10 to 15 times your annual income for the death-benefit amount, refined by dependents, debt, and college costs (the DIME formula).
- Underwriting typically requires a medical exam (paramedical visit, blood, and urine), though simplified-issue and no-exam products waive the exam in exchange for higher premiums and lower face amounts.
- Term premiums depend on age, health class, smoking status, and term length. Locking in coverage while you are young and healthy is materially cheaper than buying later.
- Death benefits are generally income-tax-free to beneficiaries under Internal Revenue Code §101, one of the most consumer-friendly tax treatments in the U.S. code.
Term vs permanent life insurance
The single most important decision in life insurance is choosing between term and permanent coverage. They solve different problems and cost dramatically different amounts.
Term life insurance covers a fixed period — most commonly 10, 15, 20, or 30 years. It is pure death-benefit protection with no savings component. If you die during the term, your beneficiaries receive the face amount; if you outlive the term, the policy expires worthless. Because the insurer is only on the hook during a defined window when you are statistically unlikely to die, term is by far the cheapest form of coverage.
Whole life insurance is permanent coverage that lasts your entire life as long as premiums are paid, and it builds a guaranteed cash value over time. Mutual insurers may also pay non-guaranteed dividends. Whole life premiums are typically 10 to 20 times more expensive than equivalent term coverage because part of every premium funds the cash-value account and lifetime guarantee.
Universal life insurance is also permanent, but offers flexible premiums and a cash value tied to current interest-rate credits (or, in indexed and variable variants, to an equity index or sub-accounts). It is more complex and carries more policyowner responsibility for keeping the policy adequately funded.
For the vast majority of consumers, the right answer is term insurance combined with disciplined investing of the premium savings. Permanent insurance generally makes sense only in specific situations: estate-tax planning for high-net-worth households, funding a special-needs trust, equalizing inheritances among heirs, or business-continuity arrangements. If those scenarios do not apply to you, term is almost always the better value.
How much life insurance do you need?
Two widely used frameworks help size your death benefit:
The income-multiple rule: Aim for 10 to 15 times your annual gross income. A household earning $100,000 would target $1 million to $1.5 million in coverage. This is a quick starting point, not a precise answer.
The DIME formula is more precise and adds up four categories:
- D — Debt: All non-mortgage debt (credit cards, auto loans, student loans, personal loans).
- I — Income replacement: Annual income multiplied by the number of years your dependents will need support (often 10 to 20 years).
- M — Mortgage: The full outstanding balance on your primary residence.
- E — Education: Projected college costs for each child.
Refine the result for your specific situation: the number and ages of dependents, your spouse’s earning capacity, existing investment and retirement assets, expected Social Security survivor benefits, and end-of-life and funeral costs (often $10,000 to $20,000).

How to compare life insurance carriers
Once you know the type and amount of coverage you need, evaluate carriers and policies on these six criteria:
- A.M. Best financial strength rating. Choose carriers rated A (Excellent) or better. Life insurance is a multi-decade promise, and the insurer’s solvency matters more than a few dollars of monthly savings.
- Term length matched to your need. If your youngest child is 2 and you want coverage through college graduation, a 20-year term aligns to that risk window. Mismatched terms force you to re-shop at older ages and higher prices.
- Conversion privilege. A good term policy lets you convert to a permanent policy from the same insurer without new medical underwriting, locked in at your original health class, within a defined window (often the first 10 years or up to a certain age).
- Riders. Look for a waiver-of-premium rider (waives premiums if you become disabled), an accelerated death benefit rider (allows access to part of the benefit if diagnosed terminally ill), and a robust term conversion rider.
- Price for your exact health class. Quotes shown in advertising are almost always for Preferred Plus, the best class. Your real price depends on the class you are assigned after underwriting — get quotes that reflect your honest health profile.
- Simplified-issue vs fully-underwritten trade-off. Fully underwritten policies require an exam but offer the lowest premiums. Simplified-issue and no-exam products approve faster (1 to 7 days vs. 2 to 8 weeks) but cost more and cap face amounts.

The underwriting process
Traditional fully-underwritten life insurance follows a defined sequence:
- Application. You complete a detailed application covering personal information, occupation, hobbies, finances, and beneficiaries.
- Medical questionnaire. A telephone or online interview captures health history, family history, and lifestyle factors.
- Medical exam. A paramedical examiner visits your home or office to record height, weight, blood pressure, and a blood and urine sample. For older applicants or larger face amounts, an EKG and additional bloodwork may be required.
- MIB and prescription database check. The insurer queries the Medical Information Bureau (MIB) for prior life-insurance application history and pulls your prescription history from industry databases.
- Prescription and motor-vehicle records. Rx history flags conditions; a DMV check surfaces moving violations and DUIs.
- Health class assignment. Based on all of the above, you are placed into a class: Preferred Plus, Preferred, Standard Plus, Standard, Substandard (Table A through J), or Tobacco. Each step down the ladder increases your premium.
- Premium quote and policy issue. The insurer offers a final premium; you accept, pay the first premium, and the policy is placed in force.
The full timeline for traditional underwriting runs 2 to 8 weeks. Simplified-issue and accelerated underwriting programs use data sources in place of an exam and can issue coverage in 1 to 7 days, with a premium markup and typically a $1 million to $3 million face-amount ceiling.

Frequently asked questions
Term vs whole life — which is better?
Term life is the better choice for the vast majority of consumers. It delivers the death-benefit protection your family needs during the years you have dependents at the lowest possible cost — typically 10 to 20 times cheaper than equivalent whole life. Whole life makes sense only in specific situations such as estate-tax planning for high-net-worth households, funding a special-needs trust, or business-continuity arrangements.
How much life insurance do I need?
A common rule of thumb is 10 to 15 times your annual gross income. For a more precise figure, use the DIME formula: add up your non-mortgage Debt, Income replacement (annual income times the years of support needed), Mortgage balance, and Education costs for your children. Adjust for your spouse’s earning capacity, existing investments, and expected survivor benefits.
Is the life insurance death benefit taxable?
No. Under Internal Revenue Code §101, life insurance death benefits paid to a named beneficiary because of the insured’s death are generally excluded from the beneficiary’s gross income for federal tax purposes. Exceptions exist — for example, when a policy is transferred for value or when the proceeds are paid as interest over time — but the core death benefit is one of the most tax-favored payments in the U.S. code.
Do I need a medical exam for life insurance?
It depends on the policy size, your age, and the carrier’s underwriting program. Traditional fully-underwritten policies require a paramedical exam with blood and urine samples to qualify for the best rates. Simplified-issue and accelerated-underwriting programs can waive the exam by relying on prescription, MIB, and motor-vehicle data — usually in exchange for higher premiums and a cap on face amount.
When should I buy life insurance?
Buy life insurance when other people depend on your income or unpaid labor. The classic triggers are marriage, having a child, or taking on a mortgage. Premiums rise with age and with new diagnoses, so locking in coverage while you are young and healthy materially lowers your lifetime cost.
Can I convert term life insurance to permanent?
Most term policies include a conversion privilege that lets you switch to a permanent policy from the same insurer within a defined window — often the first 10 years of the policy or up to a specific age such as 65 or 70 — without new medical underwriting. Your original health class is preserved, which is valuable if your health has deteriorated since you first qualified.
What is “cash value” in life insurance?
Cash value is the savings component built into permanent life insurance policies (whole life and universal life). A portion of every premium funds the cash-value account, which grows on a tax-deferred basis. You can borrow against it through a policy loan or surrender the policy for its cash value, though loans accrue interest and unpaid balances reduce the death benefit.
Does life insurance cover suicide?
Most life insurance policies include a two-year contestability and suicide-exclusion period beginning at policy issue. If the insured dies by suicide within those first two years, the insurer typically refunds premiums paid rather than the full death benefit. After the two-year window closes, suicide is generally covered the same as any other cause of death.
