Life Insurance: Term vs. Permanent — Which Do You Need?

Why Life Insurance Matters

Life insurance exists for one fundamental reason: to replace the financial contribution you make to the people who depend on you. If you died tomorrow, could your family maintain their standard of living? Could they pay the mortgage, fund college, cover daily expenses, and eventually retire on their own? For most working adults with dependents, the answer is no — and that is precisely the gap life insurance is designed to fill.

Beyond income replacement, life insurance serves several other important functions. It can cover outstanding debts so your family is not burdened with a mortgage, car loans, or student loans. It can fund your children’s education. It provides liquidity to pay estate taxes or settle business obligations. And it offers peace of mind — the knowledge that your family will be financially secure regardless of what happens to you.

How Much Coverage Do You Need?

There are two common approaches to determining the right amount of life insurance coverage.

The income replacement method is a quick rule of thumb: multiply your annual gross income by 10 to 15. A person earning $100,000 per year would need $1 million to $1.5 million in coverage. This method is simple but does not account for your specific financial situation.

The needs-based method is more precise. It involves calculating the total financial obligations your family would face without your income: outstanding debts (mortgage, loans), annual living expenses multiplied by the number of years your dependents need support, college funding goals, final expenses (funeral costs, medical bills), and any other financial commitments. You then subtract existing assets (savings, existing insurance, spouse’s income) to arrive at the coverage gap. This method takes more effort but produces a more accurate number.

A financial advisor can help you run both calculations and determine the appropriate amount and type of coverage for your family’s specific needs.

Term Life Insurance Explained

Term life insurance is the simplest and most affordable form of life insurance. You pay a fixed premium for a set period — typically 10, 15, 20, 25, or 30 years — and if you die during that term, the policy pays a death benefit to your beneficiaries. If you outlive the term, the policy expires and no benefit is paid.

Term insurance is pure protection. There is no savings component, no cash value accumulation, and no investment feature. This simplicity is exactly what makes it so cost-effective. A healthy 35-year-old can typically purchase a 20-year, $500,000 term policy for $25 to $35 per month — a fraction of what permanent coverage would cost.

Term policies are ideal for covering temporary financial obligations: the years while your children are growing up, the period during which you are paying down a mortgage, or the working years before your retirement savings can sustain your spouse independently.

Permanent Life Insurance Types

Permanent life insurance provides coverage for your entire lifetime, as long as premiums are paid. Unlike term insurance, permanent policies include a cash value component that grows over time on a tax-deferred basis. There are three primary types.

Whole Life Insurance offers guaranteed premiums, a guaranteed death benefit, and a guaranteed minimum rate of cash value growth. It is the most predictable form of permanent insurance. Participating whole life policies may also pay dividends, though dividends are not guaranteed. The trade-off is cost: whole life premiums are typically 5 to 10 times higher than term premiums for the same death benefit amount.

Universal Life Insurance provides more flexibility than whole life. You can adjust your premiums and death benefit within certain limits, and the cash value earns interest at a rate tied to current market rates (with a guaranteed minimum). This flexibility is appealing, but it also means the policy’s performance depends on interest rates. If rates remain low for extended periods, you may need to pay higher premiums to keep the policy in force.

Variable Universal Life Insurance allows you to invest the cash value in sub-accounts similar to mutual funds, offering the potential for higher returns — but also the risk of investment losses. If the underlying investments perform poorly, your cash value could decline, and you may need to increase premiums to maintain coverage. This type of policy requires active monitoring and a higher tolerance for risk.

The cost difference between term and permanent life insurance is significant. The chart below compares estimated monthly premiums for a healthy 35-year-old purchasing $500,000 of coverage.

For the price of one whole life policy, you could purchase more than 13 times the death benefit in term coverage. This is why many financial advisors recommend “buying term and investing the difference” — purchasing affordable term insurance for protection and directing the premium savings into tax-advantaged retirement accounts or other investments.

When Term Makes Sense

Term life insurance is the right choice for most families in the following situations:

• Young families with children: You need maximum coverage during the years your children are dependents. A 20- or 30-year term covers this window affordably.
• Mortgage protection: A term policy matched to your mortgage length ensures your family can stay in their home if you pass away.
• Income replacement during working years: Until your retirement savings are sufficient to support your spouse, term insurance bridges the gap.
• Budget constraints: When every dollar counts, term insurance delivers the most coverage per premium dollar.

When Permanent Makes Sense

Permanent life insurance serves specific, often more complex needs:

• Estate planning and wealth transfer: For high-net-worth individuals, permanent insurance held in an irrevocable life insurance trust (ILIT) can provide liquidity to pay estate taxes, ensuring heirs do not need to sell assets.
• Business succession: Permanent insurance can fund buy-sell agreements between business partners, ensuring a smooth ownership transition.
• Lifelong dependents: If you have a child with special needs or another dependent who will require support for their entire life, permanent coverage ensures a guaranteed benefit whenever you pass.
• Supplemental retirement income: The cash value in a well-funded whole life policy can be accessed through loans or withdrawals in retirement, though this should be a secondary strategy rather than a primary retirement plan.

Common Mistakes to Avoid

The most common life insurance mistake is being over-insured with the wrong type. Many people purchase expensive permanent policies when an affordable term policy would more than meet their needs — often because permanent insurance generates higher commissions for the agent selling it. Before purchasing permanent coverage, make sure there is a specific, identifiable need that term insurance cannot satisfy.

The second most common mistake is being under-insured. Some families carry no life insurance at all, or only the modest group coverage provided by an employer (typically one to two times salary). Employer coverage often disappears when you change jobs and may not be sufficient even while you are employed. Owning an individual policy ensures continuous coverage regardless of employment changes.
