Insurance Need Methods Compared

DIME Method
—
Debt + Income + Mortgage + Education. Most comprehensive approach recommended by financial planners.
10× Income Rule
—
Annual income × 10. Quick rule of thumb — easy to calculate but may undercount debt and education costs.
12× Income Rule
—
Annual income × 12. Conservative multiplier favored for families with young children or significant debts.
Human Life Value
—
Present value of future earnings at 5% discount. Best for wage earners with long careers remaining.
Needs Analysis
—
Living expenses × replacement years. Focuses on maintaining family lifestyle without income.
Recommended Gap
—
DIME Need minus your existing coverage and savings — the additional policy you should buy today.

Policy Laddering Strategy

Instead of one expensive long-term policy, a ladder of 3 shorter-term policies covers the same total need at a significantly lower cost — as each policy expires, so does the need it was covering.

Frequently Asked Questions

Basics How much life insurance do I actually need?
Most financial planners recommend using the DIME method: sum your Debts (non-mortgage), Income replacement need, Mortgage balance, and Education costs for children. Subtract existing coverage and savings. The result is your coverage gap. As a quick rule of thumb, 10-12x your annual income is a reasonable starting point.
Basics Term vs whole life insurance — which should I choose?
Term life insurance is pure protection for a defined period (10, 20, or 30 years) and is far more affordable. Whole life combines insurance with a savings component and costs 5-15x more. Most financial experts recommend term for the majority of people, investing the premium difference in low-cost index funds.
Basics What is the DIME method?
DIME stands for Debt (excluding mortgage), Income replacement, Mortgage, and Education. Sum all non-mortgage debts, multiply your income by the years you want to replace it, add the remaining mortgage balance, and add expected college costs per child.
Basics Who should I name as beneficiary?
Typically your spouse or domestic partner, followed by children as contingent beneficiaries. Keep beneficiary designations updated after major life events (marriage, divorce, birth of a child). Note that beneficiary designations override your will.
Basics What factors affect my life insurance premium?
Age, health class, tobacco use, gender, coverage amount, policy term, occupation, and driving history all affect premiums. Younger and healthier applicants pay significantly less. Preferred Plus rates are roughly 30% lower than Standard rates.
Basics When should I review my life insurance coverage?
Review coverage after major life events: marriage, divorce, having children, buying a home, significant income changes, or retirement. Your need typically decreases as you pay down debts and build savings over time.
Basics What is policy laddering?
Policy laddering means purchasing 2-3 smaller policies with different term lengths rather than one large long-term policy. Because shorter-term coverage is cheaper per dollar, you pay lower total premiums while maintaining adequate coverage throughout your life.
Basics What is key person insurance for a business?
Key person insurance protects a business against the financial loss caused by the death of a critical employee or owner. The business owns the policy and receives the benefit, which can cover recruitment costs, lost revenue, and loan repayment.
Basics How much does term life insurance cost?
A healthy non-smoking 35-year-old can get $500K in 20-year term coverage for ~$25-$40/mo at Preferred rates. $1M coverage runs ~$35-$65/mo. Rates double approximately every 10 years of age, and smokers pay 2-3x more.
Basics Do I need life insurance if I'm single with no dependents?
Generally no, unless you have significant debts with cosigners, plan to have dependents soon, or want to lock in low rates while young and healthy.
Basics Is employer-provided life insurance enough?
Usually no. Employer policies typically provide 1-2x salary, which is insufficient for most families. They are also not portable — if you leave the job, you lose the coverage. Always supplement with a personal policy.
Basics What is the Coverage Score?
The Coverage Score (0-100) is our composite metric that measures how well-covered you are. It considers how much of your DIME need is already funded, your income replacement duration, and your savings buffer. 70+ is well-covered; below 40 is critically undercovered.
Basics Should I inflation-adjust my income replacement?
Yes, for longer replacement periods. Inflation-adjusting at 3% p.a. using a PV annuity formula gives a more accurate coverage target. For 10-year windows the difference is modest; for 20-30 year windows it can add 15-30% to the coverage need.
Basics What is the difference between beneficiary and insured?
The insured is the person whose life is covered. The beneficiary receives the death benefit if the insured dies. These are typically different people — for example, you are the insured and your spouse is the beneficiary.
Basics Does life insurance cover suicide?
Most policies have a 2-year suicide exclusion — meaning claims for suicide within 2 years of policy issue may be denied. After the exclusion period, most policies do cover suicide.

Key Terms Explained

Term Life Insurance
Coverage for a fixed period (10, 20, 30 years). Cheapest per dollar of coverage. Pure death benefit, no cash value.
Whole Life Insurance
Permanent coverage with a cash value component. Much more expensive; builds equity over time.
DIME Method
Life insurance needs formula: Debt (non-mortgage) + Income × years + Mortgage + Education costs.
Human Life Value (HLV)
Present value of all future earnings, discounted at ~5%. Represents the total economic value of the insured.
Health Class
Insurer risk category (Preferred Plus, Preferred, Standard, Substandard). Preferred Plus can be 30-40% cheaper than Standard.
Policy Ladder
Strategy of buying 2-3 policies with staggered terms to match declining coverage needs at lower total cost.
Rider
Optional add-on to a policy (e.g., accidental death, disability waiver of premium, children's term rider).
Underwriting
Insurer's process of evaluating risk to determine premium — considers age, health, lifestyle, occupation.

Life Insurance: How Much Coverage Do You Need?

Life insurance is the financial safety net that protects your dependents if you die prematurely. Determining how much coverage you need requires analyzing what your income and financial resources currently provide, and estimating what would be needed to maintain your family's standard of living and financial goals without you.

The most widely used framework is the DIME method: Debt (excluding mortgage) + Income replacement + Mortgage + Education. Add up all outstanding non-mortgage debts, calculate income replacement (your annual income x years to replace, optionally inflation-adjusted), add the remaining mortgage balance, and estimate future education costs for children. This sum gives you a solid coverage target. Subtract existing coverage and liquid assets to find the true gap.

Term life insurance is almost always the right product for income replacement purposes. A 20-year term policy for $1 million typically costs $30-$60 per month for a healthy, non-smoking 35-year-old. Whole life and universal life are much more expensive and typically appropriate only for specific estate planning, business succession, or lifelong dependent situations.

Several factors affect your premium beyond coverage amount. Age is the biggest driver. Health class matters significantly: Preferred Plus rates can be 30-40% lower than Standard. Smokers pay 2-3x more. Gender affects rates by ~15-20%. Applying when young and healthy locks in low rates for the entire policy term.

Your life insurance needs are not static. They typically decline over time as your mortgage amortizes, children become financially independent, and you accumulate assets. The coverage decline timeline in the Scenario Analysis tab shows this visually. Review coverage every 5 years or after major life events.
