How Much Life Insurance Do You Actually Need? A Worksheet-Style Guide

Start With the Quick Rule: 10–15x Your Income

The fastest way to get in the right neighborhood is to multiply your gross annual income by 10 to 15. Someone earning $60,000 a year would look at roughly $600,000 to $900,000 of coverage under this rule.

Why that range? The goal of life insurance is income replacement: giving your family enough capital that, invested prudently and drawn down over time, it can replace your paycheck for a decade or more while they adjust, pay off major obligations, and fund future goals.

Use the higher end of the range if you have young children, a single-income household, significant debt, or college costs ahead. The lower end may fit if your kids are nearly independent, your mortgage is small, or your spouse earns a strong income of their own. The income multiple is a starting point — the DIME method below turns it into a number tailored to you.

The DIME Method: A Four-Line Worksheet

DIME stands for Debt, Income, Mortgage, Education. Add up the four lines and you have your coverage target:

• D — Debt and final expenses: All non-mortgage debt (car loans, credit cards, personal loans, private student loans that would not be discharged at death) plus an allowance for funeral and final expenses.
• I — Income replacement: Your annual income multiplied by the number of years your family would need support. A common choice is the number of years until your youngest child is independent, or until your spouse reaches retirement eligibility.
• M — Mortgage: The remaining balance on your mortgage, so your family could pay off the house outright and remove the biggest monthly bill.
• E — Education: Estimated future education costs per child — whatever you would realistically want to fund, whether that is in-state tuition, private college, or trade school.

Then subtract what you already have: existing life insurance (including employer group coverage you would keep), savings and investments your family could draw on, and any survivor benefits. What remains is the gap to insure.

A Worked Example (Illustration Only)

Here is a hypothetical family — the numbers are an illustration, not a quote or a recommendation for any specific person. Maria is 35, earns $75,000 a year, is married with two kids ages 3 and 6, and is the primary earner.

Notice the result — $1.4 million — lands well above the simple 10x-income figure of $750,000. That is common for young families with long income-replacement horizons and a full mortgage. It is also why guessing tends to leave families short. And because term insurance for a healthy 35-year-old is generally inexpensive relative to the coverage amount, closing a large gap is usually more affordable than people expect — get a real quote rather than assuming.

Term vs. Whole Life: Match the Product to the Need

Once you know how much, the next question is what kind. For the need we just calculated — replacing income and covering a mortgage and education during your working years — term life insurance is usually the right tool. It covers a fixed period (commonly 10, 20, or 30 years) at a level premium, and because it has no cash value component, you get the most coverage per premium dollar. Match the term to the need: a 20- or 30-year term for a young family typically carries you until the mortgage is paid and the kids are independent.

Whole life insurance lasts your entire life and builds cash value, but the same death benefit costs substantially more. It makes sense for genuinely permanent needs: final expenses, estate planning and liquidity, funding a special-needs trust, or business succession. Many families use a layered approach — a large term policy for the working-years gap, plus a smaller permanent policy for lifelong needs. What rarely makes sense is buying a small whole life policy instead of adequate term coverage because the premium looked comparable; that trades away the protection your family actually needs.

Should Both Spouses Be Insured? (Usually Yes)

A common mistake is insuring only the higher earner. Run the DIME math for each spouse separately, because:

• A stay-at-home parent has real economic value. If they died, the surviving earner would face childcare, household management, and transportation costs that can easily run tens of thousands of dollars a year — and might need to reduce work hours on top of that. A meaningful policy on a non-earning spouse is not a luxury.
• Dual-income households usually depend on both incomes. If your mortgage, savings rate, or lifestyle assumes two paychecks, each spouse needs coverage sized to their own income and obligations.
• Insurability is easiest now. Health changes can make coverage expensive or unavailable later, so it is generally wise to insure both spouses while both are healthy.

Each spouse should own an individual policy sized to their own numbers rather than relying on a small spousal rider on one policy.

Common Mistakes That Leave Families Underinsured

Even people who run the math often stumble on a few predictable traps:

• Relying on employer coverage alone. Group life is typically one to two times salary — a fraction of the 10-15x guideline — and it usually disappears when you change jobs, exactly when replacing it may cost more because you are older. Treat it as a bonus, not a plan.
• Buying a round number instead of a calculated one. $250,000 or $500,000 sound substantial, but as the worked example shows, a family's real need can be two or three times that. Run the DIME lines before anchoring on a figure.
• Choosing a term that is too short. A 10-year term is cheaper, but if your youngest is 3, you will need coverage far longer — and renewing at 45 or 55 costs much more than locking in a 20- or 30-year term today.
• Forgetting inflation. A death benefit sized to today's grocery bills and tuition will buy less in 15 years. Rounding your target up, or revisiting coverage every few years, keeps the number honest.
• Ignoring debts with cosigners. Federal student loans are generally discharged at death, but private loans with a cosigner and jointly held debt can survive you. Make sure the D in DIME captures them.
• Waiting for a perfect moment. Premiums are based largely on age and health at purchase. Every birthday — and every new health condition — makes the same coverage more expensive.

How Your Number Changes by Life Stage

Your life insurance need is not a fixed number — it typically peaks in your 30s and 40s and declines as obligations fall away:

• Single, no dependents: Need is often modest — enough for debts that would fall to a cosigner and final expenses. Locking in a policy while young and healthy can still be smart because premiums are based partly on age and health at purchase.
• Newly married: Cover shared debts and enough income replacement for your spouse to maintain the household.
• Young kids and a new mortgage: Peak need. Long income horizon, full mortgage balance, all education costs still ahead. This is where the DIME total is largest.
• Teens and a half-paid mortgage: Need is falling. Fewer income-replacement years remain and education is partially funded. A laddering strategy — stacking a 30-year and a shorter term policy — can mirror this decline instead of paying for peak coverage the whole time.
• Empty nest and near retirement: If savings are strong and the mortgage is gone, you may need little or no term coverage. Remaining needs are often final expenses, a survivor's income gap, or estate goals — which is where permanent coverage can fit.

Revisit the worksheet after every major life event: marriage, each child, a home purchase, a big raise, or a divorce. Ten minutes of math beats years of being underinsured — and a licensed agent can run these numbers with you and quote multiple carriers at no cost.
