How Much Life Insurance Do I Need?

It's the question I get asked more than any other: "How much life insurance do I actually need?" The honest answer is that it depends on your specific situation — but it's not as complicated as the industry sometimes makes it sound. In about ten minutes, you can land on a number that's right for your family.

This guide walks through two methods financial professionals actually use, plus a few real-world examples from clients here in the Five Towns and Nassau County. By the end, you'll have a defensible coverage number you can take to a quote calculator with confidence.

The Quick Answer (For People in a Hurry)

Most working adults with a family need somewhere between 10 and 15 times their annual income in term life coverage. So if you earn $150,000 a year, you're looking at $1.5M to $2.25M of coverage. For a 35-year-old in good health, that level of protection often costs less than a streaming subscription.

That's the napkin-math version. For most people, it's accurate enough. But if you want to be more precise — or if your situation has wrinkles like a non-working spouse, special-needs child, or a closely-held business — keep reading.

Method 1: The Income Multiplier

This is the rule of thumb most planners default to because it works well for most working households. The logic is simple: your family loses your income when you die, so the death benefit needs to replace enough of it to cover the years they still need it.

Here's the breakdown by life stage:

• Young, no kids, modest debt: 5–7× annual income
• Married, young kids, mortgage: 10–12× annual income
• Peak earning years, multiple dependents, college on the horizon: 12–15× annual income
• Late-career, kids grown, mortgage paid: 5–8× annual income (often less, depending on assets)

The reason the multiplier moves up in the middle of life is that you have the most years of obligations stacked ahead of you — twenty more years of school, eighteen years of childcare and summer camp, a mortgage that won't be paid for another fifteen years. As those obligations roll off, your need for coverage naturally drops.

Method 2: The DIME Formula

If you want a more tailored number, the DIME formula is what I walk most clients through. It stands for Debt, Income, Mortgage, and Education, and it adds up specific dollar amounts your family would actually need to cover.

Letter	What it covers	How to estimate
D — Debt	Credit cards, car loans, student loans, personal loans (everything except your mortgage)	Pull a current balance from each lender; round up to the nearest $5,000
I — Income	Years of replacement income for your family	Multiply your annual gross income by the years until your youngest child finishes college (or however many years your spouse needs)
M — Mortgage	Outstanding mortgage balance	Look at your most recent mortgage statement
E — Education	Future college costs for each child	$120,000–$200,000 per child for in-state public; $300,000+ for private. Adjust for any 529 balance you already have.

Add those four numbers together. Subtract any savings or existing life insurance (workplace coverage counts, but be cautious — it usually disappears when you change jobs). The result is your DIME coverage need.

A Real Example: A Hewlett Family of Four

What If One Spouse Doesn't Work?

This is one of the most important — and most under-insured — situations I see. A stay-at-home parent doesn't earn a paycheck, but they provide enormous economic value: childcare, household management, transportation, sometimes part-time income that gets overlooked. If that parent dies, the surviving spouse either pays for those services in cash or cuts back at work to provide them. Either way, the bills go up.

For a stay-at-home parent, I generally recommend coverage in the $500,000 to $1,000,000 range — enough to fund childcare and household help through the kids' school-age years and to keep the surviving spouse from having to make panicked career decisions in a moment of grief.

The Mistakes I See Most Often

1. Relying entirely on workplace coverage

Most employers offer 1–2× salary in group life. That's not nothing, but it's typically far below what a family with kids actually needs — and it disappears the day you leave that job. By the time you decide you want to convert it to an individual policy, you're older and possibly less healthy, which means much higher premiums. Workplace coverage is a supplement, not a strategy.

2. Buying based on what's "affordable" instead of what's needed

I understand the instinct — people don't want to overspend on a product they hope to never use. But term life insurance is so cheap for healthy people in their 30s and 40s that the difference between "enough" coverage and "not quite enough" coverage is often $20–$40 a month. Stretching a little to fully cover the gap is almost always the right call.

3. Forgetting to account for inflation

If you buy a $1M policy today, that million dollars buys less in 20 years than it does now. For longer-term policies, I usually recommend bumping up the coverage by 10–20% to account for the slow erosion of purchasing power.

4. Underinsuring the lower-earning spouse

People often focus all the coverage on the primary earner and skimp on the spouse. But two-income households are usually built around both incomes — the mortgage, the school choices, the lifestyle. Both spouses generally need substantive coverage if they're both contributing economically.

How Long Should the Term Be?

The "term" in term life is just the number of years the policy stays in force. The most common options are 10, 15, 20, and 30 years. The right answer is usually whichever term matches your longest financial obligation.

• If you have a newborn and a 30-year mortgage, a 30-year term covers both kids through college and pays off the house if you die in your 60s.
• If your kids are already in middle school and your mortgage has 18 years left, a 20-year term usually covers everything.
• If you're in your 50s with grown kids, a 10- or 15-year term often makes more sense — you only need to bridge to retirement, when your investments and Social Security take over.

What's Next?

Once you have a coverage number in mind, the next step is just to see what it costs. Quotes are quick, free, and don't require sharing personal medical information. From there, if the numbers make sense, we can talk through which carriers are likely to give you the best rate based on your health profile.
