How Much Life Insurance Do I Need?

How much life insurance you need comes down to the gap between what your family would need if you passed away and what they would already have. Add up income to replace, debts and goals like college, then subtract savings and existing coverage. The result is a reasonable starting point.

"Ten times your salary" is the number most people have already picked up, from a coworker or an online calculator. As a first guess, that shortcut is fine. But two families with the same income can need very different amounts, so I like to walk through the math with real categories instead of one multiplier.

Three ways to estimate how much life insurance you need

There's no single correct formula. Here are three methods families often use, from simplest to most detailed:

I usually start with a needs-based analysis because it reflects what your family actually has and actually owes.

What to add up

Picture your income stopping tomorrow. What would still need paying for?

Income replacement

How many years would your family need support? Many people use the number of years until the youngest child is on their own, or until a spouse reaches retirement. Multiply the yearly amount they would need by that number of years.

The mortgage and other debts

Include the remaining mortgage balance, car loans, student loans and credit cards. Some families want the house paid off completely, while others only want enough to keep making payments.

Education and childcare

If paying for college or trade school is a goal, include an estimate. Young families may also need to budget for childcare that a surviving parent would now have to pay for.

Final expenses

Funeral costs, medical bills and estate settlement costs are common one-time expenses.

What to subtract

Next, take away the resources your family would already have:

• Savings and investments that your family could reasonably use
• Existing life insurance, including coverage through work (keep in mind it is often not portable if you change jobs)
• Retirement accounts, though many families prefer not to count these because of taxes and long-term needs
• Other income a surviving spouse earns

Survivor benefits from Social Security may also apply in some situations. The rules are detailed, so check SSA.gov for your own estimate rather than guessing. And when thinking about how a surviving spouse would create steady income from a lump sum, my post on diversified income streams offers some useful ideas.

Running the numbers for Jordan's family

The people and numbers below are hypothetical and for illustration only, not a quote or projection.

Jordan is 35, earns $90,000 a year and has two children, ages 3 and 6. Jordan's spouse works part time. Here's a simple needs-based estimate:

• Income replacement: $60,000 a year for 15 years = $900,000
• Mortgage balance: $350,000
• Other debts: $25,000
• College goal for two children: $150,000
• Final expenses: $15,000

That totals $1,440,000. Jordan has $60,000 in savings and $180,000 of group life coverage through work. Subtracting $240,000 leaves a gap of about $1,200,000.

Jordan might then look at whether a single policy or two policies with different terms fits that need. The actual amount an insurer will approve depends on underwriting, income and existing coverage.

Why simple rules can miss the mark

A "10 times income" rule would have suggested $900,000 for Jordan. That's a meaningful gap. Then again, a single person with no dependents and no debt might need far less than 10 times income. Rules of thumb don't know your family, so I suggest using them only as a sanity check.

If you're still learning the basics, it may help to read how term life insurance works first, and my overview of what term life insurance is.

What can shift your coverage number

• Inflation can shrink the buying power of a fixed benefit over a long term.
• A stay-at-home parent's work has real value, and replacing childcare, cooking and transportation can be costly.
• Your needs usually shrink over time as the mortgage is paid down and kids grow up.
• Insurers set limits on how much coverage they will offer based on income, age and other factors, and all coverage is subject to underwriting.
• Revisit the number every few years or after big life changes.

Where coverage estimates go wrong

• Relying only on group coverage through work, which is commonly a multiple of salary and may end if you leave the job.
• Leaving out childcare or education goals.
• Counting retirement savings your spouse will need later as money available today.
• Choosing a number based only on what feels affordable without first seeing the full need.
• Letting the estimate sit untouched after a new baby, a new home or a raise.

Your coverage amount questions

Is 10 times my income enough?

It can be a starting point, but it may be too high or too low depending on your debts, savings, number of children and goals. A needs-based estimate is usually more accurate.

Should both spouses have coverage?

Many families find that both do, even if one spouse earns less or stays home. Losing either person costs the family something real.

Can I buy more coverage later?

Often, yes, but a new policy requires new underwriting, and it will be priced at your age and health at that time.

Do I need coverage if I'm single with no kids?

Some single people want enough to cover debts, final expenses or support for a parent. Others may need little or none. It depends on who would be affected financially.

Finding your family's gap

The right amount of life insurance comes from your family's real numbers, not a one-size-fits-all rule. Add up the needs, subtract what's already in place, and the gap gives you a clear place to start.
