How Much Term Life Do I Need? The DIME Method, With a Worked Example

“How much life insurance do I need?” is one of the first questions families ask, and one of the hardest to answer on the spot. Rules of thumb like “10 times your income” are easy to remember, but they don’t know anything about your mortgage, your kids, or your savings. The DIME method is a simple, structured way to build a number from your own life. Here’s how it works, with a worked hypothetical you can follow at the kitchen table.

Quick takeaway

• DIME stands for Debt, Income, Mortgage, and Education. Add those four, then subtract savings and coverage you already have.
• The income piece is usually the biggest number, so think carefully about how many years your family would need it.
• The result is a starting point for a conversation, not a final answer. Your budget and underwriting also shape what you buy.
• The longest need you list, like the years until your youngest is grown, is a good guide to term length.

What DIME stands for

DIME is an acronym for the four big needs life insurance is often used to cover:

• D — Debt: credit cards, car loans, student loans, medical bills, and other debts besides your mortgage. Many people add final expenses here too.
• I — Income: the paychecks your family would lose, multiplied by the number of years they’d need them.
• M — Mortgage: the payoff balance on your home loan, or several years of rent if you rent.
• E — Education: what you’d like to set aside for your children’s college or training.

Add the four together, then subtract what your family could already use: savings, investments meant for this purpose, and existing life insurance. What’s left is an estimate of the coverage gap.

A worked example (hypothetical)

Let’s walk through a made-up Middle Tennessee family. These numbers are for illustration only and aren’t based on any real household or typical costs.

Jordan, 35, lives in Murfreesboro with a spouse and two kids, ages 3 and 6. Jordan earns $70,000 a year.

1. Debt: a $15,000 car loan and $5,000 on credit cards, plus $10,000 Jordan would like set aside for final expenses. Total: $30,000.
2. Income: Jordan’s family would like to replace Jordan’s income until the youngest is 18, which is 15 years. $70,000 × 15 = $1,050,000.
3. Mortgage: the payoff balance is $280,000.
4. Education: Jordan would like to set aside $40,000 per child. Total: $80,000.

DIME total: $30,000 + $1,050,000 + $280,000 + $80,000 = $1,440,000.

Now subtract what’s already in place:

• Group life insurance through work: $140,000 (twice salary). Remember that it usually ends if Jordan leaves the job.
• Savings the family could use: $35,000.

$1,440,000 − $175,000 = about $1,265,000 in estimated need.

That’s a big number, and it’s meant to be. It’s the full picture if Jordan wanted to replace everything. From there, the family can make choices.

Adjusting the number to fit real life

DIME gives you a ceiling to think about, not a requirement. Common adjustments include:

• Fewer years of income. Some families replace income only until the surviving spouse could reasonably adjust, not until the kids are grown.
• A partial income. If the surviving spouse works, you may decide to replace a portion of the lost income rather than all of it.
• Excluding group coverage. If you might change jobs, some people don’t count work coverage at all, since it may not follow them.
• Budget. The right policy is one you can keep paying. If the full amount doesn’t fit, a smaller policy now is often better than none.

Because income replacement is usually the largest piece, small changes to the number of years make a big difference. In the example, replacing 10 years of income instead of 15 lowers the estimate by $350,000.

Using DIME to pick a term length

DIME also helps with the second big question: how long coverage should last. Look at your longest need:

• The years until your youngest child is independent
• The years left on your mortgage
• The years of income you decided to replace

In Jordan’s case, the youngest is 3 and the mortgage has 27 years left, so the longest need is 27 years. A 30-year term would cover it. If the family wanted less coverage later, they might combine a 30-year policy with a 20-year policy, sometimes called laddering. Our guide to 10 vs. 20 vs. 30-year term life walks through those choices.

Don’t forget the stay-at-home parent

DIME’s income piece can make it look like a parent without a paycheck doesn’t need coverage. That’s rarely true. If a stay-at-home parent died, the family might need to pay for childcare, transportation, and household help for years. Many families estimate that cost and use it in place of “income.” Our article on life insurance for new parents covers this in more detail.

DIME vs. “10 times your income”

A multiple of income is quick, but it can miss a lot. A family with a large mortgage and young kids may need more than 10 times income, while an older couple with a paid-off house and grown kids may need much less. DIME takes a few more minutes but reflects your real situation. Many people run both and talk through the difference.

What DIME doesn’t cover

DIME is simple on purpose. It doesn’t account for inflation, investment returns, taxes, Social Security survivor benefits, or a spouse’s future earnings. It also doesn’t address estate planning or business needs. For those, a deeper review with your agent, and sometimes a financial planner or attorney, helps.

Frequently asked questions

What is the DIME method for life insurance?

It’s a way to estimate coverage by adding Debt, Income replacement, Mortgage, and Education costs, then subtracting savings and existing coverage.

Is DIME better than buying 10 times my salary?

It’s more personal. A salary multiple ignores your mortgage, kids, and savings, while DIME is built from them. Many people use both as a check.

Should I count life insurance from work?

You can, but group coverage often ends when you leave the job. Some people count only coverage they own personally.

How do I choose a term length with DIME?

Look at your longest need, such as the years until your youngest is grown or your mortgage is paid, and choose a term that covers it.
