If you have life insurance at all, there’s a decent chance you picked the number the way most people do: a round figure based on “industry norms,” or whatever amount a workplace policy happened to offer. Neither one was built to accommodate your actual living situation.
According to the American Council of Life Insurers, roughly 102 million Americans are currently uninsured or underinsured when it comes to their life insurance policy, and nearly half say they’d face financial hardship within six months if their household’s primary earner passed away.
That’s not a case for buying more coverage than you need. It’s a case for understanding where your number actually comes from before you’re sitting across from someone quoting you a policy. Once you know roughly what you’re working with, an independent agent can take the real specifics of your household and tell you exactly what you need.
What Actually Moves the Number
Before any formula, it helps to know what a life insurance formula is reacting to. Coverage needs shift with:
- Who depends on your income. A spouse, kids, an aging parent — the more people counting on what you bring in, the more that income needs to be replaced.
- What you owe. A mortgage, car loans, and credit card balances don’t disappear; they pass to whoever’s left holding the household’s finances.
- How long that support needs to last. A newborn implies 18-plus years of runway. A household with teenagers about to launch needs a much shorter bridge.
- What you’ve already set aside. Savings, investments, and any coverage you already carry all reduce what a new policy needs to cover.
None of that requires a separate spreadsheet; it’s the raw data every method below is trying to turn into a dollar figure.
The Rule of Thumb, and Why It’s Only a Starting Point
Search for an answer and you’ll run into a familiar shortcut fast: carry 10 to 12 times your annual income in coverage.
It’s memorable, and it’s not exactly wrong. It’s just incomplete. A flat income multiple treats a single 28-year-old renter and a 40-year-old with a mortgage and three toddlers the same way, and those two households require very different amounts of protection.
Where the multiplier actually earns its keep is as a sanity check on a number that’s calculated more deliberately (not as the number itself).
A Needs-Based Approach: The DIME Method
A more accurate way to size a policy is often called the DIME method, and it works by adding up what a policy would actually need to cover rather than multiplying a single figure:
- Debt — everything your family would inherit that isn’t the mortgage: car loans, credit cards, student loans
- Income replacement — your annual income multiplied by the number of years your household would need it replaced. A young family with kids at home typically needs more years than a household closer to retirement
- Mortgage — what’s left on the home loan, so your family isn’t forced to sell to cover it
- Education — future costs for any kids who’d still be headed to college
DIME doesn’t automatically include final expenses, so it’s worth adding those in separately. Nationally, the median cost of a funeral with burial runs around $8,300, but in Washington a traditional burial can average well above $7,800 and run past $16,000 depending on the arrangements. Cremation tends to land well below either figure.
Add all of these figures together, then subtract what you already have — existing coverage, savings set aside for this purpose — and what’s left is your coverage target.
Here’s what that looks like for a hypothetical household:
CATEGORY |
AMOUNT |
|---|---|
| Non-mortgage debt | $20,000 |
| Income replacement (10 years at $75,000) | $750,000 |
| Remaining mortgage | $250,000 |
| Education (2 kids) | $60,000 |
| Final expenses | $10,000 |
DIME TOTAL: |
$1,090,000 |
| Existing group life policy through work | –$100,000 |
COVERAGE TO SHOP FOR: |
$990,000 |
That’s a very different number than a generic “10x your salary” estimate would have landed on — and it’s the kind of gap that’s easy to miss without actually running the math.
A Few Things That Change What It Costs to Get What You Need
Everything above answers one question: what dollar figure should be on the policy. A separate set of factors doesn’t touch that number at all, but shapes what you’ll actually pay for it and how easily you’ll qualify:
- Age. The earlier you lock in a policy, the lower the premium tends to be for the same coverage amount — age is one of the biggest single drivers of cost, which is part of why “I’ll deal with it later” is rarely the cheaper route.
- Health status. Smoking status, chronic conditions, and general health history all factor into underwriting, and can move a quote significantly in either direction. This is also exactly the kind of detail worth discussing directly with an agent rather than guessing at from an online tool.
- Gender. Because of differences in average life expectancy, pricing can differ between men and women carrying identical coverage amounts and terms.
- Relationship status and household setup. Whether you’re single, married, or supporting a blended household doesn’t change the math behind your DIME number directly, but it does shape who the beneficiary should be and whether more than one policy in the household makes sense.
None of these change the coverage amount you calculated above. They change what that coverage amount will cost you.
Matching the Policy to the Timeframe
Once you have a number, the next question is what kind of policy actually fits it — and that comes down to how long you need the coverage to last, not just how much of it you need.
Term life covers a fixed window, usually 10 to 30 years, and it’s built for needs with a natural end date: the years until a mortgage is paid off, the years until the kids are through college, the years until retirement changes what your family would need to replace. It’s also the more affordable route for the same amount of coverage, which is part of why it’s the default recommendation for most of the DIME number above.
Permanent coverage (whole or universal life) doesn’t expire as long as premiums are paid, and it builds cash value along the way. It fits differently shaped needs: a policy meant to fund a business succession plan, support a dependent who’ll need care indefinitely, or leave a deliberate legacy rather than replace income for a set number of years.
Most households end up leaning term for the bulk of their DIME number, sometimes with a smaller permanent policy layered in for a need that doesn’t have an expiration date. Which mix makes sense depends on what that money actually needs to do.
What the Math Alone Won’t Tell You
A few things don’t show up in any formula, and they’re exactly where a conversation with an agent earns its place over a calculator:
- Workplace coverage rarely travels with you. Group life through an employer is valuable, but it typically ends the day you leave the job — which matters if you’re counting it as part of your long-term number. It also tends to be modest on its own: a common structure is one to two times salary, well short of most DIME totals.
- Survivor benefits from Social Security can offset part of the income-replacement figure, but only for households that qualify, and only by a specific amount worth calculating rather than assuming.
Those two points work well together, not against each other. If your DIME number comes out to $1,000,000 and you already have $100,000 in group coverage through work, the move isn’t necessarily to replace that policy — it’s to layer an individual policy underneath it that covers the remaining $900,000, then adjust as your workplace coverage or your needs shift.
This highlights the importance of running the actual numbers with someone who can walk through your specific household, rather than relying on a generic policy calculator.
When It’s Worth Recalculating
A coverage number isn’t something you set once. It’s worth revisiting after:
- A new baby, marriage, or divorce
- Buying a home or paying off a mortgage
- A significant raise or new job
- Kids finishing school or moving out
- Getting closer to retirement, when income-replacement needs typically shrink
From Estimate to Actual Coverage
Although the 10-12x rule feels safe, and a workplace policy feels like it’s already handled, neither tells you what your household would actually need if it had to run on savings, survivor benefits, and what’s left on the mortgage.
That’s the gap an independent agent closes. We’re not selling one company’s version of the right number — we sit down with your actual debts, your actual income, your actual mortgage balance, and build the figure from there, specific to your household instead of a hypothetical standard. Then we tell you plainly where your current coverage lands against it, and what closing that gap would actually cost.
A single earner with a mortgage and young kids needs a very different policy than a couple where both incomes matter, or a household where one spouse’s coverage is doing all the work for the entire family’s future. At Mark Weedin Insurance, we walk through your whole household — not just whoever asked the question — because the number that protects your family only works if every part of it was actually accounted for, not assumed.
Don’t rely on an estimate — let’s find your actual number.
