The DIME method, in plain English.
DIME is just four numbers added together. Debts you'd leave behind. Income your family needs to replace. Mortgage balance that still has to get paid. Education for your kids. Sum those four, subtract whatever life insurance you already have, and you have a real coverage target — not a rule of thumb.
The reason it works better than "10x income" is that it forces you to look at your actual financial life. A renter with no kids and a 30-year career ahead has a very different real number than a homeowner with two toddlers, even at the same income.
10x income vs DIME — which should you use?
The 10x rule is a screening tool. It's good for a five-second answer at a dinner party. DIME is a planning tool. It's what you should actually buy from.
In practice, run both. If DIME is materially higher, trust DIME — you have obligations the rule of thumb doesn't see. If 10x is higher, your obligations are lighter than your income implies, and the larger number is still a safe ceiling. Either way, you want to be above the higher of the two, not below the lower.
Term vs whole life — why this calculator assumes term.
A 30-year term policy for a healthy 35-year-old can be cheap — often $30–60/month for $1M of coverage. The same coverage in whole life can run $700–1,200/month, because most of the premium goes to a cash-value account, not the death benefit.
If your problem is "I need to make sure my family is fine if I die," term wins on math, simplicity, and flexibility. Whole life solves different problems — estate planning, lifelong coverage for special-needs dependents, certain business structures — that the DIME calculation doesn't address.
Why employer coverage is rarely enough.
Group life through work is convenient and often free up to 1x salary, but it disappears the day you leave the job. For a parent with a 20-year horizon, that's a thin reed to lean on.
Use employer coverage as a bonus layer. Buy an individual term policy sized to your DIME number, owned by you, portable across jobs, and locked at today's rates and today's health.
When you don't need life insurance.
- You have no dependents and no shared debt.
- Your assets already exceed the DIME number — you're self-insured.
- Your kids are financially independent and your mortgage is paid off.
- You're buying whole life as a "forced savings" mechanism — there are better tools.
- Your only motivation is "in case something happens" — be specific about who, exactly, would suffer financially, and how much.
