Nobody enjoys sitting down to calculate what their family would need if they weren't around to earn a paycheck. That discomfort is exactly why so many people either skip the exercise entirely or grab a random round number that feels "about right." Neither serves the people you're trying to protect — the actual math takes fifteen minutes and removes the guesswork.

Why Life Insurance Matters

Life insurance replaces your income for dependents when you're no longer there to provide it. Without it, a surviving spouse may face: paying off the mortgage alone, funding children's education independently, maintaining the household on one income, and potentially taking on debt. A proper policy handles all of this — and is often less expensive than people assume.

Four numbers, added together, minus what you've already saved — that's your real coverage target.

How Much Coverage You Actually Need

The simplest rule of thumb: 10-12x your annual income. On a $70,000 income, that's $700,000-$840,000 in coverage. This approximation works for many people but ignores your specific debts, number of dependents, existing assets, and lifestyle. The DIME method produces a more accurate, personalized number.

The DIME Formula

D — Debt: All outstanding debts except the mortgage (car loans, student loans, credit cards, personal loans).
I — Income: Annual income × number of years until youngest dependent is financially independent.
M — Mortgage: Outstanding mortgage balance.
E — Education: Estimated cost of college for each child.

Add D + I + M + E, then subtract existing savings and investments. The result is your coverage need.

💡 Example: $15,000 debt + $1,050,000 income (15yr × $70K) + $280,000 mortgage + $120,000 education - $80,000 savings = $1,385,000 coverage needed.

For the vast majority of families, term life insurance is the right choice — maximum coverage at minimum cost during the years you need it most.

When and How to Buy Life Insurance

Buy as early as possible — premiums increase with age and any health changes. A healthy 30-year-old pays roughly $25-$35/month for $500,000 of 20-year term coverage. The same policy at 40 costs $45-$70/month. At 50, $100-$180/month. Shop multiple insurers through independent brokers — identical coverage can vary by 30-50% between companies based on how they underwrite specific health factors.

💡 Don't stop at your employer's group life policy. Most only provide 1-2x your salary — far short of the DIME number above — and critically, it usually doesn't move with you if you change jobs or get laid off, right when you might be least insurable due to age or a new health issue. Treat it as a supplement to your own term policy, not a replacement for it.
