What Actually Determines Your Coverage Need

The tool uses the DIME method to build a coverage target from the numbers that actually define your household's financial exposure: the income your family depends on, the mortgage they would still owe, other outstanding debts, and future education costs. Subtract what you already have in savings or existing coverage and you get a net figure worth insuring. The Insurance Information Institute recommends this kind of structured approach over a simple income multiple because it accounts for fixed obligations that would not shrink just because your paycheck stopped.

Age is the main driver of the premium side of this calculator. After that, carriers sort applicants into health tiers: preferred plus, preferred, standard, and substandard. Each tier reflects a different mortality risk profile, and the rate spreads between them can be significant. The National Association of Insurance Commissioners publishes consumer guidance on how underwriting works, which is worth reading before you apply.

DIME Coverage Priced By Term

Once the DIME figure sets your coverage target, term length decides how much that coverage costs per month. A 30-year policy costs more per month than a 10-year one because the insurer is guaranteeing that level rate over a longer window. Smoking status adds a separate multiplier on top of term length, often two to three times the nonsmoker rate, because tobacco use raises mortality risk that much.

Things To Know Before You Buy Term Coverage

The 10 to 12 times income rule is fast and widely cited, but the DIME method adds structure by breaking the total into four specific buckets: income replacement, mortgage payoff, education funding, and other debt. For most families with a mortgage and kids, the DIME number lands 20 to 30 percent higher than 10x income alone, because a house payment and college costs do not disappear just because income does. A fee-only financial planner can refine the number around your actual cash flow and any existing group coverage through your employer.

Term Life Reference Data

The DIME formula and the rate table behind it are documented in full, with a worked example, on the 2026 Insurance Needs Formulas Reference.

Default profile: $75,000 income, 20-year payoff horizon, $250,000 mortgage, $25,000 other debts, $50,000 education fund, $50,000 existing savings, age 35, preferred health, nonsmoker. The worked DIME example and the raw CSV both live on that page.
