Term life vs. mortgage protection from your lender
When you get a mortgage, your lender will usually offer "mortgage protection insurance" (sometimes called creditor insurance) to pay it off if you die. It's convenient — often just a checkbox during your mortgage application, with no separate medical underwriting up front — but it's rarely the best value. The payout goes directly to the bank, not your family, and it's specifically sized to your remaining mortgage balance, not your family's actual broader needs. It typically shrinks as your balance goes down over the years while the premium stays flat, meaning you're effectively paying more per dollar of coverage every year that passes. An independent term life policy for the same amount is usually cheaper for a comparable health profile, pays your family directly as a lump sum, and they decide what to do with it — including paying off the mortgage if that's still what makes sense at the time, or covering other needs first if circumstances have changed.
What DIME actually captures that a mortgage-only number misses
The DIME method — Debt, Income, Mortgage, Education — exists because a family's real financial needs after losing a primary earner go well beyond just the mortgage. Other debts (car loans, credit cards, lines of credit) don't disappear along with the person who was helping pay them. Lost income needs to be replaced for some meaningful stretch of time, not just until the mortgage is paid off, since ongoing living expenses continue regardless. And if there are children, education costs are a real, sizeable future expense that a mortgage-only coverage number ignores entirely. Adding all four together gives a far more complete picture of what coverage would actually be needed to keep a family's plans intact.
How much is "enough" — the honest answer
There's no universally correct number, because it depends heavily on personal circumstances: a dual-income household where either partner's income alone covers expenses needs proportionally less coverage than a single-income household supporting several dependents. The "years of income to replace" input on this page is deliberately left for you to set, since reasonable answers range widely — some people plan for coverage until the youngest child finishes school, others prefer a fixed number like 10 years regardless of family structure, and some tie it to years until a specific retirement or mortgage-payoff date.
This calculator estimates the coverage amount only; the actual premium depends on your age, health, smoking status, and the specific insurer — shop that separately once you know your number, ideally comparing a few different insurers rather than accepting the first quote.
