Most people either guess at their life insurance or rely on whatever their employer provides. Both usually leave the family short. The right amount is not a rule of thumb; it is a calculation based on what the people who depend on you would actually need.
Start with income replacement
If your income disappeared, how many years would your family need it replaced, and at what level? Cover the years your dependents rely on you, often until the children are grown or the mortgage is paid. This is usually the largest piece of the number, and it is the one a quick salary multiple tends to understate.
Add the debts
Add the mortgage, which lets your family stay in the home, plus other debts that would otherwise fall to them: car loans, personal loans, and any debt you have personally guaranteed. Clearing these removes a major source of financial pressure at the worst possible time.
Fund the goals
Then add the things you are working toward that would still matter: college for the kids, and any other goal your income was meant to fund. Subtract existing resources, like savings and current coverage, to find the gap.
Do not forget the second parent
A stay-at-home parent has real economic value, childcare, household management, and more, that would be expensive to replace. Both parents should be covered, not just the primary earner.
Why employer coverage is not the plan
Group life insurance through work is a benefit, not a plan. It is typically a small multiple of salary, and it usually disappears when you leave the job. It is a fine supplement and a poor foundation.
The real number is almost always higher than people expect, and for most families, term life covers it affordably. A coverage review calculates your specific need and finds strong coverage at a fair price.
