Why "10x Your Salary" Is Too Simple
You'll often hear a flat rule like "buy 10x your annual salary" in life insurance coverage. This can be a reasonable rough starting point, but it ignores your actual debts, dependents, existing assets, and specific family circumstances — two people with identical salaries can have very different real coverage needs.
The DIME Method: A More Complete Framework
DIME adds up four categories of financial obligation your family would need covered if you weren't there to provide income:
- Debt — non-mortgage debts (credit cards, car loans, personal loans)
- Income — your annual income × the number of years your family would need it replaced
- Mortgage — your remaining mortgage balance
- Education — future education costs for your children
Coverage Needed = Debt + (Income × Years) + Mortgage + Education − Existing Savings/Insurance
How Many Years of Income Should You Replace?
This depends on your children's ages, your spouse's own earning capacity, and how long you want to provide a financial cushion. Common choices range from 10 to 20+ years — parents of young children often lean toward the higher end, since the replacement income need extends until children are financially independent.
Factors That Increase Your Coverage Need
- Young children with many years of dependency and education costs ahead
- A stay-at-home spouse who would need to cover childcare costs if you passed away, in addition to lost income
- Significant outstanding debt beyond a mortgage
- A single-income household with no other earner to fall back on
Factors That Decrease Your Coverage Need
- Substantial existing savings and investments
- A working spouse with independent income and earning capacity
- Minimal debt and a paid-off or nearly paid-off mortgage
- No dependents, or adult children who are financially independent
Term vs. Permanent: Which Type for This Coverage Amount?
Term life insurance (coverage for a specific period, like 20 or 30 years) is generally significantly less expensive than permanent life insurance for the same coverage amount, and is the more common choice for pure income-replacement needs during working and child-rearing years, when the need is largest and most temporary. Permanent life insurance serves different purposes (estate planning, lifelong coverage, a cash-value component) that are worth discussing separately with a financial advisor if relevant to your situation.
Reassessing Over Time
Your coverage need typically decreases over time as your mortgage is paid down, children become financially independent, and your savings grow — revisit your coverage amount periodically (after major life events like a new child, a home purchase, or paying off significant debt) rather than setting it once and never revisiting.
