How Much Life Insurance Do I Need? 3 Methods to Calculate Your Coverage

Choosing the right coverage amount is the most important life insurance decision you'll make. Too little and your family struggles; too much and you overpay on premiums for decades.

Here are the three most reliable methods, ordered from quick-and-easy to comprehensive.

Method 1: Income Replacement (10–12×)

The rule: Buy 10–12 times your annual income.

Example: $80,000 salary → $800,000–$960,000 coverage.

Why it works: A $1,000,000 policy invested at a conservative 5% generates $50,000/year — enough to replace most of the lost income indefinitely.

When to use it: You want a quick ballpark and don't have time for detailed analysis.

Limitation: Doesn't account for specific debts, number of children, or a non-working spouse's contribution.

Method 2: The DIME Formula

DIME stands for Debt, Income, Mortgage, Education. Add up each:

When to use it: You want a structured formula that captures the major financial obligations.

Limitation: Income replacement component can be aggressive — adjust down if your spouse earns well or you have substantial savings.

Method 3: Needs Analysis (Most Accurate)

This is what a financial planner does. You map out every financial obligation your death would create and every asset that would offset it.

Needs (what your family would need)

• Final expenses (funeral, medical bills): ~$15,000–$25,000
• Emergency fund (6 months expenses): $30,000
• Mortgage payoff: $320,000
• Other debts: $25,000
• Childcare / education: $120,000
• Income replacement (net of Social Security survivor benefit): $700,000
• Total needs: $1,210,000

Resources (what you already have)

• Existing life insurance (employer group): $160,000
• Savings / investments: $80,000
• Surviving spouse's income (PV of net earnings): $400,000
• Total resources: $640,000

Coverage Gap

$1,210,000 − $640,000 = $570,000 in additional coverage needed.

Don't Forget the Non-Working Spouse

A stay-at-home parent provides enormous economic value — childcare, cooking, household management — that would need to be replaced. The replacement cost of those services often runs $50,000–$100,000/year.

A non-working spouse typically needs $250,000–$500,000 in coverage.

Choosing a Term Length

Match the term to your longest financial obligation:

• 30-year mortgage? → 30-year term
• Kids are 5 and 8? → 20-year term (they're independent by 25–28)
• 10 years to retirement with good savings? → 10 or 15-year term

Most families with young children and a mortgage are best served by a 20- or 30-year term.
