Life Insurance: The Math Behind Coverage

Basic rule: 10-12x annual income. Earning $75K? Need $750K-900K coverage. Why? Replace your income for 10+ years, cover mortgage, pay debts, fund kids' college. A 30-year-old, healthy male pays ~$35/month for $500K 20-year term policy. That's $8,400 total for half a million in protection.

Two types matter: Term (rent coverage for 10-30 years, cheap) and Whole Life (permanent coverage with cash value, 10x more expensive). 98% of people should buy term and invest the difference. Whole life makes sense for estate planning with $2M+ estates, not average families.

Quick Coverage Formulas

Income Replacement Method

Annual Income × 10-12

Quick estimate for working adults

Example: $80K salary = $800K-960K coverage

DIME Method (Detailed)

  • Debt (mortgage, loans)
  • Income (years to replace × annual)
  • Mortgage (remaining balance)
  • Education (college costs)

Coverage Needs by Life Stage

Life Stage Typical Need Key Factors
Single, No Kids $0-100K Only if you have debt or want to cover funeral ($10-15K)
Married, No Kids $250K-500K Cover mortgage, replace income for spouse
Young Family (Kids 0-10) $750K-1.5M Peak need: mortgage + 15-20 years income + college
Older Family (Kids 10-18) $500K-1M Less years to replace, but college approaching
Empty Nesters $100K-250K Cover remaining mortgage, final expenses
Retired $0-50K Final expenses only if no savings

Term vs Whole Life Insurance

Term Life (Recommended)

Coverage: 10, 20, or 30 years

Cost: $20-50/month for $500K

Pros: Cheap, simple, high coverage

Cons: Expires, no cash value

Best for: 98% of people

Whole Life (Rarely Needed)

Coverage: Lifetime

Cost: $400-600/month for $500K

Pros: Permanent, builds cash value

Cons: 10x more expensive, complex

Best for: Estate planning ($2M+ net worth)

Sample Cost Breakdown

Age/Health $500K 20-Year Term $1M 20-Year Term
30, Healthy Male $25-35/month $40-55/month
30, Healthy Female $20-30/month $35-45/month
40, Healthy Male $40-55/month $70-95/month
40, Healthy Female $35-45/month $60-80/month
50, Healthy Male $110-140/month $200-260/month
Note: Rates increase significantly with age. Smokers pay 2-3x more. Medical conditions (diabetes, heart disease) increase rates 50-200%.

Common Mistakes to Avoid

Don't Do This

  • Relying only on employer life insurance (1-2x salary, not enough)
  • Buying whole life when term is better
  • Waiting until you're older (costs double every decade)
  • Getting too little coverage to save money
  • Forgetting to cover stay-at-home spouse

Do This Instead

  • Buy 10-12x income in term coverage
  • Get quotes from 3-5 companies
  • Buy while young and healthy (lock in low rates)
  • Cover both spouses adequately
  • Review coverage every 5 years

Do You Need Life Insurance?

You NEED It If:

  • Anyone depends on your income (spouse, kids)
  • You have debt others would inherit (co-signed loans)
  • Funeral costs would burden family ($10-15K)
  • You're the breadwinner or sole earner

You DON'T Need It If:

  • Single with no dependents or debt
  • Financially independent (enough assets to self-insure)
  • Retired with sufficient savings/pension
  • Kids grown and financially independent

Frequently Asked Questions
