Before you buy life insurance, determine if you actually need it, how much coverage is required, and why term life beats whole life for 95% of people. The insurance industry profits from selling complex, expensive policies — but the right coverage is usually simple and cheap.

8 Things to Know Before Buying

# Key Point Why It Matters
1 Life insurance replaces your income for dependents If no one depends on your income, you may not need it
2 Term life is almost always the right choice 5-15x cheaper than whole life for the same coverage
3 Coverage amount = what your family needs without you Not a round number — calculate it specifically
4 Buy when you’re young and healthy Premiums locked in at purchase age/health
5 Shop multiple companies Rates vary 30-50% for the same coverage
6 Don’t buy through your employer only Group coverage usually isn’t portable and may not be enough
7 Be honest on the application Lies can void the policy when your family needs it most
8 Avoid policies sold by insurance agents with quotas They’re incentivized to sell the most expensive products

Do You Need Life Insurance?

Situation Need Life Insurance?
Spouse and kids depend on your income ✅ Yes — priority
Have a mortgage or significant debts ✅ Yes
Stay-at-home parent (childcare replacement) ✅ Yes
Single with no dependents ❌ Probably not
Retired with sufficient savings ❌ Probably not
Children are grown and financially independent ❌ Probably not
Have a business partner (buy-sell agreement) ✅ Yes
High net worth (estate tax planning) ⚠️ Maybe — consult estate attorney

How Much Coverage You Need

Need How to Calculate
Income replacement Annual income × years until kids are independent (or spouse retires)
Mortgage payoff Remaining mortgage balance
Other debts Student loans, car loans, credit card debt
Children’s education $100,000-$250,000 per child (estimated future cost)
Final expenses $10,000-$15,000 for burial/funeral
Minus existing savings/investments Subtract what your family already has
= Total coverage needed

Example:

Item Amount
Income replacement ($80K × 15 years) $1,200,000
Mortgage balance $250,000
Student loans $30,000
2 children’s college $400,000
Final expenses $15,000
Minus savings/investments -$200,000
Total coverage needed $1,695,000

Term Life vs. Whole Life

Factor Term Life Whole Life
Coverage period 10, 20, or 30 years Lifetime
Monthly premium ($500K, age 30, healthy) $20-$35 $250-$500
Cash value None Yes (grows at 2-4%)
Complexity Simple Complex
Returns on investment component N/A 1-3% after fees ⚠️
“Buy term, invest the difference” result $400K-$800K+ invested over 20-30 years $50K-$100K cash value in the policy
Best for 95% of people Very specific estate planning situations

Monthly Premium Estimates (Term Life, $500K)

Age 20-Year Term (Excellent Health) 30-Year Term
25 $18-$22 $25-$30
30 $20-$25 $28-$35
35 $22-$30 $35-$45
40 $30-$45 $55-$75
45 $50-$70 $90-$130
50 $80-$120 $150-$220

Premiums are locked in for the entire term. A healthy 30-year-old pays $25/month for 20 years. Waiting to 40 doubles the cost.

Where to Buy

Source Pros Cons
Online term life companies (Haven, Ladder, Bestow) Quick quotes, often no medical exam, competitive rates Limited to term products
Independent insurance broker Shops multiple carriers for you May push more expensive products
Direct from carrier (State Farm, Northwestern Mutual, etc.) Established companies May steer you toward whole life
Employer group policy Easy, may be free for basic coverage Not portable, often insufficient coverage
Fee-only financial advisor recommendation Unbiased (no commission) Must hire an advisor separately

Common Life Insurance Mistakes

Mistake Cost
Buying whole life when term is enough $200-$400/month in unnecessary premiums
Buying too little coverage Family is underprotected
Only relying on employer coverage Lose it when you leave the job
Not disclosing health conditions Policy may be voided at claim time
Waiting too long to buy Premiums increase with age; health changes are unpredictable
Buying life insurance for children Children don’t need income replacement — invest instead
Letting an agent choose your coverage amount They’re incentivized to oversell

The Bottom Line

For most people, the answer is simple: buy a 20-30 year term life policy that covers 10-12x your income (or calculate your family’s specific needs), get quotes from 3+ companies, and lock in the lowest rate while you’re young and healthy. Skip whole life, variable life, and universal life unless a fee-only financial advisor specifically recommends them for your estate planning situation. Invest the premium savings — it will almost always outperform the cash value of a whole life policy.
