What is Term Life Insurance?

Term life insurance provides coverage for a specific period (the "term") - typically 10, 20, or 30 years. If you die during the term, your beneficiaries receive the death benefit. If you outlive the term, the coverage expires and no benefit is paid.

Key Features of Term Life Insurance:

  • Temporary coverage: Protects you for a set period
  • Lower premiums: Much cheaper than whole life insurance
  • Level death benefit: Payout amount stays the same
  • No cash value: Pure insurance with no investment component
  • Renewable options: Many policies can be renewed without medical exams

Types of Term Life Insurance in NZ:

  • Level Term: Premiums and death benefit stay the same throughout the term
  • Decreasing Term: Death benefit decreases over time (often used for mortgage protection)
  • Renewable Term: Can be renewed at the end of the term without health questions
  • Convertible Term: Can be converted to whole life insurance later

What is Whole Life Insurance?

Whole life insurance provides permanent coverage that lasts your entire life, as long as premiums are paid. It combines life insurance with a savings/investment component that builds cash value over time.

Key Features of Whole Life Insurance:

  • Lifetime coverage: Coverage never expires if premiums are paid
  • Cash value: Builds savings that you can borrow against
  • Level premiums: Premiums typically stay the same for life
  • Guaranteed death benefit: Beneficiaries are guaranteed a payout
  • Tax advantages: Cash value grows tax-deferred

Types of Permanent Life Insurance in NZ:

  • Whole Life: Traditional permanent coverage with guaranteed cash value growth
  • Universal Life: Flexible premiums and death benefits with investment options
  • Variable Life: Allows you to direct cash value into investment sub-accounts

Cost Comparison: Term vs Whole Life

The cost difference between term and whole life insurance is dramatic, especially for younger applicants:

Example: 35-year-old healthy non-smoker, $500,000 coverage

20-Year Term Life Insurance

$65-95/month

Total 20-year cost: $15,600-$22,800

Whole Life Insurance

$400-600/month

Total 20-year cost: $96,000-$144,000

When to Choose Term Life Insurance

Term life insurance is the right choice for most New Zealand families. Consider term life if you:

✅ Perfect for Term Life Insurance:

  • Have temporary needs (mortgage, young children)
  • Want maximum coverage for minimum cost
  • Are on a tight budget
  • Prefer to invest the premium difference elsewhere
  • Need coverage for 10-30 years
  • Want simple, straightforward insurance

Common Term Life Scenarios:

  • Young families: High coverage needs, limited budget
  • Mortgage protection: Decreasing term matches mortgage balance
  • Income replacement: Protect family income during working years
  • Business protection: Cover key person or business loans

When to Choose Whole Life Insurance

Whole life insurance makes sense in specific situations, though it's not right for everyone:

✅ Good Candidates for Whole Life:

  • Have maxed out other tax-advantaged savings (KiwiSaver, etc.)
  • Want permanent coverage regardless of health changes
  • Need life insurance for estate planning
  • Have a high net worth and want tax-efficient wealth transfer
  • Prefer guaranteed returns over market investments
  • Want to leave a guaranteed legacy

Common Whole Life Scenarios:

  • Estate planning: Ensure inheritance for children
  • Tax planning: Tax-efficient wealth accumulation
  • Charitable giving: Leave money to charity
  • Special needs planning: Provide for disabled dependents

The "Buy Term and Invest the Difference" Strategy

Many financial experts recommend buying cheaper term life insurance and investing the premium difference in higher-growth investments like index funds or property.

Example Calculation:

Monthly Premium Difference: $450 (whole life) - $80 (term) = $370

Invested Monthly: $370 at 7% annual return

After 20 years: Approximately $182,000

Whole Life Cash Value: Approximately $90,000-120,000

Potential advantage: $60,000+ with the invest-the-difference strategy

Important: This strategy requires discipline to actually invest the difference and assumes consistent market returns.

Making the Decision: Term vs Whole Life

For most New Zealand families, term life insurance is the better choice. Here's a simple decision framework:

Choose Term Life Insurance If:

  • You need life insurance but have a limited budget
  • Your need for life insurance is temporary (will decrease over time)
  • You can consistently invest the premium difference
  • You want maximum death benefit for your premium dollar
  • You prefer simple, transparent products

Choose Whole Life Insurance If:

  • You've maxed out other tax-advantaged savings options
  • You want permanent coverage regardless of future health
  • You need life insurance for estate planning purposes
  • You prefer guaranteed returns over market investments
  • You want to force yourself to save money

What Most Financial Experts Recommend

The vast majority of financial experts recommend term life insurance for most people. The reasoning is simple:

  • Life insurance should provide protection, not investment returns
  • Term life provides more protection for less money
  • The investment component of whole life typically underperforms
  • Most people's life insurance needs are temporary
"For most families, term life insurance combined with separate investments provides better financial outcomes than whole life insurance." - Most fee-only financial advisers

Can You Convert Term to Whole Life Later?

Many term life policies include conversion options that allow you to convert to whole life insurance without a medical exam, typically within the first 10-20 years of the policy.

This provides flexibility if your needs change, though converted policies are typically more expensive than buying whole life initially.

Common Mistakes to Avoid

1. Buying Whole Life Too Young

Young people often don't need permanent life insurance and would benefit more from term coverage plus investing the difference.

2. Focusing Only on Cash Value

Whole life's cash value grows slowly and has restrictions. You can often do better with separate investments.

3. Not Buying Enough Coverage

Whole life's high cost might mean you buy insufficient coverage. It's better to have adequate term coverage than inadequate whole life.

4. Treating Life Insurance as an Investment

Life insurance is primarily for protection. If you need investments, consider dedicated investment products.
