Types of Insurance Products and Their Applications: How to Choose the Right Coverage for Your Needs?

The core function of insurance is risk transfer, but different types of insurance address distinct needs. With numerous insurance products available, many people get confused or make wrong choices, resulting in either inadequate coverage or wasted premiums. This guide systematically explains the purposes and applications of five major insurance types, and provides guidance on how to properly allocate coverage based on family responsibilities, health risks, financial goals, and other factors.

1. The Roles and Applications of Five Core Insurance Types

1.1 Critical Illness Insurance: Protecting Against Income Loss from Major Illnesses

Purpose:

  • Pays a lump sum upon diagnosis of specified critical illnesses (e.g., cancer, heart attack).

  • Covers treatment costs, rehabilitation expenses, and income loss due to illness.

Ideal For:

  • Primary breadwinners (whose illness could drastically reduce household income).

  • Individuals with family medical history or higher health risks.

Key Considerations:

  • Check disease definitions (ensure coverage for common mild/moderate conditions).

  • Recommended coverage: 3-5 times annual income (e.g., ¥600K–1M for ¥200K/year income).

1.2 Medical Insurance: Reimbursing Hospital/Outpatient Expenses

Purpose:

  • Supplements social insurance by covering non-reimbursable costs (e.g., imported drugs, VIP wards).

  • Common types:

    • High-deductible (millions coverage, low premium).

    • Mid-to-high-end (includes private hospitals).

Ideal For:

  • Everyone (especially those without social insurance or seeking better healthcare).

  • Best paired with critical illness insurance for full financial protection.

Key Considerations:

  • Note deductibles (e.g., ¥10K out-of-pocket before coverage starts).

  • Prioritize policies with 20-year guaranteed renewal.

1.3 Life Insurance: Safeguarding Family Financial Obligations

Purpose:

  • Pays beneficiaries upon the insured’s death/total disability.

  • Types:

    • Term life (e.g., 20/30 years, affordable).

    • Whole life (permanent, costlier).

Ideal For:

  • Primary earners (especially with mortgages/children’s education expenses).

  • Business owners (for estate planning).

Key Considerations:

  • Coverage should cover debts + 10 years of living expenses (e.g., ¥1M mortgage + ¥500K education = ¥1.5M minimum).

  • Term life is cost-effective for most families.

1.4 Accident Insurance: Covering Disability/Death from Injuries

Purpose:

  • Pays lump sums for accidental death/disability.

  • Often includes outpatient reimbursement (e.g., fractures, car accidents).

Ideal For:

  • Everyone (especially high-risk occupations like construction workers/drivers).

  • Frequent travelers (add-on aviation coverage recommended).

Key Considerations:

  • Verify if "sudden death" is covered (often excluded).

  • Avoid long-term accident plans (annual policies offer better value).

1.5 Annuity/Whole Life (Cash Value): Long-Term Savings & Retirement

Purpose:

  • Annuities: Provide regular payouts (e.g., from age 60) for retirement.

  • Cash-value life insurance: Grows tax-deferred funds for withdrawals/legacy.

Ideal For:

  • Steady earners seeking forced savings.

  • Retirement planning (to supplement pensions).

  • Estate isolation/transfer (avoiding inheritance disputes).

Key Considerations:

  • Hold long-term (early surrender may incur losses).

  • Compare IRR (internal rate of return); aim for ≥3%.


2. How to Match Insurance to Your Needs?

2.1 By Family Role

  • Single young adults: Prioritize medical + accident insurance; add critical illness if budget allows.

  • Families with children: Both parents need critical illness + medical + term life; children focus on medical + critical illness + education annuities.

  • Retirees: Supplement with cancer medical + retirement annuities to avoid burdening children.

2.2 By Health Status

  • Healthy individuals: Standard underwriting with broad options.

  • Pre-existing conditions (e.g., hypertension, nodules):

    • Try automated underwriting/multiple applications for lenient policies (e.g., cancer-only plans).

    • Assess if "exclusions" are acceptable (e.g., thyroid nodules not covered).

2.3 By Financial Goals

  • Conservative: Cash-value life/annuities for stable growth.

  • Aggressive: Use insurance only for protection; invest separately (e.g., stocks/funds).


3. Golden Rules for Insurance Planning

  1. Protection before savings: Secure health/life coverage first, then consider annuities.

  2. Parents before children: Adults are kids’ ultimate safety net.

  3. Adequate coverage matters: Avoid "underinsurance."

  4. Review periodically: Adjust every 3–5 years for life changes.

There’s no "best" policy—only the "right fit" for your situation. By clarifying needs and strategically combining coverage, insurance becomes a true safety net for your family.
