Understand life insurance basics, types of policies (term/whole/ULIP), how much coverage you need, and key mistakes to avoid. Updated for 2025.
Life insurance in one sentence
Life insurance is a financial protection plan that pays a benefit to your nominee if you die during the policy term, helping your family maintain their lifestyle and meet long-term goals.
For most families, life insurance is mainly about income replacement. The right plan depends on your dependents, loans, goals, and budget. This guide explains the core concepts so you can choose confidently.
Why Life Insurance Matters
Protects your dependents
- • Replaces lost income
- • Covers children’s education
- • Supports retirement plan for spouse
Handles liabilities
- • Home loan / personal loan repayment
- • Business liabilities (if applicable)
- • Medical/other large obligations
Quick rule
If someone depends on your income (family/parents/loan co-borrower), life insurance is usually worth considering.
Types of Life Insurance
Term life insurance
Pure protection for a fixed period (e.g., 20–40 years). Typically the most cost-effective way to get high cover.
Term vs Whole Life →Whole life / permanent plans
Coverage for longer duration (often lifetime) and may include cash value features. Usually costlier and requires careful comparison.
Endowment / ULIP (investment-linked)
Combines insurance with savings/investment. Evaluate fees, lock-ins, expected returns, and whether it fits your goals. Many people prefer keeping “insurance” and “investment” separate.
Common mistake
Buying a low cover amount because the premium feels cheaper can leave your family under-protected.
How Much Life Cover Do You Need?
A simple way is to estimate income replacement + liabilities + goals minus existing savings.
- Income replacement: 10–20× annual income (varies by dependents and age)
- Liabilities: home loan, personal loan, other EMIs
- Goals: education fund, spouse retirement, emergency buffer
For a precise plan, consider your family’s monthly expenses, how many years they would need support, and inflation.
Checklist Before Buying
- Declare health history honestly to avoid claim issues later.
- Choose nominees correctly and update after life changes.
- Understand riders (accident/critical illness) before adding them.
