FAQs

How much term insurance do I need?

A practical approach is to cover family expenses to retirement, repay liabilities, and fund major goals, minus existing assets and life cover.

Should inflation be included in life cover planning?

Yes. Inflation can reduce purchasing power over time, so it should be accounted for while estimating goal and income replacement needs.

Is the premium estimate exact?

No. Premiums vary by insurer, health profile, smoking status, and policy terms. Use this as a planning estimate only.

Use Cases

Plan adequate life coverage for your family

Determine the total life insurance amount needed to cover daily expenses, debts, and future goals, ensuring your family's financial stability.

Example: A 35-year-old with $50k annual expenses and $200k mortgage can estimate required cover.

Assess if your existing cover is sufficient

Compare your current life insurance with the recommended amount to identify any coverage gap and decide if additional term insurance is needed.

Example: If existing cover is $300k but recommended is $500k, you may need more.

Frequently Asked Questions

How does the term insurance calculator estimate my life cover?
The calculator uses your current age, retirement age, annual expenses, liabilities, existing assets, existing cover, and future goals. It factors in inflation and expected return rate to estimate the total life cover needed to maintain your family's lifestyle and meet financial obligations.
What inputs do I need to provide?
You need to enter your current age, retirement age, annual expenses (in US$), liabilities (US$), existing assets (US$), existing cover (US$), goal amount (US$), goal years, inflation rate (%), and expected return rate (%). All fields are required for an accurate estimate.
Why is inflation important in life insurance calculation?
Inflation reduces the purchasing power of money over time. The calculator adjusts your annual expenses and future goals for inflation to ensure the recommended cover accounts for rising costs, so your family's needs are met in the future.

Tips & Common Mistakes

Tips

  • Enter realistic figures for annual expenses and liabilities to get a more accurate estimate.
  • Consider future inflation when setting your goal amount and goal years.
  • Review your life insurance needs periodically, especially after major life events like marriage, children, or buying a home.
  • Use the expected return rate that reflects your investment strategy for the insurance proceeds.

Common Mistakes to Avoid

  • Underestimating annual expenses by not including all regular costs like utilities, insurance, and education.
  • Ignoring existing assets and cover, which can lead to overestimating the required life insurance amount.
