Definition:

Decreasing sum assured in term insurance refers to a policy where the final coverage amount, also known as the sum assured, reduces over time at a fixed rate based on a predefined schedule.

This feature is often found in certain term life insurance plans, especially in decreasing term insurance, where the sum assured reduces at regular intervals throughout the policy term, usually in synchronisation with decreasing financial obligations, like loans or mortgages, etc.

Key Takeaways

  • Suitable for individuals with loan repayments.

  • The reduction schedule can be aligned with the repayment of the loan/debt.

  • Premiums for a term insurance policy with a decreasing sum assured are cheaper than those for level term life or permanent life insurance policies

  • Note that decreasing sum assured is not a standard feature across all term insurance policies available in the market; only some policies offer this benefit to the policyholder.

How Does Decreasing Sum Assured Work in Life Insurance?

There are 3 key essential steps to understanding how decreasing sum assured works in a term life insurance plan.
Here's how it works:

1. Initial Coverage: When the policy starts, the sum assured is at its highest. Let’s say ₹1 crore.

2. Scheduled Reductions: At regular intervals, the sum assured decreases based on a fixed schedule, say, by 5% or 10% per year.

3. End of Term: By the end of the policy term, the sum assured might be minimal or even zero (depending on the plan design), especially if your debts are fully repaid.

Here is an example:

Rahul, aged 35, takes a home loan for 20 years worth ₹50 lakhs. He takes a term life insurance plan and chooses a decreasing sum assured.

Year

Year-End Outstanding Loan 

Year End Sum Assured 

How it Works

1

₹47.5 lakhs

₹47.5 lakhs

After 1 year of EMIs, only a small portion of the principal is paid.

5

₹35 lakhs

₹35 lakhs

By year 5, some more principal is cleared.

10

₹20 lakhs

₹20 lakhs

By year 1, which is midway, usually 60–70% of the loan is repaid.

15

₹8 lakhs

₹8 lakhs

In the last 5 years, EMIs mostly go toward the principal, and the balance reduces quickly.

20

₹0 (loan closed)

₹0 (policy ends)

Loan is fully repaid, so insurance cover is no longer needed.

Note:

  • This is a tentative calculation for your understanding. Actual numbers may vary.

  • If Rahul passes away in year 10, the insurer will pay ₹20 lakhs, which is the policy cover at that time. This payout can help clear the outstanding loan.

Decreasing Sum Assured vs Level Sum Assured

Sum Assured is defined as the amount which the insurer pays out when a claim is made. However, in the case of a decreasing sum assured in term insurance, the amount to be paid out by the insurer reduces over time. 
Remember, all life insurance policies have a sum assured - it's the base concept.

  • Decreasing (reduces over time)

  • Level (remains constant throughout)

Why Decreasing Sum Assured Matters For Policyholders?

Here are a few important factors a policyholder should know before getting a plan with a decreasing Sum Assured:

Benefits of decreasing sum assured:

  • A cost-effective way to manage short-term or reduce financial obligations.

  • The sum assured is aligned with loan repayment timelines and also reduces the risk for the insurer.

Risks of decreasing sum assured:

  • Coverage reduces every year. 

  • Not ideal for family protection or income replacement.

Applicable situations of decreasing sum assured:

  • Loan protection against home, education, business, and personal loans.

  • Mortgage-linked term plans are offered by banks or NBFCs (NBFCs stand for Non-Banking Financial Companies).
    Group credit life insurance schemes.

Conclusion

A decreasing sum assured is a viable alternative for individuals who want a lower premium but still seek peace of mind knowing outstanding loans are covered in case of their death. It reduces the financial burden on dependents and ensures that lenders receive the remaining loan amount. This type of plan also minimises the insurer’s risk. In short, it’s a systematic and practical insurance option for individuals with loans that reduce over time.
