A rough calculation of the surrender value of LIC policy after 3 years is given below:

Let's say, you are paying Rs 90,000 annual premium. You paid it until 4^Th year and then decided to surrender the policy.

Total premium paid excluding 1^St year = Rs 2,70,000

Therefore, the surrender value will be total premium - 30% of premium paid i.e. 30% of 2,70,000 which comes up to Rs 81,000.
