Jeevan Anand is a hybrid policy wherein at maturity the agreed amount is paid but the life cover would be valid until the death of the policyholder.
Any hybrid policy is not worth or rewarding when compared to a pure term policy and investment the rest in a MF. Please check that the term is over because such policies have a penalty based on the years you've paid the permium before encahsing.If you encash this in the first 2-3 years, you would lose heavily.
Premiums would be paid annually for the selected period for PPT premium paying term (20 years) in your case. People get confused with PPT and PT. PPT is the term for which you have to pay the annual premium. PT is the policy term (this is the life cover of sum assured for a total of hundred years)
If a person (26 years) had taken a policy in Jeevan Anand in the year 2010 for 25 years, The first maturity will be at the end of the PPT, 2034 in this case, the second maturity of life cover will show as 2084.
Bonuses will be declared, but the person will receive it only at maturity or death. Please remember there is no guaranteed that bonus/sum assured will be what is mentioned at the time of taking the policy.
You have taken the policy with Rs 1 lakh. If you have paid the annual premium for 20 years (roughly Rs.5550/year), then you would get the end amount on maturity (after 20 years) which would be Sum Assured + Bonus declared (around 45-47 rupees/thousand/year). So you should be getting around 1.95-2 Lakhs in hand after 20 years.
The good thing about Jeevan Anand is that even after the policy matures the life cover carries on until the death of the policyholder.
To get the claim of maturity, LIC would intimate you 2 months in advance from the date of actual maturity.
You will need the original policy.
