Please find below a calculation which i have done by using an excel.
There are some LIC Agents who are selling insurance plans called Magic plan-Retire and enjoy.I have proved here that my investment idea can beat their so called magic plan hands down.Below is the sample illustration for a person aged 26 years and planning an investment of 1 lac approximately every year for his retirement planning.
I have named it "Baap Of Magic Plans"...

Hope you all will like it.
Investment type-Traditional/conventional
Market exposure- No
Investment amount - 1.05 + 0.05 lac per annum
Total investment amount - 1.1 lac per annum
Investment period - 1.05 lac for only 15yrs!!! and 0.05 lac for 30yrs.
So total investment amount from you is only Rs.1725000/-!!!!!
Expected return on Investment - From your 56th birthday you can take
home 10lac!! every year as a pension amount till your 80th birthday
and once you reach your 80th birthday you can take home 12 lac
approximately as a lump-sum and the plan will get closed.
Death Benefit - In case of death before your 56th birthday,your family
will receive 30 lac insurance money plus the accumulated money in the
pension fund.
For example - In case if death happens on 50th year,your nominee will
receive 30 lac insurance money plus 50 lac approximately from your
pension fund!!!
In case of death after 56 the birthday,your family will receive 12 lac
plus remaining balance from your pension fund.
For example - In case if death happens on 65th birthday, you would
have received 10 lac for 10 years as pension,so total 1 crore you have
used for yourself and your nominee will receive 12 lac insurance money
plus 85 lac approximately from your pension fund.
I have suggested you an investment theory which is absolutely
conventional and secure.You have to just invest in 3 different plans
to get these benefits.
Do let me know if you would like to take this for yourself.
