The need for life insurance is based on various factors, including your current lifestyle, expected outflows in future, your present age and your family size. The first step should be to estimate how much financial support your dependents would need to continue to enjoy the same lifestyle as they enjoy today if you are not around to provide that support. In estimating this support, you should consider all regular monthly expenses, including food, rentals, conveyance, school fees, medical expenses, any debts to be repaid, etc., and also estimated ones like children's education and marriage and your expected needs after retirement. Always provide for unforeseen contingencies that your dependents might need during the period of adjustment. Based on this analysis and the expected returns on the investments in future, you can work out a sum of money that would help your dependents achieve financial independence even if you are not around to support them. While every individual's situation would be different and should be evaluated separately, one rule of thumb is to buy a cover for an amount equal to 6-10 times your annual income. The need for insurance is not static and will change as your life stage changes, so you must re-work the requirement periodically and review the coverage available occasionally. It is advisable to speak to a trained financial consultant/insurance advisor to determine the extent of coverage that you require.
