The professor of São Paulo School of Economics (FGV/EESP), Samy Dana, analyzed in his column Caro Dinheiro, for the newspaper Folha de São Paulo, the need to purchase a life insurance.According to the latest survey of the National Federation of Life and Private Pension Plans (Fenaprevi), the turnover value for this busy market increased by 13.6% in November 2013 compared to the previous month. In addition, insurers paid 495.6 million in damages - which is 7.04% more than they paid in November 2012.However, although necessary in some cases, Samy states that spending on insurance may seem like a waste of money for many consumers. According to him, life insurance is recommended only for those who have dependents, whether children or not. For those who don't, a financial reserve or disability insurance is enough.If the purchase of a life insurance really applies to the situation, the professor observes the importance of evaluating and comparing prices and benefits. The best alternative, in his opinion, is to make a simulation on how much each dependent would receive per month in case of death.Samy reinforces that the life insurance only pays off if the dependents receive enough income to pay for their bills. The plan is to assist the dependents, saving them from financial problems in your absence, he says.
