If you have entered the workforce at 30 but have delayed investing by 10 years to build your retirement corpus, this 10-year gap can cost you as much as Rs 45.56 lakh. Before explaining how this figure has been arrived at, let’s first get a perspective of how seriously Indians take retirement planning from a study by Max Life. According to the India Retirement Index Study or IRIS 4.0 study, 44 per cent of Indians in the metro, tier I, and Tier II cities feel that the right age to start retirement planning is below 35 years. The research also indicates that 90 per cent of people aged more than 50 regret not having started retirement planning early.
