You want to begin a saving for your retirement. You plan to contribute 12.000 to the account at the end of this year. You anticipate you will be increase your annual contributions by 3% each year for the next 45 years. IF your expected return is 8% (A.c.a), how much do you expect to have available for the consumption every month (suppose a constant amount of money every month) if you are planning to live 30 years more after retiring?
