I am planning to retire in 10 years. I want to have enough saved so that I can withdraw $2,000 per month each month beginning on the day I retire for the next 25 years. During my retirement account I will invest in a conservative account paying 8%. Between now and when I retire, I will make end of each quarter payments into an aggressive account that will earn 10% compounded annually. How much must I put away each month to meet my goal?
