Part 1. Today is my 50th birthday. I plan on retiring at age 65 estimating that I have another 25 years to live. In order to draw $150,000 each year over the next 25 years, how much do I need to have at the time of retirement? (assuming my retirement has a return of 10% per year)

Part 2. If I have 1 million saved now and made no further contributions with a 10% return, will I have enough to retire at 65?
