Here are a few calculators I have developed to help me with financial and estate planning.  They will answer the key questions: How much will I need in order to retire?  Will I have enough to retire?  How much will I need to save so I can retire?    What is the cash flow and return on a real estate investment that could be part of my portfolio?   In addition there are some basic concepts regarding investing that everyone should know. (Calculations and advice are believed to  be accurate. Jay McNamara is not to be held liable for any losses due to the use of these calculators or advice.)
