The Personal Finance section of Yahoo!Finance has many useful
calculators. A popular one is called “How much will I need to save for retirement?”. You input your assumptions and it gives you a chart and a spreadsheet of what your retirement balance should look like over the years. So let's see how much savings I need if I want to retire at say age 55.


The graph above shows that my retirement balance must be about $1.6M at age 55 to be able to enjoy 30 years of retirement with 75% income replacement.
The spreadsheet below shows my required savings for the next 20 years in order to reach a retirement balance worth $1.6M by age 55.

The bulk of the money comes from the interests. Being able to produce an 8% investment return year after year will be the most challenging part. Is this plan actually feasible?
