Retirement: How much will I need?

Each monthquarteryear I want to withdraw the equivalent of
in today's money.

I am years old and will start living on
my retirement assets when I am years old.

I will need to live on my retirement assets until I am years old.

I estimate that inflation will average % each year.

While living on my retirement assets, they will earn about % each year.

I will need to accumulate by the time I start living on my retirement assets.
