Lots of things don't add up here.  I would suggest...

1) Get a handle on current expenses by tracking them monthly.
2) Prepare a budget based on "1" and try to live by it.
3) Prepare an expected assets plan based on current assets and future expected savings.  Use a conservative appreciation rate.  (I use 4%.)
4) Prepare an expected cash flow plan for retirement based on "1"

When "4" exceeds "2" by about 10% you will know that you can retire if you wish.  Why 10%?  Because shxt happens.
