how much would your 401k provide monthly

[RunHappy]

I found this fun calculator to help show how much monthly income your 401k would provide.  It only takes into account 401k, not other investments or other retirement accounts.

This thing gives you wildly high monthly income estimates.  7 to 8% withdrawal rates!  You're at risk of burning through your money if you hit a flat spot in the market at those rates.  The calculation of the ending value is right but I wouldn't use the income estimates.

yeah, I prefer to use this one, inputting my own SWR (3-4%) or a monthly value, to see how it fares given certain inputs (inflation rate, rate of return, taxes):

With a 3-4% rate, you know based on Bengen/Trinity Study it's got a very high probability of surviving based on past history, though of course the final balance after 30 years is dependent on a lot of factors (one does not earn a steady rate of return over the period, but rather it can fluctuate wildly from year to year).  A useful tool is all.
