bug in time estimate?
I think something's wrong with the timeuntilretirement estimate, or there's something i'm misunderstanding.
I entered $100k income, $75k expenses, and $1m portfolio, and got this result:
It looks like the ROI reaches $75k shortly after 6 years, but the timeuntilretirement is over 9 years. The table of figures stops updating some but not all of the columns after 6 years. A glitch?

fwiw, I finally open sourced the site: https://github.com/kablamo/Networthify

I noticed the exact same thing. The graphical representation does not match the written one.
The figure shows that I reach retirement a couple years BEFORE the numerical one does...

Hey those are really good ideas. I don't have a repo for this. But I totally should. I'll try to make that happen tomorrow. I'll update here when I do.

That makes sense, thanks for clearing that up for me.
I think the "Percent Of Expenses Covered By ROI" column threw me off, the number i was expecting was really "Percent of Expenses Covered By Withdrawal Rate" and i didn't look close enough.
Some suggestions to make the table clearer:
* Have the Expenses and ROI columns extend down all the way (mine end as soon as ROI reaches Expenses).
* Replace the "Percent Of Expenses Covered By ROI" with "Percent Of Expenses Covered By Withdrawal Rate".
* Add a "Income from Withdrawal" column that starts at retirement.
* Add a "Amount of ROI reinvested" column.Is there a repo somewhere with the code? I could add those features if you think it'd be useful.

Thanks for commenting! Good question. Its not a glitch. Its because you're withdrawal rate is less than your rate of return.
Your withdrawal rate is 4% and your rate of return is 5%. So at 6 years you are making 75k every year due to your 5% rate of return. However you're withdrawal that year will be less than 75k because your withdrawal rate is 4%.
5% of your nest egg = $75k.
4%of your nest egg = some number less than $75kIn other words your nest egg isn't big enough to cover your expenses yet.
