Years til FI Calc

[newton86]

I'm familiar with the math MMM came up with regarding your savings % and its correlation to year until FI. However, that assumption assumes that you are starting with 0 NW. Does anyone have a formula that calculates years until FI based on current savings % and $xx NW?

Another example of a question answered before. I wish forums made it easier to surface the most-wanted content.
