Add ability to to categorize mortgage as "expense" rather than "debt"
The way you currently factor in a mortgage makes sense logically, but some people approach mortgages a bit differently in regards to calculating FIRE, and it would be cool if this tool supported more flexibility in that regard.
What I feel is missing is a way to categorize your current liquid net worth, WITHOUT factoring in the mortgage debt.
In some FIRE calculations, the mortgage payment is simply an expense that the total investments need to cover. So you would be FIRE if your total investments are 25x (your expenses + your annual mortgage payment).
Currently I can have a “FIRE” milestone be triggered if either my Total Net Worth or Liquid Net Worth reach a certain level, but both of those factor in the negative amount of the debt, so it doesn’t seem possible to calculate FIRE in the way I described above.
