Bug in calculation
I put in the following values:
Current annual income: 434782
Current annual savings: 334782
Current annual expenses: 100000
Current savings rate: 76% (calculates automatically)
Current portfolio value: 850000
It says I can retire in 4.3 years. If I add ONE dollar to annual income and recalculate it says i can retire in 3.8 years with a 78% savings rate. That's a huge jump for 1 dollar.
As another example if I put in 400,000 for income it now says I can retire in 4.1 years. Meaning that making over 30,000 less would result in an earlier retirement date.
