What are your metrics for progress en route to FI? There are occasionally threads on various metrics, and I though it would be nice to have a one-stop list of those, and discussions of the relative merits.
A few that come to mind include:
- Savings rate (%you sock away out of your income)
- $ invested in today dollars to get one day of FIRE (i.e., I socked away $2k and at my projected expense rate, that will be FI for one day for the rest of my life).
- Annual savings rate relative to Annual FI spending (i.e., annual investing of 20k with expenses of 40k would be 50%)
- % of FIRE (how big is you nest egg relative to your target)
- FIRE date: at your current investment rate, what year will you FIRE?
Suggestions for others? Thoughts and musings? Fun ones? Metrics you see bandied about that you think are bogus?
