I'm constantly playing with a spreadsheet to project when I can FIRE. (I also use FIRECALC, but like to play with the spreadsheet too.) I'm curious what people use for their assumptions. Mine are:
- Return before FIRE: 6.5%
- Return after FIRE: 5.5%
- Inflation: 3%
- SS COLA: 2%
- SS factor: 85% (figuring govt will take 15% of mine)
