How to estimate my future expenses?
Hi, I’m 27M, Single, LCOL in the U.S.
Income: $100,000 / yr
Expenses (not including investments): ~$35,000 / yr
401K: $115,009
HSA: $7,500
ROTH IRA: $40,000
Brokerage: $170,000
Real Estate Equity: $33,000
Debt/Mortgage: $119,000
I have been trying my best to invest in my 401K, HSA, IRA, and personal brokerage account so I can FIRE by 50 at the latest. Though I have a good idea of my expenses right now, it is hard to estimate them ~23 years out especially with planned life events: getting married, kids, buying a house, etc etc.
What are some tips that have worked for you to estimate that far out in the future given the uncertainties of future tax rates, inflation, currency fluctuations, etc. Any advice, resources, and tips are welcome and appreciated.
Thank you!
