FIRE target number
Financial Independence Retire Early (FIRE) target number is the year (or how many years) I reach financial independence and there is no need to work anymore. Normally is the year when my total balance reaches 25 times my yearly spending.
It would be nice to be able to see how my spending would impact this number. There are many Monte Carlo simulations on internet to calculate the FIRE number, based on current spending (non-work spending). It can even be used as part of gamification to help user to spend less and invest more.
It would really help us, user to improve our savings rate and build up more wealth.
