Also keep in mind that you might be able to live a perfectly satisfying life without replacing even half your current income. Track your spending, not your income, since right now you are probably paying a lot of income tax that you won't be paying when you stop working. If you can replace the amount of spending you want to support, then it doesn't really matter what percentage of your current income that becomes.
