OK finished reading your post......
You income and your spending are NOT RELATED! don't think of it as a percentage like savings rate, think of it in total doallrs spent for your expenses, and then minimize that number within reason. What you make has nothin' to do with it. if you are making 70K-80K your have the opportunity to be FI rather quickly, don't jeapordize it by frivolously wasting money just because you can..... you live with a roomate-GOOD, but 2200 seems like a lot, where do you live? My mortgage is 820/month, my wife and I split that..... given the current environment, most people who can buy a house or condo or apartment and also rent out the extra rooms are living rent free as the roommates pay for all or most of the mortgage. Do you live with your girlfriend? if you are serious about marriage within the next coupla years, the roomate you mention might be your girlfriend, we just don't know.... you might want to consider buying a house that you ultimately will live in in several years, but we don't know enough details so it might be the worst thing to do right now.... who knows, tell us more...
Based on your list of expenses, your yearly expenses are just over 28,000. That is about what my wife and I spend total, so double per person than what I do but you might live in san fran or NYC or somewhere expensive, so who knows..... tell us more. but I bet if we can delve into the details a little bit more, then we can adjust your yearly expenses down a bit, and get you to FI that much faster!
Just remember that your income and your expenses are NOT related, jsut because you make a lot of money doesn;t mean you should be spending it on frivolous things that only delay your FI date.... Tell us where you live, what you do, you car loan details, your roomate sitch, and your fiance-to-be details and we can help you better.
Cheers,
Scott
