I don't believe that there is a "perfect" budget for everyone. Maybe you have an extremely small housing payment, but very high medical expenses.... but this graph is a good starting point. How does your budget compare to the suggested one below? I definitely agree with the savings section below. I am making a large effort to explain to my children (and anyone else that will listen) about the importance of savings. Saving for an emergency, saving for retirement and saving for a home purchase. Imagine the following scenario...

Starting with $0 and depositing $100 monthly over 65 years (at a rate of return 8% compounded monthly), you will save $2,296,847.
Initial balance: $0
Total deposits: $78,000
Total interest earned: $2,218,847
Total taxes paid: $0
Total Saved: $2,296,847

Now that really makes me want to save not only for myself but for my children! Even with inflation, that would really help with their retirement. I would hope they would have separate 401K's or IRA's too... regardless sometimes you need a visual push to get you to save.
