I just did the math after reading this thread.
Our mortgage is roughly 27 percent of our take home income.
That does not include utilities, gas, groceries, daycare, car payments, car insurance, etc. When you add all that in, it takes up about 65 percent of our take home income.
We do not have a fancy house or fancy cars. Our grocery bill is less than $500/month for three people. We do not have money for big vacations (weekend roadtrips are about all we can manage). I feel like we live a pretty basic but mostly comfortable life. Still, I wonder what I'm doing wrong when I see people go on 4-5 big vacations a year.
