I guess you’re considering living w/out a saving would be comfortable but when I have about $10k/month in expense, I won’t be comfortable until I have at least $60k in savings for the rainy day fund. $120k would be preferred. By your calculation, at max, you can only save $1800/month. That hasn’t count in car maintenance, insurance, presents, vacations, etc. yet. I guess everyone have a different definition of comfortable.
