I pay around that per month, but that includes all of my expenses, including rent and other bills, not just credit card alone. Maybe the person you're responding to has kids or lives in a higher COL area or something.

In some places, rent alone might be that much though.

Rent for a 1b apartment is more than that in some cities in California.

Edit: I see this was responding to someone spending 2.6k just on their credit cards, apologies. When I just graduated, spending that much on a credit card seemed like a lot of money. Now, that's just average ... on one credit card. Try having a family, traveling, or ... I don't even know, but life catches up with that pretty quickly.

It's not usually that high but it's not totally uncommon for me to spend that much a month. I usually try to keep my spending between $1,200-1,800/month but that doesn't always happen.
