My question as well. I have seen some terrifying figures for how much it cost to bring up a single child through college years.
You can spend as much or little as you like. There’s a whole lot of “free” (and very inexpensive) out there, if you’ll just decide to focus on using those impressively extensive resources.
As for college: my wife & I have 5 degrees, total cost under $150k, paid up front in cash. Lots of ways of not paying list price.
Out of the 10 kids, seven graduated from college having started out in community college. Four went on to receive higher degrees.
None of us went to Harvard, and none of us have spent time in jail. All of us are tax-paying citizens.
BTW - none of us got free rides through college. We all paid our own way, mainly because mom and dad could not help us.
So, it is possible to have children and send them to college with having to experience terrifying figures.
If you want more than the standard two or three kids have them all and show your kids how to be frugal and responsible with money.
