In my family, we had four boys swimming competitively. So that's club fees for four, plus 20000 calories/day total if you figure each parent at 2k and each kid at 4k. My parents also paid for car insurance, which may as well be paying college tuition when you've got four young male drivers in the house.

So those are some ways. Paying for phone plans (my parents didn't) could also get expensive, as could clothes if they don't have to buy their own.
