It's no secret that kids cost money.

But how much do they really set you back?

For the average American parent, raising a child comes with a price tag of at least $12,980 every year. By the age of 17, that’s well over $230,000—and that’s before college costs come into play. High-earning families spent even more—over $370,000 according to the research.

Of course, child-rearing costs vary from family to family, and it’s far more expensive to raise kids in some high-cost-of-living states, like Oregon and New York.

Plus, kids don’t magically stop costing you money once they turn 18. College, rent, insurance, and helping out adult children can all add up.
