I'm sure this is a "serious," question. ....and no disrespect intended, but I did gasp when I read this. Even a "ball park figure" couldn't be calculated. My mind is reeling just thinking about it. The price of EVERYTHING fluctuates (mostly UP) in increments of years, so irradically......where do you live? What kinds of schools will your children attend? Activities, clothing, medical bills, food, athletics, entertainment, music lessons, danicng, gymnastics? Dental visits, pets, parties, proms, Sporting events, vacations, .......Save up for it? Really? If couples chose to SAVE UP for the total cost of raising a child, considering you are starting out as most average couples do (and you don't already have a small fortune in the bank)........You would be at LEAST 80 years old. Well past child bearing/rearing age. AND I AM QUITE SERIOUS. Maybe there's some website you can go to where some expert has taken the time and thought to try to figure this out......I can bet it wouldn't be correct anyway. There's only one way to know......and that's AFTER the fact, when you're sitting at home ....when the kids are grown and gone...and you're rolling pennies to pay the gas bill. and btw...they come BACK....with the grandchildren. Look, if you're planning on children....just have them.....and kiss your money Good Bye. That's my final answer. Good luck..
