The cost of raising a child actually changes as they get older. Using the breakdown provided by the Child Poverty Action Group, parents in the UK can expect to be spending £295.72 ($343.06) per week while they’re a newborn; roughly £1,200 ($1,395) per month. As they hit 18, however, it more than halves to £94.63 ($109.78); less than £400 ($465) per month .
The US figures, however, says the total spends averages a whopping $18,000 every year, which works out at roughly $1,500 each month.
