1 The cost of daycare can vary greatly from state to state and city to city. 2  Generally speaking, the busier the area, the more expensive the daycare rates will be. 3  According to babycenter, day care costs can average anywhere between $250 and $1200 per month. 4  The average national monthly cost of child care is $611. Larger chains such as Kindercare may cost more than a local daycare center. 2  For example, a Kindercare may ask for $280 to $350 per week while a local no-name center could be near the $180 to $250 per week mark.
