The Cost of Raising Children Calculator helps you estimate the cost of raising your children from their current age to age eighteen. This calculator uses data from the report, “Expenditures on Children by Families, 2004” (miscellaneous publication number 1528-2004) published by the Center for Nutrition Policy and Promotion of the United States Department of Agriculture (USDA). Using the footnotes provided in the report, costs are adjusted based on whether the family is a single- or two-parent family, based on income level and based on number of children.
