Colorado uses a Schedule of Basic Child Support Guidelines, which is calculated on the incomes of both parents and the cost of day care. In Colorado, child support must be paid until the minor child reaches the age of 19, or graduates from high school, whichever comes later. The court may also require that the parent pay for college after age 19, but these payments will not be made to the parent with whom the child lives. Instead, child support payments after age 19 go to the child or the college.
