Jack and Jill Johnson are preparing for their son, Josh's (age 8), future education. They anticipate that Josh will start college at age 18 and pursue a 4-year degree. College education costs are currently $25,000 per year, and the Johnsons expect these costs to increase annually at a rate of 6 percent.

The last deposit will be made when Josh turns 18
