Words to know

grant / scholarship: Money given toward college that is not paid back.

family contribution: The part of the cost the family plans to pay.

simple interest: Interest earned only on the amount borrowed, the same each year.

rise: How much a price goes up from one year to the next.

Common mistakes

Your child used the first year's price for every year. When a price rises each year, each year has its own cost to add up.

Your child added a rise to year 1 as well. Year 1 is the starting price; the first rise happens in year 2.

Your child used year 4's price for every year. The price is lower in the early years, so the total is smaller.

Questions parents ask
