The price of attendance listed on the Tufts website is the cost of attending Tufts without financial aid. In order to estimate estimate of the amount of financial aid you may be offered if you are accepted to Tufts, you can use Tufts’ Net Price Calculator, hosted at the College Board.
Note, the estimate of your aid award provided by the Net Price Calculator is based on a standard formula. However, special circumstances can be considered by the Tufts Financial Aid Office on a case-by-case basis. If your situation is unusual, you may want to contact the Tufts Financial Aid Office after you are admitted.
