Cost of Attendance

2023-2024 Estimated Academic Year Budgeted Cost of Attendance

The estimated Cost of Attendance (COA) is a budget that includes categories of expenses that a student can expect to incur while attending college. The COA does not reflect actual charges. It is an average based on the estimated living costs typical of our region. In determining the cost of attendance, Northcentral Technical College uses the budget established by the Wisconsin Technical College System (WTCS) Financial Aid Budget Work Group. This budget is used to determine financial need for all students who apply for financial aid. A student's cost of attendance is composed of all educational expenses that can be included for financial aid purposes that a student may accrue while pursuing their education for the year (or semester, if enrolled less than a year). A student's financial aid cannot exceed their cost of attendance. Schools are required to provide a fuller picture of what it may cost students to pursue their degree, not just what they will owe in tuition/fees and books/supplies.

Please Note: this COA budget estimate assumes full-time attendance for two semester Fall 2023 and Spring 2024.

Students with dependent care, computer or study abroad expenses should contact the Financial Aid Office to document allowable expenses which may serve to increase their COA.

Students awarded Federal Direct Loan(s) also have an average of the mandatory loan fees automatically added to their COA.

Students with disability-related expenses may contact the Financial Aid Office to have their additional expenses considered. Disability-related expenses include but are not limited to: personal assistance, equipment, and supplies. The Financial Aid Office may potentially include disability expenses in the COA that are not provided by other assisting agencies.

NTC also offers a Net Price Calculator to help estimate costs.
