If your family will have more than one student enrolled in college (for the year in which you will enroll), our calculator assumes that the additional student will be enrolled in a four-year private undergraduate college/university. For siblings enrolled in other types of undergraduate institutions (four-year public, two-year/community college, etc.), Columbia will adjust the Parent Contribution accordingly. Columbia does not include graduate sibling's expenses in our need-based evaluation.

Please input separate calculations with each parent’s information. The combination of the two results will be the total expected parent contribution. If either parent has remarried, your stepparent's information should also be provided. The calculated parental contribution will be based on both incomes; however, Columbia’s final calculation applies a proportional methodology to remarried parents.

We accept documents after the deadline without penalty. Please allow up to 8 business days for documents to be processed after you have submitted them to IDOC or Columbia. We ask that you do not resubmit documents as duplicate materials will delay processing.

To sign in please enter your Student ID (starts with the letter C followed by 9 numbers) and your Password (date of birth, MMDDCCYY format) in the 'Log-In' box. Do not use the 'First Time User' link even if you are a first-time user. Once logged in, follow the prompts to set up a new password and create security questions. If you haven't been assigned a Student ID yet, please contact your admissions office.
