How do i know which college will be cheapest?

I just saw on the bottom and it said

You have accepted UGA’s Terms and Conditions. To accept or decline your Financial Aid Award click the Accept Award Offer tab above, if applicable, otherwise click the Award Overview tab.
Note: Estimated awards require no action on your part. Only Official Awards can be accepted or declined. Gift aid which includes scholarships and grants will be pre-accepted for you.

there is not “Accept Award Tab” and when I go to “Award Overview” it says the loans are estimated and the grants are accepted. So this means Im good right? I have not accepted any aid is this correct? thank you to everyone that has helped
