I’m not sure why Earlham was used as an example of a low endowment school. On a per student basis its endowment places ~30% higher than, for comparison, the quite respectably resourced Wesleyan’s (at least by the figures I accessed). In any case, IPEDS might offer you a preliminary sense for the net cost of various colleges for your financial situation, @ArtsyKidDad (e.g., https://nces.ed.gov/collegenavigator/?q=Earlham&s=all&id=150455#netprc).
