Purdue OOS COA is $40-42K/year depending on housing selection. UMD may be closer to $45K but they are a bit more generous with merit.
Editing to add - OP - are you an international student or domestic student? I’m unclear since there was an implication that you are in state for WA.
If international, than Purdue will be $45K/year as there are some extra fees for international students. Unsure about UMD.
