For Skidmore your EBRW is well below the 25% level (p 10, #9 on the 2017-18 CDS), but your TOEFL score is very good…did you submit TOEFL to Skidmore?
Skidmore provided on average $64K of fin aid for 83 international students, per page 23 of the CDS (H6). https://www.skidmore.edu/ir/facts/common/CDS_2017-2018Final.pdf
Skidmore’s COA for 2018-19 is $68,764 (with lowest cost housing). https://www.skidmore.edu/bursar/cost.php Assume a 3% increase in costs for next year.
On top of that you will have expenses for books, activity fees and $2,360 mandatory health insurance, so count on another $4K in expenses. Also you will have to add costs for international travel to and from home. That all could work (but tight), assuming your family qualifies for need based aid at the average level of $64K.
Where else have you applied? Have you run the NPC calculators on the websites of the schools you have applied to? Not always accurate in every instance, especially for international students, but could be helpful nonetheless. All schools will take into account each family’s income, and some assets, when calculating how much each family can pay. The inputs, calculations and final number can vary from school to school.
Good luck and you should find out soon at least with respect to Skidmore admission, not sure when the fin aid package will follow if you are accepted.
