How should I compare the affordability of Columbia and WashU after financial aid?

Compare Columbia and WashU by building a four-year net-cost estimate from the actual award letters, not by comparing tuition or the headline “total cost of attendance.” Start with each school’s billed charges, subtract only grants and scholarships that do not need to be repaid, then add realistic personal expenses, travel, and any borrowing your family would need. Columbia’s New York City location can make discretionary spending and travel more consequential, while WashU students may find St. Louis day-to-day costs easier to manage, even when the official budgets look similar.

For Columbia, pay particular attention to whether the aid package covers the full demonstrated need your family expected and whether it includes federal work-study, student loans, or a parent loan assumption. Work-study is an earning opportunity, not an automatic tuition discount, so do not subtract it from your bill unless you are confident you can earn that amount without compromising your academic adjustment. Include flights or train trips home, winter clothing, and the higher likelihood of off-campus spending in New York in your personal budget.

For WashU, examine whether its grant aid leaves a lower predictable family contribution and whether housing, meal-plan, health-insurance, and transportation assumptions match how you would actually live. St. Louis can reduce incidental costs, but the important figure is still the amount your family must pay or borrow after institutional, federal, and outside aid. Also check whether a scholarship is guaranteed for four years and what academic or enrollment conditions apply.

For both offers, separate grants from loans, work-study, and one-time awards; verify whether the listed parent contribution is realistic; and project annual increases in tuition, housing, and family income. A useful final comparison is: cash your family can pay each year + required student borrowing + likely parent borrowing + uncovered expenses. The lower number is the more affordable offer, unless the difference is small enough that a clearly stronger academic, personal, or career fit justifies it.
