How It Works
How to Compare Room & Board Costs
Compare on-campus and off-campus living costs for the academic year.
Formula
Off-Campus Annual = (Monthly Rent + Monthly Food) x Academic Months
Savings = On-Campus Cost - Off-Campus Cost
Positive savings means off-campus is cheaper. Include utilities, commute costs, and meal plan value for a full comparison.
Worked Example
On-campus costs $13,000/year. Off-campus rent is $800/mo and food is $350/mo for 9 months.
- 01Off-campus annual = ($800 + $350) x 9 = $10,350
- 02Savings = $13,000 - $10,350 = $2,650
- 03Living off-campus saves $2,650 per year
