Build the twelve-month cost
Use the same time period for every option.
- Housing paymentsInclude all rent installments, premiums, mandatory fees and any summer months.
- Move-in cashList application, holding, security and utility deposits plus first payments.
- Monthly operationsEstimate electricity, gas, water, trash, internet, insurance, laundry and parking.
- TransportationPrice transit, fuel, parking permits, maintenance and trips when campus service is not running.
- Household setupCount furniture, cookware, cleaning tools and shared items not included with the unit.
Subtract what the move replaces
Avoid counting the same expense on both sides.
- Campus housingRemove the room charge only if the private lease covers the same full period and cancellation is confirmed.
- Meal planCompare a realistic grocery and occasional campus-food budget with the plan you can actually drop.
- Campus transportKeep fees that remain mandatory even if you commute differently.
- Included servicesAssign a value only to services you would otherwise pay for, such as furniture, internet or utilities.
Stress-test the cash flow
A lower annual total can still be harder to manage if deposits and first rent arrive before financial aid or summer income. Map when each payment is due and whose account will cover it. If roommates split shared bills, decide how an empty bedroom or late payment changes everyone else’s obligation.
Run a higher-utility month, a transit interruption and one roommate leaving. The goal is not to predict every problem; it is to learn whether the plan has enough margin to survive a normal surprise.
Compare one final number
End the research with a decision your household can explain.
- NormalizeConvert every option to the same lease period and occupancy assumption.
- Time paymentsPlace deposits, rent and expected aid or income on a monthly cash calendar.
- Add a bufferChoose a specific amount for utility variation, repairs, travel and replacement items.
- Document the splitRecord how roommates divide fixed, variable and one-time costs before signing.
