Car Rental Analysis

Personal Transportation or Rental Vehicle: Which is more cost effective?
Notwithstanding an individuals personal preference, availability, leave time, etc., the following break even analysis can be used to help determine the least expensive choice for your department and CMU.  

One Day Trip Analysis: The analysis compares:

  1. A full size car rental from Enterprise (currently $36) 
  2. Using the CMU Business MasterCard which includes collision insurance
  3. Gas at .205 per mile, (based on $4.10/gallon and 20 miles per gallon)

    Against being reimbursed at .505 cents/mile (CMU's current rate).  

  • Less than 120 Miles Round Trip:  Personal transportation is the least expensive.
  • Over 120 Miles:  Enterprise is the least expensive
