Calculate Your Cost of Commuting. Fill out this form to figure out your monthly commute cost! (Press TAB to move to the next field and SHIFT-TAB to move back one field.). In order to calculate Monthly cost of commuting please use this formula: monthly cost = ((distance * workdays * 0.065) + (distance * workdays * 0.46) + (distance * workdays * (price / mpg)) + (parking)). where: distance: your daily round trip commute distance from home to work (in miles).
An alternative approach is to divide the $3.75 average parking space cost by 22 average commute miles and subtract 8% for commuter paid parking, which gives an estimated average external commute parking costs of 15.7Â¢ per commute mile. Based on these estimates, 15Â¢ per commute mile is used for Urban Peak driving.
