GDP can be contrasted with gross national product (GNP) or, as it is now known, gross national income (GNI). The difference is that GDP defines its scope according to location, while GNI defines its scope according to ownership.
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).
For each mile you drive across two times on your round trip to work daily, it multiplies to 500 miles per year, or a $170 annual fee. For each of these miles, you waste about 6 minutes in the round trip, adding to 25 hours per year ($625 of your time). So each mile you live from work steals $795 per year from you in commuting costs. $795 per year will pay the interest on $15,900 of house borrowed at a 5% interest rate.
