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).
Putting those costs in terms of an average commute to work, the driver of a medium sedan who pays 52.5 cents per mile spends $10.50 to make a 20-mile round trip each day. The tab comes to $52.50 in a five-day week. Multiply that by 50 weeks per year and the grand total comes to $2,625.
