Determine the pitch of the roof. The pitch is how steep the roof is. Pitch is calculated by the roof's rise over its run. Measure from the edge of the roof over 12 inches (12 is the run) and see how many inches up the roof line is (this is the rise). Get a slope multiplier from the chart below.
Quick Answer. According to the U.S. Postal Service, the price of a first-class postage stamp in the United States is 49 cents as of June 2014. This rate applies to standard-sized mail weighing 1 ounce or less. Letters weighing more than 1 ounce cost an additional 21 cents to mail.
Once the USPS reaches that ceiling, it is required to roll back the 4.3% surcharge it had tacked on to first-class mail and commercial postage rates. That means that the cost of a stamp to mail a standard letter will decrease from 49 cents to 47 cents this Sunday. The price of sending a postcard will also drop by a penny, to 34 cents, while international mail will go down by a nickel, to $1.15 per letter instead of the current $1.20. While the price cut will be a boon for many consumers, itâs bad news for collectors and investors in so-called âForever stamps,â the generic stamps valued at whatever the current postage rate is no matter when they were purchased.
