How Much Does Mail Cost? 'Forever' Postage Rate Increase Comes After Recent Stamp Decrease

The U.S. Postal Service has planned to implement new postage rates for several mailing and shipping products over the weekend, USPS said. It will again cost consumers 49 cents to mail a 1-ounce, first-class letter in the U.S. The price increase takes effect Sunday.

Last April, the cost of a first-class Forever stamp decreased to 47 cents after the Postal Regulatory Commission ordered USPS to drop its rates in October. The decrease was the first reduction in pricing in 97 years.
