The cost to send mail is going up. The U.S. Postal Service announced they will raise the price of a postage stamp from 63 cents to 66 cents on July 9.

The Postal Service said the rate increase is part of its 10-year plan for achieving financial stability.

“With full implementation, the 10-year plan reverses a projected $160 billion in losses over the next 10 years,” the Postal Service said in a filing with the Postal Regulatory Commission, which had to approve the price increase.

The cost to send a postcard will also increase. The fee will go from 48 cents to 51 cents.

Postcards and letters sent internationally are also subject to a 5-cent increase — going from $1.45 to $1.50.

Businesses will also see an increase with a metered mail price hike. Their rate climbs from 60 cents to 63 cents.
