Just after the New Year, the price of a first-class, forever stamp will increase 10 percent.

Beginning January 27, the price of a first-class stamp will rise from $0.50 to $0.55. The cost increase is the largest increase in USPS history.

The increase in stamp prices, along with increases in other USPS shipping pricing, comes after the agency announced losses of $3.9 billion during fiscal year 2018.

The postal service has seen increases in package delivery revenue, but still has experienced significant declines in domestic letter and direct-mail advertising volumes. The losses have caused President Trump’s administration to suggest the agency should be privatized. The White House later backed off that stance

When the rate increases go into effect, domestic, first class postage will change as follows:

Product	Old Rate	New Rate
Forever Stamp	50 cents	55 cents
Metered Letter	47 cents	50 cents
Additional Ounce	21 cents	15 cents
