What a First-Class Stamp Cost in 2018
In 2018, the cost of a single First-Class Mail Forever stamp issued by the United States Postal Service remained flat at US$0.55, unchanged from 2017. Two-ounce letters required an additional ounce stamp, typically adding another $0.15 in combination, while larger or heavier items were priced by weight and zone. These prices reflected continued pressure on mail volumes and the postal network’s operating structure. The following breakdown explains who sets U.S. postal rates, how 2018 compared with recent years, and what the numbers imply for sending mail and parcels.
How U.S. Postal Rates Are Set
The Postal Regulatory Commission (PRC) reviews proposed rates for the U.S. Postal Service and decides whether to approve, modify, or reject them, aiming to balance revenue needs with public interest. The U.S. Postal Service then implements these rates on set effective dates, often in January and June. Increases are typically tied to inflation as measured by the Consumer Price Index, operational cost trends, and changes in mail volume, with different product categories—such as letters, flats, and packages—priced separately.
Postal Pricing Basics
- Forever stamp: covers the price of a one-ounce First-Class letter when issued; additional ounces are charged via extra stamps or other designated products.
- Postcard: has a separate lower rate, often cheaper than a letter.
- Additional ounce stamps: used to cover increments beyond the first ounce for letters.
- Large envelopes (flats) and packages: priced by weight, dimensions, and destination zone, with automated and manual processing affecting cost.

2018 in Context: How Prices Compared with Earlier Years
By 2018, U.S. postal rates had risen modestly over the prior decade but remained near the low end of recent history in real terms. Between 2008 and 2018, the First-Class stamp increased from $0.42 to $0.55, reflecting both operational pressures and the PRC’s cautious approach to price adjustments. The decision to leave the rate unchanged in 2018 followed a January 2018 increase that had already set the stamp at $0.55, and it signaled a temporary pause as the postal service continued to manage volume declines and cost pressures.

What the 2018 Price Meant for Senders
A 2018 First-Class stamp at $0.55 covered a one-ounce letter; heavier correspondence required extra postage in the form of additional ounce stamps or higher-rate services. For packages, Zone 1–2 retail First-Class Package rates hovered near $5.80–6.40, while Priority Mail for a 1 lb zone 5 package was approximately $7.95. Businesses and frequent shippers often mitigated cost through metered postage, bulk discounts, and nonprofit or commercial pricing programs, which could lower effective per-piece costs compared with standard retail rates.
International Context and Alternatives
Compared with many other countries, U.S. postal rates in 2018 were moderately priced for letters but relatively higher for small packages. International First-Class and Global Express rates varied widely by destination, with small letters often costing significantly more than domestic rates. Many senders offset these costs by using flat-rate envelopes, which bundled packaging and transport into a single price, or by shifting non-urgent correspondence to email and private courier options where viable.
