USPS adjusts Mailing Services product prices based on the Consumer Price Index. Shipping Services product prices are adjusted according to market conditions while reflecting the need to maintain affordable services for customers.

The Postal Service is completely self-funded and doesn’t receive tax dollars for operating expenses. Instead, the organization relies on the sale of postage, products and services to fund its operations.
