Other factors that affect the postage rate are quantity, the sender's non-profit status, delivery speed and the mail entry point. Bulk mailers also need a permit and must pay an annual mailing fee per class of mail.

In general, the USPS determines postage rates by considering the balance between the value a sender obtains from using its service and the amount of work the sender does to prepare the mail or parcel. Therefore, the more work a sender does, the lower the postage rate. This way, the USPS saves on labor costs that it passes onto its customers in the form of good commercial rates.
