How Much Do You Need To Pay To Mail a Letter?

While the cost of mailing services depends on multiple factors, mailing a standard First Class Mail letter is affordable. If your letter has up to four pages and weighs no more than one ounce, you’ll pay only $0.55.

The heavier and larger the envelope is, the more expensive your postage will be. The price will also increase if you choose the Priory Mail or the Priority Mail Express over the First Class Mail.

You can use an online calculator, or you can check the price in the post office directly.
