USPS® Rates to Increase for a Second Time This Year – Biggest Increase in Over 10 Years

The USPS approved the largest rate increase in over 10 years, and it is the second increase of 2021!  It also impacts the largest mailers the most due to higher percentage increases for production mail categories.

Postal Advocate has been creating comparison charts for our clients that go over the changes in rates to show how it will affect budgets. The reason we do this, is to provide a true comparison versus the overall average % increase that the postal service talks about. This is the second increase to happen in 2021 and will take effect August 29, 2021.  Based on the type of mail you send, the increase could be higher or lower. Also, when you look at the new rate charts provided by the USPS®, they typically will not show the level of detail needed (Previous and new rates, side by side) to see these differences.

Hopefully, this will help you budget by seeing the impact of the most common services that you use today.  At the bottom of this article there is also a link to an excel tool where you can plug in your mail volumes to see the impact to your organization.

Here is a link to a simple chart of all the rates below.

First-Class Mail® Single Piece – 3.2% – 16% Increase

The price of a stamp will go up by $.03 and the same for the additional ounce rates.  Metered Letters are seeing a $.02 increase to $.53 and will have the same additional ounce increase. A single piece flat is increasing from $1.00 – $1.16.

First-Class Mail® Commercial – 7% – 20.7% Increase

Automation letters are going up 7-8% and Flats are seeing 15-21% increases.

The biggest change in this category occurred a few years ago when they increased the weight limit for the Commercial Letter rates to 3.5 ounces.  The goal was to increase the value of the mail piece allowing customers to add additional content at the same price.

When you look at the chart above and compare the rates of a 3-ounce Metered Letter at $0.98 to a Commercial rate at $0.426 it is a 57% savings!  This is a big win for presort services that are now more valuable because of the savings they can provide.  Also, for flats, (9 x 12 or 10 x 13) consider folding those into 6 x 9 envelopes.  The savings can be significant with these new rates and weight savings.  A 3oz. flat at $1.56 now could cost as little as $0.426 at the letter rate, assuming it could be automated through in-house software or presort services.

Marketing Mail® (Formerly called Standard Mail) – 5.8% to 11.9% Increase

Marketing Mail® Letter rates are increasing at approximately 6.9-8.6% while Flats are going up at 7.1-10%.  The destination entry level Letter discounts are increasing up to 5-12.5% where with Flats are holding at the DNDC level but increasing 1.3-2.3% as you can see from the table below.

Additional Rate Change Items


This is the largest increase we have seen in years and mailers are going to need to look for savings strategies to help offset these changes.

To budget for this increase, you need to look at the type of items you are sending, and the weight and zones that are most common, to truly estimate the impact.  We have developed a Microsoft Excel-based budget calculator that you can download for free that should help you better plan for this year. Some of the most popular USPS classes are going up at the highest rates but luckily there are ways to help mitigate this through automation and technology.
