Calculating Your Postage

If you measure your mailpiece or package and have an idea of how much it weighs, you can calculate the postage yourself.


Save  Save  Save  Save

Just a few small changes can result in postage savings

  • Folding a sheet of paper in half will change the mailpiece from a "flat" sized piece to a "letter" sized piece and save you at least 44 cents.
  • If your letter is over 1/4" thick trifolded, unfold to the size of 1/2 sheet of paper and mail in a larger envelope up to 6-1/8" X 11-1/2" in size.  This will save you at least 44 cents.
  • Attaching a paper clip or a binder clip to several pieces of paper can change your mail piece from a "flat" sized piece to a "package" piece.  This will add at least 83 cents to your postage cost.
