For prices, see Notice 123–Price List.

1.3 Computing Postage
1.3.1 Determining Single-Piece Weight

To determine single-piece weight in a mailing of nonidentical-weight pieces, weigh each piece individually. To determine single-piece weight in a mailing of identical-weight pieces, weigh a group of at least 10 randomly selected pieces and divide the total weight by the number of pieces in the sample. Express all single-piece weights in decimal pounds rounded off to two decimal places.

1.3.2 Computing Postage for Affixed Postage

For each piece, affix the postage for the weight increment. To calculate the total postage for the mailing, add all of the affixed postage amounts for each piece.

1.3.3 Computing Postage for Permit Imprint

To compute the total postage for a mailing, for each weight increment, multiply the number of pieces by the applicable price per piece. Round each product off to four decimal places; add the products and round up the total postage to the nearest whole cent.
