Invitation Quantity and Postage Calculator

One invitation goes to each household, so households = guests ÷ the average guests per invitation, rounded up. The order adds a spare share for mistakes, late additions, and keepsakes, and 10% is common. Printing cost = invitations ordered × the price per set. Outgoing postage covers one envelope per household, and return postage covers a prepaid RSVP envelope for each household in the worst case where every reply comes back by mail. Odd sizes, square envelopes, and heavy inserts can raise the postage, so have a finished sample weighed at the post office before you buy stamps. Example: with Guests on the list 150, Average guests per invitation 2, Spare invitations 10 %, Price per invitation set 3.2 $, Postage per outgoing envelope 0.78 $, and Return postage per RSVP envelope 0.78 $, the result is Invitations to order = 83; Households to mail = 75; Printing cost = $265.6.
