Stationery Total Cost Formula

Total Stationery Cost = (Total Printed * Suite Price) + (Total Printed * Save-The-Date Unit) + Outgoing Postage (Standard + Surcharges) + RSVP Return Postage
  • Invitation Suites: Main invitation card, details insert, and printed envelopes ($3.00-$8.00/suite).
  • Save-The-Dates: Postcards or cards with envelopes ($1.50-$3.00/unit).
  • Outgoing Postage: Current USPS 1oz Forever stamp rate plus 2oz or non-machinable square envelope surcharge.
  • RSVP Return Postage: Pre-stamped return envelopes or postcards.

Step-by-Step Worked Example

Scenario: A couple orders 80 invitation suites ($4.00 each) and 80 save-the-dates ($2.00 each) with 10 buffer copies, standard USPS postage ($0.73), and heavy weight surcharge ($0.44).

Calculation Steps:

  1. Invitation Printing: 90 * $4.00 = $360
  2. Save-the-Date Printing & Mailing: 90 * ($2.00 + $0.73) = $245.70
  3. Outgoing Invitation Postage: 80 * ($0.73 + $0.44) = $93.60
  4. RSVP Return Postage: 80 * $0.73 = $58.40
  5. Total Postage: $93.60 + $58.40 = $152
  6. Total Stationery Cost: $360 + $245.70 + $152 = $757.70
  7. Cost Per Mailed Suite: $757.70 / 80 = $9.47
Result: Total stationery and postage cost is $757.70 ($9.47 per mailed household).

How to Use This Calculator

  1. 1Enter the number of household addresses requiring an invitation.
  2. 2Include 10 to 15 extra buffer suites for keepsakes, photographer styling flat-lays, and address mistakes.
  3. 3Input printing rates and specify whether your invitation is heavier than 1 ounce or uses wax seals.

Assumptions & Limitations

  • Postage rates reflect standard domestic USPS first-class letter rates.
  • Wax seals, ribbon ties, and acrylic cards require the non-machinable surcharge.

Frequently Asked Questions

Why do wedding invitations often require extra postage?

Wedding invitations frequently exceed 1 ounce in weight due to heavy cardstock, RSVP cards, and detail inserts. Additionally, rigid wax seals, thick ribbons, or square envelopes cannot pass through automated USPS sorters, incurring a mandatory "non-machinable" surcharge.

When should save-the-dates and invitations be mailed?

Save-the-dates should be mailed 6 to 9 months prior to the wedding (9 to 12 months for destination weddings). Formal invitations should be mailed 8 to 10 weeks before the wedding, with an RSVP deadline 4 weeks before the big day.

Can online RSVPs save money?

Yes! Directing guests to RSVP via your wedding website eliminates the need to print physical RSVP response cards and buy pre-stamped return envelopes, saving $150 to $300.
