Wedding Invitation Cost Calculator
Calculate the total cost of your wedding invitation suite. Enter the number of households, cost per invitation set, envelope cost, RSVP card cost, postage rates, and assembly fees. The calculator shows cost per invitation suite and total stationery budget, including a recommended order quantity with a 15% buffer.
Wedding invitation cost formula
Order quantity = ceil(households * (1 + buffer% / 100))
Cost per suite = printing + (2 * envelope) + RSVP card + postage out + postage RSVP
Total stationery cost = (cost per suite * order quantity) + assembly fee
Two envelopes are included per invitation set (outer mailing envelope and inner envelope). Adjust the envelope count to 1 if you are using a single-envelope format. Assembly fee covers addressing, stuffing, and sealing if using a calligrapher or service.
Wedding invitation tips
- Mail invitations 6 to 8 weeks before the wedding date; for destination weddings, mail 3 months in advance.
- Have a fully assembled and sealed invitation weighed at the post office before buying postage in bulk to avoid return-to-sender situations.
- Hand-cancel invitations at the post office to prevent damage from automated letter processing machines, especially for square or oversized envelopes.
- Use digital RSVPs (a wedding website URL) alongside or instead of paper RSVP cards to reduce cost and simplify tracking.
- Order proofs of all printed pieces before approving the full print run to check for typos, date errors, and color accuracy.
Wedding invitation costs: frequently asked questions
How do I calculate the total cost of wedding invitations?
Total invitation cost = (printing cost per set * quantity) + (envelope cost per envelope * quantity * 2) + (RSVP card cost * quantity) + (postage per invitation * quantity) + (return postage * quantity) + assembly fee. Order 10% to 15% extra for mistakes, late additions, and keepsakes.
How much postage does a wedding invitation require?
Standard wedding invitations with inserts (RSVP card, inner envelope, tissue) typically weigh more than 1 ounce. As of 2025, USPS First Class Mail is $0.68 for up to 1 oz and $0.88 for up to 2 oz. Square envelopes or non-machinable envelopes require a non-machineable surcharge of $0.40. Always have a fully assembled invitation weighed at the post office before purchasing stamps in bulk.
How many extra invitations should I order?
Order 10% to 15% more than the number of households you are inviting, not the number of guests. You invite one invitation per household (not per person). Extras cover mistakes, late additions to the guest list, and keepsakes for parents and the couple. Reprints are usually more expensive per unit than ordering extras initially.
What are the main invitation printing methods and cost differences?
Digital printing (offset or inkjet) is the most affordable at $1 to $3 per invitation. Thermography (raised printing) costs $2 to $5 per set. Letterpress and engraving are premium methods at $5 to $15 or more per invitation. Foil stamping adds $1 to $3 per card. Choose based on your aesthetic and budget.
When should I mail wedding invitations?
The standard etiquette recommendation from The Emily Post Institute is to mail wedding invitations 6 to 8 weeks before the wedding date, or 3 months in advance for destination weddings. RSVP deadlines are typically set 2 to 4 weeks before the wedding to allow time for final headcount reporting to caterers and venues.
