Thank You Card Calculator — Post-Event Cards
Calculate how many thank you cards you need after your event.
How We Calculate This
This calculator estimates thank you card quantities based on your guests, gift givers, and households.
Formula
- Cards needed = households if known, otherwise the larger of gift-giving households or attending households (each ÷ guests per household)
- Total to order = cards needed + spares (typically 10–20% extra for write-mistakes and late gifts)
- Print cost = total cards × cost per card
- Postage = cards actually sent × postage per card (spares are not posted)
- Grand total = print cost + postage + envelopes
Etiquette is one card per household or couple — not one per head. A couple or family who gave a single joint gift receives a single card. Order ~10–20% more than you estimate to cover handwriting mistakes, last-minute changes and surprise gifts.
