Save the Date Calculator — Quantities & Timing
Work out save-the-date quantities and costs for your event.
How We Calculate This
This calculator estimates save-the-date quantities and costs based on your guest list.
Formula
- Cards needed = households if known, otherwise guests ÷ guests-per-household (default 2)
- Total to print = cards needed + spares
- Print cost = total cards × cost per card
- Postage = cards needed × postage per card (spares are not posted)
- Grand total = printing + postage + envelopes (posted sends only)
Frequently Asked Questions
Send save-the-dates 6-9 months before a wedding, 3-4 months before a milestone birthday, and 2-3 months before other formal events. For destination events, send 9-12 months ahead. They give guests time to book time off work and arrange travel.
Like invitations, send one save-the-date per household or couple, not per person. A couple living together gets one card. Family members at different addresses each get their own. This calculator estimates households if you only know total guest numbers.
Digital save-the-dates are increasingly popular and perfectly acceptable for most events. They are instant, free, and eco-friendly. For very formal events or older relatives, printed cards are still preferred. Some couples send digital to most guests and print a few for key recipients.
Include: names of hosts, date, location (city/venue), and a note that a formal invitation will follow. Do not include gift registry information. Keep it simple and on-brand with your event theme. A photo is popular for weddings.
