How does the wedding budget calculator work?
A wedding budget calculator turns your total budget into a dollar amount for each part of the day, using standard wedding budget percentages that you can edit. Add your guest count and it also shows your cost per guest, the single most useful number for keeping a wedding on budget.
Most of your spend rides on the guest count, because catering, rentals and drinks are all per-person. Watch the cost-per-guest figure move as you change the numbers — trimming the list is usually the biggest lever you have.
Tick include a wedding planner and a planner slice is added and the other categories rebalance around it. You can also type your own percentage for any category (the rest rebalance to 100%), and enter a catering price per head to check that guests × per-head fits your venue and catering slice.
How much does a wedding cost per guest?
As a rough guide, all-in costs often land around $200–$400 per guest, because catering, rentals and drinks are charged per person. For context, US weddings in 2024 cost about $33,000 on average, according to The Knot 2025 Real Weddings Study. Weddings with under 50 guests averaged about $15,000, and those with over 100 guests about $42,000.
Averages hide a huge range — region, season and style move the number as much as guest count. Rather than chasing an average, set a total you're genuinely comfortable spending and work backwards; the calculator shows your cost per guest as you change the numbers.
How should I split my wedding budget?
Venue, catering and rentals take the biggest share (about 44%), then photography and video (about 13%). Applied to your total, a common split looks like this (without a separate planner):
| Category | Share of budget |
|---|---|
| Venue, catering & rentals | ~44% |
| Photography & video | ~13% |
| Flowers & décor | ~9% |
| Music & entertainment | ~9% |
| Attire & beauty | ~8% |
| Rings | ~3% |
| Stationery & seating | ~3% |
| Cake, transport, favors & buffer | ~10% |
- Venue, catering and rentals are usually ~44% of the whole budget.
- Photography and video together are often the next biggest slice.
- Seating charts and place cards fall under stationery — a small line.
- Always keep a buffer for the surprises that come up.
Your seating chart and place cards sit in the stationery slice — small in the budget, but the part guests actually touch on the day. Build your seating chart free with our seating chart maker, starting from one of the free wedding seating templates such as the seating chart template; print-ready charts and place cards are part of Pro ($39 one-time).
Where to save (and where not to)
- Trim the guest list — the single biggest saving, since so much cost is per head.
- Pick an off-peak date — a Friday, Sunday or winter date can cut venue and vendor prices sharply.
- Choose an all-in venue — bundling catering, tables and chairs often beats hiring each separately.
- Don't skimp on photography — it's what you keep, and it's hard to redo.
Building the guest list is where the budget really takes shape — see our guide to making a wedding guest list.

Guests are the biggest driver of cost, mostly through catering and rentals. A rough figure is $200–$400 per guest all-in, but it depends heavily on your venue and menu. The calculator shows your exact cost per guest as you change the numbers — a fast way to see how the guest list moves the budget.

The calculator applies these to your budget, and you can edit any percentage.
How does a wedding budget calculator work?+
You enter your total budget and guest count; it splits the total across the usual categories (about 44% venue, catering and rentals, 13% photography and video, and smaller shares for the rest) and divides it by your guests to give a cost per guest. You can change any percentage and the others rebalance to 100%.
Are these percentages exact?+
No — they're a sensible starting framework. Your priorities (say, splurging on photography) and your region will shift the mix. Use the breakdown as a plan to adjust, not a rule.
