A practical way to settle guest count cost calculator using the quotes and dates you already have, rather than a figure copied from somewhere else.
Start here
Work guest count cost calculator out from your own numbers. Write down what you have been quoted, mark anything you have not been quoted as unknown, and use the calculator on this page instead of an average you cannot check.
What this calculator works out
A practical way to settle guest count cost calculator using the quotes and dates you already have, rather than a figure copied from somewhere else.
It answers
- What have you actually been quoted in writing, and what is still an estimate?
- Which costs move with the guest count and which stay the same?
- Which line items are included, which are excluded, and which are still unknown?
- What date does someone else need an answer by?
- What changes if the number you are planning around turns out to be wrong?
A worked example you can copy
What cutting the guest list is actually worth
- Variable spend at 120 guests: $9,960.00.
- Variable spend at 100 guests: $8,300.00.
- Difference: $1,660.00 for 20 fewer guests.
- Per guest removed: $83.00, not the $83.00 headline per-guest rate.
- The food-and-beverage minimum is reached at 94 guests; below that the catering line stops falling.
| Line | Amount |
|---|---|
| Variable spend at 120 guests | $9,960.00 |
| Variable spend at 100 guests | $8,300.00 |
| Saving | $1,660.00 |
| Saving per guest removed | $83.00 |
| Headline per-guest rate | $83.00 |
| Shortfall against the minimum | $0.00 |
Where this usually goes wrong
Each of these is cheap to avoid now and expensive to fix later. They are the mistakes that surface in the final invoice.
Watch for
- Treating an unknown fee as if it were zero, which makes the cheaper-looking option win on paper.
- Comparing two quotes at different guest counts.
- Planning around a figure from an article instead of the quote in your inbox.
Your next conversation, in checklist form
Your next conversation, in checklist form
- Ask for the quote in writing, itemised, at one guest count.
- Mark every line without a price as unknown rather than zero.
- Ask which lines each percentage fee is calculated on.
- Write down the date the quote expires.
- Note what changes if the guest count drops by ten.
- Re-run the calculator once the missing numbers arrive.
Questions couples ask
Do I need every number before I can start?
No. Start with what you have, mark the rest unknown, and the calculator will show you how much of the total is still open.
Why is there no national average on this page?
Because an average cannot be sourced to your city, your date or your guest count. A number you build from your own quotes is the one you can act on.
Your next decision
Once this is settled, the pages below are the next decisions in the same cluster.
Assumptions this calculator makes
- Per-guest costs are the ones you were quoted, entered per person.
- Food and beverage is separate from other per-guest costs.
- The minimum spend applies to food and beverage only.
- Fixed costs are optional here; they do not change with the guest count.
What it does not do
- Some contracts renegotiate the minimum if the guest count drops. This calculator assumes the minimum you entered still holds.
- Staffing and rental counts sometimes step down in blocks rather than per person. Enter those as their own scenario.
- Savings shown are arithmetic, not an offer from a vendor.
