The method
Use one guest count for every quote. Add a room fee only when it is charged on top of food and drink. For a minimum spend, you pay the higher of the minimum and the food and drink you would actually order. A per-head price is that price times the guests, for the hours it covers. Divide the total by the guests when you want a per-head figure to compare. Ask whether GST is included. Do not assume it is.
The comparison guide is the same method written out, with a worked example that uses made-up round numbers and says so.
What Perth rooms publish
On 25 October 2026, Eventier’s catalogue had 2,374 rooms with an email within 80 km of Perth’s centre. 671 of those also publish a price on the venue’s own site. Reading those price texts: 158 mention room hire (including hire fee, venue hire or hall hire), 75 mention a minimum spend, and 115 mention a per-person price.
348 mentions sit in 292 texts, because one text can use more than one phrase. 379 of the 671 texts match none of the three phrases. The texts are messy (hourly community rates, prices in other currencies, and notes that there is no price), so these figures are phrase counts, not average dollars, and not a national figure.
A per-person phrase here means the text has a dollar amount beside words such as per person, per head, per guest, or pp. Room hire and minimum spend are those words themselves.
Work out a quote you have
Type your guest count and the figures from a quote. The calculator runs in the browser. It does not look up a venue, and it does not send what you type.
If the calculator does not run, do it by hand. Same guests for every quote. Pay the higher of the minimum and the menu you would order. Add room hire only when it is a separate fee. Divide by the guests for a cost per head.
