So,

in my experience when catering for a party there are a few questions you need to ask before working out how much meat to buy
In this case my engagement party will have 106 people.
Below is my variables and reasoning


How much meat? - (for main course)
you want to work out how much meat each person will have at your event. if its a sit down event then i would suggest that about 250-400g is about what you want
(think of a 400g Steak) and your customers will go home happy. however if you take into consideration the consumption of bread (burgers) and orderves then im going to go for 250.
demographic, lunch/dinner, event type ect all have effect on this.

how many people?
This is pretty simple but you do need to cater for (in some cases) children, people turning up with no rsvp and people leaving early.
usually you just run the RSVP number which caters for people extra when taking into account the lower consumption of children.

Yield of usable meat
This is the one that most people completely forget about
Pork shoulder, lamb shoulder, beef brisket all have 2 "losses" that you need to take into consideration
"trimming and evaporation"

-Evaporation is on average 30% of the yield lost
-trimming is variable depending on the cut.
In my case for a full packer brisket i loose about 15% trimming and another 30% of lost evaporation. I can make up some of this evaporation by foiling the cut and keeping the juices to re-add
For my calculations i will go with a 60% yield based on 40% loss
-Pork butts from costco have a 25%-35% loss and full pork shoulders (all fat on and bone in) can have as high as 50% loss


Here are my calculations


[How much meat?] x [how many people?] x 1.[yield loss i.e .4]
so for instance for 100 people at 250 grams and 35 % loss it would look like this

250 x 100 x 1.35 = 33750 grams or 33.75kg of meat for a 25kg yield which is required

I have created a nigty Spreadsheet here to do the calculations for you.
If you have any questions let me know

Very 'Big Bang' calculation, I think we'll have to change your user name to Sheldon :-)

That's a lot of meat, Beaver. When is the party? I've looked in Costco but hadn't seen full bone, full fat Pork Shoulders. I've just got back from South Melbourne market and got a 4.5kg full bone, full fat shoulder for $10.99/kg, looks really nice.

Did you get sorted with the smoker? The Yoder shipment won't be sorted till next week now, so no YS640 until well after Easter :-( So I've got Pork Shoulder, Chicken and Rib Eye for the long weekend but cooked on gas.

Good luck with the Engagement Party, your guests will enjoy their BBQ'd food :-)

yea, all good, i have calculated (sheldon) for every possible outcome.

as for the smoker, its likely ill be using (thanks to andy) the big offset

that think is going to look magnificent with about 45-48kg of meat in it all at once :)

for those interested, the reason i have done the above calculation is due to hosting a party of my own for 106 people.
i have done a party for 50 people before but this will be my biggest yet :)

it will be interesting but if i pull it off then there is not much difference between 100 and 200

Personally I love the challenge.
I'verun 250-300 person events in the past so love doing it.
Why? You offering?
I even got to organise a 900 person Christmas party (we did have a professional planner for that one though)

Heya Beaver, sorry for the huge thread dig, but was wanting to use the calculator but the link is 404'd. Any chance of a re up?
