I have co-chaired two auctions. One auction that has a $150000 goal and with this auction, we go on the premise that less is more. We have seven live package items and nine silent items and that is it. We receive a lot of inkind donations, even one cash donation at $50000 and two at $10000 so off the bat, we have $70000. Tickets are also $175.00 a piece to this auction and there is minimal overhead as everything is donated. Best practice for auctions is to have less items out because clutter overwhelms people.
For the current auction I am doing with a $45000, we have to have a lot more items to auction off. Our ticket prices are only 35.00 but luckily most everything including food has been donated. We will be bundling items more and having a buy it now option on key items that is higher than we would anticipate getting via bids. Last year we had too many items and had leftover items that we took to the school website and let those who did not attend buy, first come, first serve.
Here is a formula I have learned from auction trainings. Not sure if this is what you need or if I am on a tangent. Good luck.
How much do you need to raise through auction? Estimate packages will sell at about 60% FMV for Live and 50% for silent. You may do better than that, but that's a conservative estimate. (If you know how things sold last year in relationship to FMV, you can adjust to those percentages.) So if you need to raise 10k through live and silent, you need to procure about $20K in fair market value. If you want lower priced, more accessible packages (so everyone can bid) you'll have to get more packages in order to get to the revenue number you need.
Live - A rule of thumb is about 8-12 packages. Plan on 3 minutes per item.
Silent - Plan based on number of buying units (wallets) in the room, not the number of guests - couples count as one buying unit. Make sure you have enough packages that there is some variety, but few enough to generate competition. Keep in mind on average it takes four bids to reach 50% of FMV. Package smaller items together so you have fewer overall packages with higher FMVs.
Just my two cents and I love hearing from others! Good luck
