Starting Bids and Increments Explained For Nonprofit Auctions
You have secured the items. The online catalog is built or the bid sheets are printed. Now comes the question that stalls a lot of auction planning: what number do you actually put in the starting bid field?
Set it too high and the item sits untouched all night. Set it too low and you leave money on the table, especially if your nonprofit paid for the item in the first place. The good news is that pricing silent auction items is not guesswork. There are proven rules of thumb, and once you understand the three numbers behind every item, you can price an entire catalog quickly and confidently.
This guide covers the three numbers you need for every item, the percentages that actually work, and how to adjust them by item type.
What Is Fair Market Value in a Silent Auction?
Every pricing decision begins with fair market value, or FMV. This is the retail price a bidder would reasonably expect to pay for the item somewhere else. For a $200 restaurant gift card, the FMV is $200. For a donated week at a lake house, you determine the FMV in conversation with the donor based on comparable rental rates.
FMV matters for two reasons. First, it is the foundation for your starting bid and increment math. Second, it is the figure your winning bidders may need for their own tax records, since the amount a bidder can treat as a charitable contribution is generally only the portion they pay above fair market value. Getting FMV right protects both your revenue and your donors.
One caution: do not inflate FMV to make an item look more impressive. An inflated value creates a starting bid that is too steep, and it can mislead bidders about what they are able to deduct.
The 3 Numbers to Set for Every Auction Item
Every silent auction item needs three pricing decisions:
Starting bid. The opening bid that gets the item into play. This is the single most important number for driving participation.
Bid increment. The minimum amount each new bid must raise the current bid. This controls how quickly the price climbs.
Buy It Now price (optional). A fixed price that lets an eager bidder skip the bidding and take the item immediately.
Get these three right and the item does most of the work itself.
What Percentage of Retail Should a Silent Auction Starting Bid Be?
The widely used rule of thumb is to set the starting bid at roughly 30 to 50 percent of fair market value.
The logic is behavioral. A low, fair entry point invites that crucial first bid. Once someone has bid, they tend to feel invested and are far more likely to bid again to defend the item. A starting bid set too high removes that first easy step, and the item stalls before any momentum builds.
Where you land inside the 30 to 50 percent range depends on the item:
Common, easy-to-value items like gift cards and electronics can open higher, around 40 to 50 percent, because bidders know exactly what they are getting and a higher opening still feels fair.
Unique or high-demand items where excitement runs hot can also support the higher end, since you want to capitalize on the competition.
Niche items and experiences with a less obvious value, like a travel package, benefit from a lower entry point around 30 percent to attract that first bid.
If your nonprofit purchased an item rather than receiving it as a donation, make sure the starting bid at minimum covers your cost, or use a reserve price if your platform supports one so the item cannot sell below what you paid.
How to Set Silent Auction Bid Increments
Once the item is in play, the bid increment keeps the price climbing. The common guideline is to set the increment at about 10 percent of fair market value, then round to a clean number like $5, $10, or $25 to keep bidding simple.
Increments deserve more attention than they usually get, because they have a real effect on your final total. Set them too high and you discourage the smaller step-up bids that build momentum. Set them too low and the price crawls upward all night without ever reaching the item’s real value.
A few adjustments help:
For higher-value items, you can hold increments near 10 percent of FMV or a touch higher to keep the climb meaningful without scaring off bidders.
If you are using mobile bidding, you can often run slightly smaller increments than you would on paper. Tapping a phone to raise a bid is effortless, so bidders make those frequent small increases more readily than they would by crossing out a line on a sheet.
You can also adjust increments once bidding is underway. If an item is drawing heavy interest, a larger increment captures more of that enthusiasm.
How to Set a Buy It Now Price
A Buy It Now price gives eager bidders the option to purchase an item outright rather than wait out the bidding. A common approach is to set it above fair market value, often in the range of 150 to 200 percent of FMV, so that an instant sale still clears a healthy margin for your cause.
Buy It Now works best for items with a clear retail value and for items you have in multiple quantities, like gift cards or bottles of wine, where an immediate sale is a win and does not remove your one showpiece item from the floor.
Silent Auction Pricing Chart by Item Type
Use this chart as a starting framework, then adjust based on your own audience and past results:
| Item type | Starting bid (% of FMV) | Bid increment (% of FMV) |
|---|---|---|
| Gift cards and retail items | 40 to 50% | 5 to 10% |
| Electronics and technology | 40 to 50% | 5 to 10% |
| Experiences (dining, spa, local activities) | 40 to 50% | 5 to 8% |
| Travel packages | 30 to 40% | 5 to 8% |
| Unique or high-demand items | 40 to 50% | 10% |
Worked example: a donated dinner-for-two package with a $150 fair market value might open at $60 to $75 (about 40 to 50 percent), climb in $10 to $15 increments (about 10 percent), and carry a Buy It Now price around $250 to $300 for a guest who does not want to wait.
Setting Auction Prices in AuctionSnap
Once you have your framework, the software is where you put it to work. In AuctionSnap, you set the starting bid and bid increment for each item as you build your catalog, and you can add a Buy It Now price on any item where it makes sense, so the pricing rules you have decided on are in place before a single bid comes in.
One feature worth knowing: you can lower a starting bid during the event. If an item is not drawing interest on auction night, you are not locked into the number you set, and a quick adjustment can get it moving.
Priced well, every item does its own quiet work: inviting that first bid, building momentum, and climbing toward its real value while your team focuses on the guests in the room.
Pricing is just one piece of a smoother auction. For a look at how the right software cuts down the manual work before and after your event, see how to leverage nonprofit software to streamline auctions.
