How to Price Silent Auction Items: Starting Bids, Increments & Buy-It-Now

Every silent auction has a few items that close strong and a few that never get a single bid.
The ones that close strong aren't always the most expensive. They're the ones priced right.
Starting bids are one of the most high-leverage decisions in auction planning, and most event chairs set them by gut feel — or worse, by copying what they did last year. The result: items that open too high and kill early momentum, or items that start so low the final close doesn't come close to FMV.
There's a better way. It's not complicated. It's three numbers.
The Three Numbers Behind Silent Auction Starting Bids
Every item in your auction needs a starting bid, a bid increment, and a buy-it-now price. Set these correctly and you create the conditions for competitive bidding. Set them wrong and you're leaving money in the room.
Starting bid — the minimum first bid. Too high, no one opens the item. Too low, you close at a fraction of what donors would have happily paid. Industry standard: 30–50% of fair market value.
Bid increment — how much each new bid must beat the last. Too small and your auction turns into a tedious penny race. Too large and frustrated bidders walk away after the first raise. Standard range: 5–10% of FMV.
Buy-it-now price — an instant-win option at a premium. Set it at 200% of FMV and it does two jobs: it creates urgency for motivated donors, and it closes items cleanly before close-of-auction chaos hits.
What Happens When You Price Wrong: A Real Scenario
Say you have a $500 spa package. The donor confirms FMV is $500.
Overpriced scenario: You set the opening bid at $350 — 70% of FMV — because you don't want to "give it away." Nobody opens it. At close of auction, it's still blank. You scramble to raffle it off or carry it to next year's event.
Underpriced scenario: You set it at $50 — 10% of FMV — because you want "lots of energy." Two people bid. It closes at $100. Your room of 200 generous donors basically watched someone buy a $500 spa day for $100.
Right-priced scenario: You set it at $200 — 40% of FMV — with $25 increments (5% of FMV). Four or five bidders open it. Seven rounds of bidding later, it closes at $375. Not quite FMV, but you kept multiple bidders competing, generated real excitement around the item, and left the donor feeling great about the outcome.
The math matters. The percentages matter.
The Formula, By Item Type
Not every item should open at the same percentage. Understanding silent auction starting bids by item type is the key to maximizing revenue — high-demand, easy-to-value items like gift cards and electronics can open higher because bidders know exactly what they're getting. Niche items like travel packages need a lower entry point to attract a first bid.
Here's a quick reference:
Gift cards and retail items — Start at 50–60% of FMV with 5–10% increments. These are easy to value and donors know it. Higher opening bids still feel fair.
Experiences (spa, dining, local activities) — Start at 40–50% with 5–8% increments. Well-known and desirable, but slightly more personal so you want to invite broader participation.
Travel packages — Start at 30–40% with 5–8% increments. Date restrictions and personal logistics make these harder to commit to. Lower opening = more bidders willing to try.
Art and collectibles — Start at 30–50% with 5–8% increments depending on how recognizable the artist or piece is. Unknown artists need lower starting bids to generate any momentum.
Sports memorabilia — Start at 40–50% with 5–10% increments. Fan emotion drives these, but you need to attract the first bid before that emotion kicks in.
Technology and electronics — Start at 50–60% with 5–10% increments. High perceived value and easy to compare online, so bidders are comfortable committing at a higher opening price.
One Setting That Prices Your Entire Auction Automatically
If you're running your silent auction in HelloFund, you don't have to calculate any of this per item.
Go to Items → Manage Items → Pricing Defaults and enter your Starting Bid %, Bid Raise %, and Buy Now % once. From that point forward, every time you enter a Fair Market Value on any auction item, HelloFund automatically calculates and applies the starting bid, increment, and buy-it-now price — across your entire item list.
Add 50 items with their FMV values. Your auction is priced in seconds, not hours.
It only updates items with no active bids, so you can adjust mid-event without disrupting anything. And you can always override individual items manually when an item needs special handling.

Use the Calculator First
Before you set your pricing defaults, use our Silent Auction Bid Strategy Calculator to test how different percentages play out on real item values.
Plug in a $750 travel package. See what a 35% opening bid looks like versus 45%. See how 5% increments compare to 8%. See where your expected closing range lands.
Do this for a handful of representative items and you'll know exactly which percentages to plug into your HelloFund defaults before your catalog goes live.
A Few More Things Worth Knowing
Round your numbers. If 5% of a $400 item is $20, that's already clean. But if you land on an awkward number like $18 or $22, round to the nearest $5. Bidders process clean numbers faster and it keeps your mobile bidding experience tidy.
Display the FMV on every item. If an item's FMV is over $75, IRS quid pro quo rules require written disclosure. Including the FMV in your HelloFund item details keeps you compliant automatically — and it reassures bidders they're getting real value.
Don't skip the buy-it-now on gift cards. For predictable items, BIN at 200% closes fast and clean. A $100 restaurant gift card with a $200 BIN will often close before the auction even gets going.
Use text messages at close. HelloFund lets you schedule automated texts to bidders when the auction is closing. A well-timed nudge drives a real spike in last-minute bids on items that haven't hit their ceiling yet. Set it up in advance — it runs itself on event night.
The Bottom Line
Starting bids aren't guesswork. They're a formula — and the formula is simple once you know it. Thirty to fifty percent of FMV to open, five to ten percent increments to build, two hundred percent for an instant win.
Get those three numbers right and your auction runs itself.
