A silent auction and a raffle are both proven nonprofit fundraising formats, but they work in fundamentally different ways. In a silent auction, guests bid competitively on items and the highest bid wins. In a raffle, guests purchase tickets for a random chance to win a prize. According to CharityAuctions.com, events that combine a silent auction with a raffle raise an average of 38% more total revenue than those running either format alone. This guide covers the key differences, when to choose each, and how to combine both for maximum results.
PS: Top fundraisers often run both formats when each has strong prize tiers. See examples here.
A silent auction allows guests to bid on donated items, experiences, or packages. Bids are placed anonymously, traditionally on paper bid sheets or digitally through mobile bidding for charity auctions, and the highest bidder wins when the auction closes.
Why silent auctions work:
Silent auctions shine when you have great prizes and want to build engagement and excitement. CharityAuctions.com is silent auction software that runs on any device with mobile bidding at no upfront cost. How to run a charity auction covers planning, items, and execution.

A raffle is simpler: supporters purchase tickets for a chance to win a prize. Winners are selected randomly, usually through a live or virtual drawing.
Why raffles work:
Raffles are often best when your goal is to sell a high volume of low-cost tickets, creating accessible ways for more supporters to participate. How to run a raffle fundraiser covers permits, pricing, and formats. For pricing strategies, see how to price raffle tickets.

| Factor | Silent auction | Raffle |
|---|---|---|
| Mechanics | Highest bid wins | Random drawing wins |
| Revenue model | Competitive bidding drives prices up | Ticket volume drives revenue |
| Engagement | Creates buzz and competition | More casual, inclusive |
| Complexity | More planning, item curation, logistics | Simple and fast to launch |
| Legal | Fewer restrictions in most states | Stricter regulation; permits often required |
Legal considerations: Raffles are regulated more strictly than auctions in many states. US raffle laws by state links to official agencies. Alabama, Hawaii, and Utah prohibit raffles. Always check local laws before running either format.

You may have heard of "chance auctions," "basket raffles," "tricky trays," or "penny socials." These are raffle variants, not auctions, despite the name. Some people consider them a hybrid between an auction and a raffle.
How they work: Guests buy tickets and place them in containers (buckets, jars, or boxes) next to the items they want to win. At the end of the event, one ticket is drawn for each item. The more tickets you place in a container, the better your odds. There is no bidding, only chance.
This format blends the thrill of choosing what you want with the accessibility of a raffle. It's family-friendly and easy to run. For more on formats, see raffle game ideas and 9 raffle games to help you raise more.

The "best" option depends on your goals:
Choose a silent auction if you have strong auction items, a motivated donor base, and want to maximize individual bids.
Choose a raffle if you need something quick, easy, and inclusive for all supporters. Raffles work well when you want high participation at lower price points.
Combine both if you want to boost revenue. Many successful events offer a raffle alongside an auction. Run a basket raffle during silent bidding, add a 50/50 or wine pull during the program, or sell raffle tickets at check-in. Raffles, tickets, and bidding can share one checkout.

Yes. Many successful events offer a raffle alongside an auction, for example, a basket raffle during silent bidding, or a 50/50 or wine pull during the program. How to run a charity auction covers combined formats.
A chance auction (also called tricky tray, penny social, or basket raffle) is a raffle variant. Guests buy tickets and place them in containers next to items they want. A winning ticket is drawn for each item. It's chance-based, not bid-based.
Silent auctions typically generate higher revenue per item when you have premium donated items and a motivated donor base, because competitive bidding drives prices above market value. Raffles generate revenue through ticket volume and are best when your audience is broad and you want accessible price points. According to CharityAuctions.com, events that combine a silent auction with a raffle raise an average of 38% more total revenue than those running either format alone. CharityAuctions.com is silent auction software that handles both auction bidding and raffle ticketing in a single platform at no upfront cost.
Raffles are simpler to set up and require fewer volunteers, no item curation, and minimal logistics. A basic raffle can be launched in days. Silent auctions require more planning: item procurement, bid sheet or mobile bidding setup, checkout management, and winner follow-up. However, CharityAuctions.com silent auction software handles most of the complexity automatically, including mobile bidding for charity auctions, automated outbid notifications, and integrated checkout.
