A little cold water for crowdfunders: Most Kickstarter campaigns have failed.
As of today, some stats from Kickstarter. Since inception, Kickstarter has raised over $920 million. Fees to Kickstarter have totaled approximately $46 million (5%), with payment processing fees of about $37 million (average of 4%, fees run between 3-5%), mostly to Amazon Payments.
Kickstarter is an all or none funding platform, as compared to Indiegogo that permits a closing at less than the target amount. Accordingly, 56% of all Kickstarter campaigns failed, with the highest failure rate being Film/Video. 10% of projects never received a single pledge, while 80% of projects that raised more than 20% of their goal were successfully funded.
On the bright side, the most successful category has been Dance with a 71% success rate, followed by Theater 64%, Music 55%, Comics 49% and Art 48%. Categories raising over $1M were Games 29 (campaigns), Technology 11, Design 7, Film/Video 3.
