Kickstarter keeps 5% and there's a 3-5% processing fee...but kick starter doesn't allow personal funding, its creative only and your project has to be approved. Indiegogo or GoFundMe would be better options.Here's a list of costs/fees for some of the more popular crowd funding sitesKickstarter keeps a good chunk, and the taxes on it suck, from what I've heard. Research it fully. If it is just operating cash influx a return could come around fairly quickly, right? You may be able to raise that in here.
