There are two different funding methods for Crowdfunder projects.
1. All or Nothing – You will only receive your pledges if you hit your target. This is best suited for projects that need to reach a set target to be able to carry out their aims. The average pledge size on 'All or nothing' projects is £50.
2. Keep what you raise (flexible funding) – Keep all of your pledges, whether your project hits target or not. This is best suited for causes or charitable projects. The average pledge size on 'Keep what you raise' projects is £10.
'All or nothing' projects generally raise more money, but you do have to hit your target. 'Keep what you raise' means that you’ll keep all the money pledged by your supporters, but you’ll also have to fulfil all of the rewards people have pledged on, no matter how much or little is pledged in total.
