What happens if I'm unable to raise the entire amount?
PPL decided to follow the "all or nothing" model, which means that, in that case, all contributions will be refunded to the original backers. There are no costs for any party, besides the time and effort devoted to the project.
Should the project owner receive a partial amount, he will most likely fail to implement the project and deliver the rewards to the investors. No one would win!
Thus, it is important to set a reasonable target for your project. It should be the minimum amount that allows you to go forward with the project. If you are very successful in your fund raising, it’s possible you can receive much more than the initial value.
