We encourage creators to research all costs involved in completing their project prior to launching. Your funding goal should be the minimum amount of funds you need to complete your project and make and ship any rewards. Once your project has launched, the funding goal and deadline cannot be changed.
It helps to make a list of all the materials, resources, and expenses you'll need to complete your project, and the estimated costs for each. Research how much things will cost, and consider how your expenses could change if you had to switch suppliers or fulfillment partners (it never hurts to have a back-up plan). We’ve also compiled a list of services that can aid in the process of completing your project.
Keep in mind that any funds pledged towards shipping costs will also count towards your goal.
Additionally, a Kickstarter fee and payment processing fees are collected from the funding total for successfully funded projects. The complete fee breakdowns are available here.
