Making it clear what people get back from their investment is an integral part of the plan for any organisation seeking investment, whether it is through more traditional types of investment or crowdfunding.

However, for reward-based crowdfunding campaigns in particular, structuring the different tiers and offering better rewards as you move from low to high level tiers is a key feature of maximising the overall contributions you can get from funders.

For example in the lowest tier of the campaign for computer game Starforge $15 gets you one copy of the computer game, whereas the medium $100 tier gets you three copies of the game plus a range of game merchandise.

Also, it's important to ensure that the tiers and rewards are set at the right level and correspond with what funders want and are willing to pay for. From Kickstarter we know that the average pledge is $70, but the common pledge is $25.
