While a project is live you can adjust your pledge by visiting the project page and clicking the “Manage your pledge" button. On the following page, select "Change your pledge".
From here, you’ll be able to adjust your pledge amount or switch to a different reward tier (changing reward tier will automatically update your pledge amount). Additionally, you’ll have the option to add any add-on rewards, or give a little extra with bonus support.
If you’d prefer not to receive a reward, simply change to the "Make a pledge without a reward" tier and enter your new pledge amount.
Remember, when changing your pledge amount you are not adding to your existing pledge, the new amount you enter will be the total amount collected if the project is successfully funded.
Once a project has ended it is no longer possible to modify your pledge amount or reward selection. If you need to seek out an alternative arrangement, we recommend reaching out to the project creator.
If you experience any issues while trying to complete your pledge, please consult this article of common pledge problems.
