How does the Additional Cost Model (AC) work?
In the additional cost model, only eligible direct costs that are additional to the recurring costs and eligible indirect costs may be charged to the grant agreement. This model is only available to non-commercial or non-profit organisations established under private or public law and international organisations which do not have an accounting system that allows the share of their direct and indirect costs relating to the project to be distinguished. More information on the cost models can be found in annex 5 of the guide for propsers and in the model grant agreements.
