What is Indirect Project Costs?

Indirect project costs refer to expenditures generated during or in connection with the execution of a project that cannot be easily and directly assigned to a particular activity, output, or line item. In grant practice, these costs are frequently calculated as a flat rate derived from the project's direct costs.

Unlike direct costs, indirect expenses usually do not require verification through individual invoices or accounting records. Their amount is calculated according to the specific call regulations—for instance, as a set percentage of eligible direct expenditures.

Difference Between Direct and Indirect Costs

Direct costs represent expenses clearly traceable to a specific project task or item. Examples include purchasing machinery, construction work, salaries of team members directly working on the project, specialized professional services, or software procurement.

By contrast, indirect costs cover general expenses that support the project but are harder to assign to one specific output. They may encompass administrative duties (such as accounting), office supplies, utilities, rent, internal operational support, or general project management, provided the specific call guidelines permit it.

Bonuses Paid from Indirect Project Costs

This term refers to performance bonuses or remuneration funded through the indirect costs portion of the budget. They typically apply to administrative, project management, or support staff, provided this is allowed by the rules of the given grant call.

Flat Rates for Indirect Costs

In many grant programs, indirect costs are established using a flat rate. This means they are not reported based on actual receipts or paid invoices, but are instead determined as a percentage of the total direct costs of the project.

Preventing double funding is crucial in this context. An expense covered by a flat rate for indirect costs generally cannot be claimed simultaneously as a direct eligible cost. This principle is explicitly outlined in standard methodologies governing flat-rate financing across European funding frameworks.
