**Summary:** A grant can make a project possible, but it rarely covers everything. Companies usually pay part of the costs themselves, carry some costs the programme does not accept, spend staff time on management and reporting, and need cash to bridge the gap before payments arrive. This article explains what to budget for before applying, so that the real cost of an EU-funded project is clear from the start.

## 1. Funding is only one side of the equation

When companies look at EU funding, the headline number gets the attention: a grant of several hundred thousand or a few million euros. The more useful question is what the project will cost the company in total, and how much of that the grant actually covers.

A grant reimburses eligible costs at a certain rate. It does not pay for everything connected to the project, and it does not remove the work of delivering and reporting on it. A project that looks attractive on the funding side can look quite different once co-financing, ineligible costs, internal effort and timing are added in. Looking at both sides early is what makes the decision a sound one.

## 2. Understanding co-financing requirements

Most programmes require the company to contribute part of the eligible costs. In Horizon Europe, for example, innovation projects are typically funded at up to 70% of eligible costs for companies, and research projects at up to 100%. A project with a 70% rate and €1 million in eligible costs would bring in up to €700,000, leaving €300,000 for the company to fund.

The own contribution must come from the company's own resources or other permitted sources, and rules differ by programme. Some programmes also reimburse indirect costs through a flat rate (in Horizon Europe, 25% of eligible direct costs, with some items excluded from the base). If your actual overheads are higher than the flat rate, you carry the difference.

## 3. Eligible vs. ineligible costs

Not every expense that belongs to a project can be charged to the grant. Eligible costs are defined by the programme and usually include personnel working on the project, equipment (often only the share used for the project), subcontracting and certain other direct costs, within the project period. They must be actually incurred, recorded properly and necessary for the project.

Typical sources of ineligible or limited costs include expenses incurred before the project start date or grant signature, costs that are not documented, items already funded by another source (double funding is not allowed), and costs the programme excludes or caps. Subcontracting may be limited, and some programmes require competitive quotes. Read the call and the grant agreement rules before building the budget, and treat anything unclear as a risk to be clarified.

## 4. The internal resources your project may require

A funded project is a managed project. Beyond the technical work, someone has to coordinate partners, track time and costs, keep supporting documents, prepare periodic reports and respond to questions from the funding body. Applications themselves also take effort: strong proposals are usually prepared over weeks, not days, and may involve finding partners in other countries.

For a small company, this can mean a meaningful share of one or more people's time. Not all of it is reimbursable. Personnel costs for project work usually are, but time spent on proposal writing before the grant starts, or on general management beyond the covered overheads, often is not. Decide in advance who will lead the project, who will handle finance and reporting, and whether outside support is needed.

## 5. Cash flow and payment timing

Grants are usually paid in stages, not all at once. In Horizon Europe, the coordinator typically receives a pre-financing payment shortly after the grant agreement takes effect, and further payments follow after periodic reports are approved. Part of the grant is held back until the end of the project, including a contribution to a mutual insurance mechanism and a final retention. Interim and final payments are also capped as a share of the maximum grant. The exact percentages and deadlines are set in each grant agreement.

The practical consequence is that the company often has to pre-finance costs. You may pay salaries, equipment and subcontractors for months before the related reimbursement arrives. In a consortium, money also passes through the coordinator to the partners, which adds time. Build a cash-flow forecast for the project, and check whether your own reserves, a bridge loan or other financing can cover the gaps.

## 6. What happens if project costs change?

Projects rarely run exactly as budgeted. Prices rise, a partner changes, a task takes longer, or a technical approach shifts. What matters is how much flexibility the programme allows. Some budget shifts between cost categories are permitted within limits, while larger changes may require a formal amendment to the grant agreement. Spending that departs from the agreed plan without approval may be rejected at reporting stage.

Costs that exceed the budget are generally not reimbursed, so overruns fall on the company. Reports and cost claims can also be audited, sometimes after the project ends, and unsupported costs may have to be repaid. Understand the rules on budget changes, reporting deadlines and record-keeping before you sign, and keep documentation in order throughout.

## 7. How to assess whether EU funding makes financial sense

Before committing to an application, a short checklist helps:

- **Total project cost:** What is the full budget, including ineligible costs and internal effort?
- **Grant amount and rate:** How much could realistically be reimbursed, and what remains for the company?
- **Co-financing:** Can you fund your share from your own resources or other permitted sources?
- **Cash flow:** Can you cover costs until payments arrive, and what would a delay mean?
- **Internal capacity:** Who will manage the project, finance and reporting, and how much time will that take?
- **Application effort and odds:** What will preparing the proposal cost, and how competitive is the call?
- **Strategic value:** Does the project matter to the business even without funding, and what else does the grant bring, such as partners, credibility or visibility?
- **Obligations and risks:** What are the reporting duties, audit exposure and consequences of changes or delays?

If the numbers and the obligations still work after this check, the project is worth pursuing. If they do not, a different programme, a smaller scope or another financing route may be the better choice. Either outcome is better than finding out after the grant is signed.

Before committing to an EU-funded project, make sure you understand both the potential financial support and the responsibilities that come with it.
