Lump Sum Grant

A lump sum grant is a simplified funding model under Horizon Europe and other EU programmes where beneficiaries receive a fixed amount upon completion of each work package, rather than being reimbursed for actual costs incurred. Authorized by Article 181 of the EU Financial Regulation (Regulation 2018/1046), lump sum funding eliminates the need for timesheets, detailed cost reporting, and financial audits, dramatically reducing the administrative burden for both participants and the European Commission while maintaining a focus on delivering project results.

How It Works

In a traditional (actual-cost) EU grant, beneficiaries track every euro spent on the project, submit financial statements with supporting documentation, and undergo financial audits for grants above EUR 430,000. This process is administratively burdensome and accounts for a significant portion of the total effort involved in managing an EU-funded project.

Lump sum grants fundamentally change this model. Instead of reimbursing actual costs, the EU pays a pre-agreed fixed amount for each completed work package. The payment is binary: if the work package is completed as described in the grant agreement, the full amount is paid; if it is not completed (or is only partially completed), payment is reduced or withheld.

The lump sum grant lifecycle works as follows:

Proposal stage. Applicants prepare their proposal following the standard Horizon Europe template but with additional budget detail. For each work package, applicants define the activities, deliverables, milestones, and a fixed cost. The total of all work package costs constitutes the project's total lump sum. The budget must be realistic, reasonable, and consistent with the proposed activities. Evaluators assess the budget for appropriateness during the review process.
Evaluation. The standard three evaluation criteria (Excellence, Impact, Implementation Quality) apply. Under Implementation, evaluators specifically assess whether the proposed work package costs are reasonable and consistent with the work described. Proposals with costs that are clearly inflated or insufficient for the proposed activities will score poorly.
Grant agreement. The grant agreement specifies the fixed amount per work package for each partner. These amounts are legally binding and cannot be changed during the project except through a formal amendment. The work package description in the grant agreement defines the "completion criteria" — what must be achieved for payment.
Implementation. During the project, beneficiaries implement the work plan as described. The critical difference from actual-cost grants is that no detailed financial tracking is required. There are no timesheets, no invoices to allocate, no cost category reports, and no distinction between direct and indirect costs. Beneficiaries have full flexibility to spend resources as needed within each work package, provided the scientific and technical outputs are delivered.
Reporting and payment. At each reporting period, beneficiaries report on the technical progress and completion status of work packages. For each work package declared as completed, the agreed fixed amount is paid. The European Commission assesses whether the work package deliverables and milestones have been achieved based on the technical report. If a work package is not completed, the corresponding payment is withheld.
No financial audit. Because there are no actual costs to verify, financial audits (Certificates on Financial Statements, or CFS) are not applicable to lump sum grants. This eliminates one of the most time-consuming and contentious aspects of EU grant management.

The European Commission estimates that lump sum grants reduce administrative effort by approximately 70% compared to actual-cost grants. This reduction benefits all parties: beneficiaries spend less time on financial management and more time on research; project officers spend less time reviewing cost claims; and auditors focus on technical delivery rather than financial compliance.

Legal Framework

Article 181 of the EU Financial Regulation (Regulation 2018/1046) provides the legal basis for simplified cost options in EU grants, including lump sums, unit costs, and flat rates. The article authorizes the use of lump sums "where the nature of the supported activities or the linked outputs can allow it."

Article 180 of the Financial Regulation establishes the principle that grant amounts shall be determined on the basis of either actual costs, simplified cost options, or a combination thereof. Lump sum grants fall under simplified cost options.

The Horizon Europe Regulation (EU) 2021/695, Article 37 encourages the use of lump sum funding and mandates the European Commission to increase its use throughout the programme's lifetime. The regulation was explicitly designed to expand lump sum funding beyond the pilot phase initiated under Horizon 2020.

The Horizon Europe Model Grant Agreement (HE MGA), Article 5.3 contains the specific provisions for lump sum grants, defining:

How work package completion is assessed
Payment triggers (binary: completed/not completed)
Partial completion rules (proportional reduction)
Transfer rules between work packages (limited)
Amendment procedures for changing lump sum amounts

Lump sum proposals receive additional page allowance. To account for the more detailed budget description required, lump sum proposals receive 5 extra pages in the Part B template: 45 pages for RIA/IA proposals (vs. 40 for actual-cost) and 28 pages for CSA proposals (vs. 25).

The European Commission has progressively expanded lump sum funding across Horizon Europe. In the 2021-2022 work programme, lump sums were used for selected topics as a pilot. From 2024 onward, the majority of Pillar II cluster topics use lump sum funding by default, with actual-cost options remaining for specific instruments (ERC, MSCA, large-scale research infrastructures) where the nature of the activity makes lump sums impractical.

Practical Examples

Example 1: Climate Research RIA. A consortium of 10 partners submits a RIA proposal to a Cluster 5 lump sum topic. The proposal defines seven work packages with the following fixed costs: WP1 (Management, EUR 280,000), WP2-5 (Technical WPs, EUR 3,200,000 total), WP6 (Dissemination, EUR 350,000), WP7 (Ethics, EUR 70,000). Total project lump sum: EUR 3,900,000. At each 18-month reporting period, the consortium reports on work package completion. WP1 and WP2 are completed in the first period; WP3-5 in the second period; WP6-7 in the final period. Payments are made per completed work package. No timesheets, no cost statements, no audit certificates.

Example 2: Partial Completion. In the project above, WP4 (pilot testing in three countries) is only partially completed by the end of the reporting period — testing was completed in two countries but delayed in the third due to regulatory approvals. The Commission accepts the work package as partially completed at 67% and pays EUR 360,000 of the EUR 540,000 work package budget. The remaining testing is completed in the next period.

Example 3: Budget Flexibility in Practice. A partner in a lump sum project initially budgeted EUR 80,000 for travel within their work package allocation. Due to pandemic-related travel restrictions, the partner shifts the budget to virtual collaboration tools and additional staff time. Under a lump sum grant, this reallocation requires no amendment or approval — as long as the work package deliverables are achieved, the partner receives the agreed fixed amount regardless of how resources were actually spent.

Key Considerations for Suppliers

Budget realistically from the start. Because lump sum amounts cannot be changed during the project (except through formal amendment), getting the budget right at the proposal stage is critical. Under-budgeting means you will spend more than you receive; over-budgeting will be caught by evaluators and may reduce your score. Use your organization's actual cost data to estimate realistic work package costs, including personnel, travel, equipment, and a reasonable contingency.

Define clear, measurable completion criteria. The payment trigger for each work package is completion of the described activities and delivery of the specified outputs. Vague work package descriptions create ambiguity about what constitutes "completion." Define specific deliverables (a prototype, a published dataset, a tested algorithm) and milestones (first pilot operational, user testing completed) that can be objectively assessed.

Take advantage of the administrative simplification. The primary benefit of lump sum grants is the elimination of financial reporting burden. This means no timesheets, no invoices to categorize, no financial audits, and no post-project cost claims. For organizations that find EU grant financial administration particularly burdensome (especially SMEs and newcomers), lump sum grants are significantly more accessible.

Understand the limited transfer flexibility. While you have full flexibility within a work package (you can spend on any eligible activity), transfers between work packages are restricted. If you realize mid-project that WP3 needs more resources than budgeted and WP4 needs less, you cannot simply shift the budget without a formal amendment. Plan your work package budget allocations carefully, with reasonable contingencies within each work package.

Consider the interaction with the funding rate. For IA projects where for-profit partners receive 70% funding, the lump sum represents 70% of the estimated costs. The 30% co-financing obligation still applies, but it is calculated on the estimated costs that formed the basis of the lump sum, not on actual expenditure. This provides certainty about the co-financing obligation from the outset.

Frequently Asked Questions

What happens if a work package is not completed?

If a work package is not completed by the project end, the corresponding lump sum payment is not made (or is recovered if an advance payment was issued). For partial completion, the Commission may apply a proportional reduction based on the degree of completion achieved. The assessment is based on the technical report: did the beneficiary deliver the agreed outputs and achieve the agreed milestones? If a work package is fundamentally not completed (less than 50% of the described work), the entire work package payment may be withheld. The grant agreement specifies the exact rules and thresholds for partial payment.

Can the lump sum amount be changed during the project?

In general, no. Lump sum amounts are fixed in the grant agreement and are intended to remain stable throughout the project. However, formal amendments are possible in specific circumstances: if there is a substantial change to the project scope that requires a new work package or a fundamental redesign of existing work packages, the consortium can request an amendment through the EU Funding & Tenders Portal. Routine cost variations (higher-than-expected travel costs, personnel changes) are absorbed within the existing work package budget and do not justify an amendment.

Are lump sum grants better or worse than actual-cost grants?

Neither is inherently better — they suit different situations. Lump sum grants are better for organizations that prioritize administrative simplicity, have reliable cost estimation capabilities, and prefer to focus on research delivery rather than financial compliance. They are also better for smaller organizations (SMEs, newcomers to EU funding) that may lack the administrative infrastructure for actual-cost reporting. Actual-cost grants may be preferable for very large projects where costs are difficult to predict in advance, for organizations with high actual overhead rates that benefit from claiming actual indirect costs (though this is no longer an option in Horizon Europe), or where the project scope may evolve significantly during implementation. In the 2024-2027 Horizon Europe work programmes, the default for most collaborative research topics is lump sum.
