Treating pre-financing as your money

Pre-financing is an advance. It stays EU property until accepted costs or completed work packages clear it, normally at the final payment. If costs are rejected or work is not done, you pay it back. Do not spend it as if it were revenue, and check with your accountant how to book it. AGA Article 22.3.1: pre-financing remains the property of the EU until the final payment.

Planning payroll from the day you win

A Horizon Europe grant is signed about 8 months after the deadline, and pre-financing arrives up to 30 days later. A retroactive start date does not bring the cash forward. Bridge at least 9 months from submission. General Annexes: grant signature about 8 months after deadline. AGA: pre-financing is not paid before the grant agreement is signed, even if the start date is earlier.

Forgetting the MIM deduction

5% to 8% of the whole grant is taken out of the first payment. On a EUR 2M grant at 5% that is EUR 100,000 you will not see until the end of the project. General Annexes: 5% to 8% of the maximum grant deducted from pre-financing for the Mutual Insurance Mechanism; released at final payment.

Expecting 100% before the final report

Pre-financing plus interim payments stop at 90% of the maximum grant. The last 10% arrives only after the final report is approved, 60 to 90 days after you submit it, which itself is due 60 days after the project ends. That can mean 4 to 5 months after the project closes. AGA Data Sheet point 4.2 and Article 22.3: interim payment ceiling, normally 90%; final payment deadline 60 or 90 days.

Adding 25% overhead on subcontracts

The Horizon Europe 25% flat rate does not apply to subcontracting or financial support to third parties. A budget heavy on subcontracting gets much less overhead than founders expect. Digital Europe pays only 7%. General Annexes: indirect costs 25% of eligible direct costs excluding subcontracting and financial support to third parties. DIGITAL call documents: 7% flat rate.

Counting VAT you can recover

If your company deducts VAT in its tax return, that VAT is not an eligible cost. Budget net of VAT. AGA Article 6: deductible or refundable VAT is ineligible; only non-recoverable VAT is eligible.

Covering your 30% with EU-backed national money

Regional ERDF or RRF grants for the same costs count as EU money and are double funding. Purely national grants or private money can cover your share, but the total public funding on the same costs must stay within the most favourable EU rate and the national aid must respect GBER intensities. EIC Accelerator says the 30% must come from the company's own resources. AGA Article 6: costs declared under other EU grants, including Member State grants co-funded from the EU budget, are ineligible. GBER cumulation rule. EIC WP 2026: 30% co-funding from own resources.

Leaving lump sum work packages 90% done

In a lump sum grant a work package is paid only when it is fully completed. 90% done at the interim report earns zero until the end. Design small work packages that finish within one reporting period. Lump sum guidance: no interim payment for partially completed work packages; partial completion settled only at final payment.

How EU grant money works

What you get, what you pay, and when the money lands

EU grants pay a share of your costs, mostly in advance, and hold the last part back until the end. Put in your budget to see the numbers and the cash gap you need to cover.

EU contribution: €1.5M
Your own share: €660k
Paid up front: €1.2M
Worst cash gap: €385k

EU money receivedTotal costs paid out

At signaturePre-financing, minus the insurance contribution€1,155,000
Month 28 of the projectFinal payment€308,000
Month 28 of the projectInsurance contribution returned€77,000

A planning model, not your grant agreement: the Data Sheet in your agreement fixes the real pre-financing, insurance contribution and payment deadlines. A 24-month project with two 12-month reporting periods would normally get about 80% minus MIM.

Horizon Europe advances 160% of the average grant per reporting period: about 80% up front with two periods, about 53% with three. The insurance contribution (the Mutual Insurance Mechanism) is 5% as standard and up to 8%, and comes back with the final payment.

EIC equity: how the investment part works

Ticket: WP 2026: EUR 1M minimum, EUR 10M maximum for the Accelerator. The award decision can add up to EUR 2M flexibility if justified and budget allows. EUR 10M to 30M is available only under EIC STEP Scale Up. The Fund's own guidelines cover EUR 0.5M to 30M across all EIC schemes.
Instruments: Direct equity (ordinary or preferred shares). Convertible loans, bonds, notes. Participation rights and SAFEs. A mix of quasi-equity and equity. Secondary share purchases in specific cases to protect EU interests.
Stake: Target minority stake of generally 10% to 20%. The applicant guide caps it at 25% of voting shares. The Fund can take a blocking stake when the award decision requires it to protect EU interests.
Convertible terms: Bucket 1 standard: about 18-month maturity, 8% fixed interest (accruing, capitalised), 20% conversion discount at 18 months. If no qualified round happens by maturity, conversion is generally at the last round's post-money valuation or lower; a cap may be set case by case.
Co-investors: For direct equity the Fund seeks at least 1:1 matching from other investors and a 1:3 leverage target across the investment life. Co-investors may have to be Qualified Investors. Co-investors are not required at selection: lack of investors at the start does not block the EIC investment.
Valuation: The Fund aligns with the market valuation, in practice the price set by qualified private co-investors in the round. No fixed formula.
Timing: 2 to 6 months from selection to investment decision (indicative). Grant-first companies must request equity at least 6 months before the grant ends; the decision must come during the grant or within 12 months after it ends.

Counting on the EIC equity as guaranteed cash
Winning blended finance is not a signed investment. Due diligence takes 2 to 6 months and can reject you, require co-investors to match, or delay money into milestone tranches. If you stall the round, grant payments can be suspended or the grant terminated.
EIC WP 2026: investment decided by the EIC Fund after due diligence; lack of progress can suspend payment deadlines (MGA Art 29.1(c)) or terminate the grant.
Assuming every programme pays up front
Innovation Fund pays nothing up front and caps payments before financial close at 40% of the grant. Eurostars pays according to each national agency's rules. Model each programme's cash curve separately.
IF25 call text: no pre-financing; up to 40% until financial close. Eurostars FAQ: national rules and procedures.
Under-using pre-financing before an additional pre-financing
Where a grant has additional pre-financing, it is cut if you used less than 70% of the previous one. Slow spending today means less cash tomorrow.
AGA Article 22.3.1: additional pre-financing reduced by the gap between 70% of the previous pre-financing and the amount used.

Combining EU money with other funding

You can mix EU grants with national or private money, but never fund the same cost twice from EU sources, and the total public money on the same costs must stay within the best applicable EU rate (100% for Horizon Europe synergies). National aid is tested on its own against GBER limits; ERDF and RRF count as national state aid but are also EU money for double-funding purposes.

The words in your grant agreement

Maximum grant amount: The ceiling the EU will ever pay you. You can end up with less, never more.
Funding rate: The share of eligible costs the EU pays. 70% means you fund the other 30%.
Eligible costs: Costs the EU accepts: real, recorded, needed for the project, incurred in the project period.
Indirect costs (flat rate): Overheads like rent and admin, paid as a fixed percentage on top of direct costs instead of proven one by one. 25% in Horizon Europe, 7% in Digital Europe.
Co-funding: The part of the budget you pay yourself, from revenue, investors or non-EU grants.
Pre-financing: An advance paid after signature so you can start. It is still EU money until your costs or completed work clear it.
Mutual Insurance Mechanism (MIM): A Horizon Europe safety pot. 5% to 8% of your grant is kept from the first payment and normally returned at the end.
Reporting period: A block of months (often 12 to 18) after which you report and get an interim payment.
Interim payment: A payment after each reporting period for costs or work accepted, except the last period.
Interim payment ceiling: The cap on all payments before the final one, normally 90% of the grant.
Final payment (balance): What is left after the final report is approved. If you were overpaid, you repay instead.
Entry into force: The day the last party signs the grant agreement. Payment clocks start from here.
Time to grant (TTG): Months from the submission deadline to signing the grant agreement.
Lump sum grant: A fixed amount per work package, paid when the work is done. No cost statements or timesheets for payment.
Work package: A chunk of the project with its own tasks, deliverables and, in lump sums, its own price.
Blended finance: EIC Accelerator package: a grant plus an equity investment from the EIC Fund, awarded together.
Convertible loan: A loan that turns into shares at the next funding round, usually at a discount.
Qualified Investor: A professional investor (VC, angel network, corporate fund) the EIC Fund accepts as co-investor and price-setter.
Relevant costs: Innovation Fund term: the extra cost of your low-carbon project compared with business as usual, over capex and 10 years of operation.
Financial close: The point where all financing for a big project is signed and committed. Innovation Fund pays at most 40% before it.
Double funding: Getting two EU-funded grants for the same cost. Not allowed.
State aid / GBER: Rules on national public support to companies. GBER sets how much aid countries can give without asking Brussels. EU grants paid directly by the Commission are not state aid, but count when adding up total public funding.
De minimis: Small aid a country can give without state aid checks: up to EUR 300,000 per company over any 3 years (Regulation 2023/2831).
Seal of Excellence: A label for proposals that passed EIC or Horizon Europe thresholds but were not funded. Some countries fund Seal holders from their own or regional budgets.
