Innovation Loan

In Short

An innovation loan is a low-interest promotional loan from KfW or a regional development bank for innovation projects, applied for via the house bank.

What is an innovation loan?

Innovation loan (in German Innovationskredit) describes a promotional loan that public development banks grant for innovation, research and digitalisation projects. Compared with an ordinary bank loan, such a loan generally offers a reduced interest rate, a longer term and initial repayment-free years in which only interest is paid. In some programmes the development bank assumes part of the default risk. Unlike a grant, it must be repaid and counts as debt capital; individual programmes waive part of it as a repayment grant.

Providers are KfW (Germany's state development bank) and the development institutions of the federal states. Programme names, terms, maximum amounts and conditions change regularly; the current fact sheet applies. For technology companies, the innovation loan sits between bank loan and grant funding. It stands alongside an equity round or covers a capital need for which new shares would be available only at an unfavourable valuation.

Applying for an innovation loan: the house bank principle and release from liability

Most promotional loans are not applied for directly at the development bank but through a credit institution of the company's choice, usually the house bank (the house bank principle). The house bank reviews the project and creditworthiness, submits the application, pays out the loan and administers it during its term. The development bank refinances it, that is, makes the money available to it on favourable terms. The default risk is in principle borne by the house bank. It thus in effect decides whether an application is made at all.

A release from liability changes this calculation. The development bank assumes, vis-à-vis the house bank, a share of the default risk set in the programme, and the house bank is liable only for the rest. In this way, projects become financeable that a bank alone would not carry. For the company, the obligation to repay remains in full: the release relieves the bank, not the borrower.

Even with a release from liability, the house bank generally requires customary bank collateral. This includes real security, that is, rights over specific assets such as a land charge or security ownership of machinery, and personal security such as guarantees. Where real security is lacking, the house bank sometimes requires a guarantee from the shareholders. The guaranteeing shareholder is then personally liable with private assets; the limited liability of the GmbH (German limited liability company) does not protect them in that respect. Scope and consequences must therefore be reviewed legally before signing.

Funding conditions and state aid law

What counts as innovation is set by the respective programme. Typically funded are the development of new or substantially improved products, processes and services as well as digitalisation projects, in part also working capital of innovative companies. Some programmes are tied to features of the company, for example a minimum share of research and development expenditure in total costs, others to the individual project. A common rule is that the application must be filed before the project starts; usually even the conclusion of a supply or service contract counts as the start.

An interest-subsidised promotional loan generally contains state aid, that is, an economic advantage from public funds. Its value does not correspond to the loan amount but to the advantage compared with market terms, above all the interest subsidy and the assumption of risk.

EU state aid law limits how much funding a company may receive. Many promotional loans are granted as de minimis aid, that is, minor aid which, owing to its small amount, need not be notified to the European Commission. The de minimis threshold under the EU regulation in force since 2024 is EUR 300,000 within three years (as of 2026), affiliated companies added together. Other programmes rely on the EU General Block Exemption Regulation, which permits higher amounts for certain projects. Some also offer an aid-free variant that does not use up the state aid ceiling.

State aid ceilings work in two directions. A promotional loan can use up part of the ceiling that is available for other funding. At the same time, the same eligible costs may not be funded multiple times at will, for example through a grant for an R&D project and in addition through the research allowance. The programmes' cumulation rules must therefore be reconciled before the application.

How banks assess young technology companies

With a promotional loan as well, the house bank examines debt service capacity, that is, whether interest and repayment can be borne from the ongoing business. For young technology companies the earnings history for this is often missing. The bank then relies on equity base, liquidity runway, quality of planning and customers who already pay. A funding round completed shortly before works twice: it strengthens the liable equity and shows that expert investors have examined the business model.

As a complement to equity, the innovation loan suits projects that will foreseeably lead to cash surpluses. Examples are a product module for an existing customer base, the automation of a process with measurable cost savings, or the market launch of a version with concrete demand. For development with an open outcome, grants and equity fit better because they require no fixed repayments. Repayment after the repayment-free years should come from operating cash flow, that is, from the cash surplus of the ongoing business, and not from the next funding round.

Worked example: innovation loan for a new product module

A software company with EUR 4 million in annual recurring revenue develops a new product module for existing customers. Through its house bank it receives an innovation loan of EUR 900,000 with a term of eight years, of which two years are repayment-free, followed by six equal annual repayment instalments. The interest rate is assumed at 4.5% per year; a bank loan without promotion with the same repayment structure would cost an assumed 7%. The development bank releases the house bank from 50% of the liability.

  • Interest in years 1 and 2: EUR 900,000 × 4.5% = EUR 40,500 per year
  • Repayment from year 3: EUR 900,000 ÷ 6 = EUR 150,000 per year
  • Debt service in year 3: EUR 150,000 + EUR 40,500 = EUR 190,500, the highest value over the term
  • Debt service in year 8: EUR 150,000 + EUR 150,000 × 4.5% = EUR 156,750
  • Interest in years 3 to 8: The outstanding balances at the start of each year are EUR 900,000, 750,000, 600,000, 450,000, 300,000 and 150,000, together EUR 3.15 million. Interest on this: EUR 3.15 million × 4.5% = EUR 141,750
  • Interest over the term: 2 × EUR 40,500 + EUR 141,750 = EUR 222,750
  • At 7% without promotion: 2 × EUR 63,000 + 7% × EUR 3.15 million = EUR 126,000 + EUR 220,500 = EUR 346,500; interest advantage EUR 123,750
  • Risk of the house bank: 50% × EUR 900,000 = EUR 450,000 instead of the full amount
  • For comparison, equity of the same amount at a pre-money valuation of EUR 12 million (value before the payment): EUR 0.9 million ÷ (12 + 0.9) million = around 7.0% of the shares

Over its term the loan costs EUR 222,750 in interest and no shares. From the third year, however, it requires debt service of up to EUR 190,500 annually, regardless of whether the module brings the planned revenue. It is sustainable if operating cash flow covers this amount even in the cautious planning case. The equity variant requires no debt service but leads to dilution, which spreads every later increase in value over a larger group of shareholders.

Distinction: innovation loan, grant, allowance and venture debt

  • Grant: non-repayable funding on the basis of a grant award notice. The innovation loan, by contrast, rests on a loan agreement with the house bank.
  • Research allowance: tax-based support for research and development that is credited against tax or paid out. It requires neither repayment nor a house bank.
  • Venture debt: private loan to venture-capital-financed companies, usually more expensive and with warrants for the lender. It relies more on the equity investors than on earning power.
  • Subordinated loan: a loan that ranks behind the other creditors and therefore acts like equity from a bank's perspective. Some development institutions of the federal states grant such loans as separate programmes, often without collateral.

Common mistakes

  • Project started before the application. Anyone who has already signed contracts for the project loses eligibility in many programmes.
  • House bank involved too late. Without a bank that supports the application, the promotional loan does not materialise; the conversation belongs at the start of planning.
  • Only the interest rate compared. For a young company, repayment-free years, term and release from liability often weigh more heavily than half a percentage point of interest.
  • Start of repayment not in the plan. When the repayment-free period ends, debt service rises abruptly; if this date falls into the preparation of the next round, it weighs on the negotiating position.
  • Cumulation overlooked. If the same costs are additionally funded through grants or the research allowance, reductions or repayment demands threaten.
  • Regional programmes not checked. The development institutions of the federal states offer their own loans whose terms can be more favourable in the individual case than those of federal programmes.

Frequently asked questions

Which development banks offer an innovation loan?

KfW and several development institutions of the federal states, in each case applied for through the house bank. As of October 2026, the federal programme is called ERP-Förderkredit Innovation (ERP promotional loan for innovation); in July 2025, together with the ERP-Förderkredit Digitalisierung, it replaced the previous ERP Digitalisation and Innovation Loan. In Bavaria, LfA Förderbank Bayern grants the Innovationskredit, successor to the Innovationskredit 4.0. In Baden-Württemberg, L-Bank offers the Innovationsfinanzierung, in Hesse WIBank the HessenFonds Innovationskredit. NRW.BANK funds innovation and digitalisation projects through the promotional loan NRW.BANK.Invest Zukunft.

How long does it take until payout?

As a rule several weeks to a few months. The duration depends mainly on the house bank's credit decision; the development bank's commitment often follows quickly if the application is complete. In liquidity planning, the inflow should therefore be set with a time buffer.

Are there innovation loans without collateral?

Rarely in full. Promotional loans generally require customary bank collateral, which the house bank negotiates. A release from liability lowers its requirements but does not replace its own risk assessment. Without collateral, subordinated loans from individual state development institutions come closest.

Can an innovation loan be combined with an equity round?

Yes, and the sequence often matters. House banks are more willing to support a promotional loan when a funding round has already been completed and equity covers the start-up losses. Investors for their part watch that debt service does not consume the proceeds of the round and that the loan agreement contains no consent requirements that delay future rounds.

What happens to the loan in a company sale?

It is often repaid early. Loan agreements regularly contain termination rights for a change of control, that is, a sale of the majority of shares, and acquirers often switch the financing to their own banks. Whether a promotional loan can be continued depends on the programme conditions and the house bank; until repayment, the outstanding amount counts as financial debt in the purchase price calculation.

Can an innovation loan be considered without several years of annual financial statements?

Yes, individual programmes provide their own criteria for young companies. Under the ERP-Förderkredit Innovation, a small or medium-sized enterprise that has been on the market for less than five years can count as innovative if it has received venture capital (as of October 2026). The house bank then relies more on planning, equity base, team and existing customer relationships.

The Roemer Capital view

When a client prepares a funding round, we check in the financial model whether a promotional loan can take over part of the capital need without costing shares. The benchmark is the cautious planning case: if operating cash flow bears the debt service after the end of the repayment-free years, the loan reduces dilution. If it does not, the loan merely shifts the financing need into a later round.

We schedule the conversation with the house bank in parallel with investor outreach so that the bank can use the round as the basis of its decision. Choice of programme and application lie with the house bank and development institution, the legal and tax review with the company's law firm and tax adviser. Our contribution is the planning calculation on which all parties rely.
