In Germany, a bank loan is won or lost on the plan behind the idea. A loan officer reads dozens of business plans a month and decides in minutes whether yours is fundable. This guide walks through what a bank and the main German funding programs expect, with the numbers that actually move a decision.
What does a bank actually want to see in a business plan?
A bank lends against repayment ability, so the reviewer looks for evidence that your revenue will cover the loan installments with room to spare. That means a defined market, a realistic sales ramp, and a finance section that ties every euro of funding to a use. Vague optimism gets filtered out fast. For founders sizing up the market, this overview of the AI startup landscape in the DACH region helps you place your own segment.
Concretely, a fundable plan answers four questions on the first two pages: what you sell, who pays for it, how much capital you need, and when the loan is repaid. Most house banks (the Hausbank that channels public loans) expect you to bring roughly 15 to 20 percent equity before they add debt on top. With that equity ratio and a coherent three-year forecast, you already stand ahead of most applicants.
- A one-page summary a reviewer can grasp in 60 seconds.
- A market section with a named customer segment, never "everyone".
- A finance plan with capital requirement, financing mix, and a liquidity forecast.
- A repayment schedule that survives a weak first year.
Which funding fits your start: KfW, a startup grant, or a subsidy?
Germany has three broad routes, and they stack rather than compete. Picking the right mix before you write saves you a rewrite later.
The KfW ERP-Gründerkredit StartGeld covers up to 125,000 euros per founder, of which up to 50,000 euros can be working capital, and it relieves your house bank of 80 percent of the default risk. That indemnity is why a bank will touch an early-stage case at all. If you are coming out of unemployment, the Gründungszuschuss from the Agentur für Arbeit adds your last ALG I rate plus 300 euros a month for six months, then 300 euros a month for a further nine months, as a non-repayable top-up while you build revenue. Regional grants and guarantee banks (Bürgschaftsbanken) fill the gap when your equity runs thin.
How do you build a finance plan a bank will accept?
The finance plan is where most applications are won or lost, because it is the one section a reviewer can check against reality. Build it as four linked tables: capital requirement, financing, a three-year profit forecast, and a monthly liquidity plan for at least the first 12 months.
Keep the assumptions visible. If you forecast 40 customers in month six at an average of 250 euros, write that down so the reviewer can argue with the number instead of dismissing the whole plan. A profitability forecast (Rentabilitätsvorschau) over three years is standard, and a liquidity plan that never dips below zero shows you can pay installments even in a slow quarter. Our business plan tool builds these tables from your inputs so the maths stays consistent across every version.
Why do funding applications get rejected?
Rejections cluster around a handful of avoidable mistakes. Thin equity comes first: below roughly 10 percent of the capital requirement, a house bank often declines before the plan ever reaches KfW. Inconsistent numbers come second, when the revenue in the text does not match the finance tables.
The rest are process errors: applying to KfW directly when the loan has to run through your house bank, missing the fachkundige Stellungnahme that the Gründungszuschuss requires, or handing in a 40-page document with no summary. A tight 15 to 20 page plan with a clean one-pager wins almost every time. A worked example shows the finished shape, and a free bank-ready template gives you the skeleton to fill.
How much equity do I need for a bank loan?
Most house banks expect roughly 15 to 20 percent equity against the capital requirement. Below about 10 percent, many decline before the case reaches KfW.
Can I get KfW StartGeld without a bank?
No. Under the Hausbankprinzip the loan runs through your house bank, which forwards the application to KfW. You cannot apply to KfW directly.
How long does approval take?
A house bank decision usually takes a few weeks once the plan is complete. Missing documents or inconsistent numbers are the main cause of delay.
Is the Gründungszuschuss a loan?
No, it is a non-repayable top-up from the Agentur für Arbeit. It is a discretionary benefit and requires a fachkundige Stellungnahme on your plan.
How long should the business plan be?
Around 15 to 20 pages plus a one-page summary and a finance appendix. A concise plan with a clean summary reviews better than a long one.
