Vendor Loan: Function, Risks and Fair Structuring

A vendor loan is a part of the purchase price that the seller defers for the buyer: the buyer does not pay this portion immediately but later, with interest and in instalments. It closes financing gaps, bridges differing price expectations and signals confidence in the company — but shifts risk from the buyer to the seller.

Structured properly, it can make a sale possible that would otherwise fail on financing. Structured badly, it becomes a loss-making deal. How amount, security and subordination are fixed therefore belongs in the purchase price structure with a vendor loan in the sales process — not in a renegotiation shortly before the notary appointment.

How amount and security are set within a sale process is covered under selling your company.

What is a vendor loan?

Instead of receiving the full purchase price at closing, the seller leaves a portion as a loan. The buyer repays this amount over an agreed term, with interest. Economically, the seller finances a part of his or her own sale. Legally it is a loan within the meaning of § 488 BGB — with all the questions of maturity, termination and security that come with it.

Whether the buyer can service the deferred portion from current earnings is a valuation question: deriving the buyer's debt service capacity from the business valuation is the first step before percentages are discussed.

Vendor loan at a glance

A vendor loan is a part of the purchase price that the seller defers, which the buyer repays later in instalments with interest; the seller thereby becomes the lender to his own buyer. The key points:

Feature	Structure
Lender	the seller
Borrower	the buyer or its acquisition vehicle
Repayment	in instalments or as a bullet, with interest, over an agreed term
Ranking	often subordinated to bank financing, details in the section on the legal position 2026
Purpose	close a financing gap, bridge differing price expectations
Risk	the seller bears the risk of default

Term, interest and security are negotiated case by case; the table describes the structuring principle, not a market statistic.

Why is it used?

Mostly for three reasons. It closes the gap when the buyer's equity and bank loan do not cover the entire price. It bridges a difference between price expectation and ability to pay. And it signals to the buyer and the buyer's bank that the seller believes in the future of the company.

The situation on the buyer side is tight: according to the DIHK-Report Unternehmensnachfolge 2025, almost four in ten of those interested in a takeover report financing problems to the IHKs. For the previous owner's loan as a financing building block, the IHKs at the same time see more positive than negative signs (DIHK-Report Unternehmensnachfolge 2025, retrieved on 25.09.2026). Which promotional loans successors can additionally use for the takeover is described in KfW loans for business succession.

How high is a vendor loan usually?

Usual is 10 to 20 percent of the purchase price; some presentations name up to 30 percent. For the bank, what matters is less the amount than the structure: only a long-term, subordinated vendor loan counts like equity in the buyer's financing.

The question of term is important. Shorter terms of a few years do occur in practice — but then it generally does not count as economic equity with the buyer's bank. Those who actually want to support the buyer's financing must prepare for a considerably longer commitment and a subordination agreement. That is the price for the deal coming about.

A worked example

Assume a company is sold for EUR 2.0 million. The financing could look like this:

Building block	Amount	Share
Buyer's equity	EUR 200,000	10 %
Vendor loan (subordinated, 10 years, with subordination agreement)	EUR 300,000	15 %
Senior bank loan, partly with a promotional loan	EUR 1,500,000	75 %
Total purchase price	EUR 2,000,000	100 %

Because the vendor loan meets the conditions of a substitute for equity, the bank can count on economic own funds of 25 percent, although the buyer itself contributes only 10 percent. The seller receives 85 percent of the price at closing and the rest over ten years, with interest. Without the vendor loan the buyer would have to raise EUR 300,000 more; often the transaction fails on precisely this. The figures are illustrative.

How does it differ from an earn-out?

Both shift part of the payment into the future — but differently. The vendor loan is a fixed amount with interest and a repayment schedule, independent of how the business develops. The earn-out is tied to future performance and lapses if targets are missed.

Feature	Cash payment	Vendor loan	Earn-out
Payment	immediately at closing	later, in instalments	later, performance-dependent
Amount	fixed	fixed, with interest	variable
Risk for seller	low	default risk	risk of achievement
Purpose	clean break	close the financing gap	bridge the price difference

Legal position 2026: ranking, insolvency and seller reinvestment

The central risk is default: if the buyer does not pay, the deferred money is at risk. Three provisions of the Insolvency Code (Insolvenzordnung) determine how large this risk is legally.

• Agreed subordination: The buyer's bank generally demands a subordination agreement. Claims with agreed subordination are, in case of doubt, satisfied in insolvency proceedings only after all other subordinated claims (§ 39 para. 2 InsO). In return, such a loan does not count as a liability when testing for over-indebtedness (§ 19 para. 2 InsO) — precisely this makes it quasi-equity for the bank.
• Reinvestment makes the loan a shareholder loan: If the seller remains a shareholder in the acquiring company, his or her loan becomes a shareholder loan and is subordinated by law (§ 39 para. 1 no. 5 InsO). Exempt is only the non-managing shareholder with 10 percent or less of the liable capital (§ 39 para. 5 InsO).
• Challenge of repayments: Repayments on a shareholder loan in the last year before an insolvency petition are open to challenge (§ 135 para. 1 no. 2 InsO). Those who have reinvested must therefore reckon with having to repay instalments already received.

It follows that security and ranking questions belong early in the negotiation, and a reinvestment above 10 percent fundamentally changes the risk position of the vendor loan. The structure should be reviewed legally — this is not legal advice.

How is it structured fairly?

Fair structuring means: a market-rate interest as compensation for subordination, a clear repayment schedule, information rights (annual accounts, key figures) and, where possible, private security from the buyer — according to the presentation by IHK Nord Westfalen these are permissible even with a substitute for equity. Rules are also sensible for the case that the buyer resells the company: the loan should then fall due immediately.

The deferred portion should make up a part of the price, not the core. Why a high nominal price with much deferral can be worse than a lower one in cash is shown in Why the purchase price is not everything. Especially in a transfer to employees or non-family buyers, a succession arrangement with staggered purchase price payment is often the only route that is sustainable for both sides.

Tax classification

Three points are important for sellers in Germany and Austria. They do not replace tax advice.

Question	Germany	Austria
When does the gain on disposal arise?	in principle at the time of disposal, also for the deferred portion	to be clarified with the tax advisor
What happens if the deferred purchase price defaults?	On a disposal of a business, retroactive correction of the gain on disposal (BFH GrS 2/92, BStBl. II 1993, 897; § 175 para. 1 sentence 1 no. 2 AO)	to be clarified with the tax advisor
How is the interest taxed?	Capital income, in principle 25 % flat-rate withholding tax (§ 32d para. 1 EStG); with a shareholding of at least 10 % in the paying corporation, regular rate (§ 32d para. 2 no. 1 b EStG)	Interest from loans without a banking transaction is excluded from the special tax rate and subject to the standard rate (§ 27a para. 2 no. 1 EStG 1988)

Sources: BFH GrS 2/92, § 175 AO, § 32d EStG, § 27a EStG 1988 (RIS), retrieved on 25.09.2026.

In practical terms: the seller pays tax on the full gain on disposal, although part of the money flows only years later. The liquidity for the tax must come from the cash portion. This argues for sizing the deferred portion so that the cash portion safely covers tax and life planning.

Frequently asked questions

What is a vendor loan, explained simply?

The seller does not receive part of the purchase price immediately but later in instalments with interest. The seller thereby finances a part of the sale and bears a default risk for it.

How high is a vendor loan usually?

According to IHK Nord Westfalen, 10 to 20 percent of the purchase price is usual; other presentations name up to 30 percent. The higher the deferred portion, the greater the risk for the seller.

How long does a vendor loan run?

That is a matter of negotiation. If it is to count with the buyer's bank as a substitute for equity, IHK Nord Westfalen names a minimum term of ten years, a subordination agreement and no withdrawal of security from the company as conditions.

Is a vendor loan the same as an earn-out?

No. The vendor loan is a fixed amount with interest and a repayment schedule. The earn-out is tied to future targets and can lapse entirely.

What changes if I reinvest?

Your loan then becomes a shareholder loan. It is subordinated in insolvency, and repayments in the last year before an insolvency petition are open to challenge. Exempt are only non-managing shareholders with a shareholding of at most 10 percent (§ 39 para. 5 InsO).

Do I have to pay tax on the deferred purchase price immediately?

In Germany the gain on disposal in principle arises at the time of disposal, also for the deferred portion. If the claim later defaults on a disposal of a business, the gain is corrected retroactively under the case law of the Grand Senate of the BFH. The details belong with the tax advisor.

Why should I give a vendor loan at all?

Because it can make a good sale possible that would otherwise fail on financing — and because it signals confidence, which supports the overall price. What matters is fair structuring.

Vendor loan, earn-out, escrow — the building blocks of the purchase price structure are explained in the glossary of M&A terms.

How the agreed company value becomes the amount actually paid out is shown in Purchase price mechanics in a company sale. How a vendor loan interacts with promotional loans and guarantees when the company's own management buys is shown in Financing a management buy-out.

Where the vendor loan fits into the overall structure of a buyer's financing — alongside own funds, bank loan and aws guarantee — is shown in Financing a company acquisition. How buyers in Germany typically build up the financing of business succession in Germany is described on our overview page.
