How much are the damages for late delivery? A cover purchase example
The damage covers, in principle, the extra costs the buyer runs up through the delayed or missing delivery. The core case is the cover purchase: once the period has passed without result, the buyer sources the goods elsewhere and claims the price difference. On the case law of the Federal Court of Justice (Bundesgerichtshof, judgment of 3 July 2013, VIII ZR 169/12), the additional cost of a cover purchase is damages in lieu of performance under Sections 280(1) and (3), 281 BGB, not merely delay damages. So the buyer can claim these extra costs only if it has first let the grace period pass, or if the grace period was dispensable, and it can no longer insist on performance alongside.
The example below serves only to illustrate the method of calculation.
Under the original contract, 100 special pumps at €2,000 each cost a total of €200,000. After the grace period expires, the buyer purchases the same quantity elsewhere at €2,300 per unit, resulting in a total price of €230,000. The direct additional cost of the cover purchase is therefore €30,000. If a further €4,000 is incurred for express freight and necessary retooling, the simplified example produces damages in lieu of performance of €34,000.
Alongside this, the buyer can assert the pure delay damages, so far as they are not already absorbed in the cover purchase, for example financing costs for the bridging period or the interest loss on advance payments already made.
On statutory default interest, a distinction has to be drawn. The higher rate of nine percentage points above the base rate (Basiszinssatz, Section 247 BGB) under Section 288(2) BGB applies only to monetary claims between businesses, that is, to a company's own payment claim, and in the supply relationship it mainly hits the supplier against a defaulting buyer. At a base rate of 1.52 percent (since 1 July 2026), that works out at a default interest of 10.52 percent per year.
For the buyer's own monetary claims against the supplier, such as reclaiming an advance payment after withdrawal or a quantified sum of damages, the general rate of five percentage points above the base rate under Section 288(1) BGB applies instead, because these lack the character of a payment claim.
For monetary claims, Section 288(5) BGB adds a flat sum of 40 euros, which, however, is to be set off against any further reimbursement of the costs of pursuing the claim. The buyer must set out and prove the damage specifically; the cover purchase quotes, the invoices and the time of setting the period should therefore all be carefully documented.
