International damage calculation is the systematic quantification of financial damage for litigation or arbitration. At Musch Legal, we work with financial experts for damage calculations in major disputes. Methods vary: direct costs, lost profits via DCF or multiples, replacement value, before-and-after analysis. For damage claims exceeding 250,000 euros, a detailed calculation accompanied by an expert report is almost always required.
What is the legal issue? (Which method do you choose?)
Damage calculation requires the selection of a method appropriate to the type of damage and the evidence. For direct damage: actual costs with substantiation. For lost profits: discounted cash flow (DCF), multiples method, historical margin approach. For loss of value: before-and-after comparison. The method must be legally substantiated and factually defensible. Incorrect method leads to rejection or significant reduction of claim.
What does the law say? (Which calculation principles apply?)
Under Dutch law, Article 6:97 BW: damages are assessed in the manner that most closely corresponds to their nature. Article 6:104 BW: assessment of damages for lost profits by method. Under CISG Article 74: extent of damage equal to foreseeable loss. Under English law: Hadley v Baxendale test. For experts, Article 194 Rv (judicially appointed) or IBA Rules Rule 5 (party-appointed). International standards such as IFRS, US GAAP, and valuation standards (RICS, IVSC).
For future loss discounting with an appropriate discount rate.

What risks do companies face? (What goes wrong in damage calculation?)
Insufficient evidence renders claim dismissible. Incorrect method (DCF without substantiation of growth) leads to reduction. Unfamiliarity with foreseeability under Section 74 CISG limits compensation. Non-mitigation under Section 6:101 of the Dutch Civil Code reduces the claim. For large claims without an expert report: the judge or arbitrator may estimate at a low upper limit. Inflated claims damage credibility.
Practical example from our practice (How did we calculate 4.5 million euros in damages?)
Musch Legal represented a Dutch manufacturer with a large Belgian contract that was terminated unilaterally. We worked with a forensic accountant on the damage assessment: direct costs (300,000 euros in investments made), lost profits via DCF (3.8 million euros net present value of the remaining 5-year contract period) plus mitigation costs (400,000 euros in alternative customer acquisition). Total claim 4.5 million euros with expert report. The ICC Tribunal fully accepted the methodology; final decision 4.1 million euros in compensation.
What can you do? (How do you build the substantiation of damages?)
Document damages by category from the first incident: direct costs, lost profits, mitigation. For claims exceeding 250,000 euros: engage a forensic accountant. Combine methods for robustness (DCF + multiples for sanity check). Substantiate foreseeability via pre-contractual communication. Document mitigation measures. For proceedings: prepare the expert report in a timely manner. Engage Musch Legal with financial experts.
