International Arbitration Cost Calculator

How to Use This Tool

Start by entering your dispute amount and selecting the applicable currency for your case. Choose your arbitral institution from the dropdown, as fee structures vary significantly between bodies like the ICC, LCIA, and SIAC.

Select the number of arbitrators assigned to your case, then enter the estimated daily rate per arbitrator and total number of hearing days. Next, fill in your legal counsel’s hourly rate and total estimated billable hours for the arbitration.

Click the Calculate Costs button to generate a detailed breakdown. Use the Reset Form button to clear all inputs and start over. You can copy your full results to your clipboard using the copy button in the results section.

Formula and Logic

This calculator uses simplified, publicly available fee schedules from major arbitral institutions to estimate costs. The core calculation logic is as follows:

• Arbitrator Fees = (Arbitrator Daily Rate) × (Number of Hearing Days) × (Number of Arbitrators)
• Administrative Fees = (Dispute Amount × Institution Fee Percentage) or (Institution Minimum Fee), whichever is higher
• Legal Fees = (Legal Counsel Hourly Rate) × (Estimated Total Legal Hours)
• Total Hearing Costs = Arbitrator Fees + Administrative Fees
• Total Arbitration Costs = Total Hearing Costs + Legal Fees

Administrative fee percentages and minimums are based on 2021–2023 public fee schedules for each institution. Ad hoc (UNCITRAL) proceedings use a nominal fixed administrative fee estimate, as no institutional fees apply.

Practical Notes

Arbitration costs vary widely based on jurisdiction, arbitrator seniority, case complexity, and regional fee standards. The estimates generated by this tool do not account for additional common costs including:

• Travel and accommodation expenses for arbitrators, counsel, and witnesses
• Expert witness fees, translation services, and document production costs
• Post-hearing briefs, evidentiary expenses, and enforcement proceedings

Jurisdiction-specific rules may apply: for example, LCIA proceedings are governed by English law, while SIAC proceedings follow Singaporean arbitration rules. Fee schedules are updated regularly by institutions, so always verify current rates directly with your chosen arbitral body.

This tool does not constitute legal advice. Always consult a qualified attorney specializing in international arbitration for case-specific cost planning and compliance guidance.

Why This Tool Is Useful

International arbitration is often preferred for cross-border disputes due to its neutrality, but cost uncertainty can make budgeting difficult for individuals and small businesses. This tool provides a quick, accessible estimate to help you:

• Plan financial reserves for pending or potential arbitration proceedings
• Compare cost implications of different arbitral institutions and arbitrator configurations
• Negotiate fee arrangements with legal counsel and arbitrators using data-backed estimates
• Evaluate whether arbitration is a cost-effective dispute resolution option for your case

Frequently Asked Questions

Are these cost estimates legally binding?

No, all results from this tool are rough estimates for planning purposes only. Actual costs may vary based on case-specific factors, institutional fee changes, and unforeseen procedural developments. They do not constitute a fee quote from any arbitral institution or legal professional.

How do I find the correct arbitrator daily rate for my case?

Arbitrator rates depend on seniority, specialization, and region. Junior arbitrators may charge $1,000–$2,000 per day, while highly experienced senior arbitrators in major financial hubs can charge $5,000 or more per day. Check arbitral institution panels or legal directories for typical rate ranges in your jurisdiction.

Do I need to include legal fees for the opposing party?

This tool only estimates your side’s legal fees. Many arbitration rules allow the prevailing party to recover legal costs from the losing party, but this is not guaranteed. Consult your attorney to understand cost recovery options in your specific case.

Additional Guidance

When using this tool for official planning, cross-verify all inputs with your legal team. Dispute amounts should reflect the total claimed amount, including interest and costs, not just the principal sum in dispute.

If your case uses ad hoc (UNCITRAL) rules, note that you will be responsible for appointing arbitrators and managing administrative tasks yourself, which may incur additional unlisted costs. For small disputes (under $100,000), consider whether expedited arbitration procedures are available, which often have lower fee caps.

All institutional fee schedules are subject to change without notice. Always check the latest fee table on the official website of your chosen arbitral institution before finalizing budgets.
