Terms of Service: Use Conditions & Liability Disclaimer

Last updated: 2026-05-02.

By using commercialleasecost.com, the calculator, or the AI Negotiation Coach, you agree to these terms.

What we provide

• The commercial lease cost calculator modeling total cost of occupancy
• Per-metro market data for 25 US metros, refreshed quarterly
• Editorial guides on commercial lease structure, negotiation, and economics
• The AI Negotiation Coach generating draft counter-offer language

What we don’t provide

• Financial, legal, or fiduciary advice
• Real estate brokerage services
• Legal services
• Accounting or tax advice
• Specific recommendations of brokers, attorneys, or vendors

For commercial lease decisions, always consult a licensed commercial real-estate broker, real-estate attorney, and (where applicable) CPA.

Accuracy of information

We make reasonable efforts to verify all market data and citations. Despite this:

• Market data is sourced from third-party brokerage reports; we don’t independently audit those underlying reports
• Per-metro benchmarks reflect medians or ranges; your specific deal may differ
• The calculator is a tool with assumptions and simplifications; exotic deal structures may not fit
• Information may become outdated between quarterly verification cycles

We are not liable for decisions made based on the information published on the site.

Calculator and AI Coach use

Calculator

The calculator is provided as-is. Inputs are stored locally in your browser unless you explicitly share results. We don’t collect calculator inputs server-side except for anonymized analytics.

The calculator does not handle every commercial lease scenario. For exotic structures (build-to-suit, ground lease, percentage rent only, sublease economics), engage a tenant rep broker.

AI Negotiation Coach

The AI Coach generates draft counter-offer language using Google’s Gemini 2.5 Flash. It is not a substitute for:

• A licensed real-estate attorney
• A licensed tenant rep broker
• A specific deal review

Output disclaimer (always included): “This tool provides general information only and is not legal, financial, or fiduciary advice. Commercial real-estate is highly local and deal-specific. Have a licensed real-estate attorney and a tenant-representation broker review your specific lease before signing.”

The AI Coach has rate limits. We may suspend access for abusive use or excessive volume.
