Terms of Use

§1 — Scope of Service

The WACC Calculator ("the Tool," "the Service") is a free, browser-based utility that assists users in computing the Weighted Average Cost of Capital (WACC) using the standard CAPM-based formula. The Service is provided at no charge and without the creation of a user account.

The Service includes the following features:

• A four-panel sequential input form covering capital structure, cost of equity (CAPM), cost of debt, and tax rate
• Live formula rendering with user-supplied numeric values substituted in real time
• A 5×5 sensitivity matrix showing WACC outputs across a range of cost-of-equity and cost-of-debt assumptions
• Three quick-fill presets representing common capital structure scenarios
• Browser-local calculation history and draft auto-save (subject to cookie consent)
• Shareable URL generation via URL hash encoding (no server required)
• PDF export of calculation summaries, generated entirely in-browser
• An embeddable <iframe> widget for integration into third-party websites

The Service is provided on an "as-is" basis as a free public utility. We reserve the right to modify, suspend, or discontinue any feature of the Service at any time without notice or liability.

§2 — Eligibility & Access

The WACC Calculator is intended for use by individuals aged 13 and older. By using the Service, you represent that you meet this age requirement. The tool is designed for educational, analytical, and professional reference purposes and is accessible globally without geographic restriction.

No registration, subscription, or payment is required to access any feature of the Service. We reserve the right to restrict access to the Service for any user or region at our sole discretion, including in response to abuse or violations of these Terms.

§3 — Not Financial, Investment, or Legal Advice

WACC is a model-dependent metric. Its accuracy depends entirely on the quality and appropriateness of the inputs you provide. The tool makes no judgment about whether your inputs are:

• Representative of the actual firm or transaction you are analyzing
• Sourced from reliable or current market data
• Appropriate for the specific valuation context (DCF, M&A, LBO, etc.)
• Compliant with applicable accounting standards (GAAP, IFRS) or regulatory requirements

You are solely responsible for verifying the reasonableness of all inputs and for independently validating any outputs before using them to inform any financial, investment, or business decision. We strongly recommend consulting a qualified financial advisor, CFA charterholder, investment banker, or licensed accountant for decisions of material consequence.

Nothing on this website constitutes an offer or solicitation to buy or sell any security or financial instrument.

§4 — Disclaimer of Warranties

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. WE EXPRESSLY DISCLAIM ALL WARRANTIES, INCLUDING BUT NOT LIMITED TO:

• Accuracy: We do not warrant that the mathematical outputs of the tool are free from error. Floating-point arithmetic and rounding in JavaScript may produce minor imprecision.
• Fitness for a particular purpose: The tool is a general-purpose WACC calculator. It may not be appropriate for specialized valuation contexts, regulated industries, or jurisdictions with specific capital cost requirements.
• Uninterrupted availability: We do not warrant that the Service will be available at all times or free from technical errors, CDN outages, or browser incompatibilities.
• Freedom from bugs: Despite reasonable efforts, the tool may contain software defects. You should independently verify all outputs.
• Timeliness: Preset default values (e.g., risk-free rate, equity risk premium) embedded in the tool reflect values at the time of publication and may not reflect current market conditions.

Some jurisdictions do not allow the exclusion of implied warranties. In such jurisdictions, our liability is limited to the minimum extent permitted by law.

§5 — Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL WACC CALCULATOR, ITS OPERATORS, CONTRIBUTORS, OR AFFILIATES BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES ARISING OUT OF OR RELATING TO YOUR USE OF THE SERVICE, INCLUDING BUT NOT LIMITED TO:

• Investment losses or financial harm resulting from reliance on tool outputs
• Business decisions made using WACC estimates generated by the tool
• Loss of data due to browser storage limitations, user error, or LocalStorage clearing
• Inability to access or use the Service due to downtime or technical issues
• Errors in exported PDF documents or shared URL states

IN ALL CASES, OUR TOTAL CUMULATIVE LIABILITY TO YOU FOR ANY CLAIMS ARISING FROM YOUR USE OF THE SERVICE SHALL NOT EXCEED ZERO DOLLARS (USD $0.00), REFLECTING THE FACT THAT THE SERVICE IS PROVIDED FREE OF CHARGE AND NO COMMERCIAL RELATIONSHIP EXISTS BETWEEN YOU AND US.

Some jurisdictions do not allow the exclusion or limitation of liability for consequential or incidental damages. In such jurisdictions, the above limitation applies to the maximum extent permitted by applicable law.

§6 — User-Generated Content & Intellectual Property

The WACC formula itself (WACC = E/V × Ke + D/V × Kd × (1 − T)) is a standard financial model in the public domain. No intellectual property rights subsist in the formula.

The underlying source code, design, layout, copy, and implementation of the WACC Calculator website — including its HTML, CSS, and JavaScript — are the intellectual property of WACC Calculator and its operators. You may not:

• Copy, reproduce, or redistribute the source code of this tool for commercial purposes without written permission
• Reverse-engineer the tool for the purpose of building a competing commercial product that substantially reproduces its design and feature set
• Remove or obscure any attribution, branding, or "Powered by" notices present in the embed widget

Personal, educational, and non-commercial use — including embedding the widget on personal blogs, university course pages, or non-commercial finance resources — is expressly permitted and encouraged under these Terms.

§7 — Acceptable Use Policy

By using the Service, you agree not to engage in any of the following prohibited activities:

• Automated scraping: Using bots, crawlers, or automated scripts to systematically access the Service in a manner that places unreasonable load on CDN resources or circumvents normal browser-based use
• Misrepresentation: Presenting tool outputs as certified financial analysis, audited valuations, or professional investment advice in contexts where such certification is legally required
• Fraudulent use: Using the tool's outputs in connection with fraudulent financial statements, misleading investor materials, or any activity that violates applicable securities laws
• Infringement: Using the Service in a way that infringes the intellectual property rights of any third party
• Interference: Attempting to interfere with, disable, or circumvent the security features of the Service or the CDN resources it depends on
• Embed abuse: Deploying the embed widget on websites that host illegal content, malware, hate speech, or content that violates applicable law

We reserve the right to modify these Terms and restrict access to the Service for users who violate this Acceptable Use Policy, to the extent technically feasible given the client-side nature of the tool.

§8 — Third-Party Resources & Links

The Service loads the following third-party libraries from external content delivery networks: Tailwind CSS (Tailwind Labs), jsPDF (Parallax / cdnjs / Cloudflare), and Google Fonts (Google LLC). These are software libraries used to render and style the tool and to generate PDF exports. Your use of these libraries is subject to their respective licenses and terms of service.

We are not responsible for the availability, accuracy, or content of any third-party resources, CDN services, or external links referenced on this site. The inclusion of a CDN resource does not constitute an endorsement of the provider.

If any third-party CDN resource becomes unavailable (e.g., Cloudflare outage affecting jsPDF), certain features of the tool (specifically PDF export) may cease to function. Core WACC calculation, sensitivity analysis, and share-link features do not depend on third-party CDNs and will remain functional.

§9 — Embed Widget Terms

Subject to these Terms, we grant you a non-exclusive, non-transferable, revocable license to embed the WACC Calculator widget on your website or application using the <iframe> embed code generated by the tool. This license is conditioned on the following:

1. Attribution intact: The "Powered by WACC Calculator" footer text and hyperlink displayed within the embed widget must not be removed, hidden, obscured, or modified. This attribution is a condition of the free embed license.
2. No harmful contexts: You may not embed the widget on pages that contain illegal content, malicious code, adult content (where not age-gated), or content that promotes hatred or discrimination.
3. No misrepresentation: You may not embed the widget in a context that implies the tool outputs are certified, audited, or professionally validated in excess of their actual nature as browser-computed estimates.
4. Your own disclosures: You are responsible for making any privacy disclosures required by applicable law (GDPR, CCPA, etc.) to your own users regarding the embed. The embed widget itself initiates no tracking.
5. Revocability: We reserve the right to revoke this embed license for specific users or deployments at our discretion, including if we determine the embed is being used in violation of these Terms.

The embed widget functions identically to the main tool in terms of calculation logic, with the sensitivity matrix, navigation, and advertisement slots hidden to preserve vertical space in the embedded context.

§10 — Changes to These Terms

We reserve the right to modify these Terms of Use at any time. When we make material changes, we will update the "Last updated" date at the top of this page. It is your responsibility to review these Terms periodically.

Your continued use of the Service after any modification constitutes your acceptance of the updated Terms. If you do not agree to the revised Terms, your sole remedy is to discontinue use of the Service.

Given the free, no-account nature of the Service, we have no mechanism to notify individual users of changes via email. We recommend bookmarking this page if you wish to track updates.

§11 — Governing Law & Dispute Resolution

These Terms of Use shall be governed by and construed in accordance with the laws of [Your Jurisdiction], without regard to its conflict-of-law provisions.

Any dispute arising out of or relating to these Terms or your use of the Service shall first be attempted to be resolved informally by contacting us at legal@finvaluate.com. We will endeavor to respond within 30 calendar days.

If informal resolution is not achieved within 60 days, disputes shall be subject to the exclusive jurisdiction of the courts located in [Your Jurisdiction]. You waive any objection to the exercise of jurisdiction over you by such courts.

Notwithstanding the foregoing, given that the Service is provided free of charge, you agree that any claims against us shall be pursued only on an individual basis and not as a plaintiff or class member in any purported class action or representative proceeding.
