Welcome to Calculator Expert, operated at www.calculatorexpert.online ("Website", "Platform", "we", "us", or "our").

We reserve the right to modify, suspend, or discontinue any part of the service at any time, with or without notice, without liability to you.

Calculator Expert is intended for personal, non-commercial, educational, and informational use. By accessing our platform, you agree to use it only in ways that are lawful, ethical, and consistent with these Terms. The following summarises what is and is not permitted:

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, CALCULATOR EXPERT AND ITS TOOLS, CONTENT, AND SERVICES ARE PROVIDED ON AN "AS IS" AND "AS AVAILABLE" BASIS, WITHOUT ANY WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED.

We expressly disclaim all warranties, including but not limited to:

• !
  Implied warranties of merchantability — We make no warranty that our service meets any particular standard of quality or commercial utility.
• !
  Implied warranties of fitness for a particular purpose — Our tools are general-purpose and may not be appropriate for all specific use cases.

We invest significant effort in ensuring that all calculators on Calculator Expert use verified, industry-standard formulas sourced from authoritative references. However, we cannot guarantee that every result will be perfectly accurate for every individual situation, and the following limitations apply:

5.1 Financial Calculators

Our financial calculators — including EMI, SIP, Compound Interest, Income Tax, Mortgage, and Retirement calculators — produce estimates based on the inputs you provide and standard mathematical formulas. Actual loan repayments, investment returns, and tax liabilities may differ significantly based on factors including:

• 📌
  Changes in interest rates, tax slabs, or government policies after our last update
• 📌
  Bank-specific fees, prepayment charges, or compounding frequencies that differ from our defaults
• 📌
  Individual financial circumstances not captured by the calculator inputs

Always consult a qualified financial advisor, chartered accountant, or bank before making any financial commitment.

5.2 Health & Fitness Calculators

Our health calculators — including BMI, BMR, Body Fat, Ideal Weight, and Pregnancy Due Date calculators — use globally accepted medical formulas such as the WHO BMI classification, the Mifflin-St Jeor equation, and Naegele's Rule. However, these tools cannot account for individual medical conditions, genetic factors, or variations in human physiology. They are not a substitute for a medical examination. Always consult a licensed medical professional before making health decisions.

5.3 Mathematical & Scientific Calculators

Our math tools aim to be accurate to at least 10 decimal places. Rounding may apply for display purposes. For use in professional engineering, academic research, or precision scientific work, please verify results using a certified computation system.

Calculator Expert is a free platform sustained by advertising revenue. We display advertisements through Google AdSense, a service provided by Google LLC. By using our website, you acknowledge and agree to the presence of advertisements on our platform.

7.1 Google AdSense

Google AdSense uses cookies and interest-based tracking to display personalised advertisements. The specific ads you see are determined by Google's advertising algorithms based on your browsing history, location, and interests. Calculator Expert has no direct control over the specific advertisements Google displays on our pages.

7.2 Our Advertising Standards

• ✓
  We only display advertisements through Google AdSense — a globally trusted advertising platform with strict content policies.
• ✓
  We do not accept direct advertisements from advertisers whose products or services are harmful, deceptive, or illegal.
• ✓
  Advertisements are placed in clearly designated areas and do not obscure or interfere with calculator functionality.
• ✓
  We clearly distinguish between editorial content and advertising to avoid misleading our users.

7.3 Opting Out of Personalised Ads

If you prefer not to see personalised advertisements, you can opt out through your Google Ads Settings or by installing the Google Analytics Opt-out Browser Add-on. Note that opting out of personalised ads will not remove advertisements from our site — it will make them less relevant to your interests.

Calculator Expert may contain links to third-party websites, resources, or services that are not owned or controlled by us. These links are provided for your convenience and informational purposes only.

We have no control over and assume no responsibility for the content, privacy policies, practices, or accuracy of any third-party website. We do not endorse any third-party website or its content simply by linking to it. You access any linked third-party website entirely at your own risk.

We strongly recommend that you read the Terms of Service and Privacy Policy of any third-party website you visit from a link on our platform. Calculator Expert is not responsible for any loss or damage arising from your use of, or reliance on, any third-party website, product, or service.

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, CALCULATOR EXPERT, ITS OWNERS, OPERATORS, EMPLOYEES, AGENTS, AND AFFILIATES SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES ARISING FROM OR RELATED TO YOUR USE OF OUR WEBSITE OR SERVICES.

This includes, without limitation, damages for:

Our total aggregate liability to you for any and all claims arising out of or related to your use of Calculator Expert shall not exceed the amount you paid us in the twelve months preceding the claim — which, since our service is free, shall be zero (₹0 / $0).

Some jurisdictions do not allow the exclusion of implied warranties or limitation of liability for consequential damages, so some of the above limitations may not apply to you.

Your use of Calculator Expert is also governed by our Privacy Policy, which is incorporated into these Terms by reference. By agreeing to these Terms of Service, you also agree to our Privacy Policy.

In summary: we do not collect the values you enter into any calculator. All calculation data is processed entirely within your browser and is never transmitted to our servers. We collect only anonymised, aggregated usage data through Google Analytics to understand how our website is used and improve our tools.

For complete details on how we handle your data, use cookies, and display advertising, please read our full Privacy Policy.

We reserve the right to terminate, suspend, or restrict your access to Calculator Expert — in whole or in part — at any time, without prior notice, for any reason, including if we believe you have violated these Terms of Service or engaged in conduct that is harmful to other users, third parties, or the integrity of our platform.

Upon termination of access, the following provisions of these Terms will survive and remain in effect: Intellectual Property Rights (Section 6), Disclaimer of Warranties (Section 4), Limitation of Liability (Section 9), and Governing Law (Section 12).

Since Calculator Expert does not require account registration, "termination" in this context primarily refers to our right to block an IP address, restrict specific features, or take legal action against users who violate these Terms.

These Terms of Service shall be governed by and construed in accordance with applicable international laws and regulations, without regard to conflict of law provisions. Calculator Expert is an online platform accessible globally, and we are committed to operating in compliance with the legal requirements of the jurisdictions in which our users reside.

12.1 Dispute Resolution Process

• 1
  Informal Resolution First: Before initiating any formal dispute, you agree to contact us at support@calculatorexpert.online and attempt to resolve the dispute informally for at least 30 days. We believe most concerns can be resolved through honest, direct communication.
• 2
  Mediation: If informal resolution fails, both parties agree to attempt good-faith mediation through a mutually agreed neutral mediator before pursuing any litigation or arbitration.
• 3
  Arbitration: If mediation is unsuccessful, disputes shall be resolved through binding arbitration under internationally recognised arbitration rules, conducted in English, with proceedings held virtually wherever possible.

You are responsible for ensuring your use of Calculator Expert complies with the laws applicable in your own country or region. Calculator Expert makes no representation that its website or content is appropriate or legally permitted in every jurisdiction worldwide.

We reserve the right to modify, update, or replace these Terms of Service at any time at our sole discretion. When we make material changes, we will update the "Last Updated" date at the top of this page. We may also provide more prominent notice of significant changes through a banner on our website.
