Terms of use

Plain terms for a plain site. Effective 23 September 2026.

Using the site

CalcRabbit provides free calculators and written guides. By using the site you agree to these terms. If you don't agree, please don't use it. We may change the terms by updating this page; continuing to use the site after a change means you accept it.

Estimates, not advice

Every number the site produces is an estimate based on the figures you enter and the rates we publish. We take real care to keep the rates current and the arithmetic exact, and we date and source them so you can check. Even so, platforms change fees without notice, tax rules have exceptions, and your situation may differ from the assumptions a calculator makes. Nothing on the site is financial, tax, legal or medical advice, and it isn't a substitute for a lender's loan estimate, an accountant, or a doctor. Decisions you make using the site are yours.

Health calculators

The health calculators (BMI, body fat, daily calories, calorie deficit, macros and running pace) and the health guides are general information for healthy adults. They are not medical advice: they don't diagnose, treat or prevent any condition, and they don't replace a doctor, registered dietitian or other qualified health professional who knows your history. Their formulas are population averages that can be off for an individual, and they aren't designed for anyone who is pregnant or breastfeeding, under 18, or managing a medical condition or an eating disorder. Check with a professional before changing your diet, exercise or weight, and never delay or ignore medical advice because of something you read here. In an emergency, call your local emergency number.

Accuracy and availability

The site is provided as is. We don't promise it will be error-free or always available, and to the fullest extent allowed by law we aren't liable for losses arising from use of the site or reliance on its results. If you find a mistake, please tell us; we fix confirmed errors quickly and note the date on the affected page.

Your use of the calculators

You're welcome to use the calculators for personal and business purposes and to share links to results. You may not scrape the site at a rate that degrades it for others, attempt to interfere with its operation, or use the contact form to send spam or abuse.

Content and copyright

The text, guides, design and code of the site belong to CalcRabbit unless otherwise stated. You may quote short excerpts with a link back to the page. Marketplace names and logos belong to their owners and are used only to identify the fee schedules being calculated; CalcRabbit is not affiliated with or endorsed by eBay, Poshmark, Mercari, Depop, Etsy, PayPal, Stripe or any other company mentioned.

Advertising

The site is funded by advertising. Ads are served by Google and are labelled as ads; we don't endorse what's advertised, and clicking one takes you to a site we don't control. How advertising cookies work is described in the privacy policy.

Links to other sites

We link to platform fee pages, government sources and similar references. We aren't responsible for their content or for changes to it after we last checked.

Governing law

These terms are governed by the laws of the United States and the state in which CalcRabbit operates, without regard to conflict-of-law rules.
