Terms of Use

Last updated April 27, 2026

Acceptable use

Calcly is offered free of charge for personal and commercial use. You may embed our calculators on your own pages via the supplied embed snippet, link to specific calculators, and share result links. You must not attempt to disrupt the service, scrape at volumes that impact other users, or remove the small attribution stripe at the bottom of an embedded calculator.

No professional advice

Calcly's calculators are general-purpose tools intended to help you understand and explore the underlying math. They are not a substitute for advice from a qualified professional — an accountant for tax planning, a financial advisor for retirement decisions, a healthcare provider for medical questions, an engineer for construction or electrical work.

Tax calculators reflect the rates and rules for the year stated on each page. Tax law changes; always verify with the relevant authority (IRS, HMRC, ATO, CRA, etc.) before filing.

Accuracy

We work hard to keep formulas and rate tables correct and up to date. Even so, the service is provided as-is, without any warranty of accuracy, fitness for a particular purpose, or non-infringement. To the maximum extent permitted by law, Calcly and its operators are not liable for any loss arising from your use of the calculators.

If you find a number that looks wrong, please tell us and we'll investigate.

Intellectual property

The Calcly name, design, and software are owned by the operator. Embeds and result links may be shared freely. The underlying formulas — present-value, BMI, tax brackets, etc. — are public domain and not Calcly's to license.

Changes

We may update these terms occasionally. Material changes will be flagged in the changelog; the "last updated" date above reflects the most recent revision.
