Yes, all tools on Calcuzy are completely free. No payment or account is required to use any tool.
Our calculators use verified formulas and are regularly updated to ensure accuracy. Financial tools incorporate current tax laws, health calculators follow medical guidelines, and all mathematical computations are precision-tested. However, always consult professionals for critical decisions.
We add new tools over time based on user feedback and practical needs. Check the All Tools page or contact us if you have a suggestion.
No account required. All tools work instantly without registration. Your calculator inputs stay in your browser—we do not store your calculation results. We use basic analytics (Google Analytics and Vercel Analytics) to understand general site usage. See our Privacy Policy for details.
Calcuzy may use advertising in the future to help keep tools free. Any ads will be kept unobtrusive and will not interfere with tool functionality.

What you will find here
The finance tools— rent affordability, capital gains tax, crypto tax, and property tax—include formulas, worked examples, and links to official sources. They are educational starting points, not professional tax or legal advice.
Health and everyday tools like the BMI calculator, age calculator, and unit converter explain how results are calculated and where the method comes from (for example WHO/CDC categories for adult BMI).
In-depth guides on the blog
For topics that need more context, we publish long-form guides on the Calcuzy blog: rent and the 30% rule, capital gains tax, crypto cost basis, BMI explained, and basic will writing. Every guide links back to a free tool you can use immediately.
How we approach accuracy and privacy
Formulas follow published standards where they exist. Finance and legal tools include clear disclaimers. We describe analytics and advertising practices in our Privacy Policy. If you spot an error or want a new tool, send feedback—many additions on Calcuzy started that way.
