For website owners & developers
Want to use our calculators on your own site? We offer easy-to-embed widgets and bulk licensing options for publishers and bloggers. Whether you need a single embeddable tool or a set of branded calculators, we provide a neat HTML/JS snippet that fits into standard pages and works responsively. Custom calculator development and white-label packages are available — contact us for details.
Accuracy & transparency
Our calculators use well-known formulas and industry-standard assumptions. Where a calculation depends on assumptions (tax rules, rates, recommended defaults) we include explanatory notes and show the formulas used so you can review and adapt results to your situation. ArunCalc is intended for informational use and not a substitute for professional advice.
Accessibility & privacy
We design tools to be accessible and keyboard-friendly. Most calculators run entirely in your browser — inputs and results are not shared with third parties unless you explicitly use a share/export feature. For more on data and cookies, see our Privacy Policy.
Community & contributions
ArunCalc grows with feedback from users like you. If you spot a bug, want a new calculator, or have an improvement idea, please reach out. We review community requests regularly and prioritize additions that will help the most users.
