Terms of Use

By using stats.nowcalculator.net (the "Site") you agree to these terms. If you do not agree, please do not use the Site.

1. What the Site provides

The Site offers free, browser-based statistics calculators — including standard deviation, mean/median/mode, probability, z-score, fraction, permutation and combination, sample size and percent error calculators — along with related educational content and world-statistics reference material. All calculations are performed within your browser; the figures you enter are not transmitted to or stored on our servers.

2. Educational use

The Site provides calculators and general information for educational and reference purposes only. Statistics presented in our content are approximate figures compiled from public sources (such as the UN, IMF, World Bank, ITU and UBS) and change over time; verify current details with the original source before relying on them for academic, professional or research use.

3. Accuracy and limitations

Our calculators use standard statistical formulas, but very large or very small values may be subject to floating-point rounding, and some tools (such as the z-score percentile) use standard approximations. World-statistics figures are approximate and change over time. Verify important results independently and use them at your own discretion.

4. Acceptable use

You may use our calculators freely for personal and commercial purposes. You may not copy, scrape, republish, or resell our written content or calculator code without permission.

5. Third-party links

The Site links to external websites, such as banks, scholarship programs and credit bureaus, for your convenience. We do not control and are not responsible for their content, offers, or practices.

6. Availability

We may change, add, or remove calculators and content at any time, and the Site may occasionally be unavailable for maintenance.

7. Limitation of liability

To the fullest extent permitted by law, NowCalculator is not liable for any loss or damage arising from your use of, or reliance on, this Site or any third party it links to.

8. Changes

We may update these terms from time to time. Continued use of the Site means you accept the current version.

9. Contact
