We read every message. Whether you found a bug, want to suggest a calculator, or have a business inquiry β we are here to help.
We aim to respond within 24β48 hours on business days.
A calculator is only valuable if it performs computations with absolute accuracy. While we run extensive programmatic audits on all algorithms before deploying them, edge cases can occur due to local browser settings, unexpected input combinations, or changes in regional regulatory guidelines (like tax slabs or insurance rebate updates).
If you suspect a calculation on our platform is producing an incorrect result, we encourage you to submit a bug report. To help our engineering team identify and resolve the issue quickly, please structure your report with the following details:
We are constantly expanding our collection of tools. If you need a calculator that is not currently available on our platform, we would love to build it for you. We prioritize calculator requests that serve a broad audience, solve complex calculations, or save time for students and professionals.
When suggesting a new tool, please provide as much context as possible. Helpful details include: the purpose of the calculator, the inputs required, the expected outputs, the mathematical formulas or guidelines, and links to official documentation (such as government policy papers or scientific research) that define the calculation logic. Our team will review the proposal and, if approved, design, test, and launch the tool.

All calculations on our platform are executed using standard client-side JavaScript. If you want to understand how a specific formula is implemented in our code, you can inspect it using your browser's Developer Tools (right-click the page and select "Inspect"). If you have questions about our mathematical models, feel free to send us a message.
If the form button displays "Sending..." without presenting a success confirmation, ensure that your browser's internet connection is stable and that JavaScript is enabled. If you use strict privacy plugins or ad blockers, they may occasionally block local form submission scripts. If the form continues to fail, you can email us directly at hello@allfreecalculators.com.
No. If we decide a suggested calculator is a valuable addition to our public directory, we will build, test, and publish it completely free of charge. If you need a private, custom-branded calculator widget for your corporate website, please contact our business team to discuss development costs.
We take user security and privacy seriously. Because we perform all calculations locally in the user's browser, we do not store sensitive personal information on our servers.
