Frequently Asked Questions About CalcHub

Who created CalcHub?

CalcHub was built by developers, financial analysts, and health professionals frustrated by inaccurate, paywalled calculator tools. Our mission: professional-grade calculation tools, free for everyone.

How does CalcHub make money if everything is free?

We are supported by non-intrusive display advertising. No pop-ups, no auto-playing video, no interstitials — ads are placed only where they don't interfere with calculator use.

How often are calculators updated?

We update whenever underlying standards change — IRS tax brackets annually, federal loan rates as they change, USDA guidelines on their review cycle. Each calculator shows its "Last Updated" date.
