What StudyCalc Is
StudyCalc is a free website of GPA, CGPA, percentage, attendance, and grade-conversion calculators, plus guides that explain the formulas behind each one. There's no account system and no app — everything runs directly in your browser at studycalc.co.
Get in Touch
If you spot an incorrect calculation, find a bug, want to request a new calculator, or have a question about how a formula works, email us directly. There's no contact form on this page — writing to the address below reaches us and nothing else.
Reporting an Error or Requesting a Correction
If you believe a calculator, formula, or guide is wrong, tell us the page URL and what you think is incorrect. We check the underlying formula and, where a guide cites an outside fact (a grading scale, a board policy, a conversion convention), we re-check it against the source the page lists. If the report is confirmed, we fix the live page — we don't just note it and move on.
What Happens to Your Message
Emailing us shares whatever address and content you choose to send — nothing more. We use it only to reply and, if relevant, to fix the page you're writing about. See our Privacy Policy for how we handle data more broadly.
