About Us

grades-calculator.us is a free online grade calculator built for students, parents, and teachers in the United States. No sign-up, no fees, no hassle — open the page, enter your scores, and get your percentage, letter grade, and GPA instantly.

What We Offer

Our calculators cover the grading situations US students actually face:

  • Grade Calculator — percentage and points modes with optional per-assignment weights.
  • Final Grade Calculator — find out what score you need on your final exam to reach your target grade.
  • Easy Grader — a teacher-friendly tool that converts wrong answers into percentage, letter grade, and GPA.
  • Average Grade Calculator — average your grades by percentage, points, or letter grade.

Alongside the tools, we publish in-depth guides on the US grading system — weighted vs. unweighted grading, GPA scales, and worked examples — so you understand the math behind your grades, not just the result.

Who We Are

grades-calculator.us was created by Muhammad Umer Shuaib, an educator with a background in teaching and academic research in mathematics. His published research is publicly listed on his Google Scholar profile. The site grew out of a simple observation: too many students don’t know where they stand until the semester is over. We built the calculator we wished every student had — accurate, transparent, and free.

Why Free?

Education tools should be accessible to everyone. The site is supported by unobtrusive advertising, which lets us keep every calculator and guide completely free without accounts or paywalls. How advertising works on our site is explained in our Privacy Policy and Cookie Policy.

Our Commitment to Accuracy

Our calculators use the standard formulas taught in US schools — the same weighted-average math your professors use. We show our work: guides include step-by-step examples so you can verify every result. If you ever spot an error, please contact us — we fix mistakes quickly.
