About TotalGrader
Last Updated: July 2026
Why TotalGrader Exists
TotalGrader started with a simple frustration: grading tools online were either cluttered with ads, inaccurate, or built for one narrow use case (just percentages, or just GPA, but never both). As someone who spent time helping tutor students and manage classroom data, I kept building small spreadsheets and scripts to speed up grading — and eventually turned that into a proper set of free, accurate tools anyone could use.
TotalGrader is built around one goal: give teachers, students, and parents fast, transparent, and mathematically accurate grading calculations — without the guesswork.
What We Build
TotalGrader currently offers:
- Grade Calculators — convert raw scores (points, fractions, correct/incorrect counts) into percentages and letter grades using standard, verifiable grading scales.
- GPA Calculators — weighted and unweighted GPA calculations that follow the conversion tables used by most U.S. high schools and colleges.
- Quick Grade Tools — fast lookup tools for common test lengths (10-question, 20-question, 25-question quizzes, etc.) so teachers can grade a stack of papers without re-doing the same math over and over.
Every calculator is built to match the grading scales actually used in classrooms — standard 90/80/70/60 percentage breakpoints by default, with notes where scales commonly vary by school or region.
Our Approach to Accuracy
Grading tools are only useful if the numbers are right. Here’s how we keep TotalGrader reliable:
- Formulas are based on standard academic conversion tables, not arbitrary rounding.
- Every calculator is manually tested against known score/grade pairs before publishing.
- We flag ambiguity. Grading scales differ between schools, countries, and grading policies (e.g., whether a 92% is an A or A-). Where this matters, our tools and articles explain the variation instead of pretending there’s one universal answer.
We’re not a substitute for an official school gradebook or transcript — and we say so clearly in our disclaimer — but for quick, everyday grading math, our tools are built to be dependable.
Who’s Behind TotalGrader
Hi, I’m Ashar Hussain, the developer and maintainer of TotalGrader. I build and maintain the calculators, write the accompanying guides, and personally test each tool before it goes live. My background is in web development, and this site is where that skill meets a genuinely practical need — helping teachers and students spend less time on manual grading math and more time on actual teaching and learning.
I actively update TotalGrader based on feedback: if a calculator doesn’t match your school’s grading scale, or you spot an error, I want to know (see our Contact page) — corrections get made directly, not ignored.
What’s Next
TotalGrader is actively growing. Planned additions include:
- More regional/international grading scale support
- A weighted assignment calculator for full-course grade tracking
- Printable grading charts for classroom use
Thanks for using TotalGrader — if you have a grading scenario our tools don’t cover yet, let us know.
