❓ FAQ

How is letter grade determined?

A = 90–100%, B = 80–89%, C = 70–79%, D = 60–69%, F = below 60%.

Is my data saved?

Yes — grades are saved in your browser’s local storage. Nothing leaves your device.

Can I use this offline?

Absolutely. After the first load, everything works offline.

How does the Final Exam Predictor work?

Formula: Required = (Desired − Current × (1 − Weight)) ÷ Weight. It calculates exactly what you must score on the final to reach your target grade.

How do weighted grades work?

Each category’s grade is multiplied by its weight percentage. The weighted average = sum of (grade × weight) ÷ total weight.

Grade Calculator Pro: The Ultimate Free Tool for Students and Teachers

Whether you’re tracking high school assignments, calculating your college GPA, or trying to figure out what you need on a final exam, the Grade Calculator Pro brings everything together in one easy-to-use, fully offline web app. No sign-ups, no ads, just fast, accurate grade math that you can trust.

What Makes This Grade Calculator Different?

This isn’t just a simple percentage converter. The tool combines a complete grade calculator, final exam predictor, weighted grade calculator, assignment tracker, and performance analytics dashboard — all in a clean, mobile-friendly interface. Every calculation happens right in your browser, so your data stays private and the tool works perfectly even without an internet connection.

Key Features of the Grade Calculator Pro

Multi-Subject Grade Table

At the heart of the tool is an interactive table where you can enter up to as many subjects as you need. For each subject you provide:

Earned points – how many points you’ve scored so far
Total possible points – the maximum score for that category or assignment
Weight percentage – how much that subject contributes to your overall grade

The calculator instantly shows each subject’s percentage and letter grade, and computes your overall percentage, GPA, and performance rating. You can switch between grading scales — A–F (90–100% = A), percentage only, a 4.0 GPA scale, or a 5.0 GPA scale — with a single click.

Final Exam Predictor (Final Grade Calculator)

One of the most powerful features students rely on. Enter your current grade, your target final grade, and how much the final exam is worth, and the final exam predictor will tell you exactly what score you need on the exam. It doesn’t stop there — the tool gives you a difficulty rating (from “Easy” to “Very Hard”) and shows you clearly if your goal is already secured or mathematically impossible. No more guessing; you walk into exam day with a real plan.

Weighted Grade Calculator

Many courses use weighted categories (homework, quizzes, midterms, projects). The dedicated weighted grade calculator lets you add any number of categories along with their grade percentages and weight percentages. It then calculates your true weighted average instantly. This is especially useful for college students whose syllabi break grading down by category weight.

Assignment Tracker

Beyond calculating grades, the tool helps you stay organized. The assignment tracker lets you log individual tasks with a status (Pending, Done, or Late) and an estimated grade. You’ll see a live summary of how many assignments you’ve completed, your average estimated grade, and a visual progress bar — perfect for keeping on top of a busy semester.

Performance Analytics

Turn your raw data into meaningful insights. The analytics section automatically generates:

A grade distribution chart showing how many A’s, B’s, C’s, D’s, and F’s you’re earning across subjects
A subject-by-subject breakdown with visual progress bars so you can spot weak areas at a glance

These visuals update in real time as you change numbers in the grade table — no extra steps required.

Saves Automatically & Works Offline

All your grades are saved locally in your browser. Close the page, reopen it tomorrow, and everything is still there. Because the calculator runs completely on your device, it works offline after the first visit. No data ever leaves your computer.

Export & Share Your Grade Report

You can generate a professional-looking grade report in multiple formats:

Download as a PDF (ready for printing)
Print directly from the browser
Export as CSV to open in Excel or Google Sheets
Copy the summary as formatted text to paste into an email or message

Teachers and tutors love this feature for sharing progress reports with students and parents.

Understanding the Math Behind the Scenes

How Letter Grades Are Determined

The default A–F scale uses standard ranges:
90–100% = A, 80–89% = B, 70–79% = C, 60–69% = D, below 60% = F.

GPA scales convert percentages into 4.0 or 5.0 systems commonly used in schools.

Weighted Average Formula

Weighted Average = (Σ (grade × weight)) / Σ weights
Each category contributes based on its assigned importance.

Final Exam Predictor Formula

Target = Current × (1 – W) + Needed × W
Solving for “Needed” gives the required exam score.
