About Us

Grade Calculator is a small set of free calculators built for one moment every student knows: staring at a grade portal and wondering what does this actually mean — and what do I need next? We turn weighted percentages, points, letter grades and GPA into clear answers, instantly.

What you can do here

• Grade Calculator — your current weighted or points-based course grade, with a “what do I need on my final” goal box.
• Final Grade Calculator — the exact final exam score needed for the grade you want.
• GPA Calculator and High School GPA Calculator — term and cumulative GPA, weighted and unweighted.
• Grade Percentage Calculator, Grade Curve Calculator and the grading scale chart for conversions and teachers.
• The blog — plain-language guides that show the maths behind every tool.

How the tools work

Every calculation runs entirely in your browser, on your device. Nothing you type is uploaded, stored or tracked — close the tab and it is gone. The maths follows the standard US grading scale (A = 93%+ and 4.0 points, down to F below 60%), and every page explains its formula with a worked example so you can check the result by hand.

Accuracy, honestly stated

Schools set their own scales and rounding rules, so treat results here as a very close guide rather than an official record. If a result and your school disagree, your school's handbook wins — and if you spot a boundary we have wrong, please tell us so we can fix it.
