Free Grade Calculator for Students: Weighted & Final Grade Planner

This free online Grade Calculator helps students calculate weighted course grades, assignment averages and required final exam scores. Enter percentages, GPA values or letter grades like A, B+ or C- to instantly see your current grade and plan what you need on future assignments or finals.

Quick answer: a weighted grade is the sum of each grade multiplied by its weight, divided by the total weight. A 90 worth 20% and an 80 worth 80% gives an 82 overall. To find what you need on a final exam, use the Final Exam Planner tab.

What Are Grades?

Grades are scores used by schools, colleges and universities to measure academic performance. They can be shown as percentages (85%), letter grades (A, B+, C-), GPA values (3.5) or weighted averages based on assignments, quizzes, projects and exams. This calculator converts and combines these formats so you can see where you stand.

How to Calculate a Weighted Grade

Students often use grade calculators to track homework scores, estimate semester performance and prepare for final exams. The weighted system gives more importance to major exams and projects than to smaller homework tasks. Multiply each grade by its weight, add the results, and divide by the total weight.

Weighted gradeWeighted grade = Σ (grade × weight) ÷ Σ weights

For example, homework at 90% worth 5%, a project at 85% (B) worth 20% and a midterm at 88% worth 20% gives (90 × 5 + 85 × 20 + 88 × 20) ÷ 45 = 86.9%, which is a B.

What Grade Do I Need on My Final Exam?

The Final Exam Planner shows the minimum score you need on your final to reach a target course grade. The formula uses your current grade and the weight of the final exam.

Required final exam gradeRequired grade = (target − current × (1 − exam weight)) ÷ exam weight

With a current grade of 88%, a target of 90% and a final worth 30%, you need (90 − 88 × 0.7) ÷ 0.3 = 94.7% on the final. If the result is above 100%, the target is not reachable on the exam alone. You can also use the planning box on the first tab to work out what you need on all of your remaining work.

Letter Grades, Percentages and GPA Values

You can mix formats in the same list. Letters and GPA values are converted to a typical percentage, shown in the last column. Your school may use a different scale, so for exact results enter the percentage from your syllabus when you can. Numbers from 0 to 4.3 are read as GPA points, so add a % sign for a low percentage.

Frequently Asked Questions
Common questions about the Grade Calculator.
What is a weighted grade calculator?
A weighted grade calculator works out your overall course grade by multiplying each assignment or exam score by its weight percentage and adding the results. Heavier assignments, like exams and projects, count for more than smaller tasks like homework.
How do I calculate my final course grade?
Add each assignment, its grade and its weight, then press Calculate Current Grade. The calculator divides the sum of grade × weight by the total weight. For example, a 90 worth 20% and an 80 worth 80% gives (90 × 20 + 80 × 80) ÷ 100 = 82.
What grade do I need on my final exam?
Use the Final Exam Planner. Enter your current grade, your target grade and the weight of the final exam. The formula is (target − current × (1 − exam weight)) ÷ exam weight. With a current 88, a target of 90 and a 30% final, you need about 94.7%.
Does this calculator support letter grades and GPA values?
Yes. You can enter letters such as A, B+ or C-, percentages such as 88%, or GPA-style numbers such as 3.7. Letters and GPA values are converted to approximate percentages using the chart on this page. Numbers from 0 to 4.3 are read as GPA points, so add a % sign to enter a low percentage.
How accurate is the grade calculator?
It uses the standard weighted average formula used by schools and universities. Results depend on your institution's grading scale and how it rounds, so treat letter grades as estimates and check your syllabus for the official policy.
Is this grade calculator free to use?
Yes. It is completely free, needs no sign-up and works on desktop, tablet and mobile. You can add as many assignments, quizzes, projects and exams as you need.
