Weighted grades, final planning, and points

Grade Calculator

Calculate your current course grade from weighted assignments, quizzes, projects, exams, letter grades, percentages, or points, then plan the score you need on a final exam.

Weighted course grade

Enter each assessment score and how much it counts toward the course.

Letter grade scale

Adjust percentage boundaries; this active scale controls letter inputs, result letters, and GPA-point labels.

How it works

How grade calculation works

Use this section to understand the basic weighted-grade formula and how a partial course average is calculated before all assignments are entered.

Formula

How to calculate a grade

A weighted grade calculator takes each assessment score, converts it to a percentage, multiplies it by the assessment weight, then divides the total by the weight you entered. Use the row weight from your syllabus or gradebook, such as 20 for a project worth 20% of the course.

weighted grade = sum(score x weight) / sum(weight)

Example

Example weighted grade

If Homework 1 is 90% at 5%, Project is B at 20%, and the Midterm exam is 88% at 20%, GradeCal reports a percentage average of 86% and a GPA-style average grade of B+ (3.21), based on the 45% total weight entered so far. The weight meter tells you that this is not the full course yet.

Planning

Final grade and scale settings

Use final grade mode when you need a target score, and adjust letter cutoffs only when your class uses a different grading scale.

Final planning

Plan the final exam score you need

Final grade mode estimates the final exam score required to reach your target course grade. If the required score is above 100%, GradeCal marks the target as not reachable with a perfect final.

required final = (target - current x (1 - final weight)) / final weight

Letter scales

Adjust the scale for your class

Letter grades vary by school and instructor. GradeCal starts with a common US-style plus/minus scale, but you can edit the minimum percentage for each letter grade before calculating.

Use cases

When to use this grade calculator

GradeCal is designed for course averages with multiple items, especially when a gradebook uses weights or when raw and weighted averages do not match.

Course vs test

Use this page for course grades

GradeCal is built for a whole class grade: homework, projects, quizzes, exams, weights, letter inputs, and final grade planning. A test grade calculator or easy grader is different because it starts from one exam, such as 47 correct out of 50 questions, and turns that into a single test score.

Check your inputs

Why weighted and raw averages can differ

A raw average treats every score equally. A weighted average gives larger assignments more influence. GradeCal shows both when they differ, so you can see whether a heavily weighted exam or project is pulling the course grade up or down.

Formats

Grade formats and grading periods

Match each row to the format your gradebook uses, then treat the result as a planning estimate for the current semester, quarter, or class period.

Formats

Choose the grade format that matches your gradebook

Use percentages for scores such as 92%, letters for scores such as B+, and points for scores such as 45/50. Points are converted to a percentage before weighting, while letter grades use the active scale shown in the calculator.

Grading periods

Semester, quarter, and high school grade checks

GradeCal can work for a semester, quarter, or high school class when you know the scores and weights for that period. If your school uses special policies, use this calculator as a planning aid and confirm the official rules in your syllabus or gradebook.

FAQ

Grade calculator questions

What is a grade calculator?

A grade calculator estimates your course grade from assignment, quiz, project, exam, and final scores. GradeCal supports weighted rows, percentages, letter grades, points, and final grade planning.

How do I calculate a weighted grade?

Multiply each score by its weight, add those weighted scores together, and divide by the total weight you entered.

What if my weights do not add up to 100?

GradeCal still calculates the weighted average of the rows you entered, then shows whether the total weight is below or above 100.

Can I use points instead of percentages?

Yes. Enter a score such as 45/50 and GradeCal converts it to a percentage before applying the row weight. This is different from GPA points, which are shown in the result for letter-grade comparison.

Can I calculate a final grade with letter grades?

Yes. In Final Grade mode, switch the grade type to Letter. GradeCal converts the current and target letters through the active letter scale, which you can edit for your class.

How does the final grade calculator work?

It uses your current grade, target grade, and final exam weight to estimate the final exam score required to reach the target.

Can I use this for semester or quarter grades?

Yes, if your semester or quarter grade is based on weighted coursework. Enter the scores and weights that count for that grading period, then check whether the entered weights represent the full period.

Can high school students use this grade calculator?

Yes. High school students can use GradeCal for class grades when they know their scores and weights. School grading policies vary, so use your teacher's syllabus or gradebook as the source for weights and letter cutoffs.

Why is my weighted grade different from my raw average?

A raw average treats every score equally. A weighted grade gives more influence to rows with larger weights, so a major exam or project can move the course grade more than a small homework score.

Is this the same as a test grade calculator?

No. This page is mainly for course grades and final grade planning. A test grade calculator usually converts questions missed or points earned into one exam score.

Are letter grade scales the same at every school?

No. Schools and instructors can use different cutoffs. GradeCal starts with a common US-style scale, and you can edit the cutoffs for your class.
