Course Grade Calculator
See your cumulative course grade from weighted categories, or set any target grade and find out what you need on what's left to reach it.
This course grade calculator works for the entire term as one cumulative total. If your course is split into separate quarters or a midterm/final structure, the Quarter Grade Calculator or Midterm Grade Calculator may match your syllabus more closely.

What Is a Course Grade Calculator?
A course grade calculator combines every graded component of a course — homework, quizzes, midterms, and the final exam — into one cumulative percentage and letter grade, weighted by how much each category is worth. It covers the entire course as a single running total rather than one test, one quiz, or one marking period.
This tool also handles a second, very practical question: once you know your current grade and how much weight is left in the course, the "Goal Grade" tab tells you exactly what score you need on the remainder to hit any target — not just a passing grade, but a specific A, B, or C.
Standard Grading Scale for Course Grades
Once your course percentage is calculated, match it against your school's grading scale. Most U.S. schools use this baseline:
| Percentage | Letter Grade |
|---|---|
| 90–100% | A |
| 80–89% | B |
| 70–79% | C |
| 60–69% | D |
| Below 60% | F |
Example: Setting a Goal Grade
Say your current course grade is 82%, you have 20% of your grade left (the final exam), and you want to finish with a 90% overall. The course grade calculator solves for the score you need on that remaining 20%.
| Current Grade | Remaining Weight | Target | Score Needed |
|---|---|---|---|
| 82% | 20% | 90% (A) | 122.0% (Not possible) |
| 82% | 20% | 85% (B) | 97.0% |
| 88% | 20% | 90% (A) | 98.0% |
| 92% | 20% | 90% (A) | Already secured |
The course grade calculator flags both extremes clearly: when a target is mathematically out of reach, and when it's already locked in regardless of what happens on the remaining work — so you always know exactly where you stand before the final grade posts.
Typical Course Category Weights
Not sure what weight to enter for each category? These are common patterns across different course types — always confirm against your own syllabus first.
| Course Type | Typical Weighting |
|---|---|
| High school course | Homework 15% · Quizzes 20% · Midterm 25% · Final 40% |
| College lecture course | Homework 10% · Midterms 40% · Final Exam 30% · Participation 20% |
| College seminar course | Papers 40% · Participation 30% · Final Project 30% |
These figures are common starting points, not fixed rules — every instructor sets their own breakdown, so treat this table as a rough guide rather than something to enter without checking first. If your syllabus lists a category this table doesn't cover, such as lab work or peer reviews, add it as its own row with whatever weight your instructor assigned — the course grade calculator handles any number of categories, so there's no need to force your syllabus into one of the three patterns above if it genuinely doesn't match.
Course Grade Calculator vs. Every Other Tool on This Site
This is the most general, cumulative version of grade calculation on the site — the whole course, any target grade, not scoped to a single test, quiz, marking period, or pass/fail threshold. Here's how it compares to the more specific tools:
| Tool | Scope |
|---|---|
| Course Grade Calculator | Entire course, any target grade |
| Class Grade Calculator | Entire course, pass/fail focused |
| Quarter Grade Calculator | One marking period |
| Midterm Grade Calculator | Midterm-plus-final structure specifically |
| Semester Grade Calculator | Quarters plus midterm plus final combined |
For background on how weighted category grading works generally, MSU Denver's CTLD resource on weighted grading breaks down the underlying math, and Wikipedia's overview of U.S. academic grading covers how these percentages typically map to letter grades.
Frequently Asked Questions
Multiply your grade in each category by its weight, add the results together, and divide by the total weight. This tool does that automatically once you enter your categories from your syllabus.
Switch to the "Goal Grade" tab, enter your current grade and how much weight is left, then use the "Goal: A" preset or type 90 directly. The calculator solves for the exact score you need on everything remaining.
They're very similar — both cover the whole course as one running total. This course grade calculator adds a general "Goal Grade" mode for any target percentage, while the Class Grade Calculator is built specifically around checking whether you'll pass. Which one to reach for mostly comes down to what question you're actually asking.
If even a perfect score on everything remaining wouldn't reach your target, the calculator shows "Not possible" along with the best final grade you could realistically still achieve given what's left.
Yes — the weighted category math is the same regardless of level. Just enter your own categories, grades, and weights exactly as they appear on your syllabus.
Enter what you do know and leave the rest out for now — your result will reflect only the completed portion of the course. Once your syllabus or instructor confirms the remaining weights, add them in for a complete picture that reflects the entire term.
