Grade Calculator

Calculate weighted grades, plan your final grade, estimate your exam score, and calculate your GPA.

Weighted Grade Calculator

Enter your assignment grades and their course weights. Your results update automatically as you make changes.

Regular assignment weight: 0.00% / 100%

Enter valid assignment grades and weights to calculate your result.

Extra credit counts as additional course points (weight × grade). It is divided by the completed weight like your other grades and does not increase the regular course-weight total.

Grading Scale

Select a preset or customize the grades. Enter the lowest percentage for each grade and the maximum is filled in automatically.

How the Grade Calculator Works

Use this free grade calculator to calculate weighted grades, plan your final course grade, estimate the exam score you need, and calculate your GPA. Each calculator uses the information you enter to provide an academic grade estimate.

1. Weighted Grade Calculator

A weighted grade calculator determines your current course grade based on the percentage weight and score of each assignment. Assignments with higher weights have a greater effect on your overall result.

Weighted Grade Formula

Current Weighted Grade = Total Weighted Points / Total Completed Assignment Weight × 100

Example

Suppose you score 80% on homework worth 30% and 90% on an exam worth 40%. Your weighted points are 24 and 36, respectively. Your current weighted grade is:

Weighted Points = (80 × 0.30) + (90 × 0.40)

Weighted Points = 24 + 36 = 60

Current Grade = 60 / 70 × 100 = 85.71%

You can also add extra-credit assignments. Extra credit counts as additional course points (its weight × its grade). Like your other grades, those points are divided by the weight of the coursework you have completed, and they do not increase the regular course-weight total.

For example, suppose you scored 90% on assignments worth 50% of the course and earned 100% on a bonus worth 5%. Your points are (90 × 0.50) + (100 × 0.05) = 50, out of 50 completed, so your current grade is 50 / 50 × 100 = 100%. If all of your coursework were complete, the same bonus would add exactly 5 points to your final grade.

2. Final Grade Planner

The final grade planner calculates the average you need across all remaining coursework to reach your target course grade. It considers your current grade and the percentage of coursework already completed.

Required Remaining Grade Formula

Required Grade = (Target Grade − Current Grade × Completed Weight) / Remaining Weight

Example

Suppose your current grade is 82%, you have completed 50% of your coursework, and your target is 90%. You need an average of 98% across the remaining coursework to reach your target grade.

3. Final Exam Calculator

The final exam calculator determines the score you need on your final exam to achieve your desired overall course grade. Enter your current grade, target grade, and final exam weight.

Final Exam Formula

Required Exam Grade = (Target Grade − Current Grade × (1 − Exam Weight)) / Exam Weight

Example

Suppose your current grade is 85%, your target is 90%, and your final exam is worth 30% of the course grade. You need approximately 101.67% on the final exam to reach your target.

4. GPA Calculator

The GPA calculator estimates your Grade Point Average using the credits and letter grades of your courses. Courses with more credit hours have a greater influence on your overall GPA.

GPA Formula

GPA = Sum of (Course Credits × Grade Points) / Total Course Credits

Example

Suppose you take two courses. Mathematics has 3 credits with a 4.0 grade point, while Science has 4 credits with a 3.0 grade point.

Mathematics: 3 × 4.0 = 12

Science: 4 × 3.0 = 12

Total Grade Points = 24

GPA = 24 / 7 = 3.43

Understanding the Grading Scale

Different schools and universities use different grading systems. Some use a standard letter-grade scale, while others include plus and minus grades such as A-, B+, and C-. The grading scale settings let you customize letter grades, minimum percentages, and GPA values for the Weighted Grade and GPA calculators.

For each grade you enter the lowest percentage that earns it. The maximum is filled in automatically from the next grade up, so the ranges can never overlap or leave gaps. For example, if A starts at 89.5, then B automatically ends at 89.49.

Percentages are rounded to two decimal places before the letter grade is chosen, and the rounded value is the one shown. A result of 89.996% is displayed as 90.00% and counts as 90%. If your school does not round up, check the exact percentage before relying on the letter grade.

Always check your institution's official grading policy before using calculated results for academic decisions.

Frequently Asked Questions

Is this grade calculator free?

Yes. All four calculator features are free to use. You can also customize the grading scale used by the Weighted Grade and GPA calculators.

Can I calculate my final grade without taking the exam?

Yes. Enter your current grade, target grade, and exam weight to estimate the score required on your final exam.

How is weighted GPA different from a regular GPA?

A regular GPA generally uses the grade points assigned to each course. A weighted GPA may include additional points for advanced courses, depending on the institution. This calculator estimates GPA using the grading scale and course grade points you provide.

Can I use a custom grading scale?

Yes. You can edit letter grades, minimum percentages, and GPA values in the grading scale settings. The custom scale must pass validation before it can be used in the applicable calculators.

Does the calculator save my grades?

Your calculator entries are handled in your browser and are not saved to a personal account by this tool. Refreshing the page resets the calculator inputs.

How does the calculator round my grade?

Results are rounded to two decimal places, and the letter grade is based on that rounded number. For example, 59.996% is shown as 60.00% and receives a D-. Some schools round differently, so use the exact percentage if a letter boundary matters.

How is extra credit counted?

Tick "Extra credit" on an assignment. Its weight and grade are added as bonus course points and divided by your completed weight. Your instructor may count extra credit differently, so confirm the policy in your syllabus.

Are the calculated results official?

No. Results are estimates based on the values and grading scale you enter. Your school's official calculation may use different rounding rules, extra credit policies, or course requirements.

Important Note

This grade calculator is intended for educational and estimation purposes. Always refer to your school or university for official grades, GPA calculations, and academic requirements.
