You can choose the calculate semester grade mode when you know your first quarter grade, second quarter grade, final exam grade, and each weight. You can also choose the required final exam grade mode when you want to answer what grade do I need on my final to reach a target semester grade.

Semester Grade = (First Quarter Grade x First Quarter Weight / 100) + (Second Quarter Grade x Second Quarter Weight / 100) + (Final Exam Grade x Final Exam Weight / 100). This is an estimate; official grade scales and rounding rules vary by school.
How to Use This Semester Grade Calculator
- Choose Calculate semester grade or What grade do I need on my final.
- Enter the first quarter grade, first quarter weight, second quarter grade, and second quarter weight.
- Enter either the final exam grade or the target semester grade, depending on the mode.
- Enter the final exam weight, confirm that all weights equal 100%, then review the percentage and estimated letter grade.
Semester Grade Calculator Formula
To calculate semester grade, use: Semester Grade = (First Quarter Grade x First Quarter Weight / 100) + (Second Quarter Grade x Second Quarter Weight / 100) + (Final Exam Grade x Final Exam Weight / 100).
To answer what grade do I need on my final, use: Required Final Exam Grade = (Target Semester Grade - Current Weighted Grade) / (Final Exam Weight / 100). Current weighted grade is the first quarter contribution plus the second quarter contribution.
Semester Grade Calculation Example
Suppose your first quarter grade is 84% with a 40% weight, your second quarter grade is 88% with a 40% weight, and your final exam grade is 90% with a 20% weight. The semester grade is 33.6 + 35.2 + 18.0, which equals 86.8%.
If your target semester grade is 90% instead, the required final exam mode subtracts your current weighted grade from the target and divides by the final exam weight as a decimal. The result shows the final exam score needed, but every school can define grade bands and rounding rules differently.

Why Students Use a Semester Grade Calculator
Students use a semester grade calculator online when they need a clear view of how quarter grades, assignments, projects, and final exam scores combine. It is especially helpful before finals because you can see whether a final exam has enough weight to change your final semester grade or whether coursework is the better place to improve.
This tool is not an official transcript calculator. It gives a planning estimate from the numbers you enter, so always compare the output with your course policy.
Common mistakes to avoid
- Using quarter or final exam weights from memory instead of checking the syllabus.
- Entering a points score as a percentage without converting it first.
- Trying to calculate a result when the first quarter, second quarter, and final exam weights do not total 100%.
- Treating the estimated letter grade as official when your institution uses a different scale.

Semester Grade Calculator FAQs
What is a semester grade calculator?
A semester grade calculator estimates your final semester grade by combining first quarter grade, second quarter grade, final exam grade, and the weight assigned to each component.
How do I calculate my semester grade?
Multiply each grade percentage by its weight divided by 100, then add the weighted contributions together. If the weights add up to 100%, the total is your estimated semester grade.
What grade do I need on my final?
Use the required final exam mode. Enter both quarter grades, their weights, the final exam weight, and your target semester grade. The calculator applies the required final exam grade formula and shows the score you need.
What if my total weight is less than 100%?
A total weight below 100% usually means a grading component is missing or not yet included. Check your syllabus and add the remaining assessments before relying on the result.
Can this calculator predict my final course grade?
It can estimate your final course grade from the values you enter, but it cannot replace your teacher, professor, learning platform, or official grading policy.
Are grading scales the same in every university?
No. Letter-grade and pass/fail scales vary by school, college, university, and country, so use the percentage result with your institution's grading policy.
