Calculate your semester grade using quarterly grades, final exam scores, and customizable weights with step-by-step solutions.
Enter your grades and weights, then click Calculate to see your semester grade
A semester grade calculator is an essential academic tool that helps students calculate their final semester grade based on multiple grading periods such as quarters, midterms, and final exams. This calculator uses a weighted average formula where each component (quarters, exams, projects) is assigned a specific percentage weight that determines its contribution to the overall semester grade.
Unlike a simple average, a semester grade calculator accounts for the varying importance of different assessment periods. For example, final exams might count for 20% of your grade while each quarter counts for 40%. This weighted approach provides a more accurate reflection of your academic performance throughout the semester.
Our free semester grade calculator supports unlimited grading periods, automatically normalizes weights if they don't sum to 100%, and provides detailed step-by-step solutions showing exactly how your semester grade is calculated. Whether you're in high school, college, or graduate school, this tool helps you track your academic progress and plan for success.
Input the percentage grades you've earned for each grading period (e.g., Quarter 1: 85%, Quarter 2: 92%). Leave blank if you haven't completed a period yet.
Assign the weight (importance) of each grading period. Common distributions are 40%-40%-20% (two quarters + final exam) or 45%-45%-10% for different grading systems.
Click "Add Another Period" to include additional grading components like projects, participation, or midterm exams that contribute to your semester grade.
Click the "Calculate" button to see your weighted semester grade, letter grade, detailed breakdown, and step-by-step solution.
Examine the weighted breakdown table to understand how each period contributes to your final grade. Use this insight to identify areas for improvement.
The semester grade calculator uses a weighted average formula to calculate your final grade. Here's the mathematical representation:
General Formula:
Where:
• G₁, G₂, ..., Gₙ = Individual period grades (as percentages)
• W₁, W₂, ..., Wₙ = Weights for each period (as decimals, e.g., 0.40 for 40%)
• n = Number of grading periods
Given:
Solution:
Step 1: Convert weights to decimals
W₁ = 40% = 0.40
W₂ = 40% = 0.40
W₃ = 20% = 0.20
Step 2: Multiply each grade by its weight
Q1 Contribution = 85 × 0.40 = 34.00
Q2 Contribution = 92 × 0.40 = 36.80
Final Contribution = 78 × 0.20 = 15.60
Step 3: Add all contributions
Semester Grade = 34.00 + 36.80 + 15.60
Semester Grade = 86.40%
Most common in high schools and undergraduate courses. Emphasizes continuous performance over two quarters with a final exam.
Used in trimester systems where continuous assessment is prioritized over final exams.
Distributes weight equally across all assessment periods, common in college courses.
Includes significant project work alongside traditional assessments, common in STEM courses.
Our calculator uses the standard 4.0 GPA letter grade scale used by most high schools and colleges in the United States:

| A+ | 97-100% | 4.0 | Outstanding |
| A | 93-96% | 4.0 | Excellent |
| A- | 90-92% | 3.7 | Excellent |
| B+ | 87-89% | 3.3 | Very Good |
| B | 83-86% | 3.0 | Good |
| B- | 80-82% | 2.7 | Good |
| C+ | 77-79% | 2.3 | Satisfactory |
| C | 73-76% | 2.0 | Satisfactory |
| C- | 70-72% | 1.7 | Satisfactory |
| D+ | 67-69% | 1.3 | Below Average |
| D | 63-66% | 1.0 | Below Average |
| D- | 60-62% | 0.7 | Poor |
| F | 0-59% | 0.0 | Failing |
Students use semester grade calculators to track their progress throughout the term, identify which courses need more attention, and calculate what scores they need on final exams to achieve their target grades. This helps in prioritizing study time effectively.
College students maintain their cumulative GPA by calculating semester grades in advance. This is crucial for maintaining scholarships, academic standing, honor roll eligibility, and admission to competitive programs or graduate schools.
Parents and teachers use semester grade calculators during conferences to explain how different assessment components contribute to final grades, helping families understand academic performance and set realistic improvement goals.
Students deciding whether to withdraw from a challenging course use semester calculators to determine if passing is still achievable. This helps avoid unnecessary W grades on transcripts while making informed academic decisions.
Students on academic scholarships that require minimum GPA thresholds use semester calculators to ensure they maintain eligibility. Early calculation allows time to improve grades before the semester ends.
Seniors calculate semester grades to ensure they meet graduation requirements and maintain the GPA needed for honors distinctions like cum laude, magna cum laude, or summa cum laude at commencement.
Use the calculator to work backwards - if you have a target semester grade, calculate what score you need on your final exam or remaining assignments to achieve it.
Prioritize studying for assessments with higher weights. A 5-point improvement on a 40% weighted component has more impact than the same improvement on a 10% component.
Recalculate your semester grade after each major assessment. Early detection of grade drops gives you more time to implement improvements.
Even small extra credit points can significantly impact your semester grade. Always complete optional assignments when your grade is borderline.
If you're struggling, discuss your semester grade calculation with your teacher. They may offer study resources, tutoring, or alternative assessment options.
Based on your required scores, allocate study time proportionally to each subject. Courses where you need higher improvement should receive more attention.
To calculate a semester grade with quarters and finals, multiply each grade by its weight (as a decimal), then sum all the weighted values. For example, with Q1=85% (40%), Q2=90% (40%), and Final=80% (20%): (85×0.40) + (90×0.40) + (80×0.20) = 34 + 36 + 16 = 86% semester grade.
Our calculator automatically normalizes your grade when weights don't sum to 100%. It divides the weighted sum by the total weight, then multiplies by 100 to give you an accurate percentage. For example, if weights total 80%, the calculator adjusts accordingly.
Yes! Simply leave the grade field blank for any incomplete periods. The calculator will compute your semester grade based only on completed work. This is useful for predicting your current standing or calculating what you need on remaining assessments.
A semester grade is the percentage or letter grade you receive in a single course (e.g., 86% or B+). Semester GPA is the average of all your course grades for that semester, calculated by converting letter grades to GPA points (e.g., A=4.0, B=3.0) and averaging them with credit hour weighting.
Check your course syllabus, which typically lists the weight distribution for quarters, exams, projects, and participation. You can also ask your teacher or check the online gradebook, which often displays percentage weights. Common distributions are 40-40-20 or 45-45-10 for two-quarter systems.
Absolutely! Click "Add Another Period" to include additional grading periods for trimester, quarter, or any custom grading system. The calculator supports unlimited periods with flexible weight distributions to accommodate any academic schedule.
Enter your current quarter grades and their weights, then set different final exam scores until your semester grade reaches your target (typically 90% or 93% for an A). Our step-by-step solution will show you the exact calculation. For precise "what-if" scenarios, try different values systematically.
Yes, this semester grade calculator works for all educational levels—high school, college, graduate school, and professional programs. The weighted average formula is universal. Just ensure you input the correct weights as specified in your course syllabus.
Each semester grade (converted to GPA points) contributes to your cumulative GPA based on the course's credit hours. Higher credit courses have more impact. For example, a 4-credit course affects your GPA more than a 1-credit course. Calculate individual semester grades first, then use a cumulative GPA calculator.
