How to Use the Grade Calculator

This comprehensive grade calculator supports multiple calculation types and international grading systems. Whether you're calculating your current grade in a course, determining your GPA, or predicting what score you need on a final exam, this tool provides accurate calculations with detailed breakdowns. The calculator supports various grading scales including the US 4.0 system, UK classifications, European scales, and percentage-based systems. For current grade calculations, simply enter your assignments with their scores, maximum points, and weights. The calculator automatically computes your weighted average and provides category breakdowns. For GPA calculations, input your courses with grades and credit hours, and choose between weighted or unweighted calculations. The grade prediction feature helps you determine exactly what score you need on remaining work to achieve your target grade.

📊 Multi-System Support

The calculator supports major international grading systems and automatically converts between them for easy comparison.

What the Grade Calculator Calculates

The Grade Calculator is a comprehensive academic tool that handles four different types of calculations to meet all your academic needs. For current grade calculations, it computes weighted averages based on assignment scores, maximum points, and category weights, providing detailed breakdowns by assignment type (tests, homework, projects, etc.). The calculator ensures weights total 100% and shows completion status for each assignment. For GPA calculations, it supports both weighted and unweighted systems, factoring in course credits and types (Regular, Honors, AP, IB). The system can calculate cumulative GPA across all courses or semester-specific GPA. Grade prediction functionality determines exactly what score you need on remaining work to achieve your target grade, considering current performance and the weight of future assignments. The calculator also provides international grade conversions, allowing you to see how your grades translate across different educational systems worldwide, from US letter grades to UK classifications to European point systems.

Grade Calculation Examples

Current Grade Example

Academic Scenario

assignments:
Homework (20%): 85/100, Midterm (30%): 78/100, Projects (25%): 92/100, Participation (10%): 95/100
calculationType:current-grade
gradingScale:us-4.0

Calculated Result

84.7% (B)

Weighted average across all completed assignments with category breakdown showing strongest performance in participation and projects.

GPA Calculation Example

Academic Scenario

courses:
Course 1
credits
Course 2
credits
Course 3
credits
Course 4
credits
weighted:true
gradingScale:us-plus-minus

Calculated Result

3.65 GPA (3.89 weighted)

Unweighted GPA based on grade points times credits, with weighted GPA factoring in course difficulty bonuses for AP and Honors classes.

Grade Prediction Example

Academic Scenario

currentGrade:82
targetGrade:88
finalWeight:25
gradingScale:percentage

Calculated Result

96% needed on final work

To raise overall grade from 82% to 88% when final work is worth 25%, you need 96% on remaining assignments - challenging but achievable.

Frequently Asked Questions

Unweighted GPA treats all courses equally on a standard 4.0 scale regardless of difficulty. Weighted GPA adds bonus points for advanced courses: typically +0.5 for Honors courses and +1.0 for AP/IB courses. For example, an A in AP Chemistry might count as 5.0 instead of 4.0 in weighted calculations.

Grade Calculation Methods & Formulas

Understanding the mathematical foundations behind different grade calculations

Formula

Grade ​=​ Σ​(​Score ​×​ Weight​)​ ​/​ Σ​(​Weight​)​

Weighted Average Formula

Grade ​=​ Σ​(​Score ​×​ Weight​)​ ​/​ Σ​(​Weight​)​

GPA Calculation Formula

GPA ​=​ Σ​(​Grade Points ​×​ Credits​)​ ​/​ Σ​(​Credits​)​

Grade Prediction Formula

Required Grade ​=​ ​(​Target ​×​ 100 ​-​ Current ​×​ Current Weight​)​ ​/​ Final Weight

Weighted GPA Formula

Weighted GPA ​=​ Σ​(​​(​Grade Points ​+​ Course Bonus​)​ ​×​ Credits​)​ ​/​ Σ​(​Credits​)​

Scientific Background

Grade calculation methods vary significantly across educational systems worldwide. The US 4.0 GPA system assigns numerical values to letter grades, with A=4.0, B=3.0, etc. Weighted GPA systems add bonus points for advanced courses: typically +0.5 for Honors and +1.0 for AP/IB courses. The UK uses a classification system (First Class, Upper Second, etc.) based on percentage ranges. European systems often use 10-point or 20-point scales. Grade prediction uses linear algebra to determine required performance on remaining work, assuming current performance represents a fixed percentage of the final grade.
