What is an Online Grade Calculator?

An online grade calculator is a free digital tool designed to help students accurately compute their academic grades without manual calculations. Whether you're calculating your final course grade, cumulative GPA, or weighted assignment grades, our calculator provides instant, accurate results tailored to your specific grading system.

Our comprehensive grade calculator offers three powerful calculation modes in one convenient platform:

  • Final Grade Calculator: Determine your overall course grade based on your current grade and final exam performance. Instantly see what score you need on your final exam to achieve your target grade.
  • GPA Calculator: Calculate your Grade Point Average across multiple courses with support for both 4.0 and 5.0 scales. Perfect for high school and college students tracking their cumulative academic performance.
  • Weighted Grade Calculator: Compute your grade when different assignment categories (homework, quizzes, tests, finals) carry different weights in your final grade calculation.

Students use grade calculators for various academic planning purposes: predicting final grades before receiving exam scores, determining minimum required scores on upcoming exams, tracking GPA for college applications, and understanding how individual assignments impact overall course performance. Our calculator automatically saves your calculation history, allowing you to track your academic progress over time.

How Does the Online Grade Calculator Work?

Our online grade calculator uses proven mathematical formulas to compute accurate grade calculations instantly. The calculator operates differently depending on which mode you're using, but all modes share the same principle: weighted averages based on the relative importance of each grade component.

Final Grade Calculator Mode

When calculating your final course grade, the calculator uses a weighted average formula. You provide three inputs:

  1. Current Grade: Your grade percentage before the final exam (for example, 85%)
  2. Final Exam Weight: The percentage your final exam counts toward your total grade (commonly 20-40%)
  3. Final Exam Grade: Your actual or expected score on the final exam

The calculator multiplies your current grade by its weight (100% minus the final exam weight), adds this to your final exam grade multiplied by the final exam weight, then divides by 100. The result is your overall course grade. The calculator also converts this numerical grade to a letter grade (A+, A, A-, etc.) using standard US grading scales.

Additionally, you can enter a target course grade, and the calculator will instantly show you exactly what score you need on your final exam to achieve that target. This feature is invaluable for academic planning and goal setting.

GPA Calculator Mode

The GPA calculator converts letter grades from multiple courses into a Grade Point Average. Each letter grade corresponds to a point value (A = 4.0, B = 3.0, C = 2.0, etc. on the 4.0 scale). The calculator multiplies each course's grade point value by its credit hours, sums all these weighted points, and divides by the total credit hours. This gives you an accurate cumulative GPA.

Our GPA calculator supports both 4.0 and 5.0 scales, accommodating different institutional grading systems and weighted/honors courses. You can add unlimited courses, making it perfect for calculating semester GPA or cumulative GPA across multiple terms.

Weighted Grade Calculator Mode

Many courses use weighted grading systems where different assignment categories contribute different percentages to your final grade. The weighted grade calculator lets you input multiple categories (homework, quizzes, tests, final exam, participation, etc.), assign each a weight percentage, and enter your grade for each category.

The calculator multiplies each category grade by its weight (as a decimal), sums all weighted grades, and displays your overall weighted grade. The calculator validates that your weights add up to 100% and alerts you if they don't, ensuring calculation accuracy.

Real-Time Calculations and History

All calculations update in real-time as you type, providing instant feedback without requiring you to click a "Calculate" button. Your calculations are automatically saved to your browser's local storage, creating a personal grade history you can review, export, or clear at any time. This history feature helps you track grade trends and academic progress throughout the semester.

How is Your Final Grade Calculated?

Understanding the mathematics behind grade calculations empowers you to predict and plan your academic performance. Let's break down the exact formulas used in each calculation mode.

Final Course Grade Formula

Final Grade = (Current Grade × Current Weight) + (Final Exam Grade × Final Exam Weight)

Where Current Weight = 100% - Final Exam Weight

Example Calculation:

  • Current Grade: 85%
  • Final Exam Weight: 25%
  • Final Exam Grade: 90%
  • Current Weight: 100% - 25% = 75%

Final Grade = (85 × 0.75) + (90 × 0.25) = 63.75 + 22.5 = 86.25%

Required Final Exam Score Formula

To calculate what you need on your final exam to achieve a target grade, we rearrange the formula:

Required Final Score = (Target Grade - Current Grade × Current Weight) / Final Exam Weight

Example Calculation:

  • Current Grade: 82%
  • Final Exam Weight: 30%
  • Target Course Grade: 88%
  • Current Weight: 70%

Required Score = (88 - 82 × 0.70) / 0.30 = (88 - 57.4) / 0.30 = 102% (target may not be achievable)

GPA Calculation Formula

GPA = Σ(Grade Points × Credit Hours) / Σ(Credit Hours)

Grade points are assigned based on letter grades: A+ = 4.0, A = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, B- = 2.7, C+ = 2.3, C = 2.0, C- = 1.7, D+ = 1.3, D = 1.0, D- = 0.7, F = 0.0

Letter Grade Conversion Scale

A+ (97-100%)

4.0 GPA

A (93-96%)

4.0 GPA

A- (90-92%)

3.7 GPA

B+ (87-89%)

3.3 GPA

B (83-86%)

3.0 GPA

B- (80-82%)

2.7 GPA

C+ (77-79%)

2.3 GPA

C (73-76%)

2.0 GPA

This standard US grading scale is used by most American high schools and colleges. Some institutions may use slightly different scales, but these are the most common grade boundaries.

Frequently Asked Questions

How do I calculate my final grade?
Multiply your current grade by its weight (100% minus final exam weight), add your final exam grade multiplied by the final exam weight, then divide by 100. Our calculator does this instantly.
What grade do I need on my final exam?
Enter your current grade, final exam weight, and target course grade. The calculator shows exactly what score you need on your final exam to achieve your target.
How much is 70% of my grade?
If your final exam is worth 70% of your grade, it means the final contributes 70 points out of 100 to your total course grade. The remaining 30% comes from your coursework before the final.

Is 75% an A or B?
75% is a C (neither A nor B) in US grading. It falls in the 73-76% C range. A B requires 80%+ and an A requires 90%+.
Is 76% C+?
No. 76% is still a C (73-76% range). C+ begins at 77% and goes up to 79%. So 76% is just one percentage point below C+.
What is 75% on a 4.0 scale?
75% equals 2.0 GPA on a 4.0 scale (C grade). The conversion is: C (73-76%) = 2.0 GPA.
What is 75 out of 100 in uni?

What is a weighted grade?
A weighted grade multiplies each assignment category grade by its percentage weight, then sums them. Example: If homework is 20% and you scored 85%, it contributes 17 points (85 × 0.20) to your final grade.
Is this grade calculator free?
Yes! Completely free with no registration, unlimited calculations, and full access to Final Grade, GPA, and Weighted Grade calculators.
