Letter Grades and Calculation Percentages
Use each letter’s Calculation Percentage from the reference table. B uses 84.50%, A− uses 91.00%, and F uses 0.00% across all four GPA scales.

Understand 4.0 Scale GPA and Percentage Rules
This calculator assigns each course a Calculation Percentage based on its letter grade, then combines these percentages using course credits. The total percentage determines your overall letter grade and the corresponding GPA on your selected scale.
Course Credits
GPA credits are the credits attached to courses included in your calculation. A 4-credit course contributes twice as much as a 2-credit course.
Overall Letter and GPA
Apply the letter-grade bands to the credit-weighted percentage, then look up that letter’s GPA. B with 3 credits and A− with 4 credits produce 88.21%, B+, and 3.30 GPA on the 4.0 scale.
Calculation Percentages are fixed by letter: B uses 84.50%, A− uses 91.00%, and F uses 0.00%. These reference values do not recover the original percentage grade from a transcript.
How to Use the 4.0 Scale GPA to Percentage Calculator
Start with the 4.0 Scale
The 4.0 GPA scale is already set for you. It applies to every course and stays fixed in Simulator, so you can start entering grades and credits right away.
Add Grades and Credits
Enter credits and letter grades, then click Calculate Percentage. Each grade maps to a Calculation Percentage. Credits weight the total, which determines your overall letter grade and GPA.
Simulate Grade Changes
Drag the slider from F to A+. Original grades stay gray while simulated grades and percentages appear in green. Credits stay fixed as your total percentage and GPA update.
How Percentage is Calculated on a 4.0 Scale
This calculator assigns each course a Calculation Percentage based on its letter grade, then combines these percentages using course credits. The total percentage determines your overall letter grade and the corresponding GPA on your selected scale. The examples below use the 4.0 GPA scale.
1. Find Each Course’s Calculation Percentage
Course Calculation Percentage = reference table[course letter grade]
Match each course’s letter grade to the Calculation Percentage in the reference table. For example, B uses 84.50%, while A− uses 91.00%. These are fixed calculation values used by this tool, rather than the course’s original percentage grade.
2. Weight Each Percentage by Course Credits
Weighted course percentage = Calculation Percentage × course credits
Multiply each course’s Calculation Percentage by its credits. Courses with more credits contribute more to the total. A 3-credit B contributes 84.50 × 3 = 253.50. A 4-credit A− contributes 91.00 × 4 = 364.00.
3. Calculate the Total Percentage
Total Percentage = Σ (Calculation Percentage × credits) ÷ Σ credits
Add the weighted course percentages, then divide by the total credits. For the two example courses: (253.50 + 364.00) ÷ (3 + 4) ≈ 88.21%. Keep full precision during the calculation and round only the displayed result to two decimal places.
