About the GPA Calculator
The GPA Calculator uses the standard US 4.0 grading scale to calculate your cumulative Grade Point Average across multiple subjects. Enter each subject's letter grade and credit hours, then press Calculate GPA to see your result, total credits earned, and academic standing classification.
How GPA Is Calculated
Each letter grade is converted to a grade point value (A = 4.0, B = 3.0, etc.). Those grade points are multiplied by the course's credit hours to produce weighted grade points. Your GPA is the sum of all weighted grade points divided by the total number of credit hours:
GPA = Σ (Grade Points × Credits) ÷ Σ Credits
For example, if you earn a B+ (3.3) in a 4-credit course and an A (4.0) in a 3-credit course, your GPA is (3.3 × 4 + 4.0 × 3) ÷ (4 + 3) = (13.2 + 12.0) ÷ 7 = 3.60.
The 4.0 GPA Scale
The table below shows the letter grade to grade point conversion used by this calculator, based on the most widely adopted US university standard:
| Letter Grade | Grade Points | Descriptor |
|---|---|---|
| A+ / A | 4.0 | Excellent |
| A− | 3.7 | Excellent |
| B+ | 3.3 | Above Average |
| B | 3.0 | Above Average |
| B− | 2.7 | Above Average |
| C+ | 2.3 | Average |
| C | 2.0 | Average |
| C− | 1.7 | Average |
| D+ | 1.3 | Below Average |
| D | 1.0 | Below Average |
| D− | 0.7 | Below Average |
| F | 0.0 | Failing |
Academic Standing Classifications
The following thresholds reflect common US university standards, though exact requirements vary by institution:
- Summa Cum Laude (3.90–4.00): Highest academic distinction, typically awarded at graduation.
- Magna Cum Laude (3.70–3.89): High distinction, indicating consistently exceptional performance.
- Cum Laude (3.50–3.69): Academic distinction recognising strong overall performance.
- Good Standing / Dean's List (3.00–3.49): Solid academic performance, often required for scholarships and competitive programmes.
- Satisfactory (2.00–2.99): Meeting minimum graduation requirements for most institutions.
- Academic Probation Risk (below 2.00): Below the minimum standard — many universities place students on academic probation below 2.0.
Frequently Asked Questions
How is GPA calculated? GPA is calculated by multiplying each subject's grade points by its credit hours, summing those totals, then dividing by the total credit hours. For example, an A (4.0) in a 3-credit course and a B (3.0) in a 3-credit course gives (12 + 9) ÷ 6 = 3.50 GPA.
What is the GPA scale used in this calculator? This calculator uses the standard US 4.0 scale: A+/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. Some institutions assign A+ a value of 4.3 — check your school's policy.
What GPA do I need for Dean's List or honours? Common thresholds are 3.9+ for Summa Cum Laude, 3.7+ for Magna Cum Laude, 3.5+ for Cum Laude, and 3.0+ for Good Standing or Dean's List eligibility. Requirements vary by institution.
Does the subject name affect GPA? No. Subject names are optional labels for your own reference. Only the grade points and credit hours are used in the calculation.
Can I add more than 4 subjects? Yes — click the '+ Add Subject' button to add as many rows as needed. Use the × button on any row to remove it.
