Calculate your semester GPA or cumulative GPA by entering your course credit hours and letter grades. Works for high school and college on the standard 4.0 scale.
Enter each course, its credit hours, and the letter grade you got (or expect). Add your previous cumulative GPA and credits below if you want a running cumulative GPA instead of just this term.
| Course | Credit hours | Grade | |
|---|---|---|---|
Based on a standard 4.0 scale (A/A+ = 4.0, A- = 3.7, B+ = 3.3, and so on). Some schools cap A+ at 4.3 or use slightly different scales — check your school's official grading policy for the exact figures.

Your GPA (Grade Point Average) is a credit-weighted average of the grade points you earn in each course. For every course, multiply the grade points (based on the letter grade) by the number of credit hours, add those up across all courses, then divide by your total credit hours:
GPA = (Σ grade points × credit hours) ÷ (Σ credit hours)
A course worth more credit hours has a bigger effect on your GPA than a 1-credit course, even with the same letter grade.
This calculator uses the standard 4.0 scale below. Some schools cap A+ at 4.3 instead of 4.0, or don't use +/- grades at all — check your school's official policy if you need an exact match.
| Letter grade | Grade points |
|---|---|
| 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 |
Semester GPA only looks at the courses you enter for the current term. Cumulative GPA combines your new courses with your GPA and credit hours from every previous term. To calculate your cumulative GPA, fill in your previous GPA and previous credit hours above the course table — the calculator will blend them with your current courses automatically.
If your course marks are given as a percentage rather than a letter grade, try the US Letter Grade Calculator to convert your weighted assignment scores into a final letter grade first.
These are commonly cited ranges, not universal rules — every school sets its own thresholds, so treat this as a rough guide only:
| Benchmark | Typical GPA |
|---|---|
| Summa cum laude (graduation honors) | 3.9+ |
| Magna cum laude (graduation honors) | 3.7–3.89 |
| Cum laude (graduation honors) | 3.5–3.69 |
| Dean's List (semester) | 3.5–3.7+ |
| Good academic standing | 2.0+ |
| Academic probation threshold | Below 2.0 |
A single low grade has less impact than it feels like, especially once you have several completed courses — your GPA is an average across all your credit hours, so one course out of many pulls less weight. Use the calculator above with your actual numbers to see the real effect rather than guessing.
Requirements vary by school, but a common range is a 3.5-3.7+ semester GPA with a minimum full-time credit load (often 12+ credits). Check your school's specific policy for the exact cutoff and eligibility rules.
No — your semester GPA only reflects that term's courses, while your cumulative GPA is the running average across every term you've completed. Use the "previous GPA" and "previous credit hours" fields above to blend a new semester into your cumulative total.
Most US colleges set the academic probation threshold around a 2.0 cumulative GPA, though some programs or scholarships require higher minimums. Check your school's academic standing policy for the exact number that applies to you.
