Quick summary

GPA (grade point average) is the credit-weighted average of your course grades on a 0–4.0 scale. Multiply each course's grade points (A = 4.0, B+ = 3.3, B = 3.0, and so on) by its credits, add the results, and divide by total credits. For example, an A in a 3-credit course and a B+ in a 4-credit course give 25.2 ÷ 7 = 3.60.

How to use this calculator

  1. Click Add Course to create a row for each class you want to include.
  2. Type a Course Name (optional — it only labels the row in the breakdown).
  3. Enter the Credits for the course; each new row starts at 3, and you can use half credits such as 1.5.
  4. Pick the letter Grade from the menu — each option shows its grade points, such as B+ (3.3).
  5. Repeat for every course, using the trash icon to remove a row you added by mistake.
  6. Read your Cumulative GPA (with its letter badge), Total Credits, and Grade Points, then check the Course Breakdown to see how many points each course contributed.

GPA Formulas & Grade Scale

Weighted GPA

GPA=∑(Grade Points×Credits)∑CreditsGPA = \frac{\sum (\text{Grade Points} \times \text{Credits})}{\sum \text{Credits}}
Grade Points
Numeric value of letter grade (A=4.0, B=3.0, etc.)
Credits
Credit hours for the course

Worked example

Chemistry (3cr, A) + Math (4cr, B+)

Given
chemistry = 3 × 4.0 = 12.0
math = 4 × 3.3 = 13.2
Calculation
GPA=(12.0+13.2)/(3+4)GPA = (12.0 + 13.2) / (3 + 4)
Result
= 25.2 / 7 = 3.60

Standard 4.0 Grade Scale

Worked example

Convert letter grade to points

Given
grade = B+

Result
3 credit course = 9.9 grade points

Frequently asked questions

How is GPA calculated?

GPA is total grade points divided by total credits. For each course, multiply the grade's point value by the course credits, add those products, and divide by the sum of credits. For example, English (3 credits, A = 4.0 → 12 points) plus Math (4 credits, B = 3.0 → 12 points) gives 24 ÷ 7 = 3.43.

How do I calculate my cumulative GPA?

Enter every graded course from all of your terms, each with its credits and grade, and the calculator returns the credit-weighted average across all of them. That is your cumulative GPA on this scale. Leave out pass/fail and other courses your school does not count toward GPA, and use your school's own grade-point values if they differ.

Why do credit hours change my GPA?

Each grade is weighted by its course's credits, so bigger courses move your GPA more. An A in a 1-credit course plus a C in a 4-credit course gives (4.0 × 1 + 2.0 × 4) ÷ 5 = 2.40, not the simple average of 3.0. Improving a grade in a high-credit course has the largest effect.

Does an A+ count as more than an A?

No — on the standard 4.0 scale this calculator uses, A+ and A are both 4.0 grade points. Some schools use a modified scale where an A+ is worth 4.3, and others do not award A+ at all. If your school gives A+ extra points, your official GPA may be slightly higher than the result here.

Is this a weighted or unweighted GPA?

It is unweighted in the high-school sense: every grade uses the standard 4.0 scale, with no extra points for honors, AP, or IB classes. It is weighted only by credit hours. If your school adds a bonus (such as 0.5 or 1.0) for advanced courses, its weighted GPA will be higher than this result.

What letter grade is my GPA?

The badge under your GPA converts it to the nearest letter on the same 4.0 scale. In this calculator, 3.85 and above shows as A, 3.50–3.84 as A−, 3.15–3.49 as B+, 2.85–3.14 as B, and so on down to F at 0. A 3.60 GPA, for example, displays as A−.

What GPA do I need for honors?

It depends on your school — there is no universal cutoff. Colleges set their own GPA thresholds for Latin honors (cum laude, magna cum laude, summa cum laude) and dean's lists, and some award honors by class rank instead. Graduate programs and scholarships also publish their own minimums, so check the specific requirement before planning around a number.

GPA
Grade Point Average — a weighted average of all course grades, typically on a 0–4.0 scale.
Credit Hours
The number of academic credits a course is worth, used as the weight in GPA calculation.
Grade Points
