The GPA calculator works out your cumulative grade point average on the 4.0 scale used across US and Canadian colleges. Add each course with its letter grade and credit hours, and the calculator weights them correctly to produce your overall GPA. Results update instantly as you add or adjust courses. Students check their GPA at several important moments: before applying to graduate school or professional programs (most require a minimum GPA, typically 3.0 or higher), when applying for merit scholarships, when checking academic standing requirements, or simply tracking whether a strong finals performance can pull a semester GPA back up. This tool is most useful for planning. Enter your completed courses alongside in-progress courses with your expected grades to model what your final GPA will look like at semester end. Trying different grade scenarios takes seconds and helps you prioritise which courses need the most attention before finals.
How to Use the GPA Calculator
The GPA Calculator is designed to give you an accurate answer in seconds. Follow these steps:
- Step 1: Click "Add Course" to enter your first course. Type the course name (optional — for your own reference), select the letter grade you received or expect, and enter the credit hours for that course.
- Step 2: Repeat for each course you want to include. Add both completed courses and in-progress courses using expected grades to model your end-of-semester GPA.
- Step 3: Your cumulative GPA updates after every entry — no submit button needed. Try changing a grade to see exactly how much it moves the overall average.
- Step 4: Remove any course by clicking the delete button next to it. The GPA recalculates instantly.

How It Works
GPA = Σ(Grade Points × Credit Hours) ÷ Σ(Total Credit Hours)
GPA is a weighted average where each course's grade points are scaled by credit hours: Formula: GPA = Σ(Grade Points × Credit Hours) ÷ Σ(Credit Hours) Grade points on the standard 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 | F = 0.0 Example: Three courses — Biology (A, 4 credits), Calculus (B+, 3 credits), English (B−, 3 credits). Grade points: (4.0 × 4) + (3.3 × 3) + (2.7 × 3) = 16 + 9.9 + 8.1 = 34 Total credits: 4 + 3 + 3 = 10 GPA = 34 ÷ 10 = 3.40 A higher-credit course has proportionally more impact on your GPA. A 4-credit A pulls your average up more than a 2-credit A. This is why choosing to retake a high-credit course (if your institution allows grade replacement) can move a GPA significantly. The 4.0 scale is standard in the US and Canada; UK and Australian institutions use different grading systems.
Frequently Asked Questions
What is a good GPA in college?
3.0 (B average) is typically the minimum for academic standing. 3.5 and above is generally considered strong and qualifies for many honours distinctions. Graduate school and law/medical programs commonly require 3.0–3.5 minimum, with competitive programmes averaging admitted students at 3.7+. Context matters — a 3.2 in engineering is often viewed more favourably than a 3.2 in an unrelated field.
What GPA is a 3.5 equivalent to in letter grades?
A 3.5 GPA falls between B+ (3.3) and A− (3.7), roughly equivalent to a consistent B+/A− performance. It typically corresponds to earning mostly A's and B's with very few C's across your courses. On the 4.0 scale, it represents the top 20–30% of students at most universities and qualifies for Latin honours (cum laude) at many institutions.
How do I raise my GPA?
Focus your effort on high-credit courses — a 4-credit A has twice the impact of a 2-credit A. If your institution allows grade replacement, retaking a course where you earned a C or below can meaningfully move your cumulative GPA. Adding electives where you are confident of earning A's also helps. Use this calculator to model the exact GPA impact before committing to a plan.
Does a W (withdrawal) affect GPA?
In most US universities, a W (withdrawal before the deadline) does not affect GPA — it appears on your transcript but carries no grade point value. Withdrawing after the deadline may result in a WF (Withdrawal Failing), which counts as an F and damages your GPA. Check your institution's specific policies and deadlines before withdrawing from any course.
