About This GPA Calculator
This GPA Calculator computes your weighted Grade Point Average on the standard 4.0 scale used by virtually all US colleges and universities. Add any number of courses with their letter grades and credit hours, and the calculator instantly produces your accurate weighted GPA — the same calculation your registrar uses on your official transcript. It is essential for semester planning, graduate school applications, scholarship eligibility checks, and academic standing monitoring.
The Formula — How It Works
The calculator uses the standard weighted GPA formula:
Standard grade point values on the 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. For example, a student with: Chemistry (B+, 4 credits = 13.2 points), English (A, 3 credits = 12.0 points), and History (C+, 3 credits = 6.9 points) has a GPA of (13.2 + 12.0 + 6.9) ÷ (4 + 3 + 3) = 32.1 ÷ 10 = 3.21.
Weighted vs Unweighted GPA — and the 4.0 vs 5.0 Scale
Weighted GPA (college definition): Credit hours weight each course — a 4-credit course has twice the GPA impact of a 2-credit course. This is what this calculator computes, and what virtually all colleges use.
Weighted GPA (high school definition): Sometimes refers to a 5.0 scale where AP/IB/honors courses earn extra grade points (A = 5.0 instead of 4.0). This is a different concept — this calculator uses the standard college 4.0 scale only.
Cumulative GPA includes all semesters from your first to your most recent. Semester GPA covers only one term. Both use the same formula — just different sets of courses. Use this calculator for either by entering only the courses you want to include.
Who Should Use This Calculator
This tool is for undergraduate and graduate students at US colleges and universities who need an accurate, instant GPA calculation. It is particularly useful for students who want to model "what if" scenarios — entering hypothetical final exam grades to see the minimum performance needed to reach a target GPA. It is also useful for parents supporting students, academic advisors running quick calculations, and students evaluating whether a course withdrawal or grade replacement makes mathematical sense.

When to Use This Calculator
Enter your current grades before finals to calculate what grades you need in each course to hit your target semester GPA — and prioritise where to focus study time.
Calculate your exact GPA to compare against program minimums, and model how remaining semesters could improve your cumulative GPA before applying.
Verify your GPA meets scholarship eligibility thresholds, and understand exactly what grades you need next semester to maintain or qualify for merit-based aid.
Calculate whether your current semester GPA will bring your cumulative GPA above the 2.0 minimum required to exit academic probation, and how many more credits at what grade level it will take.
Confirm your GPA calculation before listing it on a resume or job application, and understand whether it meets the minimum thresholds many employers require (commonly 3.0 or 3.5 for competitive positions).
💡 Pro Tips
Credit hours matter more than the number of courses. A 4-credit science lab where you earn a B contributes 12 grade points; a 1-credit PE elective where you earn an A contributes only 4. Prioritise performance in high-credit courses — they move your GPA far more than low-credit electives. Focus your study time accordingly.
A W (Withdrawal) on your transcript does not affect your GPA, but an F does — permanently — unless your school has a grade replacement policy. If you are in danger of failing, check your school's withdrawal deadline and talk to your advisor. Withdrawing is almost always better than earning an F, especially if you can retake the course.
Many institutions have grade forgiveness or course repeat policies that replace the original grade in GPA calculations. If your school allows grade replacement, strategically retaking 1–2 early low-grade courses in your major can significantly boost your cumulative GPA. Not all graduate programs or employers accept grade replacement — check their policies first.
Graduate programs and employers often look at your GPA by major or by upper-division coursework (junior/senior year), not just your overall GPA. A 3.0 overall with a 3.7 in your major is viewed very differently than a 3.0 overall with a 2.8 in your major. Calculate your major-only GPA separately to know your true academic strength in your field.
