🎓 GPA Calculator
Calculate your semester GPA or cumulative GPA using the 4.0 scale.
Grade Scale Reference
| Grade | Points | Grade | Points |
|---|---|---|---|
| A+ | 4.0 | C+ | 2.3 |
| A | 4.0 | C | 2.0 |
| A- | 3.7 | C- | 1.7 |
| B+ | 3.3 | D+ | 1.3 |
| B | 3.0 | D | 1.0 |
| B- | 2.7 | F | 0.0 |
What Is a GPA Calculator?
A GPA (Grade Point Average) calculator converts your course grades and credit hours into a single numerical GPA on either a 4.0 or percentage scale. It weights each course by its credit hours — a 3-credit course counts for three times as much as a 1-credit elective — then averages across all courses to give you your semester GPA or cumulative GPA across your entire academic record.
The standard 4.0 scale assigns: 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. Weighted GPA adds extra points for honors, AP, or IB courses (typically 0.5–1.0 extra points), allowing students in rigorous programs to exceed 4.0 on the weighted scale. Most college admissions and scholarship programs specify which scale they're evaluating.
GPA matters beyond graduation. Graduate school admissions typically have minimum GPA cutoffs — most top MBA programs report median GPAs of 3.5–3.7, and medical school acceptance rates drop sharply below a 3.5 GPA. Many professional licensing exams and government employment programs have GPA requirements. Some employers, particularly in finance, consulting, and engineering, screen for 3.5+ GPA for entry-level positions, especially for candidates within 1–2 years of graduation.
Knowing your GPA at any point in the semester lets you make strategic decisions: whether a course withdrawal improves or hurts your standing, what grades you need in remaining courses to hit a target GPA by graduation, or whether retaking a course to replace a poor grade is worth the time investment.
How to Use This GPA Calculator
- Enter each course name — labeling courses helps you track which ones have the biggest impact on your overall GPA.
- Enter the credit hours — typically 1–4 per course. Lab courses, lectures, and seminars often carry different credit weights. Use the exact credit hours listed on your transcript.
- Enter the grade — use letter grades (A, B+, C, etc.) or the corresponding grade points if your institution uses a different scale. Some calculators also accept percentage grades.
- Add all courses for the semester — the calculator weights each grade by its credit hours and computes your semester GPA automatically.
- Calculate cumulative GPA — enter your previous GPA and total credits earned to combine with your current semester for an accurate running cumulative GPA.
Why Track GPA Throughout the Semester, Not Just at the End
Midterm grades are the right time to recalibrate. If you're sitting at a C+ in a 4-credit course that represents 40% of your semester hours, you can calculate exactly what final exam grade is needed to reach a target GPA — and decide whether to seek tutoring, drop the course, or shift study time. Students who track GPA proactively have more options than those who discover their situation only when final grades are posted.

Frequently Asked Questions
What GPA do I need for graduate school?
It depends on the program. Top MBA programs (Harvard, Wharton, Stanford) have median GPAs of 3.7–3.9. Law school at top-14 schools typically requires 3.7+. Medical school acceptance averages 3.7+ for GPA at most MD-granting institutions. Master's programs in STEM often have 3.0–3.2 minimum cutoffs with competitive admits averaging 3.5–3.7. A lower GPA can be offset by strong GRE/GMAT/MCAT scores, research experience, or a strong upward GPA trend in your final years — demonstrating improved academic performance can matter as much as the raw number.
How much can one bad grade hurt my GPA?
It depends on your total credit hours. A D in a 3-credit course when you have 30 total credits completed drops a 3.5 GPA by approximately 0.10 points. That same D when you have 90 credits completed only drops it by about 0.03 points. This is why early semesters matter more — poor grades in freshman year carry higher weight because the denominator (total credits) is small. Conversely, strong grades late in your program can meaningfully recover a GPA that suffered early on.
Should I retake a course to improve my GPA?
Many institutions allow grade replacement or GPA recalculation after retaking a course — but policies vary widely. Some schools average both grades; others replace the old grade. Before retaking, calculate the GPA impact: if you have 90 credits and one C in a 3-credit course, replacing it with an A only improves your GPA by roughly 0.07 points. The time and tuition cost of retaking rarely makes sense unless the subject is foundational for graduate school prerequisites (like organic chemistry for pre-med) or your target school specifically recalculates retaken grades.
What is the difference between semester GPA and cumulative GPA?
Semester GPA reflects only the current term's courses. Cumulative GPA is a weighted average across all semesters, incorporating every course you've taken. Employers and graduate schools typically care about cumulative GPA, but a strong upward trend (low freshman GPA improving to a high senior GPA) is also meaningful context. Academic probation and dean's list honors are usually determined by semester GPA, making each term's performance independently important even for students with strong cumulative standing.
How do pass/fail courses affect GPA?
Pass/fail (or credit/no credit) courses typically do not affect GPA — a "Pass" grade earns credit hours but adds zero grade points to the GPA calculation. This makes pass/fail enrollment a strategic option for exploratory courses or during high-stress semesters where protecting your GPA matters more than the grade itself. Some schools limit how many pass/fail credits you can take toward degree requirements. Graduate schools and professional programs often view a high proportion of pass/fail courses skeptically, as it obscures the difficulty of your academic record.
