GPA Calculator — Calculate Grade Point Average for US and International Grading
GPA (Grade Point Average) is the standard measure of academic performance used by universities across the United States, Canada, and many other countries. A single number encapsulates performance across multiple courses, weighted by their credit hours. The free GPA calculator on PublicSoftTools computes your semester GPA, cumulative GPA, and shows you exactly what grades you need to reach a target GPA.
Standard 4.0 GPA Scale
| Letter grade | Percentage range | Grade points | Notes |
|---|---|---|---|
| A+ | 97–100% | 4.0 | Most institutions treat A+ as 4.0; some use 4.3 on the extended scale |
| A | 93–96% | 4.0 | Excellent; Dean's List typically requires 3.5+ GPA |
| A− | 90–92% | 3.7 | High distinction; some employers screen for 3.5+ GPA |
| B+ | 87–89% | 3.3 | Good above average |
| B | 83–86% | 3.0 | Good average; many graduate programmes require 3.0+ |
| B− | 80–82% | 2.7 | |
| C+ | 77–79% | 2.3 | |
| C | 73–76% | 2.0 | Satisfactory; minimum for most major requirements |
| C− | 70–72% | 1.7 | |
| D+ | 67–69% | 1.3 | |
| D | 60–66% | 1.0 | Minimum passing grade at many institutions |
| F | Below 60% | 0.0 | Fail; may need to retake; impacts cumulative GPA |
How to Use the GPA Calculator
- Open the GPA calculator.
- For each course, enter the course name (optional), letter grade or percentage, and credit hours (also called credit units or semester hours).
- Click Add course to add more rows for each class taken that semester.
- For cumulative GPA: enter your current cumulative GPA and total credit hours completed, then add the current semester's courses. The tool combines both to project your new cumulative GPA.
- Use the target GPA field to see what grades you need on remaining courses.
How GPA Is Calculated
GPA is a credit-weighted average of grade points. For each course: multiply grade points by credit hours to get "quality points." Sum all quality points and divide by total credit hours.
GPA = Total quality points / Total credit hours
Example semester (three courses):
- Calculus (4 credits): B+ = 3.3 → quality points: 4 × 3.3 = 13.2
- Literature (3 credits): A = 4.0 → quality points: 3 × 4.0 = 12.0
- Chemistry (3 credits): B− = 2.7 → quality points: 3 × 2.7 = 8.1
Semester GPA = (13.2 + 12.0 + 8.1) / (4 + 3 + 3) = 33.3 / 10 = 3.33
Cumulative GPA Calculation
Cumulative GPA covers all semesters combined. It is computed using all quality points and credit hours from every term:
Cumulative GPA = Sum of all quality points / Sum of all credit hours
Example: After two semesters:
- Semester 1: GPA 3.4, 15 credit hours → quality points: 3.4 × 15 = 51.0
- Semester 2: GPA 3.1, 12 credit hours → quality points: 3.1 × 12 = 37.2
- Cumulative GPA: (51.0 + 37.2) / (15 + 12) = 88.2 / 27 = 3.27
Note that the semester with more credit hours has proportionally more influence. A strong semester with more courses pulls the cumulative GPA up more than a strong semester with fewer courses.
GPA Requirements and Thresholds
| Purpose | Typical GPA threshold | Context |
|---|---|---|
| Graduate school admission | Most programmes require 3.0+; top programmes 3.5+ | GPA + GRE/GMAT + personal statement collectively assessed |
| Employer screening | Some firms (especially finance, consulting) screen for 3.5+ | More important for entry-level than experienced hiring; less common at tech companies |
| Scholarships and awards | Varies; many require 3.0–3.5 minimum | Merit scholarships often require maintenance of minimum GPA |
| Academic probation | Below 2.0 typically triggers warning | Sustained below-2.0 GPA may result in academic suspension or dismissal |
| Athletic eligibility (US) | 2.0 minimum for NCAA eligibility | Student-athletes must maintain academic standards to play |
| Dean's List / Honours | Typically 3.5–3.7+ for semester or cumulative | Varies by institution; usually requires full-time enrolment too |
Weighted vs. Unweighted GPA
Unweighted GPA (4.0 scale)
The standard 4.0 scale treats all courses equally. An A in a first-year introductory course counts the same as an A in an advanced elective. Most university GPAs are unweighted on the 4.0 scale.
Weighted GPA (high school, US)
Many US high schools use a weighted GPA that gives extra grade points for advanced courses (AP, IB, dual enrolment). A common system adds 1.0 point for AP courses: an A in AP Calculus = 5.0, not 4.0. This means weighted GPAs can exceed 4.0, and the maximum possible weighted GPA varies by school.
When colleges receive transcripts, they typically recalculate GPA on an unweighted 4.0 scale for fair comparison. The calculator supports both systems.
Grade Replacement and Repeated Courses
Most US universities offer grade forgiveness or grade replacement policies: if you retake a course, the new grade replaces the old in GPA calculations, though both may remain on the transcript. Policies vary:
- Some schools replace the grade only for the first repeat
- Some only count the higher grade
- Some average both grades
- Federal financial aid calculates satisfactory academic progress differently from GPA — check your institution's specific policy
Pass/Fail and Credit/No Credit Courses
Courses taken as Pass/Fail or Credit/No Credit typically do not affect GPA — they count toward credit hours but are excluded from quality point calculations. This can be a strategic option for electives outside your major that let you explore without risk to GPA.
How Many Credits to Recover GPA?
Recovering a low GPA takes time because past grades dilute future improvements. If your cumulative GPA is 2.5 after 60 credit hours, and you want to reach 3.0:
- Total quality points at 2.5 GPA with 60 hours: 2.5 × 60 = 150
- To reach 3.0 after n more hours all at A (4.0): (150 + 4n) / (60 + n) = 3.0
- 150 + 4n = 180 + 3n → n = 30 credit hours of straight A's
This illustrates why early semesters matter so much — poor performance early requires many high-performing semesters to overcome. The GPA calculator's "target GPA" feature shows exactly how many credit hours of what grades are needed to reach your goal.
Common Questions
What GPA do you need for medical school?
US medical school (MD) applicants typically need a cumulative GPA of 3.7+ for competitive programmes and a science GPA (Biology, Chemistry, Physics, Math courses) of 3.5+. Average MCAT scores are also heavily weighted. DO (osteopathic) programmes have slightly lower average GPA requirements (~3.5), and Caribbean schools accept lower GPAs but with different residency match outcomes.
Do transfer students keep their GPA from the previous institution?
This varies by institution. Some schools start your GPA fresh at zero for courses taken at the new institution. Others carry over the previous GPA. Many professional school applications (medical, law, business) calculate a combined GPA across all undergraduate institutions using AMCAS, LSAC, or similar application systems.
What is the difference between semester GPA and cumulative GPA?
Semester GPA (also called term GPA) covers only the courses in a single semester or term — it resets each new term. Cumulative GPA is the running average across all terms at the institution. Employers and graduate schools typically look at cumulative GPA, though a strong upward trend (low early, high late) can be explained in interviews or personal statements.
