What is GPA?

GPA (Grade Point Average) is a standardized number that represents your academic performance. In the US, GPA is calculated on a 4.0 scale where each letter grade is assigned a point value — A = 4.0, B = 3.0, C = 2.0, D = 1.0, and F = 0.0. Your GPA is the weighted average of these points across all courses.

Schools use two types: unweighted GPA (standard 4.0 scale) and weighted GPA (up to 5.0, with bonuses for Honors and AP/IB courses). Colleges, scholarships, and employers use GPA to evaluate academic achievement.

How to Calculate GPA

  1. 1
    List your courses. Write down each course you took during the semester or year.
  2. 2
    Convert grades to points. A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0. For +/- grades, add or subtract 0.3 (e.g., B+ = 3.3, B- = 2.7).
  3. 3
    Multiply by credit hours. Multiply each grade point by the credit hours for that course to get quality points.
  4. 4
    Add up totals. Sum all quality points and all credit hours separately.
  5. 5
    Divide. Total quality points ÷ total credit hours = your GPA.

Example: If you earned a B (3.0) in a 4-credit course and an A (4.0) in a 3-credit course: (3.0 × 4 + 4.0 × 3) ÷ (4 + 3) = 24 ÷ 7 = 3.43 GPA.

Which GPA Calculator Should I Use?

College students: Use the College GPA Calculator. It handles variable credit hours (a 4-credit lab course weighs more than a 1-credit seminar) and calculates on the standard 4.0 scale.

High school students (unweighted): Use the High School GPA Calculator if your school uses a simple 4.0 scale without course-type bonuses. Most report cards show this number.

High school students (weighted): Use the Weighted GPA Calculator if your school gives extra points for Honors (+0.5) and AP/IB (+1.0) courses. This calculator shows both weighted and unweighted side by side.

Middle school students: Use the Middle School GPA Calculator. Same 4.0 scale, simpler interface. Starting to track your GPA early gives you a head start for high school planning.

Frequently Asked Questions

What is the difference between weighted and unweighted GPA? +
Unweighted GPA uses a standard 4.0 scale where an A = 4.0 regardless of course difficulty. Weighted GPA adds bonus points for harder courses — typically +0.5 for Honors and +1.0 for AP/IB classes — so it can exceed 4.0.
Which GPA calculator should I use? +
Use the College GPA Calculator if you're in college (credit hours vary per course). Use the High School GPA Calculator for standard unweighted GPA. Use the Weighted GPA Calculator if your school uses Honors/AP/IB weighting. Use the Middle School GPA Calculator for grades 6-8.
How do colleges calculate GPA for admissions? +
Most selective colleges recalculate your GPA using their own scale. They look at both the GPA number and the rigor of your course load. A 3.7 weighted GPA with 8 AP classes is generally viewed more favorably than a 4.0 unweighted GPA without advanced courses.
What is a good GPA? +
For Ivy League and top 20 schools, a weighted GPA of 4.0+ with multiple AP/IB courses is expected. Top 50 universities look for 3.7-4.0+. State universities are competitive at 3.0-3.5. For college students, above 3.5 is strong and above 3.0 is the minimum for most graduate programs.
Can I raise my GPA? +
Yes. Focus on courses where you can realistically improve, retake low grades if your school allows it, and prioritize credit-heavy courses since they have more impact on your overall GPA. Even a single semester of strong grades can shift your cumulative GPA significantly.
Do employers look at GPA? +
Some employers check GPA for entry-level roles, especially in finance, consulting, and engineering (typically requiring 3.0+). After 2-3 years of work experience, GPA matters much less. Graduate schools weigh GPA more heavily.
What is the GPA scale? +
The standard US GPA scale runs from 0.0 to 4.0, where A = 4.0, B = 3.0, C = 2.0, D = 1.0, and F = 0.0. Weighted scales extend to 5.0 by adding +0.5 for Honors and +1.0 for AP/IB courses.
