GPA Calculator

Calculate your cumulative Grade Point Average (GPA) using standard letter grades (A+ to F). Add unlimited courses, assign credits, and instantly see your academic standing. Customize grade points, plan future targets, and export your data.

Unweighted GPA uses standard 4.0 scale (A+ = 4.0, A = 4.0, A- = 3.7 ... F = 0.0). Weighted GPA adds extra points for advanced courses (example: A+ = 4.5, A = 4.5, A- = 4.2, ...). You can fully customize grade points below.
Quick examples:
⭐ Perfect semester (4.0)
? STEM heavy (3.5)
? Mixed grades (3.0)
⚠️ Need improvement (2.3)

Understanding Grade Point Average (GPA)

Your Grade Point Average (GPA) is a standardized measure of academic achievement, widely used by high schools, colleges, and universities. It converts letter grades into numerical values on a 4.0 scale, then averages them weighted by course credits. This tool calculates both unweighted GPA (all courses equal) and weighted GPA (extra points for honors, AP, IB). You can also customize the grade point values to match your school's policy.

\( \text{GPA} = \frac{\sum (\text{Grade Points} \times \text{Credit Hours})}{\sum \text{Credit Hours}} \)

For example, a 3-credit course with grade A (4.0) contributes 12 quality points. If total credits are 15 and total quality points 48, GPA = 48/15 = 3.2.

Standard 4.0 Grade Conversion Table

Letter Grade Percentage Range (typical) Unweighted Points Weighted Points*
A+ / A 93–100% 4.0 4.5
A- 90–92% 3.7 4.2
B+ 87–89% 3.3 3.8
B 83–86% 3.0 3.5
B- 80–82% 2.7 3.2
C+ 77–79% 2.3 2.8
C 73–76% 2.0 2.5
C- 70–72% 1.7 2.2
D+ 67–69% 1.3 1.8
D 60–66% 1.0 1.5
F <60% 0.0 0.0

* Weighted points shown are an example for honors/AP courses. Actual policies vary by school; use the Weighted tab and the Customize grade points button to match your institution's exact scale.

International Grade Conversion (approx)
  • Percentage → 4.0: 90-100% = 4.0, 80-89% = 3.0, 70-79% = 2.0, 60-69% = 1.0
  • IB Diploma: 7 = 4.0, 6 = 3.7, 5 = 3.0, 4 = 2.0, 3 = 1.0
  • UK Honours: First-class = 3.7-4.0, Upper second (2:1) = 3.3-3.6, Lower second (2:2) = 2.7-3.0
  • Indian Percentage: divide by 20, subtract 1 (e.g., 80% → 3.0). Varies by institution.
Real‑life Case Study: Raising a 2.8 GPA

Alex finished freshman year with 30 credits and a 2.8 GPA (84 quality points). To reach a 3.2 cumulative after 60 total credits, Alex needed 108 quality points in sophomore year — a 3.6 average over 30 new credits. By focusing on higher‑credit courses and retaking one failed class, Alex succeeded. Use the Goal planner to simulate your own path.

Why Use an Interactive GPA Calculator?

  • Academic planning: Plan your semester to meet scholarship or honor society requirements.
  • College applications: Understand how your current GPA aligns with target university averages.
  • Progress tracking: Keep a cumulative record across semesters by adding all your courses.
  • Weighted vs unweighted clarity: Differentiate between raw academic performance and extra-weighted advanced courses.

Proven Strategies to Raise Your GPA

1. Focus on High-Credit Courses

A 4-credit course affects your GPA four times more than a 1-credit course. Prioritize excelling in classes with higher weight.

2. Retake Low Grades

Many colleges allow grade replacement for retaken courses. Replacing an F (0.0) with an A (4.0) can dramatically boost cumulative GPA.

3. Use Summer/Winter Sessions

Taking easier courses during intercession can raise GPA without overloading fall/spring schedules.

4. Seek Academic Support

Tutoring, study groups, and office hours can convert a B to an A.

5. Plan a Balanced Schedule

Avoid overloading with too many difficult courses in one term. Mix challenging and manageable classes.

6. Consider Pass/Fail Strategically

If your school allows, use P/F for courses that don't count toward major to protect GPA.

Frequently Asked Questions

Unweighted GPA treats all courses equally (max 4.0). Weighted GPA gives extra points for honors, AP, or IB courses (e.g., A = 5.0 at some schools). Our Weighted tab uses a standard +0.5 boost for advanced classes; you can adjust points using the Customize button.

Absolutely. The same 4.0 scale applies to most middle and high schools. Graduate schools often consider a 3.0 minimum; the calculation method remains identical.

Pass/fail (P/F) courses typically do not affect GPA. You can omit them from the calculator or assign 0 credits. For non‑graded courses, just don't include them.

You can still use this calculator by converting your percentage or letter grade to the equivalent 4.0 scale using the provided conversion table. Alternatively, use the Customize grade points feature to set your school's exact values.

Simply add all courses from previous semesters as separate rows. The calculator sums total credits and quality points to give you a cumulative GPA. You can also export your course list for record keeping.
