GPA Calculator — Weighted & Unweighted

What Is a GPA Calculator?

A GPA calculator converts letter grades and credit hours into a Grade Point Average, the standard metric used by colleges, universities, and employers to evaluate academic performance. Whether you are applying to graduate programs, competing for scholarships, or simply tracking your progress, knowing your exact GPA is essential.

This free tool supports two modes: an unweighted 4.0 scale (where every class is treated equally) and a weighted 5.0 scale (which awards extra points for honors, AP, and IB courses). You can quickly calculate your semester GPA and use the results to project your cumulative average over multiple terms.

Unweighted vs. Weighted GPA — What's the Difference?

Unweighted GPA (4.0 Scale)

On an unweighted scale, an A in any class equals 4.0 points, regardless of the course difficulty. This means an A in Regular English and an A in AP Physics are valued the same. Most public high schools report unweighted GPAs, and many colleges recalculate GPAs on this scale to create a level playing field.

Weighted GPA (5.0 Scale)

A weighted GPA accounts for course rigor. Honors courses typically receive a 0.5-point boost, while AP and IB courses receive a full 1.0-point boost. So an A in an AP class is worth 5.0 instead of 4.0. This system rewards students who challenge themselves with advanced coursework, and many competitive universities value this metric during admissions.

How to Use This GPA Calculator

  1. Select your mode — choose Unweighted (4.0) or Weighted (5.0).
  2. Enter each course — type the course name, select the letter grade, and input the number of credit hours.
  3. If using weighted mode, select the course type (Regular, Honors, or AP/IB).
  4. Add more courses as needed with the "+ Add Course" button.
  5. Click "Calculate GPA" to see your semester GPA, total credits, and quality points.

Understanding the GPA Scale

The standard unweighted conversion used by most U.S. institutions is as follows:

  • 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

Quality points for each course are calculated as grade points × credit hours. The GPA is then the sum of all quality points divided by total credit hours.

Why Your GPA Matters

Your GPA has a direct impact on college admissions, scholarship eligibility, honor-roll status, and even job prospects. Here's a quick overview of common thresholds:

  • 3.5–4.0 — Dean's list, top scholarship consideration, competitive grad school programs.
  • 3.0–3.49 — Solid standing, eligible for many scholarships and internship programs.
  • 2.0–2.99 — Satisfactory, meets minimum requirements for most institutions.
  • Below 2.0 — Academic probation at many schools; may risk losing financial aid.

Tips for Improving Your GPA

  • Prioritize high-credit courses — an A in a 4-credit class boosts your GPA far more than an A in a 1-credit elective.
  • Retake strategically — many schools replace the old grade when you retake a course.
  • Use the study hours calculator — plan your study time effectively to improve performance across all subjects.
  • Take advantage of office hours — direct interaction with professors can clarify material and boost grades.
  • Choose honors/AP wisely — on a weighted scale, even a B in an AP class (3.0 + 1.0 = 4.0) matches a regular A.

Frequently Asked Questions

Can I calculate my cumulative GPA across multiple semesters?

Yes. Enter all courses from every semester you want to include. The calculator will combine them into a single GPA. Alternatively, you can calculate each semester separately and combine them manually using the quality-points method.

Do colleges prefer weighted or unweighted GPA?

Most U.S. colleges recalculate your GPA on their own scale. However, they do consider course rigor, so taking AP/IB classes can still help your application even if the college uses an unweighted GPA.

What about pass/fail courses?

Pass/fail courses typically do not affect GPA. They count as credit hours earned (if passed) but are not included in GPA calculations. If your school handles them differently, check with your registrar.
