GPA Calculator
Calculate your high school GPA on both a standard 4.0 unweighted scale and a weighted scale (up to 5.0 or 6.0) for Honors, AP, and IB classes.

Standard Unweighted Scale (4.0)
Used by most colleges to compare students fairly, regardless of course difficulty.
| Letter | GPA Points | Percentage |
|---|---|---|
| A+ | 4.0 | 97-100% |
| A | 4.0 | 93-96% |
| A- | 3.7 | 90-92% |
| B+ | 3.3 | 87-89% |
| B | 3.0 | 83-86% |
| B- | 2.7 | 80-82% |
| C+ | 2.3 | 77-79% |
| C | 2.0 | 73-76% |
| C- | 1.7 | 70-72% |
| D+ | 1.3 | 67-69% |
| D | 1.0 | 63-66% |
| D- | 0.7 | 60-62% |
| F | 0.0 | Below 60% |
Standard Weighted Scale (5.0 Max)
Adds 0.5 points for Honors and 1.0 points for AP/IB/College level classes.
| Letter | Regular | Honors | AP / IB |
|---|---|---|---|
| A+ / A | 4.0 | 4.5 | 5.0 |
| A- | 3.7 | 4.2 | 4.7 |
| B+ | 3.3 | 3.8 | 4.3 |
| B | 3.0 | 3.5 | 4.0 |
| B- | 2.7 | 3.2 | 3.7 |
| C+ | 2.3 | 2.8 | 3.3 |
| C | 2.0 | 2.5 | 3.0 |
| C- | 1.7 | 2.2 | 2.7 |
| D+ | 1.3 | 1.8 | 2.3 |
| D | 1.0 | 1.5 | 2.0 |
| D- | 0.7 | 1.2 | 1.7 |
| F | 0.0 | 0.0 | 0.0 |
Weighted vs Unweighted GPA
An unweighted GPA uses a standard 4.0 scale and does not consider course difficulty. An A in AP Calculus and an A in Gym both count as a 4.0. A weighted GPA adds extra points for harder classes (like Honors or AP), allowing students to achieve a GPA higher than 4.0 to reflect their rigorous course load.
How colleges view your GPA
Most colleges recalculate your GPA using their own internal system. Many selective colleges focus primarily on your unweighted GPA to compare you fairly with applicants from different high schools that may have different weighting systems. However, they absolutely look at the rigor of your course schedule alongside your GPA.
The danger of chasing a weighted GPA
Taking too many AP or Honors classes can backfire if your grades drop. A “B” in an AP class (3.0 unweighted) looks worse to a college than an “A” in a regular class (4.0 unweighted), even though the weighted GPA might favor the AP class. Balance is key: take the hardest classes you can handle while still maintaining strong grades.
What if my school weighs differently?
Some high schools give +1.0 for both Honors and AP. Others use a 6.0 scale. This calculator defaults to the most common system (+0.5 Honors, +1.0 AP) but includes an “Advanced” option (+1.0 Honors, +2.0 AP) for schools with more aggressive weighting. Check your school’s profile or course catalog to confirm their specific policy.
What is a High School GPA Calculator?
A high school GPA calculator is a tool that computes your Grade Point Average for a semester or your entire high school career. Unlike college GPA calculators which factor in credit hours, high school GPA is typically calculated by averaging the grade points of all your classes equally, making it simpler but requiring accurate tracking of course types (Regular, Honors, AP).
Why students use this tool
Students use GPA calculators to set academic goals, project their future GPA based on expected grades, and understand how taking an AP or Honors class will impact their overall average. It is also used by high school counselors to help students plan their schedules and ensure they meet the GPA requirements for college admissions, athletic eligibility, or scholarships.
How cumulative GPA works in high school
Your cumulative GPA is the average of every class you have taken from freshman year to senior year. It is calculated by adding up the total grade points for all classes and dividing by the total number of classes. This calculator handles cumulative calculations by allowing you to input your previous number of classes and past GPA, then mathematically combining it with your current semester grades.
Understanding the math
For each class, you earn a base point (e.g., 4.0 for an A). If it is an Honors class, you add 0.5 points. If it is an AP class, you add 1.0 point. The unweighted calculation ignores these bonuses. The weighted calculation includes them. To find your GPA, sum all the points and divide by the number of classes. If you have a 4.0 unweighted GPA, it means you earned an A in every single class you ever took.
Who this calculator is for
This calculator is designed for high school students, parents, and guidance counselors. The mobile-friendly layout makes it easy to use on a phone in the hallway or during a counseling session. By showing both weighted and unweighted results side-by-side, it helps students make informed decisions about course selection and understand exactly how colleges will evaluate their transcript.
