Free GPA Calculator for High School & College
Calculate unweighted and weighted grade point averages instantly. Customize course credits, AP/IB/Honors weights, and simulate cumulative semester standing with complete privacy.
How was this GPA calculated?
Grade Point Average (GPA) is computed by dividing total quality points earned by total credit hours attempted:
Each course earns quality points equal to its credit hours multiplied by its numeric grade point value (e.g., 3 credits × 4.0 for an A = 12.0 quality points).

How to Calculate Your GPA Step-by-Step
A Grade Point Average (GPA) is the credit-weighted arithmetic mean of all numeric grade points earned over an academic term or entire degree program.
The Standard GPA Formula
Step 1: Convert Letter Grades to Grade Points
Convert each class letter grade to its numeric grade point value on the 4.0 scale (e.g., A = 4.0, B = 3.0, C = 2.0).
Step 2: Calculate Course Quality Points
Multiply the credit hours of each course by its numeric grade point value. For example, a 4-credit course with an A earns 4 × 4.0 = 16.0 quality points.
Step 3: Sum Quality Points and Total Credits
Add all quality points earned across all courses, and add all credit hours attempted.
Step 4: Divide Total Points by Total Credits
Divide total quality points by total credit hours and round to two decimal places (e.g., 45.0 quality points ÷ 15 credits = 3.00 GPA).

Frequently Asked Questions
Clear, factual answers to common questions about college and high school GPA calculations.
Grading scales vary significantly by institution. In most standard college and high school systems using plus/minus modifiers, 80-82% is assigned a B- (2.7 grade points). In simple 10-point scale systems without minuses, 80-89% is a flat B (3.0 grade points). In weighted high school AP/IB classes, an 80% can earn up to 3.7 or 4.0 weighted grade points. Always verify your school district or university registrar rubric.
On a common 4.0 reference scale, a 3.4 GPA falls between a B and B+. The interpretation depends on your institution, major, and academic goals. Dean’s List requirements and scholarship thresholds vary by school, so check your institution’s specific policies.
A C+ typically represents scores in the 77% to 79% range. It indicates satisfactory academic mastery above the minimum passing benchmark. While 2.3 is standard across most U.S. institutions, some universities use 2.333 or omit plus/minus modifiers entirely.
Most secondary and post-secondary institutions map 70-72% to a C- (1.7 grade points). In schools without plus/minus grading, 70-79% constitutes the full C bracket (2.0 grade points). Always verify with your institution’s official handbook.
In the United States, standard unweighted GPAs cap at 4.0, and weighted GPAs rarely exceed 5.0 or 6.0. However, some international systems (such as in Australia or certain specialized honors matrices) utilize a 7.0 scale where 7.0 represents High Distinction (the highest possible academic mark).
Class rank percentiles depend heavily on whether a high school weights grades for honors and AP/IB courses. In schools with extensive weighted coursework, the top 1% often holds weighted GPAs between 4.5 and 5.0. On an unweighted 4.0 scale, top 1% typically requires straight A’s (4.00). In colleges, Latin honors cutoffs (such as Summa Cum Laude) vary by university and major, typically requiring between 3.90 and 4.00. There is no universal GPA cutoff for the top 1%.
On an unweighted scale, the maximum is always 4.0 (all A’s). However, many high schools award a 1.0 quality point bonus for AP/IB courses (turning an A from 4.0 to 5.0). A student taking exclusively AP/IB courses and earning straight A’s will graduate with a 5.0 weighted GPA.
Maintaining an unweighted 4.0 requires earning an A or A+ in every single class without receiving a single A- (on strict plus/minus scales) or B. How common a 4.0 GPA is varies by school, cohort, academic level, and grading policy.
