Enter your courses, credit hours, and letter grades into the calculator above to get your GPA instantly. The tool works for high school and college, handles weighted and unweighted scales, and updates your result as you add each course.
Your GPA (grade point average) is the single number colleges, scholarships, and graduate programs use to measure academic performance. Whether you need a quick check before the semester ends or want to plan how a retake could help, this calculator gives you a reliable estimate in seconds.
Calculate Your GPA by Entering Each Course and Grade
Start by adding one row per course. For each row, enter:
- Course name (optional, but helps you keep track)
- Credit hours or units for that course
- Letter grade you earned or expect to earn
The calculator multiplies each course's grade points by its credit hours, totals everything, and divides by your total credit hours. Your GPA appears immediately.
If you want your cumulative GPA across multiple semesters, enter your current GPA and total credits earned so far, then add the courses you are taking this semester. The tool combines both sets of data into one updated number.
Do Pass/Fail classes affect GPA? In most grading systems, Pass/Fail courses do not count toward GPA. A "Pass" earns credit hours but adds no grade points. Only letter-graded courses factor into the calculation, so you can leave Pass/Fail classes out of the calculator.
Do electives, PE, and arts classes count toward GPA? If your school assigns a letter grade and credit hours to the class, it counts. Check your transcript to confirm which courses carry graded credit.
How GPA Calculation Works on the 4.0 GPA Scale
Grade points, letter grades, and weight per course
Each letter grade corresponds to a number on the 4.0 scale:
| Letter Grade | Grade Points |
|---|---|
| A or 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 |
Some schools treat an A+ as 4.3 instead of 4.0. Check your school's handbook or registrar page to confirm which value applies.
How is the GPA calculated? Multiply each course's grade points by its credit hours. That gives you the quality points for the course. Add up all quality points, then divide by total credit hours. The result is your GPA.
Is a 93% a 4.0 GPA? It depends on your school's grading system. Many schools convert 93% and above to an A, which equals 4.0. Some set the A threshold at 90% or 94%. Your institution's grading scale is the one that matters.
What is 70% in GPA? On most common scales, 70% falls in the C range, which equals a 2.0. Some schools map 70% to a C minus (1.7). Check the percentage-to-letter conversion your school uses.
Is 80% what GPA? An 80% typically maps to a B minus (2.7) or B (3.0), depending on the specific scale your school follows.
Semester GPA vs. cumulative GPA
Your semester GPA covers only the courses in a single academic term. Your cumulative GPA covers every graded course since you started at the school (or across your entire high school career).
Think of semester GPA as a snapshot and cumulative GPA as the running average. Colleges and employers almost always look at the cumulative number.
To calculate your cumulative GPA, you need two things from your transcript: your total grade points earned so far and your total credit hours attempted. The calculator above handles this when you enter your current GPA and total credits, then add new courses.
Do 9th-grade grades count toward cumulative GPA? Yes. Most high schools include all four years in the cumulative GPA. Some colleges recalculate GPA using only certain courses, but your transcript will reflect everything from 9th grade onward.
Calculate Your High School GPA: Unweighted and Weighted
Unweighted GPA on the 4.0 scale
An unweighted GPA treats every class the same. An A in a regular course and an A in an AP course both earn 4.0 grade points. The maximum unweighted GPA is 4.0.
Most high schools report an unweighted GPA on the official transcript. It provides a straightforward comparison: the same scale, regardless of course difficulty.
What is a good GPA? Context matters, but generally a 3.0 (B average) is considered solid. A 3.5 or above is competitive for many colleges. The national average GPA for high school students is around 3.0, though this varies by school and district.
What is the highest GPA? On an unweighted scale, 4.0 is the maximum. On a weighted scale, it is commonly 5.0, though some schools allow up to 5.3 for A+ grades in AP or IB courses.
Weighted GPA for academic and honors classes
A weighted GPA gives extra grade points for harder courses. The most common approach:
- Regular courses: standard 4.0 scale
- Honors courses: add 0.5 (so an A = 4.5)
- AP, IB, or dual-enrollment courses: add 1.0 (so an A = 5.0)
This means a student earning all A's in AP classes could reach a 5.0 weighted GPA.
How do AP, Honors, and IB classes affect GPA? They boost weighted GPA because they carry extra grade points. They do not change unweighted GPA. Taking harder courses and earning B's can still produce a higher weighted GPA than earning A's in all regular classes.
Can you get a GPA higher than 4.0? Only on a weighted scale. If your school weights honors or AP courses, your GPA can exceed 4.0. On an unweighted scale, 4.0 is the ceiling.
How do colleges view weighted vs. unweighted GPA? Many admissions offices look at both numbers. Unweighted GPA shows raw academic performance. Weighted GPA shows willingness to take challenging courses. Some colleges recalculate GPA using their own formula, so the number on your transcript may not be the final number they use.
Calculate GPA for College, State University, and Grading Systems
How grading systems and credit hours affect your average
College courses are measured in credit hours (sometimes called units or semester hours). A typical lecture course is 3 credit hours. Labs, seminars, and studios vary.
Credit hours matter because a 4-credit course has more influence on your GPA than a 1-credit course. The calculator weights each grade by its credit hours automatically.
How do I calculate GPA if my school uses credits? The same formula applies. Multiply grade points by credit hours for each course, sum the quality points, and divide by total credit hours. This works whether your school calls them credits, units, or semester hours.
Some schools outside the US use percentage grades instead of letter grades. If your institution uses a different scale, convert each grade to its 4.0 equivalent before entering it. Many schools publish a conversion chart on the registrar's website.
What is a Cum Laude GPA? Latin honors vary by school, but common thresholds are:
- Cum Laude: 3.5 to 3.69
- Magna Cum Laude: 3.7 to 3.89
- Summa Cum Laude: 3.9 to 4.0
Your school may set different cutoffs. Check with your registrar.
Semester GPA calculation for each academic term
To find your semester GPA, include only the courses from one term. This is useful for checking academic standing, since many programs require a minimum GPA each semester to remain in good standing or keep financial aid.
If you want to project what you need on remaining coursework, enter your anticipated grade for each course. The calculator will show what your semester GPA would be under that scenario. This is especially helpful late in the term when you are deciding where to focus study time.
Repeated courses and how they repeat in your GPA calculation
How schools calculate GPA when you repeat a course
Policies for repeated courses vary widely. The three most common approaches:
- Grade replacement: Only the new grade counts toward GPA. The original attempt stays on your transcript but is excluded from the GPA calculation.
- Grade averaging: Both the old and new grades count. Your GPA reflects the average of both attempts.
- Both grades count separately: Each attempt adds credit hours and grade points to the total, just like any other course.
Most state university systems and community colleges use some form of grade replacement, but limits often apply (for example, only the first three repeats qualify). Check your school's handbook for the exact policy.
Can a bad grade be replaced if I retake a class? At many schools, yes. The new grade replaces the old one in the GPA calculation, though the original grade may still appear on your transcript. Some schools only allow replacement if the new grade is higher.
Enter repeated courses and check your transcript
When using the calculator, enter the course the way your school would count it. If your school uses grade replacement, enter only the most recent grade and its credit hours. If both attempts count, enter each attempt as a separate row.
Your official transcript is the best reference. It will show which grades are marked as repeated and which ones factor into your cumulative GPA. If you are unsure, contact your registrar before making academic decisions based on a projected GPA.
How to calculate GPA manually without a calculator
The manual calculation: total grade points and credit hours
The formula is straightforward:
GPA = Total Quality Points / Total Credit Hours
Here is how to do it step by step:
- Write down each course, its credit hours, and the letter grade you earned.
- Convert each letter grade to grade points using the table above.
- Multiply grade points by credit hours for each course. This gives you the quality points for that course.
- Add up all the quality points.
- Add up all the credit hours.
- Divide total quality points by total credit hours.
Example:
| Course | Credits | Grade | Grade Points | Quality Points |
|---|---|---|---|---|
| English 101 | 3 | A (4.0) | 4.0 | 12.0 |
| Biology 110 | 4 | B+ (3.3) | 3.3 | 13.2 |
| History 200 | 3 | B (3.0) | 3.0 | 9.0 |
| Art 105 | 2 | A− (3.7) | 3.7 | 7.4 |
- Total quality points: 12.0 + 13.2 + 9.0 + 7.4 = 41.6
- Total credit hours: 3 + 4 + 3 + 2 = 12
- GPA: 41.6 / 12 = 3.47
The calculator on this page runs the same formula instantly. The manual method is useful when you want to understand exactly where each number comes from.
GPA calculator estimates, not official school calculations
This GPA calculator provides an estimate based on the data you enter. It is a planning tool, not an official academic record.
Your school's registrar is the only source for your official GPA. Differences can occur because of rounding rules, grade replacement policies, or courses excluded from GPA (like Pass/Fail or transfer credits). Always consult your transcript or academic advisor for decisions about graduation requirements, financial aid eligibility, or admissions applications.
Use this calculator to explore scenarios, plan your course load, and set realistic academic goals. For anything that requires an exact, verified GPA, check with your school directly.
