What is your GPA, really? A plain average of your grades can be wrong because credit hours change the math. This free GPA calculator weighs every course by its credits and shows your semester and cumulative GPA as you type. Add your grades below. No sign-up.
GPA Calculator
Add your courses and see your semester and cumulative GPA right away. Use credits or per-course weights, and edit the grade scale to match your school.
Enter each course with its grade and credits. Course name is optional.

Key Takeaways
- Grade Points: the number your letter grade is worth. On the 4.0 scale, an A is 4.0 and a B is 3.0.
- GPA = Total Quality Points ÷ Total Credits
- Quality Points = Grade Points × Course Credits
- A 4-credit class moves your GPA more than a 2-credit class.
- Your cumulative GPA is not the plain average of your semester GPAs.
- Schools set their own scales, so you can edit the grade points in that calculator.
How to Use This GPA Calculator
- Choose how you enter grades. Use the tabs to enter letter grades, percentages, or grade points.
- Add your courses. Type a course name if you want one. Then pick the grade and enter the credits.
- Add more semesters. Select “+ Add Semester” to build a full cumulative GPA.
- Use weights if your courses count by percent. Turn on “Enable per-course weight (%)”. A bar shows how much weight you used and how much is left. Weights replace credits while this switch is on.
- Read your result. The ring shows your GPA, your letter average, and a short note on where it stands. You can copy, share, or download the result as a CSV file.
- Match your school. Open the grade scale below the tool to edit grade points, such as A+ = 4.3 or A- = 3.67.
Your entries stay on your device. The calculator does not send anything you type to a server.
What Your GPA Result Shows
After you enter a grade and credits for at least one course, the panel on the right shows your result. Each part means this:

Pass, no pass, incomplete, and withdrawn grades stay out of your GPA. A Pass still counts as earned credit.
How to Calculate GPA
Use this formula:
GPA = total quality points / total credits
Quality points for one course equal its grade points multiplied by its credits. Add the quality points for every course, then divide by the total credits. If you also need to calculate your percentage or letter grade from assignment scores, use our grade calculator.

49.7 |
Divide 49.7 by 14 credits. The semester GPA is 3.55.
The same classes without credit weighting would give a plain average of 3.50. The extra weight on the two 4-credit A grades lifts the real GPA.
The 4.0 GPA Scale
This is the most common version. Many US colleges and high schools use it.
| Letter | Percent | Grade points |
|---|---|---|
| A+ | 97-100 | 4.0 |
| A | 93-96 | 4.0 |
| A- | 90-92 | 3.7 |
| B+ | 87-89 | 3.3 |
| B | 83-86 | 3.0 |
| B- | 80-82 | 2.7 |
| C+ | 77-79 | 2.3 |
| C | 73-76 | 2.0 |
| C- | 70-72 | 1.7 |
| D+ | 67-69 | 1.3 |
| D | 63-66 | 1.0 |
| D- | 60-62 | 0.7 |
| F | Below 60 | 0.0 |
Some schools give an A+ 4.3 points. Others skip plus and minus grades. Your school may also set different percent cutoffs. Use your school policy as the final word, and see the full GPA scale and converter to switch scales.
Why Your Result Can Differ from Your Transcript
Schools set their own rules, so a calculator and a transcript can differ by a few hundredths. These are the usual reasons.
- Grade points. Many schools use 3.7 for an A- and 3.3 for a B+. Others use 3.67 and 3.33. The University of Florida advising center lists A- as 3.67, B+ as 3.33, and C- as 1.67. You can edit the grade points in the calculator to match your school.
- GPA hours. Your transcript shows GPA hours next to your GPA. Use those hours, not your total earned credits, when you check a result.
- Courses that do not count. Pass, no pass, incomplete, and withdrawn grades usually earn no grade points. The University of Florida tells students not to enter S-U courses in its calculator.
- Transfer and exam credit. Transfer grades and AP or IB exam credit can count toward your degree without counting in your GPA. It depends on the school.
- Retakes. A school may replace the old grade, average both attempts, or count only the best one.
When the calculator and your transcript disagree, trust your transcript. Then adjust the grade points or remove the courses your school leaves out, and compare again.
Semester GPA vs Cumulative GPA
Your semester GPA covers one term. Your cumulative GPA covers every term together.
To get a cumulative GPA, add the quality points from all semesters and divide by all credits. Do not average the semester GPAs unless every semester has the same number of credits.
Example: Semester 1 is a 3.0 GPA over 15 credits. Semester 2 is a 4.0 GPA over 12 credits.
- Average of the two GPAs: 3.50
- Real cumulative GPA: (3.0 x 15 + 4.0 x 12) / 27 = 93 / 27 = 3.44
Semester 1 has more credits, so it counts for more. If you already have a current GPA and credit total, use the cumulative GPA calculator to continue from there.
How to Calculate GPA on the Quarter System
The quarter system uses the same GPA formula as the semester system. Multiply each grade’s points by the course units, add the results, and divide by the total units. Type your quarter units into the credits field.
| Course | Grade | Grade points | Units | Quality points |
|---|---|---|---|---|
| BIO 1 | A- | 3.7 | 5 | 18.5 |
| ENG 1 | B | 3.0 | 4 | 12.0 |
| ART 10 | A | 4.0 | 3 | 12.0 |
| Total | 12 | 42.5 |
Divide 42.5 by 12 units. The quarter GPA is 3.54.
To combine quarter and semester records, convert the quarter units to semester units first. Multiply quarter units by 2/3, so these 12 quarter units equal 8 semester units. Without the conversion, quarter classes would count for too much. De Anza College publishes this conversion, and the quarter system runs across the University of California system and at Stanford.
Credits or Weights: Which Should You Use?
Use credits when your school lists credit hours or credit units. This fits most college and high school transcripts.
Use per-course weight (%) when each course counts as a share of the total, and those shares add up to 100%. The calculator then multiplies each grade by its weight and divides by the total weight used.
This weight is not the same as the bonus points for honors or AP classes. Bonus points raise the grade points of a hard class. The per-course weight changes how much a class counts in the average. For bonus points, use the weighted GPA calculator or the high school GPA calculator.
Weighted vs Unweighted GPA
An unweighted GPA treats every class the same. An A is 4.0 in every course.
A weighted GPA adds bonus points for harder classes. A common rule gives +0.5 for honors and +1.0 for AP, IB, or dual enrollment. Under that rule, an A in an AP class counts as 5.0.
Bonus rules differ by school. Check what yours uses before you rely on the number.
Other GPA Scales
This page uses the US 4.0 scale. Some schools use 4.3, some use 5.0 for weighted GPA, and other countries report percentages, 10-point CGPA, or letter bands. Conversion formulas differ by university. Use the GPA scale and converter for common conversions, and follow the receiving school’s formula when you apply.
What Is a Good GPA?
| GPA | What it usually means |
|---|---|
| 3.9 to 4.0 | Mostly A grades |
| 3.7 | Straight A- average |
| 3.5 or higher | Often the honors range |
| 3.0 | A B average |
| 2.0 | A common minimum for good academic standing |
A “good” GPA depends on your goal. Scholarships, graduate programs, and honors programs each set their own cutoff. Check the exact number for the one you want. Then use the target GPA calculator to see the grades you need.
How to Raise Your GPA
- Aim at the high-credit classes. A 4-credit course moves your GPA more than a 2-credit course.
- Set a target and calculate the grades you need. Say your GPA is 3.2 after 45 credits and you want 3.4 after 30 more credits. You need a 3.70 average across those 30 credits. If you want to know what score you need on an upcoming final exam to reach your target course grade, use our final grade calculator.
- Check your repeat policy. Some schools replace the old grade. Some average both attempts. Some keep both on the transcript.
- Plan withdrawals carefully. A W usually does not change your GPA, but you do not earn credit for that course. Ask your advisor first.
- Re-check your numbers each term. Small gains add up faster when you have fewer total credits.
