GPA Calculator
Add your courses, letter grades and credit hours and this GPA calculator works out your term GPA instantly. Switch to Cumulative mode to fold in the GPA you already have, or turn on weighting for Honors and AP classes.
Solid work — comfortably above average.
How to calculate GPA
- Convert each grade to points. 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.
- Multiply by credit hours. A grade in a 4-credit course counts four times as much as the same grade in a 1-credit course.
- Add and divide. Total grade points ÷ total credit hours = your GPA.
Example: Biology (A, 4 credits), History (B+, 3 credits) and Art (A−, 2 credits) give (4.0×4 + 3.3×3 + 3.7×2) ÷ 9 = (16 + 9.9 + 7.4) ÷ 9 = 33.3 ÷ 9 = 3.70. Our how to calculate GPA guide works through bigger examples, and how to find your GPA shows where your college publishes the official number.
Cumulative GPA: why it moves slowly
Your cumulative GPA is the same calculation stretched over every course you have ever taken. After 90 credits of 3.50 work, one 15-credit semester of straight A's only lifts you to about 3.57 — frustrating, but it also means one bad semester cannot wreck years of good work. Use Cumulative mode above to test scenarios: enter your current GPA and credits, then play with this term's grades to see what each outcome does to the final number.
Still in high school?
The maths is identical, but semesters, Honors/AP weighting and the 5.0 weighted scale matter more — use the high school GPA calculator, which is set up for that. And if your teachers grade in percentages, convert them with the grade calculator first.
Frequently asked questions
How to calculate GPA?
Convert each letter grade to grade points (A = 4.0, B = 3.0, and so on), multiply each by the course's credit hours, add everything together, and divide by the total credit hours. A student with an A in a 3-credit course and a B in a 4-credit course has (4.0×3 + 3.0×4) ÷ 7 = 3.43. The full step-by-step guide is in our blog post on how to calculate GPA.
How does the cumulative GPA calculator work?
Switch to Cumulative GPA mode and enter your current cumulative GPA and the credit hours you have already completed. Add this term's courses and the calculator blends the old and new together, weighting each by its credits — exactly how your college computes it.
What is the difference between a semester GPA calculator and a cumulative one?
A semester GPA calculator only counts one term's courses. A cumulative GPA covers every term so far, so it moves more slowly: the more credits you have completed, the less one semester can change it. This page does both — pick the mode at the top.
What GPA do colleges and employers consider good?
On the 4.0 scale, 3.5 and above is strong, 3.0–3.4 is solid, and below 2.0 usually triggers academic warnings. Many scholarships and honours programmes set their line at 3.5. Requirements vary, so check your own institution's scale.
Does this GPA calculator work for college courses?
Yes — this is a GPA calculator college students can use for any credit-hour system. Enter each course's letter grade and credit hours. Lab courses worth 1 credit and lectures worth 3 or 4 are handled correctly because every grade is weighted by its credits.
What is a weighted GPA?
A weighted GPA gives harder courses extra points: typically +0.5 for Honors and +1.0 for AP or IB classes, so a B in an AP course can count like a 4.0. Turn on the weighted switch above and set each course's level. Colleges often recalculate GPAs unweighted, so it is worth knowing both numbers.
How do I calculate my GPA if my school uses percentages?
Convert each percentage to a letter grade first using our grade percentage calculator, then enter the letters here. On the standard scale, 93%+ is an A (4.0), 90–92% an A- (3.7), 87–89% a B+ (3.3), 83–86% a B (3.0), and so on down to F (0.0).
