College GPA Calculator
Free college GPA calculator: enter courses, letter grades and credit hours for your semester GPA on the 4.0 scale plus your new cumulative GPA.
If you’re staring at a syllabus at 1 a.m. trying to work out whether this semester sinks your average, the calculator above does the arithmetic in a few seconds. Add a row for each course, pick the letter grade, enter the credit hours, and it returns your semester GPA on the standard 4.0 scale: A 4.0, A- 3.7, B+ 3.3, B 3.0, and so on down to F 0.0. Enter your prior cumulative GPA and prior total credits and it also returns the new cumulative GPA you’d carry into next term, plus your running credit total and where you land against common honors cutoffs. One honest caveat before you panic or celebrate: grading scales are set by each institution, not by a national standard. This tool estimates using the most widely used scale. Your registrar’s scale is the one that governs your transcript.
How do I calculate my college GPA by hand?
Multiply each course’s grade points by its credit hours, add those products together, then divide by total credit hours. An A in a 3-credit course contributes 4.0 × 3 = 12 points. A 15-credit term totaling 51.3 quality points works out to 51.3 ÷ 15 = 3.42. The calculator above runs this for every row at once and updates the moment you change a grade, which beats redoing the division.

Frequently Asked Questions
How do I calculate my college GPA by hand?
Multiply each course’s grade points by its credit hours, add those products together, then divide by total credit hours. An A in a 3-credit course contributes 4.0 × 3 = 12 points.

Does an A+ count as more than 4.0?
That depends entirely on your institution, and both practices are common. Arizona State’s registrar assigns A+ a value of 4.33 but caps the reported cumulative GPA at 4.00. Swarthmore awards an A+ yet scores it 4.00, identical to a plain A. The calculator above uses 4.0 for A+, the more widespread convention. Check your registrar’s grading page if your school lists A+ separately.
How many credits does it take to raise a 2.8 GPA to a 3.0?
With 60 credits already earned, twelve credits of straight A grades moves 2.80 to exactly 3.00. At a 3.5 semester average it takes 24 credits instead. With only 30 credits on your record, six credits of A does it. The requirement scales with how much is already on your transcript, which is why early repairs are cheaper. Enter your own prior GPA and credits above to test your case.
