What is the GPA Score Calculator?
Your Grade Point Average (GPA) is a single number that summarizes your academic performance across multiple courses. Because courses can carry different credit hours, GPA is a credit-weighted average — a 4-credit course counts more than a 1-credit course. This calculator uses the common 4.0 scale where A = 4.0, B = 3.0, C = 2.0, D = 1.0 and F = 0.0.
How to use it
For each course, enter the grade points (the 4.0-scale value for the letter grade earned) and the number of credit hours. Leave any unused rows blank. The calculator multiplies grade points by credits for each course, adds them up, and divides by the total credits to produce your GPA, along with the total credits and total grade points.
The formula explained
$$\text{GPA} = \frac{\sum (\text{Grade Points} \times \text{Credits})}{\sum \text{Credits}} = \frac{g_1\,c_1 + g_2\,c_2 + \cdots + g_5\,c_5}{c_1 + c_2 + \cdots + c_5}$$ The numerator is your total "quality points." The denominator is the total credits attempted. Dividing the two yields a weighted average that respects how heavy each course is.
Worked example
Suppose you took three courses: an A (4.0) worth 3 credits, a B (3.0) worth 4 credits, and an A- (3.7) worth 3 credits. Quality points $$= (4.0\times3) + (3.0\times4) + (3.7\times3) = 12 + 12 + 11.1 = 35.1.$$ Total credits \(= 3 + 4 + 3 = 10\). GPA \(= 35.1 \div 10 = 3.51\).
FAQ
What if my school uses a different scale? Convert each letter grade to its 4.0-scale equivalent before entering it. Schools using a 4.3 or 4.5 scale should enter those raw values; the math still works.
Do I include credits for failed courses? Yes — a failing grade (F = 0.0) still counts in total credits, which lowers your GPA.
What's the difference between weighted and unweighted GPA? This tool computes a credit-weighted GPA. A simple unweighted average ignores credit hours; here courses with more credits influence the result more.
