Weighted Grade Point Average Calculator

A weighted grade average multiplies each course grade by that course’s credit (or ECTS, or weight), adds the products and divides by the total weight. High-credit courses influence the result more.

Formula Weighted average = (grade₁ × weight₁ + grade₂ × weight₂ + …) / (weight₁ + weight₂ + …)

Example: grades 80, 90, 70, 100 with credits 3, 2, 1, 4 give a weighted points sum of 80×3 + 90×2 + 70×1 + 100×4 = 890, total credit 10 and an average of 89.00. With equal credits (1, 1, 1, 1) the result is the plain mean, 85.00.

The tool supports up to 8 courses; the first is required and the others are optional (leave grade and weight at 0 for unused courses). Any grade scale works: enter 0–100 for a percentage system or 0–4 for a 4.0 system, but all grades must use the same scale. Universities convert letter grades to coefficients (e.g. A = 4.0) under their own regulations; do that conversion first and enter the coefficients. The result is rounded half-up to two decimals.

Example 2 (decimal grade): a 2-credit course graded 88.5 and a 1-credit course graded 91, plus two 1-credit courses entered with grade 0, give a weighted points sum of 88.5×2 + 91×1 = 268, total weight 5 and an average of 53.60. A course with weight above 0 counts even if its grade is 0; leave the weight at 0 for courses you are not using.

How to read the result The weighted average is on the same scale as the grades you enter (0–100 for a percentage system, 0–4 for a 4.0 system). Total credit/weight is the sum of the weights that took part; the weighted points sum is Σ(grade × weight), and the average is that sum divided by the total weight. The result is a convenience figure; your university's system is authoritative for the official average.
