Grade Calculator
Calculate your weighted grade average and GPA on a 4.0 scale. Supports percentage and letter grade inputs.
How to Calculate
Weighted Average = Σ(score × weight) ÷ Σ(weight)
The weighted grade average multiplies each score by its weight (credits), sums the results, and divides by the total weight. GPA converts letter grades to a 4.0 scale using standard grade point values.
Frequently Asked Questions
How do I calculate my weighted grade?
Multiply each score by its weight (credits), add them all up, then divide by the total weight. For example, if you scored 90 (3 credits) and 80 (2 credits): (90×3 + 80×2) ÷ (3+2) = 86.
How is GPA calculated?
GPA is calculated by converting letter grades to grade points (A=4.0, B=3.0, etc.), multiplying by credit hours, summing, and dividing by total credits. A 4.0 is the highest possible GPA on the standard scale.
What is the difference between weighted and unweighted GPA?
Unweighted GPA treats all classes equally (4.0 scale). Weighted GPA gives extra points for honors or AP courses (e.g., an A might be worth 5.0 instead of 4.0). This calculator uses the standard unweighted 4.0 scale.
