GPA Calculator – Calculate Weighted Average on Different Scales
The GPA calculator computes weighted averages based on course completions, grades, or other values. Enter grades and their weights to get the final GPA.
The tool supports multiple scales: 0-4.0 (US GPA), 0-100% (percentage), and custom scales. You can calculate your entire academic career GPA or a single course final grade.
How is Weighted Average Calculated?
Weighted average is calculated by multiplying each value by its weight, adding the results, and dividing by the sum of weights. For example, exam (60% weight) grade A and project (40% weight) grade B: (4.0×0.6 + 3.0×0.4) = 2.4 + 1.2 = 3.6 GPA. The GPA calculator does this automatically.

- Also see the sum, count, and possibly the median.
- Add or remove numbers flexibly and the result updates in real time.
The arithmetic mean is the most common average, but it's sensitive to outliers.
- A single exceptionally large or small number can skew the average.
- The median might be a better measure of center if there are outliers in the data.
- A weighted average gives different results if values have different weights.
The calculator computes a simple arithmetic mean – other types of averages require different methods.
- Weighted grade averages require considering credit points.
- For decimal numbers, use either dots or commas according to your preference.
