Frequently Asked Questions

When should I use weighted mean?

Use weighted mean when some values contribute more to the final result than others—like grades (credits matter) or investment portfolios (position size matters). A simple average treats all values equally; weighted average respects their relative importance.

How is weighted average different from simple average?

A simple average sums all values and divides by count. A weighted average multiplies each value by its weight, sums the results, then divides by the total weight. Example: a 3-credit A and a 1-credit B gives a weighted average of 3.75, not 3.5.

How do I calculate a weighted GPA using this calculator?

Enter each course grade as a value and its credit hours as the weight. For example, value=4.0 (A), weight=3 credits. Add all courses and the calculator computes your GPA-style weighted average automatically.
