Weighted Average Calculator
Weighted Average Calculator
A Weighted Average Calculator is a practical mathematical tool that calculates an average where each value contributes according to its assigned importance or weight. Unlike a simple average, where every value has equal significance, a weighted average gives more influence to values with larger weights. This method is widely used in education, finance, business, statistics, inventory management, and scientific research.
Whether you are calculating course grades, GPA-style scores, investment returns, product ratings, or performance metrics, a Weighted Average Calculator simplifies the calculation and provides accurate results within seconds.
Our free Weighted Average Calculator allows you to enter multiple values and their corresponding weights to instantly calculate the weighted average, weighted sum, total weight, highest value, and lowest value. All calculations are performed directly within your browser for maximum privacy and speed.
What Is a Weighted Average?
A weighted average is an average in which each value contributes proportionally according to its assigned weight. Higher weights have a greater impact on the final result than lower weights.
For example, if one exam counts for 50% of your final grade while another counts for only 20%, the first exam has a greater influence on your overall score.
Weighted averages are commonly used in:
- School and college grading.
- GPA calculations.
- Financial analysis.
- Inventory valuation.
- Business reporting.
- Research studies.
- Survey analysis.
- Performance evaluations.
Why Use a Weighted Average Calculator?
Calculating weighted averages manually becomes more complicated as the number of values increases. A Weighted Average Calculator performs these calculations instantly and minimizes calculation errors.
It helps students, teachers, accountants, analysts, researchers, and business professionals obtain accurate weighted averages quickly.

How Does the Weighted Average Calculator Work?
The calculator multiplies each value by its corresponding weight, adds the weighted values together, and divides the result by the total weight.
- Enter the first value and its weight.
- Enter the second value and its weight.
- Enter the third value and its weight.
- Click the Calculate button.
- The weighted sum is calculated.
- The total weight is determined.
- The weighted average is displayed instantly.
- An interactive Chart.js visualization summarizes the entered values.
All calculations are performed locally within your browser without transmitting your data.
Weighted Average Formula
The calculator uses the standard weighted average formula.
Weighted Average = ฮฃ(Value ร Weight) รท ฮฃ(Weights)
Where:
- Each value is multiplied by its assigned weight.
- The weighted values are added together.
- The total is divided by the sum of all weights.
Example Calculation
Suppose you have the following scores:
- Assignment = 85 (Weight 30)
- Midterm = 90 (Weight 40)
- Final Project = 78 (Weight 30)
The calculator computes:
- Weighted Sum = (85 ร 30) + (90 ร 40) + (78 ร 30)
- Total Weight = 100
- Weighted Average = 84.90
The calculator performs these calculations automatically and presents the results in an easy-to-read format.
