How It Works
The Weighted Average Calculator uses a straightforward formula to give you accurate results. Here's how it works:
- Step 1: Multiply each value by its corresponding weight.
- Step 2: Add up all the weighted values.
- Step 3: Divide the total weighted values by the total weights.
In simple terms: (Value₁ × Weight₁ + Value₂ × Weight₂ + ...) / (Weight₁ + Weight₂ + ...)
Here's a quick example table to show how it works in practice:
| Value | Weight | Weighted Value |
|---|---|---|
| 10 | 2 | 20 |
| 20 | 3 | 60 |
| 30 | 1 | 30 |
| Total | 6 | 110 |
The weighted average here would be 110 / 6 = 18.33. Easy, right?
