CalcSimpler Examples
- Scores 80, 90, 75 with weights 1, 2, 1 ⇒ 83.75
- Values 10, 20, 30 with weights 1, 1, 1 ⇒ 20
- Grades 70, 85, 90 with weights 3, 2, 1 ⇒ 79.17
FAQ
Skip values?
Use zero for unused inputs.
Do weights need to sum to 1?
No. Any positive weights work; the calculator normalizes them.
Can weights be percentages?
Yes, but they don't have to total 100%.
Additional Information
- Weights don't need to add up to 1 or 100; the formula normalizes them automatically.
- Set unused values and weights to 0 if you only have one or two data points.
- Useful for grade calculations, investment portfolios, and more.
