Can I use this calculator for weighted averages if my percentages come from groups of different sizes?

Yes. The tool automatically switches to weighted-average mode when you enter weights alongside your percentage values, computing the combined average based on the sample sizes you provide.

Is there a limit to how many percentage values I can enter?

You can enter up to ten percentage values, each with its own optional weight, allowing you to average a moderate-sized dataset without manual re-entry.

Do I need to create an account to save or share my results?

No account is required. The calculator is free to use, and you can share results instantly via the provided link or clear the fields at any time.

What happens if I leave the weight fields blank?

If no weights are entered, the calculator treats all percentages equally and computes a simple arithmetic mean of the values provided.
