How to use

Enter values and weights, then click Calculate. Everything runs in your browser — nothing is uploaded or stored.

How is it calculated?

Each value times its weight, summed, then divided by total weight.

Do weights need to add to 100?

No — any weights work; they are normalized automatically.
