Note: In the US, children's soap requires lead testing. This information is cited in the hyperdoc from a government website.
Here is a batch cost calculator available in both Google Sheets and Excel.
If you click the button to use the Google Sheets version, it will ask you to make a copy. The Excel version will download to your device when you click it.
