Features like this would really benefit from in game text explaining it.
I feel it should be explained in two locations:
1. A “Mechanics” tab in the encyclopedia. A mechanic could be explained in mathematical terms what exactly a mechanic is, such as

2. Immersive dialogue prompt:
“My lord, I am honored to lead a party in our clan’s name. It will, of course, need substantial funding for the first few days to acquire appropriate supplies. Can the clan commit to —— money for ——- days in order to secure our success? After which we shall depend on our own wits for financial security”
