Plain-English definitions of the finance terms that matter, each with a simple worked example. No circular definitions and no assumed knowledge — just what the term means and why it changes your decisions.
How to use these guides
Use these when a term appears in a loan document, a mutual fund statement or a tax form and the surrounding explanation assumes you already know it. Each entry defines the term, works a small example, and says why the term changes a decision.
They are deliberately short. If a definition needs three paragraphs to be useful, it is a guide rather than a glossary entry, and it lives in one of the other categories.
Where a term carries a tax or legal meaning as well as an everyday one — principal, cash flow, net worth — the entry gives the everyday sense first and flags the difference, because the stricter definition is the one that decides what you owe. Check the worked example against your own statement before acting on it.
