**Option 1: Concise & Direct (Best for general usage)**

**Choosing the Best Option:**

* **Context is King:** Consider the overall topic of your website. If you’re primarily focused on finance or economics, a longer description might be suitable. If your website is more general, the shorter explanations probably work well.
* **Target Audience:** Think about how familiar your readers are with financial concepts. If you have a broader audience, simpler language might be best, such as Option 4.
* **SEO:** Keywords like “利息計算” (interest calculation), “貸款利息” (loan interest), “銀行利息” (bank interest) are naturally incorporated or could be add in if needed to the descriptions to enhance SEO.
