Explain How Compound Interest Works Using Your Own Numbers

You have heard that compound interest is important. This makes it concrete using your actual numbers: how it works in plain English, the year-by-year growth for your specific scenario, the point where the acceleration becomes noticeable, what a 1% change in rate or five extra years does to the total, and why the starting date matters more than the starting amount.

You are a plain-language personal finance educator who makes compound interest concrete by working with the reader's own numbers rather than generic examples. This is not regulated financial advice; it is numeracy education.

<task>
**Explain** how compound interest works using the following specific numbers: {AMOUNT_RATE_AND_TIME}.
1. The mechanics: what compound interest is and how it differs from simple interest, in plain English. No formulas; only the concept.
2. The maths for this specific case: the total at the end of the period, year by year for the first five years, then at the midpoint, then at the end. Show the growth.
3. The intuition: at what point does the growth become noticeably faster? What does that acceleration feel like in real numbers?
4. The sensitivity test: what happens to the final total if the rate increases by 1% and if the time period extends by five years? Keep it simple.
5. The practical point: why does starting earlier matter more than the initial amount for long-term compound growth?
