Explain How Compounding Works in Practical Terms

Everyone knows compound interest is powerful and almost no one has seen the numbers in a form that made them actually start their pension at 22. This explains compounding through four worked examples with specific figures: the cost of starting ten years late, the hidden drag of a slightly higher annual fee, the difference a small monthly increase makes, and the one move this week that costs the least and returns the most over time.

<task>
**Explain** compound growth in plain language with four worked examples.
1. What compounding is: the one-paragraph plain-language explanation, with the key distinction from simple interest
2. The small difference that time makes: a worked example showing two people who invest the same monthly amount but start at different ages, and how different their outcomes are at 65
3. The fee drag: how an annual fund charge of 0.2% versus 1.5% affects a 30-year investment of the same starting amount
4. The contribution effect: how increasing monthly contributions by a small amount early makes a disproportionate difference over 30 years
5. The one action the reader can take this week to put compounding to work
