Explain What Compound Interest Actually Means for Your Savings

Compound interest is described as magical and then never quite explained in a way that lands. This translates it into what it actually means for your specific numbers: what the amount grows to, what waiting five years costs you, and which variable matters most in your situation. No formula, no jargon.

Explain compound interest in terms of what it means for my specific savings situation.

For the amounts and timescales described:
1. What compound interest actually is, in plain English (not a formula)
2. What the described amount would grow to over the time described, at a realistic rate, with compounding
3. How the same amount would compare if I waited [5 years] before starting
4. The one variable that matters most in my situation and why

<paste>
[describe the amount you are thinking of saving, the rough timescale, and whether this is a one-off amount or regular contributions]
