For entertainment purposes only. This is a projection, not a forecast. It assumes a constant monthly return applied to your balance — real returns vary month to month, include losing months, and are never guaranteed. Top-ups are assumed added at the start of each month and earn that same month. Figures are gross of any fees, spreads, slippage, swaps, or tax (e.g. UK CGT on withdrawn profits). Use it to understand the mechanics of compounding, not as a promise of results. Trading carries risk of loss. Nothing here is financial advice.
