Compounding
The single mathematical idea that does most of the work in long-term wealth building. The articles below are about preserving and accelerating it.
Compounding is the maths that converts ordinary saving into life-changing wealth. £300 a month at a 7% real return for thirty years becomes £350,000. Stretch that to forty years and it's £750,000. The same £300 a month at 5% real (which is closer to a realistic post-fee global tracker assumption) is £270,000 after thirty years. The gap between those numbers is what fees, taxes, and behaviour do to your eventual pot.
These articles cover what shapes the curve. Stealth Taxes UK covers how the British tax system quietly eats compounding through fiscal drag and frozen thresholds. Junior ISA UK covers the wrapper that compounds for eighteen years on a child's behalf. The Slight Edge covers the habit framework that makes the saving rate possible. What Is a 100-Bagger Stock? is the equity-side equivalent: how individual companies compound over decades.

How War Debt Felled the British Empire

What Is a 100-Bagger Stock? Mayer's Framework (UK)
The median 100-bagger took 26 years to play out. Almost no retail investor sat through that. Mayer's four traits are easy to spot, and almost impossible to hold to maturity.
The Slight Edge Review: Small Habits, Big Wealth
Most people wait for the big break. Jeff Olson argues the big break is a myth, and the tiny daily action you keep dismissing is the only thing that ever moves the number.
