Investing

Notes, calculators, and real-world lessons I’ve collected on long-term investing. Built to play with, not just to read.

What works for me may not work for you, and none of this is financial advice.

Calculators

Plug in numbers, see what happens.

Project growth with a custom rate, or pick a real asset and a historical window.

What actually happened to money in different scenarios — and what to take from it.

What happens to $10k in a bank account over 30 years.

When buying gold pays off — and when it doesn’t.

When buying a flat actually beats renting and investing the difference.
