Personal finance guides
Practical articles to understand compound interest and make better decisions with your money, with links to our free calculators.
These guides exist for a simple reason: the calculators give you the number, but they don't tell you what to do with it. Here you'll find articles that explain, without jargon and with concrete examples, how compound interest works, how to take your first steps as an investor and how to build a retirement plan that doesn't rely on the state pension alone.
There are no magic formulas here and no get-rich-quick promises. The underlying mechanics are boring, and that's exactly why they work: start early, contribute every month, watch the fees and let time do the rest. Each guide links to its calculator so you can check what you read against your own figures: the compound interest calculator, the monthly savings calculator or the retirement calculator.
If a term doesn't ring a bell (CAGR, APR, the rule of 72...), it's explained in the glossary. And if you miss a guide, tell us through contact: the next ones will largely be decided by what readers ask for.
