Money is not one big scary thing. It is a jigsaw made of nine pieces. Some of them you already know. Some of them you have been quietly dreading. The trick is working out which piece is on your mind right now, picking it up, and leaving the rest until you actually need them.
You do not need to learn personal finance end-to-end before you make a decision. You need to know which piece you are holding. Pick the one that matches the question in your head, read what it covers, and follow the links to the chapters, questions and tools that sit underneath it. If you are not sure where to start, the ten questions pathway is built for exactly that — every one of these pieces shows up somewhere in there.
Click a piece and you will land on its shelf — the full stack of questions, courses, eBooks and posts sitting underneath it.
The nine pieces
1. Foundations
What it covers: The maths and mental models that sit underneath every money decision — percentages, interest (simple, compound, rule of 72), time value of money, probability vs odds, risk and risk-based pricing, cognitive bias, opportunity cost, net worth, how banks actually work, foreign currency and exchange rates, and enough spreadsheet literacy to plan a month.
Why it matters: Most money mistakes are not moral failings, they are maths mistakes and bias mistakes. Fix the foundations and the rest becomes easier.
2. Getting Set Up
What it covers: The practical onboarding nobody teaches you — opening a bank account, Know Your Customer (KYC), the electoral roll, writing a will, healthcare and the NHS, tax basics (PAYE, tax codes, payslips, National Insurance, self-assessment), and the price comparison sites that save you money on everything else.
Why it matters: If the admin is not in place, nothing else works. This is the piece you pick up first when you leave home, start work, or realise you have been winging it.
3. Earning
What it covers: Income, work, pay, tax, benefits and the welfare state, and the student loan reframed as a graduate tax rather than a debt.
Why it matters: You can only optimise what comes in if you understand how it is taxed, what you are entitled to, and what your negotiating position actually is.
4. Spending
What it covers: Budgeting frameworks, bills and utilities, shopping smarter, the coffee factor and lifestyle creep, consumer protections, and the cost-of-living chapter that explains why things feel the way they do.
Why it matters: Most of the “where did it all go” feeling is solved here. Get this piece right and the savings and investing pieces get a lot easier.
5. Saving
What it covers: Emergency funds, rainy-day funds, sinking funds, cash ISAs, and the difference between saving (short-term, safe, boring) and investing (long-term, risky, less boring).
Why it matters: This is the buffer that stops a car repair turning into a payday loan. Everybody needs one. It does not have to be huge to start with.
6. Investing
What it covers: The long game — getting started, building a portfolio, tax wrappers (Stocks and Shares ISA, LISA, SIPP), pensions, investment tax, risk tolerance, and the expensive mistakes most new investors make in their first year.
Why it matters: Compound interest is the most important idea in personal finance, and the earlier you start, the less you need to put in. This is where time, not money, is the superpower.
7. Borrowing and Credit
What it covers: Credit scoring and credit reference agencies, credit cards, personal loans, overdrafts, Buy Now Pay Later, store cards, payday loans, identity theft, and mortgages as a product.
Why it matters: Borrowing is not bad — borrowing badly is. Knowing how credit works and how it is priced is the difference between a cheap mortgage and a rejected application.
8. Protecting
What it covers: Insurance across the board (motor, home, contents, travel, life, income protection), scams and fraud, gambling, the mental-health side of money, fees and fine print, and protecting the people who depend on you.
Why it matters: This is the piece most people ignore until they need it. Think of it as the boring stuff that stops an ordinary bad week turning into a life-defining one.
9. Life Events
What it covers: The big forks in the road — running and buying a car, travel and travel money, going to university (and whether university is right for you), starting work, renting, buying a home, and getting on the housing ladder.
Why it matters: Most of your expensive decisions happen at the edges of a life change. This is the piece you reach for when something big is about to happen, not after.
A note on the four nations
Money rules are not the same in England, Scotland, Wales and Northern Ireland. Where differences matter — student loans, property taxes, NHS prescriptions, and a few others — each chapter flags them. You do not need a separate jigsaw piece for this; you need to know to check.
Every piece will point you to the chapters, questions and tools that sit under it. Some of them are live today. Some are coming soon and marked as such. If you want a guided route instead of picking a piece, start with the ten questions pathway. If you want to know where this whole thing is going, the about page explains the plan.
