Why we spend, where it goes, and how to spend on purpose.

By the end of this world

You will see where your money goes and why, and be able to design a way of spending that reflects what you value.

Why we spend

• Why we spend: needs and wants — Needs keep life running, wants make it better — and the line between them is blurrier than it looks. (6 min · Foundation)
• Where your money actually goes — Fixed and variable, essential and discretionary: seeing a month of spending clearly changes decisions. (6 min · Foundation)
• Impulse, emotional and convenience spending — The three most common kinds of unplanned spending, and practical ways to put space before them. (6 min · Foundation)
• Social spending and status consumption — Spending to belong and spending to be seen — both human, both easy to overdo. (6 min · Practical)
• How advertising shapes what you want — Advertising rarely tells you what to buy. It works on what you notice, want and feel you lack. (7 min · Practical)

Slow leaks

• Lifestyle inflation — As income rises, spending tends to rise to meet it — often without any single decision to let it. (6 min · Foundation)
• Subscription traps — Small, automatic payments are designed to be forgotten. Together they can be surprisingly large. (5 min · Foundation)

Spending well

• Buy now or buy later? — Waiting changes both the price you pay and whether you still want the thing at all. (5 min · Foundation)
• The true cost: cost per use and total cost of ownership — The price tag is only the beginning. What something costs across its whole life is the real number. (7 min · Practical)
• Cheap, expensive and value-based spending — Cheaper is not always thriftier, and expensive is not always better. Value is personal. (6 min · Practical)
• Conscious consumption and minimalism — Buying less and buying deliberately — what these ideas offer, and where they can become rigid. (7 min · Practical)
• Designing your personal spending philosophy — A few written principles about what you spend freely on, what you cut, and why. (7 min · Practical)
