How Much Money Is Enough?

Ask people how much money would be enough and the reliable answer, across almost every income level ever surveyed, is about twice what they currently have. This holds for the person earning very little and, more remarkably, for the person earning a great deal. The number is not a quantity. It is a ratio, and a ratio can never be satisfied, because doubling your income doubles the target on the day it arrives.

The mechanism is not greed. It is that spending expands into available income almost silently — a slightly better flat, a slightly newer car, the restaurant you now consider normal — and within about eighteen months the new level feels like baseline rather than luxury. Economists call it the hedonic treadmill; anyone who has had a raise calls it Tuesday. The pleasure was real and it was temporary, and the raised costs were permanent.

The research on money and wellbeing is more nuanced than either camp likes to admit. Below the point where bills are frightening, money buys enormous relief — this is not disputed and it is not trivial, and telling a struggling person that money does not buy happiness is a specialised form of cruelty. Above that point the curve does not go flat exactly, but it bends hard, and what continues to matter is not the amount but what it is spent on: time, autonomy, distance from things you hate, and other people.

That is the practical hinge. Money spent on things reliably disappoints because things become background within weeks. Money spent on time — a shorter commute, help with the tasks you dread, the ability to say no to work — reliably does not, because it buys back hours that get spent on everything else. People who deliberately purchase time report higher satisfaction than people who purchase objects at the same cost, and almost nobody does it, because time purchases leave no evidence on the driveway.

The single most useful exercise is also the least fashionable: write the number down. Not an aspiration — an actual annual figure that covers your real life, plus the buffer that lets you sleep, plus a little for pleasure. Written down, the number stops being a ratio and becomes a fixed target that can be reached, which is why the exercise makes people uncomfortable. A moving goal cannot fail. A written one might arrive, and then you would have to decide what the rest of your life is for.

Enough is not an amount. It is a decision, made once, in advance, by a person who is not currently being advertised to. Everybody who has ever made it says the same odd thing afterwards: the money did not change and the wanting stopped.
