Major Purchase Decision Framework: Should I Buy It?
Large purchases are small decisions made big by money. A price tag is hard to judge on its own, so this framework asks the questions that put it in context: would you still want it in 30 days, what will it really cost to own, and what else could the money do.

- 2.What does it replace, and what will it cost per use?
- 3.What else could that money do for you?
What people commonly miss
- •Buying to solve a feeling rather than a need
- •Ignoring running, maintenance, and upgrade costs
- •Anchoring on the sale price instead of the real need

Common questions
How do I decide whether a big purchase is worth it?
Wait long enough to see whether the want holds, estimate cost per use over its life, include running and upgrade costs, and compare it with what else the money could do.
What is the 30-day rule?
A simple way to separate impulse from need: write down what you want to buy and wait 30 days. If you still want it and can afford it, it is more likely to be a considered decision.
